Be provided with the water-proof sealing strip of coupling in the described diffuser holding tank.
Beneficial effect of the present invention
The present invention directly pastes high-power LED plane light source on the radiator, to obtain the shortest thermally conductive pathways.The fin of radiator has increased the area of dissipation of light fixture, and the big heat that produces is dispersed into air by divergent sheet during light source works, and the temperature of led light source PN junction is reduced significantly, and light efficiency and life-span improve greatly.
The present invention's while is according to the light characteristic that goes out of LED planar light source, adopting the light source angle on this radiator is 50 ° to 70 °, a side of light source is provided with super mirror reflector simultaneously, thereby has obtained the distribution curve flux of standard, can make the road surface of street lamp irradiation obtain uniform illumination.
Airtight light source inner chamber of the common formation of diffuser, water-proof sealing strip, radiating shell and connector among the present invention, thereby effectively stoped rainwater, dust to enter in the lamp inner chamber, provide sound assurance for led light source trouble free service and cloche keep high transmission rate.The aluminium flake that connects LED street lamp two sheet heat radiators, service hatch has been reserved in gather louvre and corresponding position, makes that the maintenance of LED street lamp is very convenient.
