Description

High-brightness automobile headlamp

Technical Field

The utility model relates to the field of lighting technology, specifically a high brightness's car headlight.

Background

The development of automobile headlamps starts from tungsten filament lamps, and goes through element lamps and xenon lamps to the more popular LED automobile headlamps at present. Compared with other types of automobile headlamps, the LED automobile headlamp has the advantages of high brightness, long service life, quick start and the like, but the existing LED automobile headlamp has a technical bottleneck, namely the contradiction between brightness and heat dissipation, if the brightness is improved, the heat dissipation is inevitably increased, but the size of a lampshade is limited, a heat dissipation fin cannot be made too large, and if a fan is adopted for assisting the heat dissipation, the fan is easy to damage under the environment with higher temperature and due to dust and vibration. At the earliest time, a plurality of manufacturers achieve the power of the LED automobile headlamp to be 30-40W, the brightness is ideal, but the service life of the LED automobile headlamp is not long due to insufficient heat dissipation. Later, on the premise of ensuring heat dissipation, the power can only be 20 watts, and the brightness is slightly insufficient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a car headlight of hi-lite to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a car headlight of hi-lite, includes red copper heat conductor, heat conduction support and shell, the latter half of heat conduction support is installed inside the shell, and red copper heat conductor fixed mounting is on heat conduction support, and heat conduction support's top is equipped with the shield, and heat conduction support's bottom is equipped with the refrigeration piece, and the outside of refrigeration piece is equipped with the radiator, and the shell is inside still to be equipped with the lamp pearl, is equipped with the lamp pearl between refrigeration piece and the radiator.

As a further technical solution of the present invention: and a clamp spring support is arranged above the shell.

As a further technical solution of the present invention: the refrigerating piece is a semiconductor refrigerating piece.
