Description
Technical field
The utility model relates to a kind of heat abstractor, and particularly, the utility model relates to the heat sink radiating subassembly of a kind of novel light emitting diode (LED) illuminating source automobile headlamp.
Background technology
The semiconductor lighting technology is energy-conservation because of it at present, the life-span long and excellent photoelectric characteristic is widely used.
Yet, because light emitting diode all is converted into heat energy above 70% electrical power, and the temperature resistant capability of its node is poor, therefore when using, LED must consider heat radiation, make the junction temperature of device be lower than limit value, otherwise can cause LED decrease in efficiency, life-span reduction, photochromic skew, lose efficacy even.
Usually, power-type LED as LED car headlamp light source is in the narrow and small enclosure space, thus, make that its radiating condition is poor, heat mainly in lamp body the mode by free convection be delivered to the surrounding environment and go, cause present car light radiating condition can't satisfy the heat radiation requirement in use of LED car headlamp thus.
Heat sink (heat sink) industrial to be meant miniature water-cooling sheet, is used for the cool electronic chip.Thus, it is heat sink 3 that the heat that makes LED device 2 produce is directly passed to, and the fin of the band radiator fan of heat by extending to lamp body 1 outside is delivered in the surrounding environment and goes then.Because heat directly by the heat sink lamp body external environment condition that passes to, has reduced heat transfer space.
Car headlamp utilizes the existing problem that can't satisfy light emitting diode work of natural heat dissipation of lamp housing in the prior art, therefore needs the heat sink radiator structure of car light of design specialized.
The utility model content
For car headlamp in the solution prior art utilizes the existing problem that can't satisfy light emitting diode work of natural heat dissipation of lamp housing, the utility model provides a kind of novel heat sink radiating subassembly of LED source car headlamp, and described assembly is a kind of heat sink assembly that directly contacts with luminescent device.
For achieving the above object, the utility model adopts following technical scheme:
A kind of heat sink radiating subassembly of LED car light, described radiating subassembly comprises heat sink, be arranged at heat sink around, connected aluminium sheet, with the heat sink fin that is connected, it is characterized in that: the LED lamp directly place heat sink on, be fixed in the car light afterbody by the aluminium sheet around heat sink then, fin is arranged at a heat sink end face, and fin is connected with radiator fan.
According to the heat sink radiating subassembly of LED source car headlamp of the present utility model, it is characterized in that another heat sink end face directly contacts with the LED device.
Thus, the heat that makes the LED device produce is directly passed to heat sink, and heat is by the heat sink lamp body outside that spreads out of then, and heat sink conductive force is delivered in the surrounding environment by flange-cooled radiator fan and goes.
According to the heat sink radiating subassembly of LED source car headlamp of the present utility model, it is characterized in that the end that copper is heat sink comprises that LED is positioned at car light inside.
According to the heat sink radiating subassembly of LED source car headlamp of the present utility model, it is characterized in that fin and radiator fan stretch out from car light afterbody opening, the shape of aluminium sheet matches with the afterbody opening of car light.
According to the heat sink radiating subassembly of LED source car headlamp of the present utility model, it is characterized in that, described heat sink be that copper is heat sink.
The main effect of the fin of the heat sink afterbody of described copper is to increase area of dissipation.
Described radiator fan mainly increases heat sink convection transfer rate, and the mode of the heat that the LED device is produced by forced convertion is delivered in the environment around the lamp body and goes.
Advantage of the present utility model: heat directly by the heat sink lamp body external environment condition that passes to, has reduced heat transfer space, and test shows, this radiating subassembly is installed on the headlamp of Roewe concept car, in environment temperature is 80 ℃, when car light power is 40W, the LED junction temperature can be controlled in 120 ℃.
Description of drawings:
Fig. 1 is the heat sink heat radiation assembly structure schematic diagram of LED source car headlamp of the present utility model.
Figure 2 shows that the vertical view of Fig. 1.
Among the figure, 1 is the LED device, and 2 is the heat sink aluminium sheet on every side of copper, and 3 is that copper is heat sink, and 4 is radiator fan, and 5 is fin (fin).
The specific embodiment:
Below in conjunction with the drawings and specific embodiments the heat sink radiating subassembly of LED car headlamp of the present utility model partly is described further.
A kind of radiating subassembly that is used for the LED car headlamp.
As shown in Figure 1, described radiating subassembly comprises copper that has fin 5 heat sink 3 and radiator fan 4.Described copper is heat sink 3 openings that are installed on the car headlamp afterbody directly place the LED lamp on the copper heat sink 3, and the aluminium sheet 2 around heat sink is fixed in the car light afterbody by copper then.Copper is heat sink, and an end face of 3 closely contacts with the LED device 1 of heating, the heat that the LED device is produced receives transmission, the other end is connected with radiator fan 4 by fin 5, and the fin 5 of heat sink 3 tail ends and radiator fan 4 extend to the lamp body external environment condition to reach the heat radiation purpose.
3 size that described copper is heat sink and structure will be determined according to the needs of heat dissipation capacity and Vehicle lamp structure.
Advantage of the present utility model: heat directly by the heat sink lamp body external environment condition that passes to, has reduced heat transfer space, Test shows that this radiating subassembly is installed on the headlamp of Roewe concept car, is 80 ℃ in environment temperature, the car light merit When rate is 40W, the LED junction temperature can be controlled in 120 ℃.
