The advantages of the crown series of street lamps 1.Can get a rectangular light spot, improves the uniformity of LED street lamps.2.Unique fence-type arc-shaped design, cooling plate uses aluminum of high cooling coefficient, the cooling area of a LED light of 1W is 15000 mm2. Large cooling surface area and the principle of air convection cooling, will disperse the heat of the LED lights quickly and effectively, to maintain the LED lights temperature at a low level, extend the lifespan of the LED lights.
