lighting market to take off state. T8 Tube

 However, such lamps have a relatively troublesome drawback is that the color change in the  MR16 control circuit, which requires relatively high cost, but also the life of the drive circuit is a problem, the industry there are a number of solutions to cope with, it is expected that after 2009 class of applications will be more and more, in 2010 reached LED mood lighting market to take off state.

Cold light source: cold light source is the use of chemical energy, electrical energy, bio-energy excitation light (fireflies, neon, LED, etc.). Has a very excellent optical, variable flash features. Luminous object, its temperature is not higher than the ambient temperature is high, this luminescence is called as cold light source, such as LED is the use of electron-hole pair   LED Flexi recombination. Strictly speaking, LED light-emitting electroluminescent aurora is also heat generation, only relatively incandescent light source is a low point. LED optical conversion efficiency of 30%, and wherein the internal quantum efficiency of about 70% (close to the theoretical limit), the external quantum efficiency of about 50%. (This is only experimental data, not the exact value)
