Features:
1.Global initiative, Independent R&D of constant current source, extended the lifespan of lighting through providing low loss constant voltage power driving.
2.World first patented spike-structure, Die-Casting Aluminum alloy housing which improves the heat dissipation effects greatly.
3、Superior tempered glass diffuser with high light transmittance and invariant color
4.Each LED configurate independent secondary optical system, light extraction efficiency is as high as 93% above, the luminous efficiency reached 80 lm/w above.
5. Special optical system, according to the road and the continuity of the visual , reasonable control the distribution of light, ensure good roads intensity of illumination and light evenness .maximize the efficiency of light ,fully embodies the” humanized designing”.
Application :
LED street lamp 20W widely used in highway, express way, Main Road , branch, tributary and sidewalks and residential area road lighting and square, playground, etc.
