Automobile lamp III area lighting structure, automobile lamp condenser, automobile illumination module and automobile

Abstract

The invention relates to the technical field of automobile headlamp illumination, in particular to an automobile lamp III area illumination structure, an automobile lamp condenser, an automobile illumination module and an automobile. The car lamp III area lighting structure comprises a III area light inlet part and a III area light outlet part which are sequentially arranged in the light incidentdirection. The III area light incident part comprises at least two light transmitting pieces distributed in the horizontal direction, each light transmitting piece comprises a III area light incidentsurface, the structure of each light transmitting piece is suitable for forming a light expansion outline, and the normal direction of the III area light incident surface faces the III area light emergent part; and the light forming the region III enters the III area light incident surface, is diffused by the III area light incident surface, then irradiates the III area light emergent part, and finally exits from the III area light emergent part. The invention further relates to the automobile lamp condenser comprising the automobile lamp III area lighting structure, the automobile illumination module comprising the automobile lamp condenser, an automobile illumination device comprising the automobile lighting module and the automobile comprising the automobile lighting device. The III-area lighting structure of the automobile lamp has the advantages that the III area light shape is finely adjusted, and the influence on the high beam light shape is small.

Description

technical field [0001] The invention relates to the technical field of automobile headlight lighting, in particular to a lighting structure for zone III of a car light, a car light concentrator, a car lighting module and a car. Background technique [0002] With the application of concentrators in the low-beam or high-beam technology of automobile headlights, Zone III, as an important part of the low-beam light shape, is also an important part of the light distribution of headlamps required by regulations. The technical scheme of the lighting in zone III of the car lights has also been innovated and developed to a certain extent. [0003] For the prior art closest to the present invention, you can refer to the Chinese invention patent CN106122870B, which discloses a technical solution for the lighting structure of the III zone of the car lamp. The lighting device for the III zone is arranged on the upper surface of the concentrator, and It is a stepped structure with a cert...

AI Technical Summary

Problems solved by technology

This technical solution needs to be further improved: (1) the structure of this zone III has a greater impact on the optical path of the high beam, because the upper surface of the light collector is set as a total reflection surface of the high beam light, and the structure of zone III It is arranged on the upper surface and integrated with the upper surface, which destroys the upper surface of the light collector originally used as the total reflection surface of the high beam light, and has a certain impact on the performance of the high beam; It is not fine enough, because the light incident surface of the III area of ​​the scheme is a larger arc surface, which can adjust the overall light intensity of the light shape of the III area, but cannot well adjust the local light shape of the III area. The structure for locally adjusting the light shape in Zone III is a hole-like structure set locally on the light incident surface. This structure has limited ability to adjust the light shape.
