Abstract
The utility model relates to an LED (Light-Emitting Diode) street lamp mainly comprising a lamp shade, wherein the lamp shade is divided into a luminous source receiving part and a lamp rod connecting part; the luminous source receiving part is closed through a lower cover of the lamp shade and a reflecting shade; the luminous source receiving part is internally provided with symmetrical LED luminous sources, and the position of the LED luminous sources is matched with the shape of the reflecting shade; and the back part of the luminous source receiving part is provided with heat radiation fins in arrays. The LED street lamp is characterized in that the luminance of the LED street lamp is improved through both luminous sources, and simultaneously good heat radiation effect is achieved through the heat radiation fins; the LED street lamp has novel structure and design, is a perfect solution to the problem of heat radiation of an LED light source through the novel heat radiation fins and a heat radiation circuit, and has low energy consumption, and the LED light source with high luminance can be combined with a street lamp for use; and meanwhile, the LED street lamp adopts an LED surface light source as the luminous source, the lamp light emitted totally coincides with and even exceeds the requirements of the street lamp for luminance, and is provided with a special protection waterproof cover, and therefore, the service life of the LED street lamp is effectively prolonged.
Description
Technical field
The utility model relates to a kind of lighting, especially a kind of LED street lamp.
Background technology
Along with the progress of society, reduction of income carbon emission amount is slowly a big theme that becomes current society, and street lamp is a requisite city instrument in the human urban society, because street lamp is in outdoor, desired illumination zone is big, and brightness requirement is big, so the power consumption of street lamp is huge.And LED is a kind of new type light source of newly-developed, have low in energy consumption, the characteristics that brightness is big.But very difficult led light source is combined on the street lamp of prior art used, because the caloric value of LED is huge, limited the volume of LED individual light sources, go its accessible peak power thereby also limited, sometimes the LED of some limit approach making can meet the requirements of peak power, but its service life is shorter relatively again.As the higher brightness demand is can only assemble by a plurality of LED small light sources to reach target, such production process complexity, the cost height, solution heat dissipation problem that simultaneously also can't be good makes that this novel light source of LED can't effectively be used in the field of street lamp.
The utility model content
The purpose of this utility model is to provide a kind of good illumination effect, long service life, and the low LED street lamp of energy consumption for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the LED street lamp that the utility model is designed, it mainly comprises lampshade, lampshade is divided into light emitting source accommodation section and lamp stand connecting portion, the light emitting source accommodation section is by lampshade lower cover and reflection shield sealing, be provided with the LED light emitting source of symmetry in the light emitting source accommodation section, the position of LED light emitting source and the form fit of reflection shield, the back of light emitting source accommodation section is provided with the fin of array.This result's characteristics are the brightness that improves the LED street lamp by two light emitting sources, reach better heat radiating effect by fin simultaneously.
In order further to improve radiating effect, described led light source contact with fin by heat-radiation loop, and the curve on described fin top is connected the formation camber line with the other parts cooperation of lampshade, thus the uniformity of assurance street lamp configuration design.
In order further to improve the performance of illumination, reduce the heating of led light source, its described led light source is an area source LED lamp.The LED area source compares with the LED spot light that to have caloric value little, and volume is little, and luminosity is big and uniform characteristics.
In order further to prolong the service life of LED street lamp, be provided with bucker in its described lamp stand connecting portion, enter in the street lamp by the seam of LED street lamp and light pole to prevent rainwater, street lamp is exerted an influence.
The resulting LED street lamp of the utility model, the structural design novelty by novel fin and radiating loop structure, has perfectly solved the heat dissipation problem of led light source, thereby has made energy consumption low, and the led light source that brightness is big can be used in combination with street lamp.This LED street lamp has also designed employing LED area source as light emitting source simultaneously, and the light that sends meets even exceed the brightness requirement of street lamp fully, and has special protection bucker, can effectively prolong the service life of this LED street lamp.In sum, the LED street lamp that the utility model is designed, it is long to have a life-span, the brightness height, lighting effect is good, characteristics low in energy consumption.
