Long life or the LED industry into the grave?

China LED Reuters] my family has a LED lamp installed in 2010, not bad, I can still use a ten year old in. "A consumer half jokingly said that he wanted to change the lights can not find an excuse.

LED long life for the vast number of consumers is undoubtedly a great gospel". However, for LED companies, the problem has come, the industry has suggested that the LED lamp is too durable, not bad, so go on demand come from? In the end how much? "

Contradiction lies

At present, LED lamp, LED bulb lamp etc. the service life of the nominal not one, 15000 hours, 25000 hours, 3 hours per day is calculated if you use, the service life is 15000 hours of lamp can be used for 13.7 years (lamp life 25000 hours can be used for 22.8 years), if in accordance with the use of 10 hours every day the calculation, then the service life of lamps for 15000 hours can be used for 4.1 years (lamp life 25000 hours can be used for 6.85 years). Regardless of all kinds of the LED lamps produced by enterprises are in use life of this parameter are the virtual target problem, many industry insiders have realized that "long life" once the advantage now seems to become LED's weakness".

"There's a reason to worry. BYD lighting sales director Xiao Zhiyong said that life is too long will lead to smaller and smaller market. Now on the market in more than 20 thousand companies, to the end may be only a few hundred. "But then again, when we chose to do LED, everyone's original intention in addition to promising market prospects, there is also part of the reason is because it is green. "

"This is really a problem. Once focused on packaging, and now gradually transformation of lighting applications, said Wang Peng, deputy general manager of lion light, if the LED lamps using the best components, then the life of 30 thousand hours is possible. "Long life is its selling point, but the long life of the low conversion rate, which is a contradiction. "

Wang Peng also mentioned that now Japan has the above problems. The replacement of a lot of LED lights really make the Japanese market unpopular for a while. "The quality of the Japanese market is particularly high, for a long time to have a new demand, in fact, I think the Japanese LED lighting shipments have been shrinking. "

Basically is a change, one less, the potential market is smaller. An industry analyst who declined to be named deeply worried that the market cake is so big, eat a piece, and so on ten years to eat another piece of the next eight years, perhaps the enterprise has long been starved to death.

Wang Fei, a senior analyst at LEDinside, said the longevity of the industry will become the epitaph. Every sale of a piece of light means that the market is cut off a piece of cake. This may also prove from the side why so many LED companies in recent years closed down. "

Another way?

But the market is always optimistic. South China University of Technology professor Wen Shangsheng believes that if the LED as an electronic product to do, give it more personalized and innovative points, as a work of art, a pursuit, repeat purchase rate is no problem. "

Jia Wei shares vice president Liu Xiaoxiong believes that the industry can go to focus on some new technology. Including plant lighting, automotive lighting, visible light communication, which is a big market for LED applications. I believe that our market is very large, the LED market will have a lot of new areas waiting for mining. "

I think it is better to do their own positioning, the entire market capacity is very large, (take street lights) you see China's road has been widened, do not worry. Philips Lumileds Asia Pacific Marketing Director Zhou Xuejun said.

Say again, if the life of the LED lamp is really as high as the industry advocates? "Now because of the pressure of market competition, most enterprises will not be so high the life of the lamp, not to mention 30 thousand hours, can adhere to the 10 thousand hour is probably a minority. Wang Peng believes that the current market is not the best quality products, precisely in terms of performance and price and market matching products. Because of this, the longevity of the impact of the replacement rate for the Chinese market may not be so obvious. On the other hand, the current penetration of LED is not high, the market is still very broad. "

If we say that the current domestic market has been the emergence of this fear, I think it is actually caused by oversupply in the domestic market, the product can not be sold, but turned out to be something too durable. Zhejiang and Hui Lighting Technology Co., Ltd., executive vice president Ding Jianhua also believes that the current domestic market is not a large number of real long life products.

But Ding Jianhua said that the industry does need a plan to eliminate the cycle, long life need to have a critical point in the market, it is more conducive to the replacement of products and technology changes. For LED, the industry has also discussed, we believe that 2-5 will be more appropriate, some of the construction, professional lighting can be higher. "

Even if all the people in the LED long life will affect the market exchange rate of the complex problems showed different degrees of anxiety, but one thing is for sure. As Wang Fei said, although the LED industry is a long-term pressure on the growth of space, but this is precisely the LED can make a contribution to energy saving and environmental protection.
