[0026] The light guide plate bracket 410 provides a mounting base for the transparent light guide plate 420 , and the light guide plate assembly 40 can be connected to the lampshade 10 of the lamp through the light guide plate bracket 410 .
[0027] The light guide plate is made of acrylic material or PC (Polycarbonate) material. The transparent light guide plate 420 is provided with laser engraving, V-shaped cross grid engraving, UV screen printing technology to print light guide points on the side facing the light guide plate bracket 410.
[0028] In the light guide plate assembly 40 disclosed in the present application, the light of the light source is transmitted through the transparent light guide plate 420, and then emits light of the corresponding color through the colored light guide plate 430. The staff can select the colored light guide plate 430 of the appropriate color according to the lighting requirements of the lamp, so that the lamps of the light guide plate assembly 40 with different colored light guide plates 430 can emit light of different colors to meet the needs of different customers.
[0029] The transparent light guide plate 420 and the color light guide plate 430 may be fixedly connected or detachably connected.
[0030] In the embodiment where the transparent light guide plate 420 and the color light guide plate 430 are fixedly connected, the transparent light guide plate 420 and the color light guide plate 430 are integrally formed, or are welded, or are adhesively connected.
[0031] In the embodiment where the transparent light guide plate 420 and the color light guide plate 430 are detachably connected, the transparent light guide plate 420 and the color light guide plate 430 are snap-connected, bolted, magnetically adsorbed, plug-in connected, etc.

[0033] There are many ways to connect the light guide plate assembly 40 and the lampshade 10 .
[0034] like Figure 1 As shown, a first connecting plate 421 is arranged on the circumference of the transparent light guide plate 420 of the light guide plate assembly 40, a second connecting plate 411 is arranged on the light guide plate bracket 410, the transparent light guide plate 420 is plug-connected with the slot or socket of the lampshade 10 through the first connecting plate 421, and the light guide plate bracket 410 is plug-connected with the slot or socket of the lampshade 10 through the second connecting plate 411.
[0035] The transparent light guide plate 420 and the light guide plate bracket 410 are connected to the lampshade 10 in a plug-in manner, which can reduce the difficulty of installing and disassembling the light guide plate assembly 40 on the lampshade 10 .
[0036] The transparent light guide plate 420 of the light guide plate assembly 40 may also be connected to the lampshade 10 by welding or bolts.
[0037] In some embodiments, the positions of the first connecting plate 421 and the second connecting plate 411 of the transparent light guide plate 420 and the light guide plate bracket 410 correspond to each other. After the transparent light guide plate 420 is assembled on the light guide plate bracket 410, the first connecting plate 421 overlaps with the second connecting plate 411, and the integral structure composed of the first connecting plate 421 and the second connecting plate 411 is inserted into the slot of the lampshade 10, so that the transparent light guide plate 420 and the light guide plate bracket 410 are synchronously fixed on the lampshade 10. In this embodiment, the step of separately connecting the transparent light guide plate 420 and the light guide plate bracket 410 can be omitted, which simplifies the assembly process of the lamp.
[0038] Optionally, the first connecting plate 421 and the second connecting plate 411 are equal in shape and size to reduce the difficulty of synchronously fixing the transparent light guide plate 420 and the light guide plate bracket 410 on the lampshade 10 .
[0039] In some embodiments, the first connecting plate 421 and the transparent light guide plate 420 are integrally formed, and the second connecting plate 411 and the light guide plate bracket 410 are integrally formed, so as to reduce the difficulty of processing the light guide plate assembly 40 .
[0040] like Figure 1 and Figure 2 As shown, there is a certain distance between the transparent light guide plate 420 and the light guide plate bracket 410, the first connecting plate 421 is an L-shaped connecting plate, the L-shaped connecting plate includes a vertical plate perpendicular to the transparent light guide plate 420 and a horizontal plate parallel to the transparent light guide plate 420, one end of the vertical plate is connected to the transparent light guide plate 420, and the other end of the vertical plate is connected to the horizontal plate, and the height of the vertical plate perpendicular to the plane where the transparent light guide plate 420 is located is the distance between the transparent light guide plate 420 and the light guide plate bracket 410; the second connecting plate 411 of the light guide plate bracket 410 is a horizontal plate, the horizontal plate of the L-shaped connecting plate is parallel to the second connecting plate 411, and after the transparent light guide plate 420 is assembled on the light guide plate bracket 410, the horizontal plate of the L-shaped connecting plate is connected to the second connecting plate 411.
[0041] The present application also discloses a lamp, which can be a front lamp of a car, a rear lamp of a car, or a lamp at other positions of a car.

[0052] The lampshade 10 is connected to the lamp housing 20 by snapping. Figure 2 As shown, the circumferential dimension of the lampshade 10 is larger than the circumferential dimension of the lamp housing 20 , the inner wall of the lampshade 10 is provided with a step surface matching the outer wall of the lamp housing 20 , and the lamp housing 20 is inserted into the lampshade 10 through the free end of the lampshade 10 and is snap-connected with the inner wall of the lampshade 10 .
[0053] In order to enhance the stability of the connection between the lampshade 10 and the lamp housing 20 , an auxiliary adhesive connection may be used at the connection position between the lampshade 10 and the lamp housing 20 .
[0054] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of the present invention.
