Thick-wall part structure, light-emitting device and light-emitting mode

Abstract

The invention discloses a thick-wall part structure, a light-emitting device and a light-emitting mode. The thick-wall part structure comprises a light guide structure body, and the light guide structure body is provided with a light source incident plane, a first reflecting plane set, a second reflecting plane set and a light-emitting plane perpendicular to the light source incident plane; the first reflecting plane set is suitable for reflecting incident light in a plane perpendicular to the light-emitting plane and the light source incident plane and forming a central light-emitting area on the light-emitting plane; and the second reflecting plane set diverges the incident light towards two opposite sides parallel to the light-emitting plane, and forms a diffusion light-emitting area on the light-emitting plane, so that the light-emitting width on the light-emitting plane is greater than the width of the light source incident surface. Light emitting of the central area is guaranteed, meanwhile, the diffusion light emitting area is added, the light emitting width is larger than the initial irradiation width of the light sources, when the distance between the light sources is large, the area between the two light sources can be completely irradiated, dark areas are avoided, and the uniform light emitting requirement of customers is met.

Description

technical field [0001] The invention relates to an optical system structure applied to automobile lamps, and belongs to the technical field of automobile lighting. In particular, it relates to a thick-walled part structure, a light emitting device and a light emitting method. Background technique [0002] The mature development of LED light source technology has gradually replaced halogen bulbs as the preferred light source for vehicles. The development of LED light source makes the optical design scheme of LED light source, concentrator and thick-walled parts widely used in the design of car lights. However, with the in-depth research on non-imaging optics, designers and customers have more stringent requirements on the uniformity of non-imaging optics. [0003] The current structure of thick-walled parts can only emit light within the initial irradiation range of the LED light source, that is, the size of the light-emitting area is approximately equal to the size of the ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the structure of the thick-walled parts in the prior art can only emit light within the initial irradiation range of the LED light source, when the distance between the LED light sources is relatively large, the current lighting effect of the thick-walled part optical system will have obvious dark areas, which cannot meet the requirements. The technical problem of the customer's requirement for the uniformity of the car light, the invention provides a thick-walled part structure, a light emitting device and a light emitting method to solve the above problem
