  • What’s the high power LED?
  • 12-10-2013

High power LED is a light emitting diode with high rated current. Low LED power is generally 0.1W, operating current is 20mA, but the high power LED can reach 1W, 2W, or even tens of watts, operating current can be ranged from tens of mA to several hundred mA. Generally, high-power LED light source is a single LED power higher than 0.5W.


At present, many manufacturers use low power LED, but it needs use a lot of LED, and also lower power LED with higher light decay. So it trends to use high power LED source in commercial lighting.


High-power LED as the light source with features of low power consumption, less heating, long life, fast response, good direction and so on. Housing is available for PC pipe, able to bear high temperature of 135 degrees, low temperature of -45 degrees.


But currently the high-power LED light conversion efficiency is still low, and cost is high, which decides it’s mainly used in some special lighting areas like oilfield, petrochemical, railway, mining, military and other industries. But in the long term, the high power LED will be more and more popular in general lighting due to its advantages and we believe with the technology development, some bottleneck of the high power LED will be broken.
