As a further improvement of the above technical scheme：
Copper base is made of relatively thin copper sheet, filled with working fluid, stone in the heat exchanger core in the copper pipe shell of graphite film package
Ink film has very strong thermal conductivity.
The LED lamp holder material is aluminium alloy, and radiator portion is made of multiple curved surfaces, substantially increases radiating part
The heat dissipation area divided.
Reflective shell is set at LED lamp bead there are one window, not only protects LED lamp bead, and outer surface can be according to need
Ask adjusting position that the reflective surface of multiple and different angles is set：Reflective surface reflects by adjusting the light that angle sends out LED lamp bead

Specific embodiment
The technical solution of the utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of LED automobile lamp, structure is as shown in Figure 1, including LED lamp holder 2, two groups of LED light sources 4, graphite films 5.Two
The intermediate clamping connection graphite film 5 of group LED light source 4, two groups of LED light sources 4 and graphite film 5 are locked in LED lamp holder by holding screw 1
On 2.
LED light source 4 includes copper base and LED lamp bead, and LED lamp bead is embedded on copper base；Copper base is by relatively thin copper sheet
Composition, LED lamp bead is connect with power supply and providing electric energy by power supply makes LED lamp bead shine.
Graphite film 5 has very strong thermal conductivity, and graphite film 5 is enclosed with copper pipe, heat exchanger core is equipped in copper pipe shell.
Clamping connection graphite film 5 among the two panels copper base of two groups of LED light sources 4；Copper base and graphite film 5 pass through holding screw 1
It is locked in LED lamp holder 2, LED lamp holder 2, copper base is further reinforced using fixed pin 3, rubber ring 6 and Fixing clamp-seat 7
Connection between graphite film 5.
The rear end far from LED light source 4 is the radiator portion of petal-like groove composition in LED lamp holder 2, and outside is equipped with anti-
Light shell 8.Petal-like groove is made of multiple curved surfaces, and which greatly increases the heat dissipation areas of radiator portion, have fine
Heat dissipation effect.Stent material is aluminum alloy material, also enhances heat-conducting effect.There are one reflective shell 8 is set at LED lamp bead
Window, this not only protects LED lamp bead, and outer surface can set the reflective of multiple and different angles by adjusting position as desired
Face：Reflective surface is reflected into the light that LED lamp bead is sent out by adjusting angle the position on ground, and but also light does not have
Situation about being blocked by lamp body.
The mode of the heat transfer of graphite film 5 to the radiator portion at 2 rear portion of LED lamp holder is as follows：Graphite film 5 is wrapped up
Negative pressure is pumped into heat exchanger core in copper pipe shell, is then charged with certain working fluid, and half is that evaporator section half is in copper pipe
Condensation segment, when the liquid in heat exchanger core after one section of copper pipe is heated can evaporate, then steam flow under differential pressure the other end release it is hot
Amount condenses into liquid, then flow back to evaporator section by the effect of capillary force, constantly moves in circles, heat is so constantly transmitted to stent
Tail end radiator portion.The vapour of working fluid, liquid phase become heat transfer resistance very little, have the very high capacity of heat transmission, thermal conductivity factor
It is the hundred times of fine copper, increases the heat-conducting effect of lamp body.
The power circuit being connect with LED lamp bead is divided into rectification circuit and driving circuit, and driving circuit is placed in radiator portion
Center insulating portion, rectification circuit are set in the plug of circumscripted power line.Rectification circuit is circuit of synchronous rectification.Synchronous rectification
It is the field-effect tube of application, small volume is compared than traditional LED head car lights external power supply and saved many spaces.Driving electricity
Road part includes voltage regulator module, LED constant current drive module, LED protection modules and long-and-short distant light control module.
When LED automobile lamp works, the heat that LED lamp bead generates flows to copper base, then conduct to graphite film connected to it
5, the working fluid in the heat exchanger core in copper pipe that the heat of graphite film 5 is wrapped up by it absorbs, then under differential pressure action, heat absorption
The working fluid for becoming steam afterwards flows to radiator portion, and the heat carried discharges after being fully absorbed by large area radiator portion.
