Description
Technical field
The utility model is related to auto lamp technical field, specifically a kind of LED automobile lamp of good heat dissipation effect.
Background technology
So that its small volume, long lifespan, low energy consumption, vibration resistance, startup time is fast etc., advantage has become young mobile to LED
The first-selection of light source technology.LED is a kind of injection lelctroluminescence device, in the presence of extra electric field, the radiation in electronics and hole
It is compound that part energy is converted into luminous energy, and remaining energy is converted into heat energy by the vibration of the lattice of radiationless compound generation.
To replace conventional light source in car headlamp for LED, it is necessary to possess high-power, high efficiency and operating temperature
In -40 DEG C~125 DEG C of high reliability.In these functional requirements are realized, wherein a more formidable part is radiating
Problem, for single led, if heat is concentrated in small-sized chip and can not effectively shed, can cause core
Piece temperature is raised, and causes the non-uniform Distribution of thermal stress, makes chip failure.
Automotive LED headlamp is limited due to space, and the vibration travel in addition during, the requirement to stability is very high, this
A little radiating difficulty for both increasing LED car lamp.Heat-conducting plate or heat pipe are it is possible to additionally incorporate in current most heat sink conception car light, is increased
Car light has been added to produce complexity.
Therefore, the temperature rise for how controlling LED automobile lamp is that LED keys in the urgent need to address in automotive lamp applications are asked
Topic.

Lamp, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of LED automobile lamp of good heat dissipation effect, including LED pieces, cylinder and lamp socket, the cylinder are arranged on lamp socket
Top, the LED pieces are arranged on the top of cylinder by lamp piece fixing hole, and it is recessed that the bottom of the lamp socket is provided with coolant
Groove, the side of coolant groove is provided with coolant inlet and cooling liquid outlet, and the inside of the cylinder and lamp socket is provided through
Cooling passage, the cooling passage and coolant groove UNICOM, are provided with coolant heat conduction mouthful, institute in the middle part of the cylinder
Coolant heat conduction mouthful and the cooling passage UNICOM are stated, the side of the lamp socket is provided with lamp socket fin, lamp socket fin
Outside lamp socket fin cover plate is installed, the bottom of the lamp socket is provided with lamp holder base plate, and the bottom of the lamp holder base plate is glued
Post base plate fan；Cylinder fin is provided with the cylinder, the outside of cylinder fin is provided with cylinder fin cover plate.
As the utility model further scheme：The lamp socket is arranged on auto lamp by Automobile lamp holder.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is simple and compact for structure, stable performance, using the coolant pair in coolant groove, cooling passage
LED pieces are radiated, and the heat for preferably sending the LED pieces is passed by the coolant heat conduction oral instructions, in addition, cold
But liquid and base fan can play multiple heat dissipation, and heat exchange efficiency is high, so as to extend the service life of LED automobile lamp.
