Abstract
The utility model discloses a forced air-cooled heat dissipation structure of a high power LED lamp, the forced air-cooled heat dissipation structure comprises a lamp socket housing, a lampshade, an LED substrate, a high power LED lamp, an air blower and an alloy radiator. The structure is characterized in that the alloy radiator is arranged in the lamp socket housing and is oppositely contacted with the LED substrate via the bottom of the lamp socket housing, meanwhile, the miniature heat dissipation air blower is arranged between a wind baffle board and the alloy radiator. The work principle of the structure is that when the high power LED lamp is turned on, forced air-cooled heat dissipation structure is started simultaneously, cold air enters into the lamp socket housing from the top inlet and flows by the wind baffle board which is capable of obstructing the backflow of the airflow of the alloy radiator, then the cold air flows by the alloy radiator and the sheet slits of the radiator as well as discharges out from the outlet at the bottom of the lamp socket housing under the effect of the miniature heat dissipation air blower, therefore, the great amount of heat energy generated by the working high power LED lamp is brought out to achieve the aim of effective and fast heat radiation.
Description
Technical field
The utility model relates to a kind of lighting, especially a kind of high-powered LED lamp air blast cooling radiator structure.
Background technology
Existing high-power LED illuminating lamp decorations are to adopt the metal alloy fin mostly, the nature air swept type radiator structure, and such heat treatment structure is had relatively high expectations to the material of radiator and the heat radiation power of radiator.The nature air swept type radiator structure than high-powered LED lamp on.The overall dimensions of lamp can be restricted, and often the alloy radiator heat-dissipation is slower, and the heat radiation power that this point has just formed radiator is not enough, and the operating temperature of LED is acute high, will cause the too early light decay of LED, influences ordinary life.The scheme that overcomes the above problems adds enough big radiator normally at cooling system, but strengthen radiator, and the overall volume of lamp, cost etc. all can have rising, and the cost of this and market demands is low, volume is little, the reliability height is incompatible as fire and water.
Summary of the invention
Development purpose of the present utility model is to overcome the defective of above-mentioned prior art, and a kind of good heat dissipation effect, cost is low, volume is little, reliability is high high-powered LED lamp air blast cooling radiator structure are provided.
A kind of high-powered LED lamp air blast cooling radiator structure of the present utility model, comprise lampholder shell, lampshade, LED substrate, high-powered LED lamp, blower fan, the alloy radiator, it is characterized in that: the alloy radiator is installed in the described lampholder shell also is connected with the opposing contact of LED substrate by the lampholder shell bottom, simultaneously, also have miniature cooling fan to be installed between wind isolation board and the alloy radiator.
Described lampholder shell top has air inlet, and the bottom has air outlet.
Also having the electronics constant-current source is connected with miniature cooling fan while circuit with high-powered LED lamp.
Also having the overtemperature prote device is installed on the LED substrate and with the electronics constant-current source circuit and is connected.
Its operation principle is: when high-powered LED lamp is worked, the air blast cooling radiator structure also starts work simultaneously, cold wind is entered by lampholder shell top air inlet and flows through wind isolation board, the effect of wind isolation board is to intercept the air-flow of alloy radiator to flow backwards, cold wind is dirty on the alloy radiator in the effect of miniature cooling fan, flow through the again sheet crack of radiator, air outlet by the lampholder shell bottom is discharged, thereby a large amount of heat energy that produce when taking high-powered LED lamp work out of are to reach purpose effective, quick heat radiating.
Its beneficial effect is: adopt the air-cooled high-powered LED lamp radiator structure of air blast cooling radiator structure of the present utility model and existing natural to compare, it is low to have cost, little, the good heat dissipation effect of radiator volume, great power LED is in work under the low-temperature condition, effectively control the light decay of LED, to improve the ordinary life of great power LED.

The specific embodiment
Embodiment one:
As Fig. 1,2, shown in: a kind of high-powered LED lamp air blast cooling radiator structure of the present utility model, comprise lampholder shell 1, lampshade 2, LED substrate 3, high-powered LED lamp 4, it is characterized in that: alloy radiator 5 is installed in the described lampholder shell 1 also is connected with the 3 opposing contacts of LED substrate by lampholder shell 1 bottom, simultaneously, also have miniature cooling fan 6 to be installed between wind isolation board 7 and the alloy radiator 5.
Described lampholder shell 1 top has air inlet 8, and the bottom has air outlet 9.
Also having electronics constant-current source 10 is connected with miniature 6 while of cooling fan circuit with high-powered LED lamp 4.
Also having overtemperature prote device 11 is installed on the LED substrate 3 and with electronics constant-current source 10 circuit and is connected.
Its operation principle is: when high-powered LED lamp 4 work, the air blast cooling radiator structure also starts work simultaneously, cold wind is entered by lampholder shell 1 top air inlet 8 and flows through wind isolation board 7, the effect of wind isolation board 7 is to intercept the air-flow of alloy radiator 5 to flow backwards, cold wind is dirty on alloy radiator 5 in the effect of miniature cooling fan 6, flow through the again sheet crack of radiator 5, air outlet 9 by lampholder shell bottom 1 is discharged, thereby a large amount of heat energy that produce when taking high-powered LED lamp 4 work out of are to reach purpose effective, quick heat radiating.
