LED lighting industry
100-200 dollars a LED light bulb, you buy it? China LED street lamp shapes, there is no uniform industry standard, not only to the user caused by maintenance problems, and when the fight was no criteria to guide state subsidies ... ... hot as a hot new industry, the growth process has faced trouble. Yesterday, in the "China LED light 2010 trip to China, Nanjing Conference", attended by executives, experts on the development of LED lighting industry, the bottleneck was the "cool thinking."
Launched a broad market is slowly
LED semiconductor lighting means in Chinese, is a chip to control the light of new lighting technology is the focus of the development of the city to establish new industries. The industry was predicted that mankind has experienced kerosene lighting in, incandescent, fluorescent phase, and will enter the semiconductor lighting era.
On daily life with the LED had inadvertently touch on the small to electronic watches, cell phones, electronic calculators and credit card machine display, large Olympic Water Cube, theme of the Expo Hall of the Landscape, can see the LED's figure. Career Tang Guoqing, general manager, said the Chinese market in 2008, their company 496 000 LED lights lit the Olympic Games Water Cube, the LED lamp has lit up this year, the theme of the Expo Hall.
Early last year, the State Science and Technology launched the "10 City, 10000," Model Cities Programme semiconductor lighting applications, and vigorously promote the LED lights. Next year China will build in 50 cities 2 million LED lamps, a huge market is to start slowly.
High cost, lack of standards hindered industrial development
But as a new industry, growth is not a smooth road, the biggest worry is the high cost. Radio and Television Company Ltd. in Suzhou Nanocrystalline Liangbing Wen admitted that a LED light bulbs offer for 100-200 yuan, the Chinese people clearly have no spending power. Behind the high price is the lack of core technology. 60% of the cost of LED lamps in China focused on the chip, but do not have core technology, the basic by our LED 芯片 from the United States, Japan, Germany, South Korea, import, Zhi Shi LED 灯具 high prices.
LED companies even more embarrassing is that, when other types of energy-saving products often enjoy government subsidies, LED industry has introduced the industry because there is no national standard, even if the Government would like to send subsidies are no criteria to guide. Moreover, the standard LED's absence also allows users a headache. Chief Engineer of Nanjing street management, said Liu Lei fact, because the manufacturers of LED light in a shape different, there are well-round, maintenance tools, materials not universal, to the maintenance of great trouble. Repair street light, with three tools to be enough, but repair LED lights, too small truck to go, put a pile of materials and tools.
Subject to technical constraints, LED investments to pinpoint Road
Optimistic about LED industry, now Foxconn, Hisense, music and other large enterprises have been involved in US-LED market, many real estate agents have their money in.. But yesterday's workshop, it was that, because of technical bottlenecks, LED does not apply to all areas of investment necessary to identify the road.
Liu Lei fact that, LED landscape lighting has unique advantages, small size, design flexibility, can be any combination. Landscape lighting, light a small bridge, some local designers have to use 3W, and some may take 4W, and some even use 3.5W of, LED are met, the current can not do other light sources this. Other light bulbs to make the color effect, color coating to the bulb inside, and the LED itself is a colored light source, it will issue its own color of light. LED as a light, backlight, the outlook is not bad.
However, he considered that as high-power LED thermal problems are not resolved, energy-saving incomplete, and there is uniform color temperature and other issues, the LED street lamps to be used as functional lighting, technically there is still a way to go.
