Description
Technical field
The utility model relates to a kind of LED street lamp.
Background technology
Traditional street illumination lamp, because it is backward in technique, be difficult to satisfy more and more higher instructions for use, thereby be eliminated gradually, the LED light fixture is tending towards universalness gradually in the application of field of street lamp lighting, adopt the LED street lamp can effectively solve the conventional lamp poor efficiency, the technological deficiency of highly energy-consuming, can satisfy higher instructions for use, yet, led light source chip in the LED light fixture is in efficient luminous, can produce a large amount of heats, and the driving power of led light source can also produce heat, especially the driving power of high-power LED street lamp, its temperature is higher, the heat that led light source and driving power thereof produced is as can not effectively being dispersed into the external world, then can have a strong impact on the service life of LED light fixture, and may bring potential safety hazard, therefore, the LED light fixture in use, need to be equipped with radiator, but in the existing LED street lamp, only be equipped with the radiator of the led light source heat that is used to leave and be not the radiator of driving power heat radiation, existing LED street lamp has been ignored the heat radiation to driving power, the heat that driving power produces can't effectively be distributed, and constantly the heat of accumulation not only influences the service life of LED light fixture, and has bigger potential safety hazard, normal use to the LED street lamp threatens, if and in the LED light fixture, be equipped with two radiators simultaneously, respectively led light source and driving power are dispelled the heat, then must cause LED street lamp internal structure more complicated, and strengthened the volume and weight of LED street lamp, more caused LED street lamp cost to rise.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of LED street lamp that dispels the heat comprehensive, effective, that volume is less, lower-cost is provided.
The technical solution adopted in the utility model is: the utility model comprises led light source, driving power, loam cake, described led light source is electrically connected with described driving power, described LED street lamp also comprises heat dissipating housing, described heat dissipating housing outside is provided with some radiating fins, described led light source is installed in described heat dissipating housing bottom, described heat dissipating housing top is provided with power slot, and described driving power is installed in the described power slot, and described loam cake cooperates with the opening part of described power slot.
Optimally, described loam cake is provided with fixed part, and described fixed part cooperates with the lamp stand of outside, is used for installing and fixed L ED street lamp.
Cover on described and also be provided with the waterproof connection jaws, power line passes described waterproof connection jaws and is connected with described driving power.
The utility model also comprises transparency protected mirror, and described transparency protected mirror cooperates with the bottom of described heat dissipating housing.
The beneficial effects of the utility model are: the utility model also comprises heat dissipating housing, described heat dissipating housing outside is provided with some radiating fins, described led light source is installed in described heat dissipating housing bottom, described heat dissipating housing top is provided with power slot, described driving power is installed in the described power slot, therefore, described heat dissipating housing can serve as the radiator of described led light source and described driving power simultaneously, in use, the heat that described led light source and described driving power produce all is delivered on the described heat dissipating housing, directly carry out heat exchange by some radiating fins on the described heat dissipating housing and extraneous air again, thereby fast heat is dispersed in the air, realize the high efficiency and heat radiation of led light source and driving power, ensure that the LED street lamp is stable, work safely, and has long service life, the radiator of led light source and the radiator of driving power are united two into one, heat that described led light source and driving power produce simultaneously can leave, heat radiation more comprehensively, radiating efficiency is higher, and simplified the overall structure of LED street lamp greatly, be more conducive to the installation and the maintenance of each parts, effectively reduce the volume and weight of LED street lamp simultaneously, further reduce the production cost of LED street lamp.
