LED lighting industry suffered growing pains"

A LED bulb 100 - 200 yuan, you can buy? LED lights and shapes, there is no uniform industry standard, not only caused the maintenance trouble to the user, but also in the struggle for national subsidies can not standard...... As a hot new industry, its growth process is facing all kinds of trouble. Yesterday, in the 2010 LED lighting China tour Nanjing seminar, the participating business executives, experts on the development of LED lighting industry bottlenecks were cold thinking".

A broad market is slowly unfolding

LED is a semiconductor lighting in China, is a new technology to control the use of light-emitting light-emitting chips, but also to establish the focus of the development of emerging industries. Some people in the industry predicted that the human lighting in the kerosene lamp, incandescent lamp, fluorescent lamp stage, the future will enter the era of semiconductor lighting.

People inadvertently in normal life as with LED contact, small electronic watches, mobile phone, electronic calculator and card machine display, landscape lamp to Olympic Water Cube, World Expo Museum, you can see the figure of LED. Tang Guoqing, general manager of CREE China market, said that in 2008 after their 496 thousand LED lights lit the Olympic Water Cube, this year, LED lights and lit the theme of the World Expo pavilion.

At the beginning of last year, the State Ministry of science and technology has launched the "Ten City million" semiconductor lighting application demonstration city program, and vigorously promote the LED lamp. Next year, China will build 2 million LED lights in the 50 cities, a huge market is slowly expanding.

High prices, lack of standards hinder the development of the industry

However, as an emerging industry, the growth path is not smooth, the biggest worry is the high cost. Suzhou crystal radio and Television Co., Ltd. chairman Liang Bingwen admitted that a LED bulb price 100 - 200 yuan, the Chinese people apparently do not have the ability to consume. Behind the high price is the lack of core technology. The cost of 60% LED lamps on the chip, but because we do not grasp the core technology, China's LED chip based on imports from the United States, Japan, Germany, Korea and other places, resulting in high prices of LED lamps.

LED companies even more embarrassing is that when other types of energy-saving products to enjoy government subsidies, the LED industry is not because of the introduction of national standards for the industry, even if the government wants to send subsidies, there is no standard basis. Not only that, but also let users of the standard LED headache. Nanjing Street Management Office chief engineer Liu Lei said, due to the manufacturers of different LED lights, a round well, maintenance tools, materials are not universal, to repair a lot of trouble. It is enough to repair an ordinary street lamp with three tools, but to repair the LED lights, you have to drive a small truck, carrying a pile of materials and tools.

By technical constraints, LED investment to identify the road

Optimistic about the LED industry, now Foxconn, Hisense, trimetazidine and other large enterprises have to intervene in the LED market, many real estate developers also put money into the. But yesterday's seminar, it was felt that due to technical bottlenecks, LED does not apply to all areas, investment to identify the road.

Liu Leishi believes that LED has unique advantages in landscape lighting, small size, flexible design, can be arbitrary combination. Landscape lighting, exposure to a small bridge, some designers may want to use 3W, and some may want to use 4W, and some even use 3.5W, LED can be achieved, the other light can not do this. Other bulbs to make color effects, to be painted inside the light bulb, and LED itself is a colored light source, they will issue a color light. LED used as indicator lights, backlight, good prospects.

However, he believes that due to the problem of high power LED heat is not resolved, energy saving is not complete, and the existence of uneven color temperature and other issues, so LED want to be used as street lamps and other functional lighting, there is still some way to go.
