BACKGROUND OF THE PRESENT DISCLOSURE

Field of the Present Disclosure

The present disclosure relates to a vehicle field, and more particularly to, a mood lamp with dynamic effect and a vehicle provided with the mood lamp.

Description of Related Art

Mood lamps currently adjust light emission by use of a light string or a light guide in an indirect or direct lighting method, in which covers use a light transmitting material, and surfaces are laser engraved and implement a lighting effect with a specific pattern. However, a problem present in the mood lamp is that the existing structure may not be used when the mood lamp emits light on a specific plane or curved surface and produces various rhythm effects. Furthermore, when a chrome should be plated on the surface, the light emission of the existing structure was weak.

Therefore, the existing mood lamp needs further improvement.

The information included in this Background of the present disclosure is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

BRIEF SUMMARY

Various aspects of the present disclosure are directed to providing a mood lamp with dynamic effect and a vehicle provided with the mood lamp. According to a mood lamp with a dynamic effect, when power of a light source is turned on, light of the light source is reflected by a light reflection film and then passes through a light guide plate and a cover, implementing light emission. Because the light source is close to a first side of the light guide plate and far away from a second side of the light guide plate, the mood lamp may emit light so that brightness is gradually changed. When the power of the light source is turned off, the mood lamp becomes a decoration panel with a metallic decoration effect of a wave pattern, improving a layered feeling and luxury feeling of a vehicle interior material.

Various aspects of the present disclosure are directed to providing a mood lamp with a dynamic effect. The mood lamp may include: a bracket configured to be mounted on a vehicle body; a cover provided on the bracket and used to form an appearance of the mood lamp; a light guide plate provided in an accommodation space formed by the cover and the bracket, adjacent to the cover, and including a surface close to the cover and including an uneven wave pattern, wherein a metal plating layer is provided on the surface including the wave pattern; a light source provided in the accommodation space to be close to a first side of the light guide plate and far away from a second side of the light guide plate; and a light reflection film provided in the accommodation space and reflecting a light emitted by the light source to a surface of the light guide plate far away from the cover, wherein the reflected light sequentially passes through the light guide plate and the cover, and is then emitted to an outside of the cover.

The cover may be made of a PC material, and an external surface may be a flat surface.

The external surface of the cover may have a leather pattern to form a translucent matte effect.

The surface of the light guide plate including the wave pattern may form the metal plating layer through vacuum aluminum plating or vacuum chrome plating.

An edge portion of the cover may be provided on an interior material of a vehicle to form an exposed portion and an insertion portion, an area of the light guide plate may be greater than an area of the exposed portion, and an inclined transition portion may be formed at a position of the light guide plate corresponding to the insertion portion.

The light source may be supported by an upper wall or a lower wall of the bracket, and the light source may be positioned outside a range covered by the exposed portion.

The light source may include a light source board and one or more LEDs provided on the light source board, and the light source board may be electrically connected to a driving circuit board for controlling the one or more LEDs through a plug assembly.

The light source board may include two or more sub boards, and the respective sub boards may be electrically connected to each other through a plug assembly.

The light-emitting diode (LED) may be a smart LED, and the driving circuit board may include a controller.

A light film may have a flat surface inclined to have a constant angle between the flat surface and the light guide plate so that the light emitted from the light source is directed toward the light guide plate.

The power of each of the LEDs may be 0.1 W to 1 W, and a distance between the respective LEDs is 20 mm to 40 mm.

Various aspects of the present disclosure are directed to providing a vehicle provided with the mood lamp with the dynamic effect according to the one aspect of the present disclosure.

According to an exemplary embodiment of the present disclosure, when power of a light source is turned on, light of the light source is reflected by a light reflection film and then passes through a light guide plate and a cover, implementing light emission. Because the light source is close to a first side of the light guide plate and far away from a second side of the light guide plate, the mood lamp may emit light so that brightness is gradually changed. When the power of the light source is turned off, the mood lamp becomes a decoration panel with a wavy metal decoration effect, improving a layered feeling and luxury feeling of a vehicle interior material. Furthermore, the mood lamp has the metal decoration effect but does not require a laser engraving process, reducing the cost of a laser engraving process.

The method and apparatus of the present disclosure have other characteristics and advantages. Such characteristics and advantages will become apparent from the accompanying drawings and the exemplary embodiment to be described below or will be described in detail in the accompanying drawings and the exemplary embodiment to be described below. Both the drawings and the exemplary embodiment are intended to interpret certain principles of the present disclosure.

The methods and apparatuses of the present disclosure have other features and advantages which will be apparent from or are set forth in more detail in the accompanying drawings, which are incorporated herein, and the following Detailed Description, which together serve to explain certain principles of the present disclosure.

DETAILED DESCRIPTION

Hereinafter, these embodiments will be exemplified in the drawings and will be described later with reference to various exemplary embodiments of the present disclosure in detail. While the present disclosure has been described in conjunction with exemplary embodiments of the present disclosure, it should be understood that the present specification is not intended to limit the present disclosure to these exemplary embodiments of the present disclosure. To the contrary, the present disclosure not only includes these exemplary embodiments of the present disclosure, but also includes various alternatives, modifications, equivalents, and other embodiments within the scope of the spirit of the present disclosure and the scope of the appended claims.

Hereinafter, a mood lamp with a dynamic effect according to various exemplary embodiments of the present disclosure will be described by combining FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, and FIG. 8.

As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, and FIG. 8, a mood lamp with a dynamic effect according to various exemplary embodiments of the present disclosure includes a bracket 1, a cover 2, a light guide plate 3, a light source 4, and a light reflection film 5.

The bracket 1 is mounted on a vehicle body.

The cover 2 is provided on the bracket 1 and is used to form an appearance of the mood lamp.

The light guide plate 3 is provided in an accommodation space 11 formed by the cover 2 and the bracket 1 (see FIG. 5 and FIG. 6), and is adjacent to the cover 2. A surface of the light guide plate 3 close to the cover 2 has an uneven wave pattern, and a metal plating layer 32 is provided on the surface including the wave pattern (see FIG. 4).

The light source 4 is provided in the accommodation space 11 to be close to one side of the light guide plate 3 and far away from the other side of the light guide plate 3 (that is, the light source 4 in FIG. 5 and FIG. 6 is closer to an upper side of the light guide plate 3 and far away from a lower side of the light guide plate 3).

The light reflection film 5 is provided in the accommodation space 11, and reflects light emitted by the light source 4 to a surface far away from the cover 2 of the light guide plate 3.

Additionally, the reflected light sequentially passes through the light guide plate 3 and the cover 2, and then is emitted to an outside of the cover 2.

When power of the light source 4 is turned on, the light of the light source 4 may be reflected by the light reflection film 5 and then pass through the light guide plate 3 and the cover 2 to emit light. Because the light source 4 is close to one side of the light guide plate 3 and far away from the other side of the light guide plate 3 (that is, in FIG. 5 and FIG. 6, because the light source 4 is close to the upper side of the light guide plate 3, and is far away from the lower side of the light guide plate 3), the mood lamp may emit the light so that brightness is gradually changed.

When the power of the light source 4 is turned off, because the surface of the light guide plate 3 close to the cover 2 has an uneven wave pattern and the metal plating layer 32 is provided on the surface including the wave pattern (see FIG. 4), the mood lamp becomes a decoration panel with a metallic decoration effect of a wave pattern, improving a layered feeling and luxury feeling of an interior material of a vehicle. Furthermore, the mood lamp has the metal decoration effect but does not require a laser engraving process, reducing the cost of the laser engraving process.

All mood lamps with the dynamic effect according to the exemplary embodiment of the present disclosure are exemplified that the cover 2 and the bracket 1 are positioned on the same horizontal plane. However, an angle of the overall mood lamp may be arbitrarily adjusted according to actual design requirements. For example, the cover 2 may be provided above the bracket 1 (i.e., rotating FIG. 5 counterclockwise by 90 degrees), the cover 2 may be provided below the bracket 1 (i.e., rotating FIG. 5 clockwise by 90 degrees), or the cover 2 may be provided diagonally on an upper portion of the bracket 1.

In an exemplary embodiment of the present disclosure, because the cover 2 includes a Polycarbonate (PC) material, and an external surface of the cover 2 is a flat plane (see FIG. 3 and FIG. 4) to be still flat when actually touched, a stereoscopic layered feeling is visually but not excessively emphasized, improving the overall aesthetics and luxury feeling of the internal decoration of the vehicle.

In an exemplary embodiment of the present disclosure, the external surface of the cover 2 may undergo a leather pattern process to form a translucent matte effect. Therefore, when the power of the light source 4 is turned off, the mood lamp becomes a decoration panel with a matte effect of a wave pattern, improving the layered feeling and luxury feeling of the interior material of the vehicle.

In an exemplary embodiment of the present disclosure, as shown in FIG. 4, the surface of the light guide plate 3 including a wave pattern forms the metal plating layer 32 through vacuum aluminum plating or vacuum chrome plating.

Here, a different metal may be selected as a material of the metal plating layer 32.

In an exemplary embodiment of the present disclosure, as shown in FIG. 5 and FIG. 6, an edge portion of the cover 2 is provided on an interior material 7 of the vehicle to form an exposed portion 22 and an insertion portion 23.

The area of the light guide plate 3 is greater than that of the exposed portion 23 so that the entire exposed portion 22 may be irradiated by the light passing through the light guide plate 3, and an inclined transition portion 31 is formed at a position of the light guide plate 3 corresponding to the insertion portion 23 so that a straight edge portion does not exist, preventing a light output state of an end portion from becoming dark.

The mood lamp with the dynamic effect according to various exemplary embodiments of the present disclosure is fixed to an internal decoration panel of the vehicle such as a dashboard (see FIG. 8) and a door panel so that the internal decoration of the vehicle can generally establish a high-tech feeling.

In an exemplary embodiment of the present disclosure, the light source 4 is supported by an upper wall 12 or a lower wall of the bracket 1, and the light source 4 is positioned outside a range covered by the exposed portion 22.

In an exemplary embodiment of the present disclosure, as shown in FIG. 5 and FIG. 6, the light source 4 is supported by the upper wall 12 of the bracket 1 and is positioned outside the range covered by the exposed portion 22 to directly irradiate only the light reflective film 5, therefore, brightness is prevented from being uneven because the light source 4 is directly irradiated to a portion corresponding to the exposed portion 22 of the light guide plate 3.

In an exemplary embodiment of the present disclosure, the light reflection film 5 and the light guide plate 3 form a predetermined narrow angle.

In an exemplary embodiment of the present disclosure, as shown in FIG. 5 and FIG. 6, the bracket 1 is provided with an inclined surface 13, the inclined surface 13 becomes gradually away from the light guide plate 3 as the height thereof increases, and a lower portion of the light reflective film 5 is provided on the inclined surface 13 so that the light reflective film 5 and the light guide plate 3 form a constant angle. The light of the light source 4 is directly irradiated to the light reflection film 5, and the light reflected by the light reflection film 5 passes through the light guide plate 3, improving the overall brightness and light transmission uniformity of the mood lamp.

In an exemplary embodiment of the present disclosure, as shown in FIG. 7, the light source 4 includes a light source board 41 and one or more LEDs 42 provided on the light source board 41. The light source board 41 is electrically connected to a driving circuit board 6 for controlling the LED 42 through a plug assembly 43.

In an exemplary embodiment of the present disclosure, as shown in FIG. 7, 26 LEDs 42 may be provided on the light source board 41.

In an exemplary embodiment of the present disclosure, the light source board 41 includes two or more sub boards 411, and the respective sub boards 411 are electrically connected to each other through a plug assembly 44.

In an exemplary embodiment of the present disclosure, as shown in FIG. 7, the light source board 41 includes two sub boards 411, and the two sub boards 411 may be electrically connected to each other through the plug assembly 44, and 13 LEDs 42 may be provided on the respective sub boards 411.

Only one light source board 41 may be provided.

In the illustrated exemplary embodiment of the present disclosure, the two sub boards 411 are provided, but the number of the sub boards 411 may be adjusted according to circumstances.

In an exemplary embodiment of the present disclosure, the LED 42 is a smart LED, and the driving circuit board 6 includes a controller.

The controller may individually control each smart LED to implement various mood lamp effects.

When the power of the light source 4 is turned on, the controller may be configured to control the number of lighting and a lighting sequence of the LEDs by controlling color, brightness, fade-in and fade-out times of each LED so that the mood lamp may implement various dynamic effects, such as a flow gradient, a breathing lamp, and an acoustic gradient, etc.

When the mood lamp is applied to the interior of the vehicle, various interconnection functions such as speed interconnection, driving mode interconnection, speeding notification, air conditioning interconnection, voice recognition and air quality interconnection may be added.

In an exemplary embodiment of the present disclosure, the power of the LEDs 42 is 0.1 W to 1 W, and a distance between the respective LEDs 42 is 20 mm to 40 mm.

In an exemplary embodiment of the present disclosure, the power of the LEDs 42 is 0.2 W, and the distance between the respective LEDs 42 is 30 mm.

The vehicle according to the exemplary embodiment of the present disclosure is provided with the mood lamp with the dynamic effect.

An operation of the mood lamp with the dynamic effect of the present disclosure will be described below with reference to the drawings.

When the light emission of the mood lamp is required, the power of the light source 4 is controlled to be turned on through a related switch. In the instant case, LED 42 of the light source 4 generates light, and the light of the LED 42 of the light source 4 is reflected by the light reflective film 5 and then passes through the light guide plate 3 and the cover 2 to implement light emission. Because the light source 4 is close to the one side of the light guide plate 3 and far away from the other side of the light guide plate 3, the mood lamp may emit light so that the brightness is gradually changed.

By controlling the driving circuit board 6 through an apparatus such as a center console of the vehicle, the LEDs 42 of the light source 4 may be controlled to produce different dynamic effects.

When the light emission of the mood lamp is not required, if the power of the light source 4 is controlled to be turned off through the related switch the LED 42 of the light source 4 does not generate light. The mood lamp becomes the decoration panel with the metallic decoration effect of the wave pattern, improving the layered feeling and luxury feeling of the vehicle interior material.
