LED lighting: Delicious pie is not easy to eat

For the field of LED lighting, by the end of last year, the Ministry of science and technology, the Ministry of Finance launched the Ten City million program, it is an attractive big cake. According to the plan, in 2010 to promote more than 300 thousand LED municipal lighting in 10-20 cities, a rough calculation, only 300 thousand LED lights is a large market of $1 billion 500 million. In the civilian market LED, insiders predict that there are at least tens of billions of domestic market.

However, in an interview with reporters found that due to technical and price constraints, the current LED lighting market is far from large-scale launch, LED street lamp is still in the demonstration stage, the civil field is still only in the bud.

Reporters the day before from Shenzhen City Street Management Office learned that, recently, Shenzhen city for science and technology park road lamp replacement transformation, plans to install more than and 200 LED lights, there are more than and 20 foreign and local brands for bidding.

This is the first year since the purchase of LED street lamps in Shenzhen, this year, the Shenzhen SAR will purchase more than 2 thousand lights, coupled with the amount of procurement outside the customs clearance, it is estimated that the city will purchase 3000-4000 LED street lamp. Compared with the current city of Shenzhen about 20-30 million street lamps to maintain the amount of comparison, this procurement is obviously just a drop in the bucket.

According to the director of the planning and design of Shenzhen City Chamber Street Management Office Wu Chunhai introduction, from the beginning of 2006, Shenzhen branch began in some sections of the trial LED lights, but some small power chip lamps with less than a year on the bad, LED lights begin to high-power chip from 2008, the quality is relatively stable. Energy saving effect can reach 30-50%.

It is reported that Shenzhen currently has 10 in the road to try LED lights, which has about 1/4 enterprises submitted to the trial, and the trial of Guangming district government more than 2 thousand LED road lamps, half of the enterprise.

Involved in the enterprise too much, good and bad are coming in, it is very difficult to do quality control. Wu Chunhai said that the results of their tests show that in the LED street lamp, the current domestic products in terms of light distribution with foreign brands or a certain gap. "We selected 27 companies of products, after a year of trial operation, the proportion of the problem is probably 15-20%, mainly the product itself. "

For this result, Wu Chunhai believes that fairly satisfactory". As for the LED lamp life of up to 10 years of this argument, Wu said that because the trial time is short, still unable to judge. However, he believes that although the quality of the LED street lamp has improved, but the technology is still not mature enough, which is one of the reasons for the government is not determined to promote large-scale, in addition, the high price is also a factor.

Reporters from Shenzhen is located in North Huaqiang electronic world LED international trading center, a 5W spherical incandescent lamp LED lamp can replace 40W, but its price is 50 times of incandescent lamp, LED lamp is 20 times the price of the fluorescent lamp; a lamp and LED lamp 100W can replace high pressure sodium lamp at present, the widely used 200W, high pressure sodium lamp price is about 10001900 yuan / lamp, but LED lights to 5000-6000 yuan / lamp.

Wu Chunhai said that Shenzhen's LED tender will not only consider the price, at present, in the case of limited technology, only the price to ensure quality. "

A factor restricting the price of the LED lamp is the chip, only the chip on the cost of 30-40%, another reason is not enough production. "A sales manager allring technology told reporters that the current chip supply has not meet the market demand, domestic chip technology is not up to the brightness, can not be reached, the company is mainly using imported chips.

However, with the increase in the number of applications into the LED and the production of the product, the price of the last two years, LED lights have dropped rapidly. Allegedly, the market price of LED lights are more than 30% annual rate of decline.

Due to the municipal LED street lighting and civilian lighting market is not large-scale start, many companies have turned their attention to more practical landscape lighting, office lighting, shopping malls and other commercial lighting lighting. Due to the commercial lighting is more consideration of environmental protection, energy saving, light efficiency and other factors, so that more can be recognized by the market.

Although the LED mall lighting is still in the start-up phase, many companies have taken a fancy to this market and has begun to advance layout.

"For the LED industry, the next 5 years will be a very big change in the past 5 years, because of technical problems affecting the cost, and thus the cost of technological breakthroughs can be significantly reduced, and access to civilian. "Shenzhen LED International Trading Center Operations Manager Hu Juan said.
