Abstract

The invention relates to the technical field of automobile lighting, and provides an automobile headlamp which comprises a low-beam incident optical system for generating a low-beam light beam, a distance light incident optical system used for generating a distance light beam, a heat dissipation substrate having one side provided with the low-beam incident optical system and the distance light incident optical system, and a light emitting device used for collecting the low-beam light beam and the distance light beam and outputting the low-beam light beam and the high-beam light beam. The low-beam light beam and the distance light beam respectively form a first light area and a second light area on the light incident surface of the light emitting device, the second light area is arranged above the first light area, and the first light area and the second light area are partially overlapped; and a distance light and low beam conversion device is arranged between the heat dissipation substrate and the light emitting device. According to the invention, local heat accumulation of the heat dissipation substrate can be avoided, the heat dissipation efficiency is improved, the light collection rate of the light emitting device can be improved, and the ultra-long-distance lighting effect can be achieved.

Description

technical field

[0001] The present invention relates to the technical field of automobile lighting, and more specifically, to an automobile headlamp. Background technique

[0002] The two light sources of the low beam light source and the high beam light source of the lens headlights in the prior art are respectively arranged on both sides of the heat dissipation substrate. All the heat is exported through the same heat dissipation substrate. Since the heat conduction channels of the two light sources basically overlap, this seriously affects the heat dissipation effect of the light source.

[0003] In addition, in order to improve the light collection efficiency and optical effect of the light-emitting lens, the distance between the two light sources in the vertical direction should not be too large, which will inevitably lead to the limitation of the thickness of the heat dissipation substrate between the far and near light sources, which also affects the front The heat ...
