Light source uniform device for vehicle tail light

The present invention relates to a uniform device for a light source of a taillight of a vehicle, and particularly relates to an innovation that makes the light-transmitting convex portions of different shapes, lengths, and thicknesses uniformly illuminate the light source, each of which is irregular and has a uniform uneven surface. The light-transmitting convex portion not only has the effect of uniform light emission, but also has the functions of enhancing blooming and preventing glare of the light source.

Referring to FIG. 1 , the optical structure of the light guide strip disclosed includes: a light guide body A having a light exit surface A1 corresponding to the bottom surface A2 of the light exit surface A, which is set to be a uniform rough surface; a sheet B of the bottom surface A2, which forms a diffusing layer B1 facing the bottom surface, the diffusing layer B1 is a uniform rough surface; and at least one light source C disposed on the circumferential surface of the light guiding body A, the light source C Light is generated into the interior of the light guide body, and part of the light travels to the diffusing layer B1 of the sheet body, and the diffused light is projected forward from the light exiting surface A1.

The above-mentioned optical structure of the light guide bar still has the following disadvantages to be improved:

1. The light guide body A is a strip-shaped structure having an irregular shape, and the light source C is disposed on the circumferential surface of the light guide body A, and the light guide body A cannot uniformly illuminate the light source C. The common peripheral surface is brighter. The shortcomings of the middle section are not bright.

2. The above-mentioned light guides A having different lengths, irregular shapes and different thicknesses must be separately formed, and most molds are required to participate in production, and the manufacturing cost thereof is high and needs to be improved.

The main purpose of the present invention is to provide an innovation that allows light-transmitting convex portions of different shapes, lengths and thicknesses to be uniformly transmitted through the light source, and each of which is irregularly arranged and has a transparent convex portion whose surface is uniformly uneven. It not only has the effect of uniform illumination, but also has the function of enhancing the fading and preventing the glare of the light source.

In order to achieve the above-mentioned purpose and effect, the present invention provides a light source uniform device for a vehicle taillight, which is disposed in a base of a taillight of a vehicle and a lamp housing, and includes: a set of light source exporting plates disposed inside the lamp housing. The front end surface of the light source lead-out plate is provided with a plurality of light-transmitting convex portions, and a light guiding plane is formed between the adjacent light-transmitting convex portions and the light-transmitting convex portions. a light source positioning seat disposed on the inner side of the light source lead-out board, wherein the outer surface of the light source positioning seat is provided with a plurality of first light-emitting elements and a plurality of fluorescent light-transmitting portions, and the first light-emitting elements are disposed corresponding to positions and shapes of the light guiding planes The fluorescent light transmitting portion is disposed corresponding to the position and shape of the light transmitting convex portion. The plurality of arrays are disposed on the light source circuit board inside the light source positioning seat, the light source circuit board is disposed corresponding to the position and shape of the fluorescent light transmitting portion, and the outer surface of each light source circuit board is provided with the second light emitting element.

The surface of the light-transmitting convex portion of the light source lead-out plate is set to be a uniform uneven matte surface.

The fluorescent light transmitting portion is set to be white.

The light source positioning seat is set to be opaque.

The light of the second light-emitting element is set to red.

The first and second light-emitting elements are LED lamps.

The light source uniform device of the tail light of the present invention has the following advantages:

1. The creative light source is evenly connected to all relevant components, and the technical means adopted are innovative, and have the novelty that has not been thought of in the same category.

2. The light source lead-out board of the uniform light source device of the present invention is formed by integrating a plurality of light-transmitting convex portions having different shapes, different lengths and different thicknesses, thereby saving the manufacturing cost and the light guiding effect.

3. The surface of the light-transmitting convex portion of the original light source lead-out plate is provided with a uniform uneven matte surface, which has the advantages of uniform brightness of the second light-emitting element, increase of blooming effect and prevention of glare of the light source.

4. The fluorescent light transmitting portion and the light transmitting convex portion corresponding to the same shape and the same shape can be visualized by the light source of the second light emitting element, and the red light strips having different shapes, different lengths and different thicknesses can be displayed. The connection relationship of its related components is progressive.
