Abstract
The utility model provides a forced air cooling heat dissipation structure for large-power street lamps. Compared with an existing natural air cooling heat dissipation structure for the large light-emitting diode (LED) lamps, the forced air cooling heat dissipation structure for the large-power street lamps is low in cost, small in size of a heat dissipation device, and good in heat dissipation effect. Moreover, large-power LEDs can work at low temperature so that brightness decay of the LEDs can be effectively controlled so as to improve normal service life of the large-power LEDs.
Description
Technical field
The utility model relates to the LED lighting technical field, particularly a kind of air blast cooling radiator structure that is used for large power road lamp.
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 have restriction, often the alloy radiator heat-dissipation is slower; The heat radiation power that this point has just formed radiator is not enough; The operating temperature of LED occupies high, causes the too early light decay of LED, influences ordinary life.The scheme that overcomes the above problems normally adds enough big radiator on cooling system, but strengthens radiator, and the overall volume of lamp, cost etc. all can raise to some extent, and this cost with market demands is low, volume is little, the reliability height deviates from mutually.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of air blast cooling radiator structure that is used for large power road lamp.
The utility model solves the technical scheme that its technical problem adopted:
A kind of air blast cooling radiator structure that is used for large power road lamp; Comprise lampholder shell, be socketed with lampshade, lampholder shell bottom outside the said lampholder shell bottom and be provided with the LED substrate, be arranged with some high-powered LED lamps on the LED substrate; Described lampholder shell top is provided with air inlet; The bottom is provided with air outlet, and lampholder shell is outside, and the alloy radiator is installed in the described lampholder shell; The alloy radiator is arranged on the lampholder shell bottom and is connected with the LED substrate, and the inner alloy radiator of lampholder shell top is provided with blower fan;
As the improvement of such scheme, described LED substrate is provided with the overtemperature prote device, and said overtemperature prote device is connected with the electronics constant-current source that lampholder shell top is provided with through circuit.
The beneficial effect of the utility model is: adopt the air blast cooling radiator structure of the utility model to compare with the air-cooled high-powered LED lamp radiator structure of existing natural; 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 controls the light decay of LED, to improve the ordinary life of great power LED.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
With reference to Fig. 1; A kind of air blast cooling radiator structure that is used for large power road lamp comprises lampholder shell 1, is socketed with lampshade 2 outside said lampholder shell 1 bottom, lampholder shell 1 bottom is provided with and is arranged with some high-powered LED lamps 4 on LED substrate 3, the LED substrate 3; Described lampholder shell 1 top is provided with air inlet 8; The bottom is provided with air outlet 9, and lampholder shell 1 outside is equipped with alloy radiator 5 in the described lampholder shell 1; Alloy radiator 5 is arranged on lampholder shell 1 bottom and is connected with LED substrate 3, and lampholder shell 1 inner alloy radiator 5 tops are provided with blower fan 6.
Described LED substrate 3 is provided with overtemperature prote device 7, and said overtemperature prote device 7 is connected with the electronics constant-current source 10 that lampholder shell 1 top is provided with through circuit.When high-powered LED lamp is worked; The startup work of also working together of air blast cooling radiator structure; Cold wind is got into by lampholder shell top air inlet, and cold wind is dirty in alloy radiator 5 in the effect of blower fan 6, gets rid of through the air outlet 9 of lampholder shell 1 bottom; Thereby the great amount of heat energy that produces when taking the work of LED street lamp out of is to reach purpose effective, quick heat radiating.Certainly, the utility model is not limited to above-mentioned embodiment, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection domain of the utility model.
