Standard procurement market semiconductor lighting standards urgently needed

According to the semiconductor lighting as an important product of China's green lighting industry, its development has entered the initial stage, semiconductor lighting as the country's 863 key projects began to promote the country.

Government procurement to promote energy-saving lamp industry upgrade

Recently, the Ministry of industry and information technology have been introduced 9 semiconductor lighting device upstream of the national standard, and formally implemented in January next year. As for the national semiconductor lighting lamp standards, research China Electronics Standardization National Semiconductor Industry Alliance were coordinated by the Ministry of industry and information technology and the National Standardization Committee gradually promote lighting.

Geng Bo, director of the office of the National Semiconductor Industry Alliance, told reporters that the industry alliance has introduced the technical specifications of semiconductor lighting, including tunnel lights and street lamps two. But industry sources said, LED lighting in recent years due to large-scale procurement in government projects, but also need to introduce a unified national standard to regulate the market as soon as possible.

Upstream devices regulate the 9 criteria

The semiconductor lighting industry and Information Technology Department issued the 9 industry standards, mainly concentrated in the upstream industry, including power semiconductor optoelectronic devices, blank detail specification for semiconductor testing method, terminology, with GaN based sapphire substrate for semiconductor, semiconductor chip, power semiconductor chip specifications, test methods, small power semiconductor optoelectronic devices Blank detail specification for semiconductor product series spectrum. The establishment of these 9 standards, to improve the semiconductor lighting chips, devices, modules, components and drive circuit, control circuit, the standard system has played a significant role in regulating the market played a certain role in the protection.

China Institute of Electronic Technology Standardization Institute senior engineer Zhao Ying said that these 9 standards are developed independently, in some areas have a breakthrough. For example, in the standard of "semiconductor phosphor", it is proposed that the external quantum efficiency is used as the evaluation index to evaluate the luminous efficiency. In this test, the powder selection work is simplified, and the difficult problem of the luminous efficiency test has been solved for a long time.

At present, LED is mainly used in the field of outdoor lighting, and mainly in the field of high-power lighting. According to the reporter, the radiation of large power lighting directly affects the life of the product, to test the heat, assessment of thermal design, power consumption, energy efficiency, these are the national standards of semiconductor lighting focus.

Calls for the introduction of the standard as soon as possible

Industry experts said that although the semiconductor standards in the upper reaches of the field has been a national standard, but more urgent is the need for the introduction of lighting standards. LED lighting industry development, whether domestic or foreign, LED lighting product quality certification has no strict standards, but also the lack of authoritative certification, which makes many manufacturers and buyers of its prohibitive.

China Electronic Chamber of Commerce Deputy Secretary General Lu Renbo told reporters that the support policy to the semiconductor lighting industry countries are all over the country to promote the standard of wildly beating gongs and drums, if not introduced, around the government procurement LED lamp also formed a barrier.

According to the reporter, the national government procurement center in the procurement of energy-saving lamps are in accordance with the relevant provisions of the state and the relevant standards for procurement, and require suppliers to be the national energy-saving products in 2009 to win the promotion of enterprises. For example, this year, the Shenyang municipal government procurement center of the 230 thousand energy-saving lamps procurement project will take a competitive negotiation procurement, evaluation method for the lowest bid price method. And marked for the country and the province to the relevant administrative departments of the "government procurement of independent innovation products catalog" of the tender products, the price should be 10% of its price deduction. For the country's relevant administrative departments issued the "government procurement list of energy-saving products" and "environmental labeling products, government procurement list" of the tender products, the price of its bid shall be given 5% of the price deduction. For the products at the same time belong to independent innovation products, energy saving products or environmental labeling products, the price should be 15% of its bid price deduction.

There is no national qualification testing agencies to LED product certification, but also makes it impossible for us to identify the quality of the product according to the national technical indicators. Zhejiang procurement center official said, at present, the quality of the procurement of products around the uneven, only from the purchase of energy-saving certification to measure. "

High cost is the bottleneck of development

The national "ten city lights" semiconductor lighting application project has been in the 21 city blossom everywhere, this is that LED first popularized in road lighting, according to the reporter, the entire campus of Tianjin University of Technology has installed nearly 5000 light semiconductor lighting lamp; high tech Zone of Dalian City, near 50 Street Road 200 thousand meters long road will be the LED street lighting, Shenzhen Shekou Industrial Zone within the red line of the lamps will replace all energy-saving LED lights, Nanchang city in 2011 to promote LED street lamp 18 thousand.

Why spare no effort to use semiconductor lighting products throughout the country? This is mainly because the LED lamp has advantage in technology, it has no flicker, no UV, no harm to human characteristics, more importantly, energy-saving lamps than incandescent lamp energy saving 4/5, while LED energy-saving lamps such 1/4, this is LED in energy saving technology breakthrough.
