LED lighting market take-off should have three conditions

LED general lighting market to take off, must meet three basic conditions: first, each tile flux index to reach 150-180lm, the performance of current mass production of LED 100lm/W; second, every one thousand lumens of luminous flux of LED lighting market price to below $10, today's level is $30; third, LED lighting market penetration to reach 10%, penetration rate of only about 2% today.

Tong deputy general manager Jia Technology Marketing Center Zhang Shili (AndyChang) said: "I hereby estimated to be in 2013 or 2014 LED general lighting market can be called the first year of LED lighting. Moreover, commercial LED lighting, LED landscape lighting market must be more than the home LED lighting market first. "

Chinese, the United States, the European Union and Japan is currently the 4 major LED lighting market, and the family are in many TRIAC dimmer with low efficiency, China and Japan are not using TRIAC dimming, dimming so from 2015 to 2020 the mainstream will be PWM dimming. AndyChang believes that: the future trend of mainstream technology will be LED intelligent lighting, that is, according to the ambient light intensity automatically adjust the brightness of LED lamps. "

LED general lighting market today is still a pack melee situation, the main reason is that the market is not big enough, so GE, PHILPS and OSRAM now will actively promote the LED lighting market, fluorescent lamp market because they want to protect the existing still higher profit margins. AndyChang said: "GE, PHILPS and OSRAM are currently in the LED lighting market will only take the following strategies, not to walk in front of others, is estimated to be 2013 or 2014, they will more actively participate. But it is estimated that by 2015, the proportion of LED lighting they produce will not exceed 20% of the total output. "

GE, PHILPS and OSRAM should be less likely to continue to monopolize the LED lighting market, they can monopolize the traditional lighting lamps (incandescent lamp, fluorescent lamp and energy-saving lamp) to supply the market, because they have a distribution channel. But LED lighting market is different, the traditional IT vendors also have the opportunity to become a key enabler. For example, Samsung and LG will certainly grow up in the LED lighting market in the future.

In LED lighting driver, AndyChang said: "I think the future of non isolated single-stage drive power LED lighting will be the mainstream, because the non isolation structure is the simplest, lowest cost BOM. Two level architecture LED lighting drive power is large, the cost is not low, although the two level architecture helps to remove the output capacitor. "
