LED automobile anti-fog lamp

Abstract

The invention discloses a LED automobile anti-fog lamp, whose object is to provide a automobile anti-fog lamp with long service life, low use temperature and high photoelectric efficiency. The LED automobile anti-fog lamp includes: a casing, a front lens, a light gathering cup and a luminous body, wherein the front lens is installed on the casing in an embedding connection, the luminous body and the light gathering cup are installed in the casing, which is characterized in that: the luminous body is a yellow LED lamp string, wherein the front end of the LED lamp string has a light gathering cup, and the back end clings to the frontend of a heating body; a cavity is in the heating body; a water inlet is installed on the lower part of the cavity and a water outlet is on the upper part of the cavity; the water inlet and outlet are communicated with an automobile water tank through a water pipe. A driver of the LED lamp string includes: a LED drive circuit and a strong and weak light control circuit, wherein, the LED drive circuit has double input ends, one is a strong light control input end, and the other is a weak light control input end; the strong and weak light control circuit has double output ends, one is a strong light control output end, and the other is a weak light control output end.

Description

technical field [0001] The invention relates to an anti-fog lamp, in particular to an LED automobile anti-fog lamp. Background technique [0002] Automobile anti-fog lights include a housing, a front lens, a focusing cup, and a luminous body. The luminous body is an incandescent lamp. Good fog and high visibility of yellow light, for this reason, the front lens is made into a yellow filter, or the spotting cup is made into a yellow spotting cup. Chinese patent 200720113569.4 automobile anti-fog lamp and 98200351.X a kind of anti-fog lamp is exactly such a kind of incandescent lamp structure using tungsten wire, although this tungsten-filament type anti-fog lamp structure can make car light emit yellow light, but because Its illuminant uses incandescent lamps, which have high temperature, short service life and poor photoelectric efficiency, which are its disadvantages. Contents of the invention [0003] In view of the shortcomings of the prior art, the object of the pres...
