The material attribute of the bracket 1 can be white material, so that the efficiency and the uniformity are improved.
The inner lamp housing 3 and the light guide plate 2 are made of transparent material, such as but not limited to PMMA or PC. When the light guide structure of the vehicular lamp of the present embodiment is applied to a specific vehicle, the bracket 1 is fixed to the vehicle body, and the light guide plate 2 is fixed to the bracket 1, which may be fixed by, for example, but not limited to, hot riveting.
The light guide plate 2 in this embodiment is a hexahedral structure, one of the side surfaces of the light guide plate 2 is a light incident surface 23, and a light source 4 is disposed on one side of the light incident surface 23 of the light guide plate 2; that is to say, the light guiding structure of the car light of the present embodiment adopts a side light entering mode. The light source 4 should meet the requirement of GB-4785 on the light colors of different functional lamps, for example, LED light sources 4 with light colors of white light, yellow light, red light, blue light and green light may be used.
When used for a side marker lamp, the light guide plate 2 may be appropriately thinned to leave a space for the rest of the structure, and preferably, the thickness of the light guide plate 2 is 1mm to 2.5mm. In a preferred embodiment of the present invention, the thickness of the light guide plate 2 is 2mm.
On the basis of the above structure, the light guide plate 2 in the present embodiment is molded with the optical diffusion structure 21 toward the side end face of the inner cap 3; and a dermatoglyph microstructure 31 is formed on the side end surface of the inner lamp shade 3 facing the light guide plate 2. The dermatoglyph microstructure 31 designed here can increase the hazy feeling and improve the effect of the lighting uniformity, so that the lighting effect of the surface light source 4 is shown as a whole. In the optional embodiment of the present invention, the inner lamp cover 3 is disposed in parallel with the light guide plate 2, and the gap between the inner lamp cover 3 and the light guide plate 2 is 1-10 mm.
It should be noted that the optical diffusion structure 21 in this embodiment may be a diffusion pattern structure, and may also be a plurality of micro optical monomers 11; and projections of at least two micro-optical monomers 11 of the plurality of micro-optical monomers 11 on a side end surface of the light guide plate 2 facing the inner lamp cover 3 intersect. That is, there is an overlapping area between the micro-optical units 11 with the projection on the side end surface of the light guide plate 2 facing the inner lamp housing 3, and it is found through practical research that the ratio of the overlapping area to the area of the projection of the micro-optical units 11 on the side end surface of the light guide plate 2 facing the inner lamp housing 3 is best between 5% and 50%.
