Problems solved by technology

Since the headlights of the car are located near the engine and work in an environment with high temperature and complex vibration characteristics for a long time, the heat dissipation performance of the headlights of the car will affect the service life of the headlights of the car; the existing LED headlights of the car are usually White LED lamp beads are used as direct light sources to emit light. On the one hand, the light efficiency is low and the light decay is serious. On the other hand, the heat generated is also large, which affects the service life of the car headlights.

Abstract

The invention discloses an LED automobile headlamp. The LED automobile headlamp comprises a lamp holder, a light source, a shaping lens, a light distribution lampshade and a driving controller. The driving controller is mounted on the lamp holder; the light source is mounted on the driving controller; the shaping lens is fixedly disposed outside the light source in a sleeving mode; the light distribution lampshade is arranged outside the shaping lens in a sleeving mode and fixed to the lamp holder; the light source includes a plurality of blue light LED chips which are distributed in an array mode; the driving controller is used for controlling the light source; and the shaping lens is formed by mixing and mold pressing of optical powder materials and fluorescent powder. By means of the LED automobile headlamp provided by the invention, the lighting effect is improved, light attenuation is reduced, moreover, the amount of generated heat is small, and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to an LED automobile headlamp. Background technique [0002] Energy saving, environmental protection, and intelligent manufacturing are important directions for the development of automotive lights. Since the headlights of the car are located near the engine and work in an environment with high temperature and complex vibration characteristics for a long time, the heat dissipation performance of the headlights of the car will affect the service life of the headlights of the car; the existing LED headlights of the car are usually White LED lamp beads are used as direct light sources to emit light. On the one hand, the light efficiency is low and the light decay is serious. On the other hand, the heat generated is also large, which affects the service life of the car headlights. [0003] The disclosure of the above background technical content is only used to assist in under...
