In a variety
of energy-saving and high efficiency light sources, LED has been the
focus of attention for all people. LED technology, in particular the
rapid growth in recent years, the past five years, the efficiency of
LED light-emitting compound annual growth rate of 56%, commercial white
LED luminous efficiency reached 100lm / W. On the other hand,
technology promotion, with substantial expansion of Asian countries,
making rapid decline in unit price LED products. Estimates that, as
governments and manufacturers LED R & D resources for investment in
2015 LED luminous efficiency will reach 188lm / W, far more than the
existing light source technologies, the cost can be significantly down
to only two U.S. dollars per thousand lumens a new low. |
