The number of Duodawa LED street is equivalent to the number of Duodawa high pressure sodium lamp?
Reference room lightingLED street lamp with the conventional high-pressure sodium street lamp is different, the light source of high power LED lamp with low voltage DC power supply, by the synthesis of GaN based blue LED and yellow fluorescent powder, white LED, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in city road lighting. The outer cover can be made of PC tube, high temperature resistance up to 135 degrees, low temperature resistance up to -45 degrees.
The LED driver can easily do more than 90%, and the circuit is simple and stable. But since LED is cold light source, the electrical energy into heat 90%, is not easy to solve the heat radiator, such as LED >700W lamp than high-pressure sodium lamp radiator 700W is much larger.
The reason for power saving is the efficiency of the drive circuit and the power factorThe driving force of high pressure sodium lamp is inductive and electronic. The efficiency of inductance is less than 60%, and the efficiency of electronic is less than 80%. It is a thermal light source, which can radiate heat
