Description
Technical field
The utility model relates to automobile lamp technical field more particularly to a kind of LED free form surface mode transmission rear taillights.
Background technique
To guarantee safe driving, various traffic lights are installed on automobile.Automobile lamp has traffic safety critically important
Effect, therefore guarantee car light normal use tool play a very important role.But usually the Guang Yuanshi of car light is sealed in lamp housing
Inside, thus car light after a period of use, the temperature of lamp interior be it is very high, the service life of such car light will
It substantially reduces, therefore how to reduce the temperature of car light it is very important.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of LED free form surface mode transmission
Rear taillight.
The utility model is achieved through the following technical solutions:
A kind of LED free form surface mode transmission rear taillight, including light fitting base, illumination lamp housing, the light fitting base side is set
Several locking assemblies are equipped with, the light fitting base is internally provided with reflector, and the reflector is internally provided with LED substrate,
It is provided with several LED lamp beads on the LED substrate side wall, on the LED substrate side and is located at each LED lamp bead and passes through
Heat-conducting layer is connect with heat sink, is connect by heat transmission fin with heat-radiating substrate inside the light fitting base, and the heat-radiating substrate is logical
Heat dissipating layer is crossed to connect with radiating fin.
It is bonding connection between the heat-conducting layer and heat sink as the optimal technical scheme of the utility model.
As the optimal technical scheme of the utility model, the heat sink is made of copper material.
As the optimal technical scheme of the utility model, it is fixedly connected between the heat transmission fin and heat-radiating substrate.
As the optimal technical scheme of the utility model, the heat dissipating layer is thermal grease.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, design is reasonable,
The cooling mechanism of the LED automobile tail lamp of the utility model can effectively radiate to lamps and lanterns, prevent great power LED because using
Luminous intensity caused by electric current is excessive and electronic component are damaged lamp adverse effect.
