As aforementioned, the control device 100 described in
The control device 100 which may include at least one of those components may control various lamps provided on the vehicle.
Referring to
For example, the lamps may include head lamps 155 provided on a front side of the vehicle to irradiate visible light in a forward direction of the vehicle, rear lamps 154 provided on a rear side of the vehicle to emit visible light in a backward direction of the vehicle, and turn indicator lamps 156.
The rear lamp 154 and turn indicator lamp 156 are irrelevant to the present disclosure, and thus the detailed description thereof will be omitted.
The headlamp 155 may be turn on when a user request is received through the lamp drive unit 754 or input unit 120 as described above. When the headlamp 155 is turned on, light (visible light) may be irradiated toward in a forward direction of the vehicle 700.
As an example, when a low-beam output request is received by a user request, the headlamp 155 may irradiate low-beam in a forward direction of the vehicle 700. The low-beam may form a preset cut-off line, and the cut-off line may have various shapes according to the design.
Furthermore, the headlamp 155 may irradiate high-beam in a forward direction of the vehicle 700 when a high-beam output is requested by a user request. When a high-beam output is requested, in general, high-beam may be irradiated along with low-beam, a region irradiated with high-beam and a region irradiated with low-beam may overlap with each other on a partial portion thereof.
In some implementations, the low-beam or high-beam may be irradiated in a forward direction of the vehicle by the control of the control device 100. For example, when a light output request is received through the lamp drive unit 754 or input unit 120, the processor 170 of the control device 100 may control the headlamp 155 to allow the headlamp 155 to output light in a forward direction of the vehicle.
Furthermore, the headlamp 155 may be turned on when the ambient brightness is lower than the reference brightness by the sensing unit 160. For example, when the brightness adjacent to the vehicle that is sensed through the sensing unit 160 is lower than a preset brightness, the processor 170 may control the headlamp 155 to irradiate light in a forward direction of the vehicle.
In some implementations, the headlamp 155 may be formed to change a light irradiation direction.
For example, the headlamp 155 may change the direction of irradiating light (light irradiation direction) by the control of the processor 170 of the control device 100.
For example, the processor 170 may control the headlamp 155 to irradiate light irradiated from the headlamp 155 in an upward direction (for example, heightwise direction (H)) based on a preset condition (for example, user manipulation or surrounding environment) in a state that light outputted from the headlamp 155 is irradiated in the lengthwise direction (D).
In the above, it is taken as an example in which the light irradiation direction of the headlamp 155 is changeable in an upward direction, but the present disclosure may not be necessarily limited to this, and the headlamp 155 may change the light irradiation direction in all directions.
The light irradiation direction of the headlamp 155 may be changed (varied) by at least one of various constituent elements (for example, a light source, a reflector, a shield, a formed body or a lens) forming the headlamp 155, or changed (varied) through a deformable member formed on a housing of the headlamp 155 or at an outside of the headlamp 155.
Hereinafter, the controlling (changing, varying) of the light irradiation direction of the headlamp 155 by the processor 170 may be carried out at least one of the constituent elements, housing and deformable member of the headlamp as described above.
The technology of varying the light irradiation direction of the headlamp may correspond to a general technology, and thus the detailed description thereof will be omitted.
In some implementations, the headlamp 155 associated with the present disclosure may include a plurality of light sources. In the headlamp 155, the plurality of light sources may be provided in a matrix form or the plurality of light sources may be provided in a micro form. Furthermore, the plurality of light sources may be formed in a matrix form in the size of micro units.
The plurality of light sources may be respectively a halogen lamp, a light emitting diode (LED) or a laser diode (LD).
The plurality of light sources may be individually controlled. The processor 170 may individually (or independently) control the plurality of light sources.
Here, individually controlling the plurality of light sources may include the meaning of individually turning on/off the plurality of light sources, individually adjusting the irradiation brightness (or amount of output light) or individually varying the light irradiation direction.
For example, the processor 170 may allow part of the plurality of light sources to be irradiated in a first irradiation direction and the rest of the plurality of light sources to be irradiated in a second irradiation direction different from the first irradiation direction.
As another example, the processor 170 may be configured to control part of the plurality of light sources to be irradiated toward a front side of the vehicle, and the rest of the plurality of light sources to be irradiated on a sign sensed by the sensing unit 160. When the sensed sign is located in a side front direction or upper front direction of the vehicle, the headlamp 155 of the vehicle may irradiate light in two directions.
In some implementations, the head lamp 155 of the present disclosure may be formed to output lights of different colors. The head lamp 155 of the present disclosure may be formed to output light of at least one of a plurality of colors.
The processor 170 may detect an environment of the vehicle 700 through the sensing unit 160. The processor 170 may also control the head lamp 155 to output light of a preset color, based on the environment detected through the sensing unit 160. The environment may relate to either outside or inside conditions of the vehicle.
For example, the sensing unit 160 may detect a peripheral environment of the vehicle 700. The detecting of the peripheral environment may include the sensing unit 160 receiving (acquiring, sensing, extracting, detecting, deciding, or determining) information related to the peripheral environment of the vehicle.
For example, the environment sensed by the sensing unit 160 may include a type of a road surface (e.g., a paved road, an unpaved ground, etc.) on which the vehicle 700 is located, a state of weather, information related to a line indicated on the road surface (e.g., a color of the line, a type of the line, etc.), a type of a peripheral light source outside of the vehicle, just to name a few examples.
As another example, the environment sensed by the sensing unit 160 may include an environment inside the vehicle 700. For example, the sensing unit 160 may sense characteristics of a driver driving the vehicle (e.g., demographic characteristics or physical characteristics of the driver) or whether a particular user input has been received (or whether a user request has been received).
As such, detecting an environment of the vehicle may include detecting not only an external environment (e.g., a state, condition related to an external environment) of the vehicle 700 but may also include an internal environment (e.g., a state, condition related to an internal environment) of the vehicle 700.
An operation of detecting the environment of the vehicle may be performed by combining one or two or more of various sensors described above, such as a camera included in the sensing unit 160, a laser sensor, a radar, a lidar, and an ultrasonic sensor.
The sensing unit 160 of the present disclosure, as described above, may be the sensing unit 760 provided in the vehicle or may be a separate sensing unit.
In addition, the sensing unit 160 may be mounted (provided, formed) at one part of the vehicle. As an example, the sensing unit 160 may be mounted in the head lamp 155. In this case, the sensing unit 160 may be understood as one component included in the head lamp 155.
However, the present disclosure is not limited thereto, and the sensing unit 160 may be mounted to the outside of the head lamp 155.
The processor 170 may control the head lamp 155 to output (radiate) light of a preset color, based on the environment detected through the sensing unit 160 described above.
Specifically, the processor 170 may control the head lamp 155 to radiate light of a color corresponding to color information associated with the environment detected by the sensing unit 160 among a plurality of colors that may be output from the head lamp 155.
As an example, color information may be associated for each environment (condition) in the memory 140 included in the control device 100 of the present disclosure. At least one (or a plurality of) environment (condition) associated with the color information may be stored in the memory 140.
The processor 170 may output light of a preset color by outputting light of a color that corresponds to the color information associated with the environment (condition) detected through the sensing unit 160.
For example, when detected environments are different, and color information associated with the respective environments may also be different, and the processor 170 may control the head lamp 155 to irradiate lights of different colors based on the environment.
Specifically, if the environment detected through the sensing unit 160 corresponds to a first condition, then the processor 170 may control the head lamp 155 to output light of a first color associated with the first condition. In addition, if the environment detected through the sensing unit 160 corresponds to a second condition different from the first condition, the processor 170 may control the head lamp 155 to output light of a second color associated with the second condition.
The outputting of the light of the preset color according to the environment (or condition) will be described in more detail later with reference to
In some implementations, the head lamp 155 may include a plurality of light modules (or a plurality of light sources).
Each light module may be, for example, a unit lamp that may further include a light source, a reflector, a shield, a phosphor, a projection lens, and other additional components. One or more light sources may be provided in each light module.
The processor 170 may control a plurality of light modules (or a plurality of light sources) to output lights of different colors.
For example, the processor 170 may control the head lamp 155 such that a portion of the plurality of light modules (or light sources) irradiates light of a first color and such that another portion of the plurality of light modules (or light sources) irradiates light of a second color different from the first color.
An exemplary implementation in which the color of light is changed using a plurality of light modules or a plurality of light sources will be described in more detail later with reference to
Hereinafter, various structures of a head lamp (vehicle lamp) that may output light of at least one of a plurality of colors in the present disclosure will be described in more detail with reference to the accompanying drawings.
The head lamp 500 described herein, as shown in
The light module (or optical module) of the present disclosure may be applied to not only a projection type lamp but also a non-projection type lamp, e.g., a clear type lamp.
In the projection type to which a reflector is applied, the light module 510 may include a low beam light source 511, a high beam light source 512, a low beam reflector 513, a high beam reflector 514, a shield 515, a projection lens 516, and an outer lens 517.
A scenario in which the low beam light source 511 and the high beam light source 512 are respectively located in an upper direction and a lower direction with respect to a light axis Ax of the light module 510 will be described as an example. However, implementations of the present disclosure are not limited thereto, and the positions of the low beam light source 511 and the high beam light source 512 may be variously changed depending on usages or beam patterns of the light module 510.
The low beam reflector 513 is located in the light emission direction of the low beam light source 511, and the high beam reflector 514 is located in the light emission direction of the high beam light source 512.
The low beam reflector 513 is located over the low beam light source 511 and may have a reflective surface formed by depositing a material having high reflexibility, such as aluminum, on an inner surface thereof to reflect forward light generated upwardly from the low beam light source 511.
The low beam reflector 513 may be an elliptical reflector and may have two foci. One focus may correspond to an installation position of the low beam light source 511, and the other focus may be located adjacent to a cut-off edge of the shield 515 which will be described later. Hereinafter, the focus located to adjacent to the cut-off edge of the shield 515 is referred to as a first focus F1.
Because of optical characteristics of the elliptical reflector, the low beam reflector 513 condenses light emitted from the low beam light source 511 to the first focus F1.
The shield 515 may have an approximately plate shape, and may include a cut-off edge recessed backwardly at the front end thereof.
The light emitted from the low beam light source 511 is reflected by the low beam reflector 513 to be condensed to the first focus F1. A portion of the light condensed to the first focus F1 is blocked by the cut-off edge, and another portion of the light condensed to the first focus F1 is incident onto the projection lens 516 by passing through the first focus F1.
The light incident onto the projection lens 516 by passing through the first focus F1 has a low beam pattern in which a cut-off line is formed by the cut-off edge.
A base substrate of the low beam light source 511 is formed to have a flat surface, and light emitted from each light emitting element may be targeted by the low beam reflector 513.
The outer lens 517 divides the vehicle lamp into the interior and the exterior, and protects the inside of the vehicle lamp from foreign substances.
In the projection type to which any reflector is not applied, the light module 520 may include a light source 521, a shield 525, a projection lens 523, and an outer lens 524.
In this case, at least a portion of the light source 521 may form a low beam pattern, and the other portion of the light source 521 may form a high beam pattern. The low beam pattern may have a cut-off line formed by the shield 525.
A bezel may be disposed between the projection lens 523 and the light source 521. In some scenarios, the bezel may serve as a tunnel for light.
In a clear type lamp to which a reflector is applied, the light module 530 may include a low beam light source 531, a high beam light source 532, a low beam reflector 533, a high beam reflector 534, and an outer lens 535.
The low beam light source 531 is disposed to face upward with respect to a light axis of the light module 530, and light emitted from the low beam light source 531 is refracted in different directions by the low beam reflector 533 to form a low beam pattern.
The high beam light source 532 is disposed to face downward with respect to the light axis of the light module 530, and light emitted from the high beam light source 532 is refracted in different directions by the high beam reflector 534 to form a high beam pattern.
In the clear type lamp to which a reflector is not applied, the light module 540 may include a light source 541 and an outer lens 542. In this case, the light source 541 may be identified through the outer lens 542.
In a light module to which a reflector is applied, light is refracted by the reflector. Hence, a base substrate is formed to have a flat surface, and light emitting elements may have the same angle with respect to one direction.
In a light module to which any reflector is not applied, light output from a light source is directly emitted to form a distribution pattern. In this case, the light emitting elements (light sources) may have different angles with respect to one direction such that a predetermined distribution pattern is formed.
In this case, as shown in
When one light module is provided in a head lamp, the above-described light module may mean the head lamp (or vehicle lamp) itself.
Hereinafter, a structure for outputting at least one of a plurality of colors, which is applicable to at least one of the above-described light modules, will be described in more detail with reference to the accompanying drawings.
The head lamp (light module) of the present disclosure, as shown in the upper part of
The plurality of light sources may output lights of different colors. For example, as shown in the upper part of
At least one processor, for example, the processor 170, may control at least one of the plurality of light sources to output light of a preset color, based on a peripheral environment detected through the sensing unit 160.
The outputting of the light of the preset color may include a meaning of outputting light of a color corresponding to color information associated with the peripheral environment (condition) detected through the sensing unit 160.
Light output from the plurality of light sources may be refracted while passing through a lens to pass through a light tunnel. In the light tunnel, one light may be transmitted, and at least two lights may be mixed (interfered). As at least two lights output from the plurality of light sources that output lights of different colors are mixed (interfered), lights of various colors may be output.
For example, if the detected peripheral environment corresponds to a first condition, and red information is associated with the first condition, the processor 170 may control the head lamp 155 to output a light source R that outputs light of red among a plurality of light sources R, G, and B that output lights of different colors.
The head lamp (light module) of the present disclosure may further include a color filter formed to allow only light having a specific wavelength or light having a wavelength in a specific range to be transmitted therethrough.
Here, the color filter may be provided in plurality, and the plurality of color filters may allow light having different wavelengths or light having wavelengths in different ranges to be transmitted therethrough.
For example, as shown in the lower part of
The color filter described in this specification may be an RGB color filter. In addition, a plurality of color filters may be provided in the head lamp (light module).
When a color filter (RGB color filter) is provided in the head lamp (light module), at least one light source may be a light source that emits light of white.
At least one processor, for example the processor 170, may control the head lamp to output light of a preset color associated with a peripheral environment (condition) detected through the sensing unit 160, using the color filter.
For example, when light of red is to be output, the processor 170 may control the head lamp (light module) to output light of red by irradiating a light source formed to pass through the R filter among the plurality of light sources that output light of white.
However, the present disclosure is not limited thereto, and the processor 170 may control a color temperature of the light source provided in the head lamp. For example, the light source provided in the head lamp of the present disclosure may have a color temperature changed depending on a change in electrical signal. For example, the processor 170 may control the color temperature of the light source (or the color temperature of a light output from the light source) by adjusting a current applied to the light source.
Referring to
By controlling the color temperature of a light source, the processor 170 may control the color of light that is output from the light source. For example, as the color temperature increases, the light may have a color of blue. As the color temperature decreases, the light may have a color of red.
The processor 170 may output light of a preset color associated with a peripheral environment (condition) detected through the sensing unit 160 by controlling the color temperature of the light source provided in the head lamp. That is, the processor 170 may control the head lamp to output the light of the preset color by controlling (changing) the color temperature of the light source provided in the head lamp.
However, the present disclosure is not limited thereto, and the head lamp (light module) of the present disclosure may further include a color temperature conversion filter. In this case, the processor 170 may change the color temperature of the light source, using the color temperature conversion filter.
In addition, when the light source of the present disclosure is a laser light source, the color of light may be determined (changed) by controlling a fluorescent body.
Specifically, when the light source provided in the head lamp is a laser light source, the color of light may be changed by controlling a fluorescent body that changes the color of light emitted from the laser light source.
Hereinafter, for convenience of description, “that the processor 170 outputs light” and “that the head lamp is controlled such that the processor 170 outputs light” will be used together, and both should be understood as meanings identical or similar to each other.
In
The head lamp (light module) of the present disclosure may include various light sources such as a laser diode (LD), an organic light emitting diode (OLED), and a full color-light emitting diode (F-LED).
As shown in the upper part of
In some implementations, the head lamp (light module) may include only a blue laser light source. In this scenarios, as shown in the lower part of
When the light source of the present disclosure is the OLED, both a white OLED (WOLED) and an RGB OLED may be used.
For example, as shown in the upper part of
In addition, as shown in the lower part of
In some implementations, the F-LED may be provided with color filters to output lights of various colors.
The various light sources described in
That is, the present disclosure may provide a head lamp that may output light of at least one of a plurality of colors by combining the structures of the head lamp (light module), described in
Hereinafter, a method for controlling the control device 100 according to the exemplary implementation, which may include at least one of the above-described components, will be described in more detail with respect to the accompanying drawings.
Referring to
Specifically, the sensing unit 160 may detect a peripheral environment of the vehicle 700. The detecting of the peripheral environment may include a meaning that the sensing unit 160 receives (acquires, senses, extracts, detects, decides, or determines) information related to the peripheral environment of the vehicle.
For example, the sensing unit 160 may sense a kind of a road surface (road, ground) on which the vehicle 700 is located, a weather state, information related to a line indicated on the road surface (e.g., a color of the line, a kind of the line, etc.), a kind of a peripheral light source existing at the outside of the vehicle.
In addition, the sensing unit 160 may sense a situation in the vehicle 700. For example, the sensing unit 160 may sense a characteristic of a driver driving the vehicle (e.g., a demographic characteristic or physical characteristic of the driver) and whether a user input has been received (or whether a user request has been received).
That is, the detecting of the peripheral environment of the vehicle described in this specification may include a meaning of detecting not only an external environment (state, condition) of the vehicle 700 but also an internal environment (state, condition) of the vehicle 700.
An operation of detecting the peripheral environment of the vehicle may be performed by combining one or two or more of various sensors described above, such as a camera included in the sensing unit 160, a laser sensor, a radar, a lidar, and an ultrasonic sensor.
The sensing unit 160 of the present disclosure, as described above, may be the sensing unit 760 provided in the vehicle or may be a separate sensing unit.
After that, in the present disclosure, the head lamp is controlled to output light of a preset color, based on the detected peripheral environment (S820).
Specifically, the processor 170 may control the head lamp 155 to irradiate light of a color corresponding to color information associated with the peripheral environment detected through the sensing unit 160 among a plurality of colors that may be output from the head lamp 155.
As an example, color information may be associated for each peripheral environment (condition) in the memory 140 included in the control device 100 of the present disclosure. At least one (or a plurality of) peripheral environment (condition) associated with the color information may be stored in the memory 140.
That the processor 170 outputs light of a preset color may include a meaning of outputting light of a color corresponding to the color information associated with the peripheral environment (condition) detected through the sensing unit 160.
In this specification, for convenience of illustration, “light of a color corresponding to the color information associated with the peripheral environment (condition)” will be described as light of a color associated with the peripheral environment.
For example, when detected peripheral environments are different, and color information associated with the respective peripheral environments are different, the processor 170 may control the head lamp 155 to irradiate lights of different colors.
Here, the head lamp 155 may include at least one of a plurality of light sources that output lights of different colors and a color filter formed to allow only light having a specific wavelength or light having a wavelength in a specific range to be transmitted therethrough.
In the step (S820) of controlling the head lamp, the processor 170 may output the light of the preset color associated with the peripheral environment (condition), using at least one of the plurality of light sources and the color filter, which are provided in the head lamp.
Also, in the step (S820) of controlling the head lamp, the processor 170 may output the light of the preset color associated with the peripheral environment (condition) by controlling the color temperature of a light source provided in the head lamp.
The processor 170 may output the light of the preset color by emitting at least one of the plurality of light sources that output lights of different colors.
Also, the processor 170 may output the light of the preset color by emitting a light source formed to pass through a color filter that allows only the light of the preset light to be transmitted therethrough, among a plurality of light sources that output light of white.
Also, the processor 170 may change a color temperature by changing an electrical signal applied to at least one of an RGB light source or white light source. The processor 170 may output the light of the preset color through the change in electrical signal.
Also, the processor 170 may output the light of the preset color, using a color temperature conversion filter provided in the head lamp 155 (light module).
In the step (S820) of controlling the head lamp, if the peripheral environment detected through the sensing unit 160 corresponds to a first condition, the processor 170 may control the head lamp 155 to output light of a first color associated with the first condition. Also, if the detected peripheral environment corresponds to a second condition different from the first condition, the processor 170 may control the head lamp 155 to output light of a second color associated with the second condition.
Here, the first color and the second color may be colors different from each other. For example, when color information associated with the first condition and color information associated with the second condition are different from each other, the first color and the second color may be colors different from each other.
As another example, when the color information associated with the first condition and the color information associated with the second condition are the same even though the first condition and the second condition are different from each other, the first color and the second color are the same color.
The processor 170 may control the head lamp 155 to output the light of the first color or the light of the second color by using at least one of the plurality of light sources and the color filter, which are provided in the head lamp, or by controlling the color temperature of the light source.
Hereinafter, various exemplary implementations of outputting lights of different colors according to peripheral environments (conditions) of the vehicle will be described in more detail with reference to the accompanying drawings.
Referring to
The processor 170 may output lights of different colors, based on a kind of a road surface onto which light is irradiated, which is detected through the sensing unit 160.
Specifically, if the kind of the road surface is detected as a first kind, the processor 170 may control the head lamp 155 to output light of a first color associated with the first kind.
In addition, if the kind of the road surface is detected as a second kind different from the first kind, the processor 170 may control the head lamp 155 to output light of a second color associated with the second kind.
For example, referring to
In addition, when the detected kind of the road surface is a cement road, the processor 170 may control the head lamp 155 to output light of a second color different from the first color (e.g., light based on white).
In addition, when the kind of the road surface, which is detected through the sensing unit 160, is an asphalt road, the processor 170 may control the head lamp 155 to output light of a third color different from the first color and the second color (e.g., light based on blue).
Hereinafter, description will be given of configurations in which different color information are associated for different conditions. However, it should be noted that, when the same color information is associated for different conditions, a case where light of the same color is output even when conditions are different may be implemented.
Referring to
The processor 170 may detect a weather state through the sensing unit 160. The technique of detecting a weather state through the sensing unit 160 is a general technique, and therefore, a detailed description will be omitted.
The processor 170 may determine a color of light output from the head lamp 155, based on the detected weather state.
For example, referring to
The processor 170 may determine a color of light output from the head lamp 155 according to the weather state, based on the color information associated for every condition.
After that, the processor 170 may control the head lamp 155 to output light of the determined color.
Referring to
The processor 170 may detect a color of a line detected on a road surface on which the vehicle 700 travels through the sensing unit 160.
After that, the processor 170 may control the head lamp 155 to output lights of different colors, based on the color of the line detect on the road surface on which the vehicle 700 travels.
For example, referring to
In addition, if the color of the line detected on the road surface on which the vehicle 700 travels is white, the controller 170 may control the head lamp 155 to output light of a second color (e.g., light based on white).
In addition, if the color of the line detected on the road surface on which the vehicle 700 travels is blue, the controller 170 may control the head lamp 155 to output light of a third color (e.g., light based on blue).
As an example, the controller 170 may control the head lamp 155 to output light of a color corresponding to the color of the detected line.
In this case, the controller 170 may control the head lamp 155 to output light of a color corresponding to the color of the line, using a plurality of light sources that output lights of different colors and a color filter, which are provided in the head lamp 155 (light module). Also, the processor 170 may control the head lamp 155 to output light of a color corresponding to the color of the line by controlling the color temperature of a light source provided in the head lamp 155 (light module).
In some implementations, a plurality of light modules may be provided (included) in the head lamp 155. Here, the light module may be a light module described in
For example, as shown in
A plurality of light modules 1210, 1220, 1230, and 1240 may be provided in the left head lamp 155L and the right head lamp 155R.
Hereinafter, for convenience of illustration, the plurality of light modules will be described as a first light module 1210, a second light module 1220, a third light module 1230, and a fourth light module 1240.
Referring to
For example, the first light module 1210 may irradiate light onto a first region 1211, and the second light module 1220 may irradiate light onto a second region 1221. In addition, the third light module 1230 may irradiate light onto a third region 1231, and the fourth light module 1240 may irradiate light onto a fourth region 1241.
The processor 170 may detect conditions (peripheral environments) in the first to fourth regions, using the sensing unit 160.
If different conditions are detected from the regions 1211, 1221, 1231, and 1241, the processor 170 may control the head lamp 155 such that the plurality of light modules 1210, 1220, 1230, and 1240 output lights of different colors.
The processor 170 may determine, in various manners, a condition detected in each region. For example, a plurality of conditions may be detected in any one region among the plurality of regions (first to fourth regions).
In this case, the processor 170 may determine a condition detected in the corresponding region, based on a priority order provided to each condition.
As another example, the processor 170 may determine a condition in which an area satisfying a corresponding condition among a plurality of conditions detected in any one region is widest as a condition detected in the corresponding region.
In addition, when a plurality of conditions are detected in any one region, a method for setting any one condition may be variously designed/changed by a setting of a user or control of the processor.
If different conditions are detected (determined) in the regions 1211, 1221, 1231, and 1241 in this manner, the processor 170 may control the head lamp 155 such that the plurality of light modules output lights of different colors.
Specifically, if a first condition is detected in the first region 1211 among the regions, the processor 170 may control the light module 1210 irradiating light onto the first region 1211 among the plurality of light modules to output light of a first color associated with the first condition.
In addition, if a second condition different from the first condition is detected in the second region 1221 different from the first region 1211 among the regions, the processor 170 may control the light module 1220 irradiating light onto the second region 1221 among the plurality of light modules to output light of a second color associated with the second condition.
For example, referring to
In addition, when the second condition detected (determined) in the second region 1221 onto which the second light module 1220 irradiates light is determined as a white line, the processor 170 may control the second light module 1220 to irradiate the light of the second color (e.g., light based on white) associated with the second condition.
In the case of the third and fourth light modules 1230 and 1240, a color of light may be determined by the above-described method, and the light of the determined color may be output.
In
For example, at least a portion of the first region onto which the first light module irradiates light may overlap with the second region onto which the second light module irradiates light.
In addition, at least a portion of the second region onto which the second light module irradiates light may overlap with the first and third regions onto which the first and third light modules irradiate light.
When at least portions of a plurality of regions onto which a plurality of light modules irradiate light overlap with each other, the processor 170 may irradiate light in a gradation form through brightness or selective on/off of the plurality of light modules.
In
In some implementations, a plurality of light source (light emitting elements) may be included in each of the plurality of light module (or the head lamp 155). As an example, the plurality of light sources may be matrix light sources formed in a matrix form or micro light sources having a size of a micro unit. In addition, the plurality of light sources may be micro matrix light sources in which a plurality of light sources having a size of a micro unit are formed in a matrix form.
The processor 170 may individually control the plurality of light sources. The processor 170 may selectively turn on/off the plurality of light sources, or may selectively change a color.
Referring to
For example, a plurality of conditions may be detected in the region 1300 onto which light is irradiated from the head lamp 155. Here, the plurality of conditions may be different from one another.
In addition, color information associated with the plurality of conditions may be different from one another.
In this case, the processor 170 may determine a color of light to be irradiated by each of the plurality of light sources by individually controlling the plurality of light sources provided in the head lamp 155.
For example, the processor 170 may control a first light source(s) that irradiates light onto a region 1300a in which a first condition is detected among the plurality of light sources to output light of a color associated with the first condition.
In addition, the processor 170 may control a second light source(s) that irradiates light onto a region 1300b in which a second condition is detected among the plurality of light sources to output light of a color associated with the second condition.
As an example, when a kind of a lane (first condition) and a color of a line (second condition) are detected in a region onto which light is irradiated, and colors associated with the kind of lane and the color of the line are different from each other, the processor 170 may irradiate light of a first color associated with the first condition onto a lane 1300d, and irradiate light of a second color associated with the second color onto a line 1300e.
Here, when color information associated with the first condition and the color information associated with the second condition are different from each other, the first color and the second color may be different from each other.
The present disclosure may provide a method for controlling the head lamp, in which, for conditions respectively detected in regions onto which light is irradiated from the head lamp through individual control (individual color change) of a plurality of light sources, light of an optimized color may be irradiated for each region in which each condition is detected.
In addition, the present disclosure may change a color of light depending on a kind of a peripheral light source.
Referring to
For example, the sensing unit 160 may detect a kind of a light source existing around the vehicle, based on detection of infrared light, generation of a flicker signal, and the like. If the infrared light is detected and the flicker signal is generated, the sensing unit 160 (or the processor 170) may determine (decide, sense, detect) the kind of the light source as a light bulb (incandescent lamp). If the infrared light is detected and the flicker signal is not generated, the sensing unit 160 (or the processor 170) may determine (decide, sense, detect) the kind of the light source as the sun (or moon). If the infrared light is not detected and the flicker signal is generated, the sensing unit 160 (or the processor 170) may determine (decide, sense, detect) the kind of the light source as a fluorescent lamp.
As another example, the sensing unit 160 (or the processor 170) may detect a color of the peripheral light source and determine a kind of the peripheral light source, based on the detected result.
As another example, the sensing unit 160 (or the processor 170) may detect at least one of the frequency, wavelength, and electrical energy of light received from the peripheral light source, and determine a kind of the peripheral light source, based on the detected result.
As another example, the sensing unit 160 (or the processor 170) may determine a kind of a peripheral light source, based on at least one of the electric field and magnetic field of light received from the peripheral light source.
The technique of determining a kind of the peripheral light source is a general technique, and therefore, a detailed description will be omitted.
The processor 170 may determine a color of light output from the head lamp 155, based on the detected kind of the light source.
As an example, as shown in
As another example, if the kind of the light source, detected through the sensing unit 160, is a second kind different from the first kind, the processor 170 may control the head lamp 155 to output light of a second color associated with the second kind.
When color information associated with the first kind and color information associated with the second kind are different from each other, the first color and the second color may be colors different from each other.
In addition, the processor 170 may control the head lamp 155 to output lights of different colors, based on a brightness around the vehicle, detected through the sensing unit 160.
For example, if the brightness around the vehicle is a first brightness, the processor 170 may control the head lamp 155 to output light of a first color associated with (corresponding to) the first brightness. If the brightness around the vehicle is a second brightness, the processor 170 may control the head lamp 155 to output light of a second color associated with the second brightness.
In addition, the present disclosure may change a color of light irradiated from the head lamp according to a user request.
The processor 170 may change a color of light, based on a user request.
Here, the user request may include a user input received through the input unit, the output unit, or the display device, which is provided in the vehicle.
Referring to the lower part of
If a user input is received through the menu screen, the processor 170 may control the head lamp 155 to output light of a color corresponding to the received user input.
In some implementations, a menu (e.g., a color spectrum) configured to set a color may be output on the display unit or the display device. After that, the processor 170 may determine a color of light to be output by the head lamp through the output menu.
The present disclosure is not limited thereto, and the sensing unit 160 of the present disclosure may detect a characteristics of a driver of the vehicle (e.g., demographic or physical information of the driver). For example, the sensing unit 160 may detect physical information of a driver, based on an image received through a camera provided inside the vehicle.
After that, the processor 170 may control the head lamp 155 to output light of a color associated with the detected demographic or physical characteristic of the driver.
As an example, as shown in
As another example, the processor 170 may recognize an iris of the driver's eyes, based on the image received through the camera, and determine (decide, extract, sense, detect) a color of the driver's iris. After that, the processor 170 may control the head lamp to output lights of different colors, based on the determined color of the iris. For example, the processor 170 may control the head lamp to output light of a color (e.g., a complementary color) contrary to the color of the iris.
Color information associated with each condition (or a color of light output for each condition) may be determined by a user setting, may be provided in the vehicle or the control device from when a product is released, may be received from an external device, or may be determined under control of the controller (or the processor).
In the above, that the processor 170 irradiates light may mean that the processor 170 controls the head lamp 155 to irradiate light.
In addition, a change in color of light output from the head lamp may be performed through a combination of at least one or two or more among a plurality of light sources outputting different colors, a light tunnel, a phosphor, a color filter, a color temperature conversion filter, and color temperature control of the light source.
The control device 100 described above may be included in the vehicle 700.
In addition, the operation or control method of the control device 100 described above may be identically/similarly analogized and applied as that of the vehicle 700.
For example, the control method of the vehicle (or the control method of the control device) may include a step of detecting a peripheral environment of the vehicle and a step of controlling the head lamp to output light of a preset color, based on the detected peripheral environment.
In addition, the head lamp may include at least one of a plurality of light sources outputting different colors and a color filter formed to allow only light having a specific wavelength or light having a wavelength in a specific range to be transmitted therethrough.
In the step of controlling the head lamp, at least one of the plurality of light sources and the color filter, provided in the head lamp, may be used based on the detected peripheral environment, or the light of the preset color may be output by controlling the color temperature of a light source provided in the head lamp.
Also, in the step of controlling the head lamp, if the detected peripheral environment corresponds to a first condition, the head lamp may be controlled to output light of a first color associated with the first condition. If the detected peripheral environment corresponds to a second condition different from the first condition, the head lamp may be controlled to output light of a second color associated with the second condition.
The present disclosure has advantages as follows.
First, the present disclosure may provide a control device and a vehicle having the same, which may output light of a color optimized based on a peripheral environment detected around the vehicle.
Second, the present disclosure may provide a head lamp configured to output lights of various colors.
Third, the present disclosure may provide a new user interface which may remarkably improve visibility of a driver by outputting light of a color associated with a detected peripheral environment (condition).
Advantages of the present disclosure are not limited to the aforementioned advantages, and those skilled in the art may evidently understand other advantages that have not been mentioned above from the description of the appended claims.
The above-described steps and all functions/operations described in this specification may be performed by not only the control device 100 but also the controller 770 provided in the vehicle 700.
In addition, all functions, configurations, or control methods, which the control device 100 performs, may be performed by the controller 770 provided in the vehicle 700. That is, all control methods described in this specification may be applied a control method of the vehicle, and may be applied a control method of the control device.
The foregoing implementations may be implemented as codes readable by a computer on a medium written by the program. The computer-readable media may include various types of recording devices in which data readable by a computer system is stored. Examples of the computer-readable media may include hard disk drive (HDD), solid state disk (SSD), silicon disk drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage device, and the like, and also include a device implemented in the form of a carrier wave (for example, transmission via the Internet). In addition, the computer may include the processor 170 of the control device 100 or the controller 770 of the vehicle. Accordingly, the detailed description thereof should not be construed as restrictive in all aspects but considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims and all changes that come within the equivalent scope of the invention are included in the scope of the invention.
