Technical Field

The invention relates to the field of automobile lamps, in particular to an automobile headlamp cooler.

Background

There are many kinds of bulbs for automobile headlamps, including halogen lamps, xenon lamps, LED lamps, and the like. The LED lamp has the characteristics of energy conservation, long service life, high brightness and the like, so the development is fast in recent years. However, since the LED lamp cannot withstand high temperature, the brightness and the service life are in a conflicting relationship. How to reduce the temperature of the headlamp becomes a bottleneck for further development of the LED lamp.

The large lamp shade of the automobile is sealed, so that the temperature of the inner space can be greatly increased by heat generated by the lamp bulb, the temperature can reach 130 ℃ at most, and the service life of the LED lamp bulb is not long due to overhigh temperature. In order to avoid overhigh temperature, some LED bulbs adopt a current reduction mode, when the temperature rises, the working current is reduced so as to avoid overhigh temperature, but the brightness of the lamp is greatly reduced, and the driving is influenced.

Disclosure of Invention

The invention aims to solve the technical problem that the automobile headlamp cooler can radiate heat inside an automobile headlamp cover to the outside, so that the internal temperature is greatly reduced. Therefore, the bulb can have more proper working temperature, the service life can be prolonged, and the bulb with the automatic current reduction function can not reduce the current too much.
