Abstract

The invention relates to the technical field of headlight optics and structure of automotive LEDs and particularly relates to a small-size LED headlight assembly. By using an LED combined light source and additionally arranging a light screen, severe light distribution requirement of a dipped headlight of an automotive light can be met, and the dipped headlight can be made in a very small dimension and can be freely made according to actual space demands, so that the headlight assembly is suitable for more vehicle models and is higher in universality. By using the LED combined light source, the headlight assembly is lower in cost, more energy-saving and environmental-friendly, brighter and longer in service life. By using the non-transparent light screen of a metal plate structure, a joint is not formed at the boundary of a distance light and a passing light, dark strips are eliminated, and the vision of the driver is enhanced, so that the driver has better pavement driving experience; the passing light dark and bright intercepting line is more clear and straight, so that the dazzling feel of the vehicle is reduced; by using the fixed light screen, distance light and passing light are switched by way of igniting and quenching distance light beads, so that the distance light and passing light switching speed is faster.

Description

technical field [0001] The invention relates to the technical field of headlight optics and structure of automobile LEDs, in particular to a small-sized LED headlight assembly. Background technique [0002] There are two main ways for the low beam of the traditional LED headlight optical system. [0003] Low beam light mode 1: projection light scheme. It needs to be composed of an ellipsoid reflector, a visor and a lens. To have a good lighting effect, it is established by the following conditions: a dedicated flat-panel LED combined light source, an ellipsoid reflector with a diameter of 50mm or more, and a total size of 100mm or more in length. This kind of dipped beam method has the following disadvantages: the size is relatively large, and the cost of the LED light source is high. [0004] Low beam mode two: direct lens type. Special flat-panel LED combination light source, special optical lens. This low beam method has the following disadvantages: the cost of the LE...
