Photosynthetic efficiency competition has been the various manufacturers can't lose the war, CREE invincible in the lighting market is not only the success of its marketing strategy, more is the ability to constantly refresh record lighting technology (as shown in figure 1) for its customers continue to bring technical competitiveness. In 2012 between the vendor and try to overtake each other not easy, but a bigger gap. The emergence of the GaN epitaxial homogeneous, but also has the plan of corner overtaking on the brightness. While Taiwan factory ladies circle, but also claim that the whole lamp finished 230 lm/W lighting fate of records.

　　But although Seoul semiconductor release nPola single chip flux to 500 lm, but to the input power, how much has been cited but not fat, make its photosynthetic efficiency for the outside world a lot of reverie. And the substrate supplier mitsubishi become the customer of this product on his own initiative, is almost a self-marketing, the ambiguity is quite worth pondering. Expect 2013 Seoul can consumedly square square to unravel, let people see clearly GaN substrate true potential.

　　Previously unknown ladies in photosynthetic efficiency competition round, suddenly the palace-intrigue launched 230 lm/W chips, and after finished product claims still can maintain 230 lm/W of lighting. The whole lighting effect more than twice the average technical level, caused no small vibration industry. From the chip to the finished product, no loss, more similar to "perpetual motion machine" general against normal cognition. But ladies circle has always been a bit cagey about exactly technical details, the outside world can't searching the concrete implementation method. And with ladies circle in the industry status, also not be concocted news at random to make the eye. So the mystery, I'm afraid to solve until 2013, when is the ladies round "hidden" or "tease you play" will come out.

　　Photosynthetic efficiency between competition like martial-arts expert huashan mountain, although everyone knows that the first name, who can win who eventually rely on is the competition of comprehensive strength, but in order to get the place is still each exhibition to, even given their top weapons can sneak spectrum is a glorious thing. 2013 competition will also continue to light efficiency, the race of the just beginning, who can finally won the river's lake?
