As shown in
The LED lamp plate 20 is provided at an opening position of the sector-shaped shell 10, and the motor component 30 is embedded at a center position of the sector-shaped shell 10. The light reflecting component 40 is divided into a circular part 41 and a long plate part 42, the circular part 41 is connected to a center position of the motor component 30, and the length of the long plate part 42 is the same as a radius length of the sector-shaped shell 10. The microprocessor 70 is arranged in the lamp holder device.
The microprocessor 70 determines a rotation angle of the motor component 30 based on the camera shooting component 50 and the infrared light compensating component 60 through the eye tracking technology, and controls the motor component 30 to rotate to drive the light reflecting component 40 to rotate so as to change the angle of light emission.
Specifically, an angular radian of the sector-shaped shell 10 can be any angle within the range of greater than 270 degrees and less than 320 degrees.
Specifically, the camera shooting component 50 can be a component with a camera shooting function, the camera shooting component 50 can be a camera or a CCD camera, and the camera shooting component 50 can receive infrared lights reflected by the human eyes and capture an eye image. The infrared light compensating component 60 can be a component that emits infrared light, and for example, the infrared light compensating component 60 can be an infrared light emitting diode.
In this embodiment, there are various arrangement positions for arranging the camera shooting component 50 and the infrared light compensating component 60 on the lamp holder device, in one of the arrangement positions as shown in
Specifically, in a case where the camera shooting component 50 and the infrared light compensating component 60 are arranged inside the lamp holder device, since the material of the sector-shaped shell 10 can transmit infrared light, infrared light emitted by the infrared light compensating component 60 can be transmitted to a user's eye through the sector-shaped lamp shell 10, and infrared light reflected by the user's eye, after passing through the sector-shaped lamp shell 10, is focused by the camera shooting component 50 to form an eye image. In a case where the camera shooting component 50 and the infrared light compensating component 60 are arranged on the front side of the outer surface of the sector-shaped shell 10, infrared light emitted by the infrared light compensating component 60 can be directly emitted to a user's eye, and infrared light reflected by the user's eye is directly focused by the camera shooting component 50 to form an eye image.
In this embodiment, the camera shooting component 50 and the infrared light compensating component 60 are controlled by the microprocessor 70. The camera shooting component 50 and the infrared light compensating component 60 can receive instructions from the microprocessor 70 and perform operations corresponding to the instructions. The camera shooting component 50 can further send a collected eye image to the microprocessor 70. Specifically, the microprocessor 70 can be an operational chip or a microcontroller.
Specifically, the microprocessor 70 can use the eye tracking technology to determine the direction in which the user is gazing, the eye tracking technology is a technology that uses infrared light and a camera to detect a gazing direction of human eyes. After determining the direction in which the user is gazing, the microprocessor 70 can calculate the adjustment angle of the light.
In this embodiment, the microprocessor 70 can adjust a lighting angle of lamplight by controlling the motor component 30 to rotate. Specifically, the rotation of the motor component 30 can drive the light reflecting component 40 to rotate. The light reflecting component 40 can rotate clockwise or counterclockwise within a sector-shaped notch of the sector-shaped shell 10 to change the region of light emission. Specifically, the region of light emission is the region formed between the light reflecting component 40 and the LED lamp plate 20, and changing the size of this region can cause a change in the angle of light emission.
In this embodiment, the lamp holder device is internally provided with a power supply or is provided with a plug-in interface.
Specifically, the lamp holder device can be supplied power in two methods. In a first method: the lamp holder device is internally provided with a power supply for supplying power to its internal components, and in the case where the lamp holder device is internally provided with a power supply, the lamp holder device can be movably used without requiring other devices to supply power to the lamp holder device. In a second method, the lamp holder device is provided with a plug-in interface, and other power source is connected to the lamp holder device through the plug-in interface for supplying power to the lamp holder device, and in the case where the lamp holder device is provided with a plug-in interface, the lamp holder device is required to be fixed to a power supply interface for use.
In the lamp holder device according to the first embodiment of the present disclosure, the microprocessor determines the rotation angle of the motor component based on the camera shooting component and the infrared light compensating component through the eye tracking technology, and controls the motor component to rotate, to drive the light reflecting component to rotate so as to change the angle of light emission. The above lamp holder device can automatically change the lighting region according to the user's gaze direction by controlling the motor component to rotate, to drive the light reflecting component to rotate so as to change the angle of light emission, which can effectively improve the effect of spotlight angle adjustment.
Furthermore, the microprocessor 70 is configured to control the infrared light compensating component 60 to emit infrared light toward a user's eyes, and to control the camera shooting component 50 to capture an eye image of the user, and determine a direction in which the user's eyes are gazing based on the eye image, and determine the rotation angle of the motor component based on the direction.
Specifically, the infrared light compensating component 60 can emit infrared light to a user's eyes after receiving an instruction from the microprocessor 70. When the infrared light shines on the user's eye, a reflection image is formed on a corneal surface of the eye, and the reflection image is called a Purkinje spot. The camera shooting component 50 can collect an eye image after receiving an instruction from the microprocessor 70. Assuming that the user's head remains stationary, as the position of the infrared light compensating component 60 is fixed and the eyeball is an approximate sphere, when the eyeball rotates, it can be considered that the absolute position of the Purkinje spot remains unchanged, and the positions of the iris and pupil are changed correspondingly. In this way, the direction of sightline can be determined based on the relative position relationship between the Purkinje spot formed on the iris by the infrared light and the pupil. Since the grayscale value of the pupil is a minimum and the grayscale value of the Purkinje spot is a maximum, it is easy to find the relative position relationship between the pupil and the Purkinje spot after performing a threshold processing on the eye image, thereby determining the direction in which the user's eyes are gazing.
Specifically, after the direction in which the user's eyes are gazing is determined, an adjustment angle of light can be determined based on a current lighting angle of light, and the adjustment angle of light can be used as the rotation angle of the motor component 30.
In one embodiment, the microprocessor 70 is further configured to control the power supply to supply power to the LED lamp plate to turn on the light when it is detected by the microprocessor 70 that the user is gazing at a preset region and a gazing duration of the user is longer than a preset duration; and control the power supply to power off the LED lamp plate to turn off the light when it is detected by the microprocessor 70 that the user's eyes are not gazing at the preset region.
In this embodiment, the lamp holder device can further automatically detect, through the microprocessor 70, whether the user has gaze behavior, and automatically turn on or turn off the lamp based on the detection results.
Specifically, the preset region can be a region pre-set by the user or developer, and the preset region can be set according to the position at which the lamp holder device is disposed, for example, if the lamp holder device is placed above the computer screen, the preset region can be the computer screen and a desktop region where the screen is located, and if the lamp holder device is placed on the desktop, the preset region can be a desktop region. The preset duration can be pre-set by the user or developer, for example, the preset duration can be three seconds, which can be understood as indicating that the user has gaze behavior and needs to turn on the light when the user's gaze at the preset region is detected to be greater than or equal to three seconds.
An example scenario is that: a computer screen is placed on the desktop, and the lamp holder device is placed above the computer screen. If it is detected that the user is gazing at the desktop below the computer screen for three seconds or more, the light can be automatically turned on and directed towards the desktop. If it is detected that the user is gazing at the desktop below the computer screen for not more than 3 seconds, the light is not required to be turned on, and if the light is in an on state at this time, the light can be turned off.
As shown in
In this embodiment, the microprocessor 70 is configured to control the motor shaft 31 to rotate. When the motor shaft 31 rotates, the motor body 32 drives the light reflecting component 40 to move, and the angle of light emission is controlled by the movement of the light reflecting component 40.
Specifically, a rotating member of the motor component 30 is the motor shaft 31. The rotation of the motor shaft 31 causes the motor body 32 to rotate. The rotation of the motor body 32 can drive the light reflecting component 40 to rotate, and the rotation of the light reflecting component 40 can change the size of an included angle formed between the light reflecting component 40 and a plane in which the LED lamp plate 20 is located, thereby changing the angle of light emission.
The lamp holder device according to the second embodiment of the present disclosure specifies the structure of the motor component 30. In the lamp holder device, the angle at which the light reflecting component reflects light is adjusted by rotating the motor shaft 31, which can achieve better effect of spotlight angle adjustment.
A lamp is provided according to a third embodiment of the present disclosure, which includes a lamp holder device according to the first embodiment and the second embodiment of the present disclosure, and further includes a lamp base connected to the lamp holder.
The lamp according to the third embodiment of the present disclosure can be a screen hanging lamp or a desk lamp, which is not specifically limited here.
Specifically, the screen hanging lamp can be hung above the screen for use. The screen hanging lamp, through its unique light directing design, directs the light path towards the desktop below the screen, rather than hitting the screen. Its obvious advantage is that when you need to see the monitor, the qualities of color and image on the screen are not affected by the hanging lamp at all. When eyesight leaves the monitor and two eyes look towards the keyboard or desktop workspace, the screen hanging lamp can provide sufficient brightness.
Specifically, the lamp formed by connecting the lamp holder device to the lamp base can be suitable for various scenarios. The above-mentioned lamp has the functions of the lamp holder device according to any embodiment of the present disclosure, and has the beneficial effects corresponding to the lamp holder device.
This embodiment of the present disclosure provides a specific implementation based on the technical solutions of the embodiments described above.

Specifically, after receiving an instruction sent by the microprocessor, the infrared light compensating component can emit infrared light to a position of the user's eye based on the instruction, and infrared light reflected by the user's eye is focused by the camera shooting component to form an eye image.
In S120, a position where the user's eyes are gazing is determined based on the eye image.
Specifically, when the infrared light shines on the user's eye, a reflection image is formed on a corneal surface of the eye, and the reflection image is called a Purkinje spot. The camera shooting component can collect an eye image after receiving an instruction from the microprocessor. Assuming that the user's head remains stationary, as the position of the infrared light compensating component is fixed and the eyeball is an approximate sphere, when the eyeball rotates, it can be considered that the absolute position of the Purkinje spot remains unchanged, and the positions of the iris and pupil are changed correspondingly. In this way, the direction of sightline can be determined based on the relative position relationship between the Purkinje spot formed on the iris by the infrared light and the pupil. Since the grayscale value of the pupil is a minimum and the grayscale value of the Purkinje spot is a maximum, it is easy to find the relative position relationship between the pupil and the Purkinje spot after performing a threshold processing on the eye image, thereby determining the direction in which the user's eyes are gazing.
In S130, the motor component is controlled to rotate to drive the light reflecting component to move, and an angle of light emission is controlled through the movement of the light reflecting component.
Specifically, the microprocessor can adjust the lighting angle of lamplight by controlling the rotation of the motor component. Specifically, the rotation of the motor component can drive the light reflecting component to rotate, and the light reflecting component can rotate clockwise or counterclockwise within a sector-shaped notch of the sector-shaped shell 10 to change the region of light emission.
Specifically, a rotating component of the motor component is the motor shaft, the rotation of the motor shaft causes the motor body to rotate. The rotation of the motor body can drive the light reflecting component to rotate, and the rotation of the light reflecting component can change the size of an included angle formed between the light reflecting component and a plane where the LED lamp plate is located, thereby changing the angle of light emission.
In the lighting control method according to the fourth embodiment of the present disclosure, first, the infrared light compensating component is controlled to emit infrared light to the user's eyes, and then the camera shooting component is controlled to collect the user's eye image; then, the position where the user's eyes are gazing is determined based on the eye image; and finally, the motor component is controlled to rotate, to allow the motor component to drive the light reflecting component to move when the motor component rotates, and the angle of light emission is controlled through the movement of the light reflecting component. With the above method, the lighting region can be automatically changed according to the user's gaze direction by controlling the motor component to rotate, to drive the light reflecting component to rotate so as to change the angle of light emission, which can effectively improve the effect of spotlight angle adjustment.
Furthermore, the method further includes as follow. Whether the user is gazing at a preset region is determined based on the position where the user's eyes are gazing; if it is determined that the user is gazing at a preset region and a gazing duration is longer than or equal to a preset duration, the power supply is controlled to supply power to the LED lamp plate to turn on the light; and if it is determined that the user is not gazing at the preset region, the power supply is controlled to power off the LED lamp plate to turn off the light.
In this embodiment, the lamp holder device can also automatically detect, through the microprocessor 70, whether the user has gaze behavior, and automatically turn on or turn off the lamp based on the detection results.
Specifically, the preset region can be a region pre-set by the user or developer, and the preset region can be set according to the position at which the lamp holder device is disposed, for example, if the lamp holder device is placed above the computer screen, the preset region can be the computer screen and a desktop region where the screen is located, and if the lamp holder device is placed on the desktop, the preset region can be a desktop region. The preset duration can be pre-set by the user or developer, for example, the preset duration can be three seconds, which can be understood as indicating that the user has gaze behavior and needs to turn on the light when the user's gaze at the preset region is detected to be greater than or equal to three seconds.
