led car headlight module

Abstract

The invention relates to a light emitting diode (LED) automobile headlamp module. The LED automobile headlamp module comprises a spotlight reflector cup, a sealing groove and an optics diffusion sheet, wherein the sealing groove is located at the front end of the spotlight reflector cup, and the optics diffusion sheet is arranged in the sealing groove. On the one hand, dipped headlight illumination is achieved after light rays of an LED lamp are converged by the spotlight reflector cup and horizontally diffused through the optics diffusion sheet, on the other hand, distant light illumination of the LED lamp is achieved after the light rays of the LED lamp are converged by the spotlight reflector cup and combined with filled liquid and the optics diffusion sheet. The LED automobile headlamp module is simple in structure, high in light use ratio of a light emitting unit, and convenient to use and operate due to the fact that switching between a distant light and a dipped headlight is achieved by filling a space between the sealing groove and a storage groove with the filled liquid and using an added drive device which can automatically achieve the switching between the distant light and the dipped headlight, and shows the advantage of microminiaturization of the LED lamp due to the fact that the overall structure of the LED automobile headlamp module is controlled in a small size.

Description

technical field [0001] The invention relates to an LED headlamp module, in particular to an LED automobile headlamp module. Background technique [0002] Compared with ordinary light bulbs, light-emitting diodes have significant advantages such as more energy saving, vibration resistance, long service life, and small size. Therefore, LEDs are more suitable for automotive lighting and indication. LEDs have been widely used in various car lights, such as instrumentation Lights, brake lights, turn signals, etc. [0003] At present, automobile headlights mainly use halogen lamps as the light source, and reflect the light in front of the car through the way of focusing and reflecting cups. Because the light efficiency of the halogen light source is lower than that of the LED, the heat generation is large, and the life is short, so the existing automobile headlights generally have the problems of high energy consumption, weak lighting, high heat generation, and short life, and th...

AI Technical Summary

Problems solved by technology

Because the light efficiency of the halogen light source is lower than that of the LED, the heat generation is large, and the life is short, so the existing automobile headlights generally have the problems of high energy consumption, weak lighting, high heat generation, and short life, and there are certain safety hazards

[0004] The structure of the existing automobile headlights is quite complicated. Although there are many types of automobiles that use LEDs as the light source of the headlights, the complex structure of the car lights makes the LED headlights have low light utilization efficiency and poor heat dissipation. , severe light attenuation, and the inability to form ideal high-beam and near-beam spots, etc., making it impossible to take advantage of the miniaturization of the light source of LED headlights

[0005] On the other hand, the existing various automobile headlights are mostly designed as separate modules for high beam and low beam, which is inconvenient to use.
