The utility model content
Not good in order to overcome the prior art illuminating effect, the deficiency of heat-sinking capability difference, the utility model provide a kind of illumination evenly, LED streetlamp with favorable radiating effect.
The utility model solves the technical scheme that its technical problem adopted:
The uniform LED street lamp of a kind of illumination comprises housing, is fixed on the diffuser on the housing; And be installed in the light emitting module in the housing; Described light emitting module is provided with one or more, and described diffuser is provided with light transmitting particles, and described light emitting module comprises gelled radiating bottom plate is set; And being installed in the LED lamp module on the radiating bottom plate, described LED lamp module outside is covered with the lens cover that increases the light scattering.
Do not interact in order to make between the light emitting module, described light emitting module parallel connection is provided with.
Further, described lens cover comprises lens and lens is fixed on the cover on the LED lamp module.
In order to improve the dispersion effect of LED lamp module, described lens outer surface is pillow, and the lower end level extends outward installs the limit.
In order to improve sealing property, be provided with sealing ring between described lens and the cover.
For the ease of installation and processing, said housing comprises Connection Block, and the left end cap and the right end cap that are installed in the Connection Block two ends.
For the ease of installing and fixing of LED lamp module, described left end cap is provided with the lamp stand support.
The beneficial effect of the utility model is: LED lamp module outside is covered with lens cover; Also be provided with light transmitting particles on the diffuser, can increase the scattering of light, the illumination range and the zone of each LED lamp monomer that distributes preferably; Light comparatively is evenly distributed in the zone of design; Can not form hot spot, practice thrift luminous energy, improve illuminating effect; The LED lamp module is installed on the radiating bottom plate; Radiating bottom plate is provided with fin, has increased the contact area with air, can accelerate the heat conduction through open free convection; Make the heat of radiator be delivered in the air rapidly; Prevent heat accumulation, played the effect of heat radiation, increased the service life of LED street lamp.
