At present, the developed (30w, 40w, 50w, 60w, 72w, 90w, 120w, 150w, 250w) high power LED street lights adopt the American E-LITE-CWT/WWT, NICHIA chips with independent intelligence property rights integrated single high power LED as the light source, utilize unique design of multi-chip integrated single-module light sources, adopt the imported high-brightness semiconductor chips; high strength tempered steel glass cover; high efficiency imported constant current source. Initially creating the integrative design for the heat sink and light housing. The LED is directly connected with the shell closely and the heat from LED will be removed effectively through the shell heat dissipation wing and the air convection which fully ensures 50000 hours life-span of LED street light. The service life can reach more than 11 years if counted according to 12 working hours per day. The maintenance cost is very low. The lamp shell adopts the aluminium alloy aluminium extrusion molding which can effectively eliminate the heat with waterproof and dustproof . The surface of the light has been treated with the anti-ultraviolet ray and anti-corrosion, the overall luminaire meets IP65 standard; Apply the design of monomer ellipse reflecting cavity with spherical cambered surface, it can specifically control the LED light within the required scope, and improve the uniformity and light energy utilization ratio of the lighting effect for the luminaires and it can highly reflect the energy-saving advantage of the LED street lights.. Compared with traditional sodium lamp, it can save electricity energy more than 75%. No harmful glare, No frequently flash. It can eliminate the dazzling, visual fatigue and sight disturbance aroused by traditional street light. It also can improve the safety of the...
