Summary of the invention
In order to solve the problems of the technologies described above, the purpose of the utility model be to provide a kind of simple in structure, radiating effect better, the LED street lamp of longer service life.
The complete skill scheme of the utility model is that a kind of LED street lamp comprises a shell, is provided with LED module, LED module support and radiating subassembly in the said shell; Said LED module comprises led light source and wiring board, said led light source setting in the circuit board, said wiring board is connected on the LED module support, said LED module support is provided with the heat conduction tube seat; Said radiating subassembly comprises heat pipe and heat pipe pressing plate, and an end of said heat pipe is inserted in the heat conduction tube seat of LED module support, and the other end is fixed on the housing through the heat pipe pressing plate; The another side of said module support is provided with a fan, is provided with a cavity between said fan and the shell, on the said shell with fan over against the place be provided with louvre.
Said shell lower surface led light source is provided with reflection shield over against locating to be provided with the LED guard shield between LED guard shield and the led light source, and said reflection shield is arranged on the said led light source through the reflection shield support.
The reflective surface of said reflection shield is a quadratic surface.
Therefore the utility model has following beneficial effect with present compared with techniques:
A kind of LED street lamp of the utility model comprises shell, LED module, LED module support and radiating subassembly, and the another side of LED module support is provided with a fan; Be provided with a cavity between fan and the shell, on the shell with fan over against the place be provided with louvre, the heat that the LED lamp is produced is discharged in street lamp as soon as possible; Can let the long-time operate as normal of street lamp; The longer service life that makes, product structure is simple simultaneously, installs also very convenient.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the utility model, constitutes the application's a part, does not constitute the improper qualification to the utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment
To combine accompanying drawing and specific embodiment to specify the utility model below, be used for explaining the utility model in the illustrative examples and the explanation of this utility model, but not as the qualification to the utility model.
Embodiment 1:
A kind of LED street lamp of present embodiment comprises a shell 1, is provided with LED module 2, LED module support and radiating subassembly in the shell 1; LED module 2 comprises led light source and wiring board, the led light source setting in the circuit board, wiring board is connected on the LED module support, LED module support is provided with the heat conduction tube seat; Radiating subassembly comprises heat pipe and heat pipe pressing plate, and an end of heat pipe is inserted in the heat conduction tube seat of LED module support, and the other end is fixed on the housing through the heat pipe pressing plate; The another side of module support is provided with a fan, is provided with a cavity between fan and the shell 1, on the shell 1 with fan over against the place be provided with louvre; Shell lower surface led light source is provided with reflection shield over against locating to be provided with the LED guard shield between LED guard shield and the led light source, and reflection shield is arranged on the led light source through the reflection shield support, and the reflective surface of reflection shield is a quadratic surface; Present embodiment LED street lamp lens material is the improvement optical material, transmitance >=93%, heatproof-38-+90 degree, 30000 hours characteristics such as no change of anti-UV ultraviolet ray ` xanthate ratio.It has extraordinary application prospect in the new city illumination.To the light modulation of the degree of depth, and color can not change because of light modulation with other characteristics.LED road lamp cooling technology, mostly general the use is the heat-conducting plate mode, is the thick copper coin of a slice 5mm, in fact is temperature-uniforming plate, falls the diffusing source of heat samming; Also have finned to dispel the heat, but weight is too big.Weight is very important on road lamp system; Because the street lamp height has 9 meters,, especially running into typhoon, earthquake and all possibly produce accident if too heavy danger just increases. present embodiment has adopted the needle-like heat dissipation technology; The radiating efficiency of needle-like radiator has a very significant increase than traditional sheet radiator; Can make the LED junction temperature lower more than 15 ℃, and water resistance is better than conventional aluminium Section Bar Heat Sinks, on weight and volume, also improves to some extent simultaneously than common radiator.
Therefore a kind of LED street lamp of the utility model comprises shell, LED module, LED module support and radiating subassembly; The another side of LED module support is provided with a fan, is provided with a cavity between fan and the shell, on the shell with fan over against the place be provided with louvre; The heat that the LED lamp is produced is discharged in street lamp as soon as possible, can let the long-time operate as normal of street lamp, the longer service life that makes; The utility model is simple in structure, and is easy for installation, and cost is low; Light weight, good heat dissipation effect, and also each item illumination index all meets relevant national standard.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
