LED automobile headlamp

Abstract

The invention relates to the technical field of automobile headlamps, in particular to an LED automobile headlamp, which comprises a front shell, a rear shell is arranged on one side of the front shell, a mounting sleeve is arranged at one end of the rear shell, the mounting sleeve communicates with the rear shell, an LED lamp holder is mounted in the mounting sleeve, the LED lamp holder extends into the rear shell from the interior of the mounting sleeve, a connecting mechanism capable of positioning the front shell and the rear shell is connected between the front shell and the rear shell, and a condensing lens mounting mechanism is arranged at the other end of the front shell. According to the invention, dirt on the inner side of the condenser can be cleaned without dismounting the front shell and the rear shell, and the purpose of saving cleaning time is achieved during cleaning.

Description

technical field [0001] The invention relates to the technical field of automobile headlights, in particular to an LED automobile headlight. Background technique [0002] Automobile headlights are automobile headlights, which are installed symmetrically on both sides of the front end of the vehicle in order to distinguish the lighting fixtures of the front view when driving at night. LED is a kind of electroluminescent device, which uses solid semiconductor chips as light-emitting materials, and directly emits light through the recombination of carriers to cause photon emission. LED headlights are lighting appliances manufactured using LEDs as light sources. Previous LED car headlights have some shortcomings. First, when the condenser lens in front of the car headlight is used for a long time, there will be some stubborn dirt on the surface of the condenser lens. The inner side of the condenser affects the light transmittance of the condenser, which leads to the need to disa...

AI Technical Summary

Problems solved by technology

LED headlights are lighting appliances manufactured using LEDs as light sources. Previous LED car headlights have some shortcomings. First, when the condenser lens in front of the car headlight is used for a long time, there will be some stubborn dirt on the surface of the condenser lens. The inner side of the condenser affects the light transmittance of the condenser, which leads to the need to disassemble the front shell and the rear shell of the headlight to clean up the stubborn dirt on the inner side of the condenser, which is easier to clean. It is time-consuming and cumbersome. In addition, when the headlights used to dissipate heat, they simply dissipated heat from the LED lamp head, but in fact, when the headlights are used for a long time, the temperature of the inner shell of the entire LED car headlights is also relatively high. Yes, the effect of partial heat dissipation is not very good, which will reduce the service life of the LED lamp head to a certain extent, and accelerate the aging of the shell of the LED car headlight.
