DMD technology-based self-adaptive headlamp system suitable for solid state light source

Abstract

The invention discloses a DMD technology-based self-adaptive headlamp system suitable for a solid state light source. The system comprises a solid state light source module, a collimating, dodging andshaping part, a relay lens, a DMD digital light processing projection module, a compound paraboloid condenser, a bent light guide tube, a first projection lens and a second projection lens, wherein uniform rectangular light spots consistent with a digital micromirror array in dimension in the DMD digital light processing projection module are obtained by light rays sent by the solid state light source through the collimating, dodging and shaping part by means of the relay lens, and light rays reflected by the DMD digital light processing projection module are projected on the front side through the first projection lens to form main light sports; residual light rays are collected by the compound paraboloid condenser and the bent light guide tube and are projected to the front side throughthe second projection lens to form auxiliary light spots. Various self-adaptive automotive lamp light types are projected to achieve the functions of distance light and near light, meeting and AFS, so that self-adaptive illumination is achieved; and the system also has the advantages of being high in brightness, low in energy consumption, small in size and green and environment-friendly.

Description

technical field [0001] The invention belongs to the field of optical technology, in particular to a DMD technology-based self-adaptive headlight system suitable for solid-state light sources. Background technique [0002] Car headlights are installed on both sides of the front of the car and are mainly used to illuminate the road at night to provide drivers with more comfortable and safe driving. At present, automobile headlights have functions such as high beam, low beam, meeting vehicle extinction, AFS, etc., and to realize these functions, a single lamp or module is required to realize, and the headlight includes multiple lamps or modules. The headlight of the adaptive system is the main development direction of the future automobile headlight system. One way to realize it is to rely on the traditional car light system and add a mechanical deflection module to make the overall deflection of the car lights realize different light patterns. In this way, only simple light p...

Problems solved by technology

The common disadvantage of both is that the light types that can be realized are very limited

At the same time, there is no systematic analysis and modular design of the entire optical lighting system, and the substitutability of different light source modules is not considered
