Background technique

With the rapid development of major new car-making forces, the competition is becoming more and more fierce, and consumers are paying more and more attention to the appearance of cars. The shape of car lights is also a huge plus for the appearance of the whole car. More and more OEMs spare no effort in the shape and innovation of car lights, adding many special shapes to achieve long-span and large-area light-emitting areas to impact consumers' visual senses. For the lighting of a certain area required by the main engine factory, and there are certain requirements for the uniformity of the lighting area, it is also necessary to make some modeling patterns for the lighting area. The usual method is to use LED direct light with a transparent inner light distribution mirror In the scheme, a large number of LEDs are tiled on the back of the transparent inner light distribution mirror. In order to have better uniformity, the distance between the LEDs and the inner light distribution mirror is required to be relatively large, and the number of LED particles is also required to be large. In this case, the It takes up a relatively large interior space of the lamp, and the cost is relatively high.

Utility model content

The purpose of the utility model is to provide a car light emitting structure with simple structure, soft light and narrow space, and at the same time, the cost is relatively low.

In order to achieve the above object, the utility model provides the following technical solutions:

A light-emitting structure for a car lamp, comprising a bracket, a light guide plate, an inner light distribution mirror, and a bezel arranged sequentially from the inside to the outside. The surface faces the direction of the inner light distribution mirror, the light incident surface and the light emitting surface are located on two adjacent sides of the light guide plate, and the surface of the inner light distribution mirror facing away from the light guide plate has a painted radium carving surface, so The surface of the reflective surface on the light guide plate is distributed with a number of micro-optical surfaces, which reflect the light entering from the light-incident surface to the light-emitting surface; the position of the light-incident surface on the side of the light guide plate is fixed with a The light source board arranged on the surface, the light source board light-emitting unit adopts LED particles.

The thickness of the light guide plate is 2mm-2.5mm.

The micro optical surface is similar to a hemispherical optical surface.

The light guide plate is made of PC or PMMA.

The light guide plate is fixed on the bracket by screws.

The thickness of the inner light distribution mirror is 2mm~3mm.

The internal light distribution mirror is made of PC or PMMA.

The inner light distribution mirror is fixed on the trim ring.

The beneficial effects of the utility model are:

1) The side light takes up less space than the bottom direct light;

2) The number of LEDs is greatly reduced, and a small number of LEDs light up a large area, saving costs;

3) The inner light distribution mirror has strong light uniformity, which makes the brightness of the light-emitting area more uniform, and the surface can be painted or aluminized with radium carving patterns, and the shape is more diverse and three-dimensional.

Detailed ways

As shown in Figures 1, 3, and 4, a light-emitting structure for vehicle lights includes a bracket 1, a light guide plate 2, a diffuser inner light distribution mirror 3 and a bezel 4 arranged in sequence from the inside to the outside, and the side of the light guide plate 2. Light source board 5. The "inner" refers to the direction close to the car body, and the "outer" refers to the direction away from the car body. The inner light distribution mirror 3 of the diffusion material is made of a milky white light-transmitting material, and the light guide plate 2 is made of a transparent material. For example, it can Made of PMMA or PC material. The bracket 1 fits the lamp body and fixes it. The light guide plate 2 is fixed on the bracket 1. The two can be fixed by locking screws. One of the sides of the light guide plate 2 is the light incident surface 2a, and the light guide plate 2 faces the inner light distribution mirror of the diffusion material. 3 is the light-emitting surface 2d, and the end surface facing the bracket 1 is the reflective surface 2b, and micro-optical surfaces 2c are distributed on the reflective surface 2b. 5. A light source is installed on the light source board 5, and the light source is usually an LED lamp bead. The propagation path of light in the light guide plate 2 is shown in Figure 2. The light emitted by the light source enters the light guide plate 2 through the light incident surface 2a, and then is totally reflected by the micro-optical surface 2c and then refracted by the light-emitting surface 2d and leaves the light guide plate 2. Light up the light distribution mirror 3 inside the diffuser material. The light distribution mirror 3 inside the diffusion material is fixed to the bezel 4, and surrounds the light guide plate 2. In appearance, only the light distribution mirror 3 and the bezel 4 inside the diffusion material are visible, and the inside light distribution mirror 3 of the diffusion material faces away from the light guide plate 2 There is a spray-painted radium engraving surface 3a on one side, the spray-painted area in the spray-painted radium engraving surface 3a can shield light, and the laser engraving area can transmit light, and patterns of different shapes can be produced according to needs. The size and density of the micro optical surfaces 2c on the light guide plate 2 can be adjusted as required to improve the brightness and uniformity of the illuminated area. The light refracted from the light-emitting surface 2d enters the light distribution mirror 3 in the diffusion material, and finally forms different shapes by painting the radium carving surface 3a. For example, rhomboidal regions, hexagonal regions or different patterns and patterns can be presented.
