Abstract

The invention discloses a light distribution device of an LED light source, an automobile headlight provided with the light distribution device, and an automobile. The light distribution device of the LED light source comprises a reflecting mirror, a plurality of substrates, a plurality of LED lamps, a decorative frame and an internal lamp shade, wherein the shape of the reflecting mirror is formed to be at least a circumferential part of a roughly cylindrical shape; a reflecting decorative pattern is formed in the outer side wall of the reflecting mirror; light emitting holes are formed in the surface, located between the inner side wall and the outer side wall, of the reflecting mirror; the plurality of substrates are distributed on the inner side wall of the reflecting mirror along the circumference of the reflecting mirror; the plurality of LED lamps are arranged on the plurality of substrates respectively; the decorative frame is arranged on the outer side of the front end of the reflecting mirror in a sleeving manner and bends and extends outwards and backwards in a radial direction of the reflecting mirror approximately, and a hollow part is formed in the decorative frame; and the internal lamp shade is arranged on the rear side wall of the decorative frame. According to the light distribution device of the LED light source, annular lamplight which meets the requirements of laws and regulations and has a unique effect is formed, and the lamplight is attractive in modeling, simple in structure, and low in cost.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an LED light source light distribution device, an automobile headlight having the same, and an automobile having the automobile headlight. Background technique [0002] With the rapid development of automobile technology, people's requirements for the shape of automobile headlights are constantly increasing. The traditional halogen light source has a single shape and affects the spatial layout of the lamp room. As a light source for automotive lighting, LEDs not only have excellent light patterns and colors, but also have a longer life than halogen bulbs, and are more and more widely used in high-end models. In the application of automotive lamps, LEDs mostly appear in the shape of dots, strips, and strips, and the light output effect is single. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the...
