1.Light Source  It uses high power LED light source chips, which is currently the best abroad as well as with the highest lumens. In addition, it adopts the advanced eutectic welding & die bond craft work and particular process of phosphor coating to have a small luminance decrease and long service life. 2.Heat Dissipation  It adopts dual heat dissipation technology by cooling fins and heat radiating chambers, which are with aluminum die casting cover. This decreases the temperature of high power LED. In addition, driving power and lamps are installed separately to reduce the extra temperature-rise of lanterns and have a convenient maintenance.3.Service Life  The luminance decrease is less than 1% within 5000 hours and LED working life is more than 50000 hours.4.Luminous Efficiency  It adopts the best chips of BRIDGELUX, CREE and EPISTSR, but no lens and reflector. LED light directly projects on the road, reducing the light loss of secondary optical design 5.Energy-Saving  The luminosity of LED street lamp with the same power is around 3 times of traditional sodium light, saving more than 70% energy.6.Environmental ProtectionHazardous substance should not be included, such as halogen, lead, mercury. Also, it should not cause pollutions to environment and has to meet CE & ROHS standards. 7.Application  It is widely used for the lighting of major road, secondary road in cities as well as community roads.
