Overview of LED industry standardization The energy-saving and environmentfriendly features of the LED technology provide anticipated solutions to completely break through the high energy consumption dilemma in human illumination. Over the past decade, the LED industry has grown remarkably, reflected by the increase of the photoelectric conversion efficiency for LED from around 201m/W in 2003 to 1301m/W in 2013. A complete industry chain has come into being globally, ranging from the upstream chip production to the encapsulating in the middle and the downstream LED applications. Those time-cherished multinationals （e.g. Philips, OSRAM, CREE） in the lighting industry also accomplished the recombination and transformation toward the LED technologies.
