Abstract

The invention relates to a light-emitting structure of an automobile lamp thin-wall condenser. The light-emitting structure comprises an LED circuit board, LED particles and a corner thin-wall condenser, wherein the inner end of the corner thin-wall condenser is provided with a Fresnel pattern used for generating parallel light; a total reflection tapered plane is arranged at a corner part; the surface of the outer end of the corner thin-wall condenser is provided with a pattern capable of diffusing light; and the LED particles are fixed to the LED circuit board and correspond to the inner end of the corner thin-wall condenser in position. According to the light-emitting structure, a more uniform lighting effect can be achieved, the problems of LED granular sensation and lighting dark regions caused by traditional design are solved, the problem that a circuit board of a traditional direct condenser is visible can be effectively solved, and energy utilization rate is relatively high.

Description

technical field

[0001] The invention relates to a light-emitting structure of a thick-walled concentrator of a car lamp, belonging to the technical field of concentrators of a car lamp. Background technique

[0002] After the use of LED as the light source of car lights has become more and more popular, in addition to meeting the basic regulatory performance, more and more car lights have begun to pursue a more novel appearance, and the realization of lamp functions has become more and more diverse. Thick-wall concentrator is a commonly used way of realization. At present, the existing thick-walled concentrators have the following two conventional lighting forms:

[0003] 1. Using LED light source and thick-walled concentrator to directly illuminate:

[0004] Such as figure 1 As shown, the light emitted by the LED light source 1 is re-gathered through the Fresnel pattern on the back of the concentrator 2 to form parallel rays inside the concentrator, and finally diffuses ...

Examples

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] see image 3 , a light-emitting structure of a car light thick-walled concentrator, including an LED circuit board, LED particles 1, and a corner-type thick-walled concentrator 4; the inner end of the corner-type thick-walled concentrator 4 has a The Fresnel pattern has a total reflection inclined plane at the corner; the outer end surface of the corner type thick-wall concentrator 4 has a pattern that can diffuse light; the LED particles are fixed on the LED circuit board, and are connected with the corner type thick-wall concentrator The position of the inner end of the optical device 4 is corresponding.

[0025] In this example, see image 3 , the corner type thick-wall concentrator 4 is L-shaped.

[0026] In this example, see image 3 , the direction of the parallel light rays reflected by the inclined total reflection plane is c...
