Experts for the Shenzhen semiconductor lighting industry bigger weapon

Newspaper reporter Yang Liuchun

Recently, the reporter in Fangda group interview, see a company using the special chip of semiconductor lighting lamp, which is composed of a few small grain size of a chip for daily lighting lamp light. It is noteworthy that this is based on LED semiconductor lighting technology behind the desk lamp, containing a huge industry.

Semiconductor lighting has a huge role in energy saving, according to experts predict that in 2005 to 2015, if the use of semiconductor lighting, the country can accumulate a total energy saving of 400 billion degrees, saving electricity costs of $260 billion. In order to accelerate the development of semiconductor lighting industry, more than 30 academicians submitted a joint report to the relevant departments of the State Council, the report pointed out that as long as the Three Gorges power station 5% investment into the semiconductor lighting R & D and production, promote green lighting, after 15 years of National Lighting Saving 100 billion degrees, the effect is equivalent to build a Three Gorges power engineering.

Because the semiconductor lighting has a huge market, so, this emerging industry is rapidly rising, the United States and Japan have formulated development plans, in order to seize the commanding heights of semiconductor lighting, China is also vigorously development of this industry, the increasingly fierce global competition.

Small tube technology market development

According to reports, Fanta this special chip using semiconductor lighting lamp, power consumption is only equivalent to the same brightness of ordinary lamps from 10% to 20%, its service life is 10 times longer than fluorescent lamps, 100 times longer than incandescent lamp, and its heat, no radiation, which belongs to the green a typical light source. Although, the lamp on the market price of about 500 yuan, but the user can count an "energy account": a 5 Watt LED lamp (equivalent to 40 watts of power ordinary lamp) every day if you use 5 hours a day, electricity savings of 0.17 yuan (calculated according to the price of 1 yuan per degree). A year can save electricity 62 yuan, down to 5 years will be able to save 310 yuan electricity, and the lamp life up to 50 thousand hours or more, count down, buy LED lamp is much more cost-effective than ordinary lamp.

In fact, LED desk lamp is one of the many semiconductor lighting products, people's daily use of mobile phones, computers, digital cameras, cars, there are semiconductor lighting figure. In the city landscape lighting, instrument indication, semiconductor lighting is widely used, for example, the Shanghai Oriental Pearl TV Tower in the night shining night decoration, are used in semiconductor lighting.

The reporter saw delightedly, last year the city's semiconductor lighting industry output value reached 8 billion yuan, and gathered more than and 300 companies, accounting for more than 70% of the total number of enterprises in the same industry, has been formed from the GaN based LED epitaxial wafer and chip, phosphor to the lighting engineering application product development of a complete industrial chain, the products are exported to the world around at home by Beijing, Shanghai and other city's favor, and mastered the core technology of semiconductor lighting wafer, chip manufacturing Fangda group is a leader in Shenzhen and even the whole country in the industry "".

Three major barriers to product development

However, the semiconductor lighting industry in Shenzhen is in a difficult climbing stage, the urgent need for government and community attention and support. During the interview, many companies told reporters that the semiconductor lighting products, although popular at home and abroad, but the promotion of Shenzhen is difficult. For example, the city landscape lighting project in Shenzhen rarely use LED products. According to the relevant departments of Shenzhen city lighting management center responsible person, the area is not LED, because the light irradiation effect caused by the LED lamp package is not good enough, and the packaging process, controller and other factors will affect the service life of the LED lamp, in addition, the high price of LED products.

So, what is the fundamental reason for the promotion of semiconductor lighting products difficult? Relevant experts believe that generally application must cross three "threshold": one is the price threshold, due to the high cost of R & D investment firms, resulting in LED products are expensive; the two is the concept of threshold, semiconductor lighting is a new industry, consumers lack an adequate understanding of it; the three is the technical threshold the use of new products in the consumer to bear certain risks, therefore, manufacturers should continuously improve the quality of semiconductor lighting products, so that consumers use them at ease.

Obviously, Shenzhen semiconductor lighting industry is in the stage of technology promotion, which is difficult to climb the stage. What is the enterprise to overcome their own difficulties, so that the industry slowly developed, or to help it, to promote the rapid expansion of the industry? Who will support this new energy saving industry rapidly bigger?

Yearn to support the emerging energy industry

Over the past 3 years, the annual increase in the city's power grid load capacity of about 1 million kilowatts, last year is a record high for the second time in a row, reaching 6 million 850 thousand kilowatts. If the lighting electricity accounted for 12% of electricity consumption, compared with ordinary semiconductor lighting lighting saving 80% - 90%, semiconductor lighting instead of ordinary lighting, Shenzhen currently only can reduce the electricity load of 66 740 thousand kilowatts, lighting electricity will be greatly decreased, and the electricity for lighting maintenance, replacement lamps etc. the cost will decrease sharply. In order to build "benefit Shenzhen", the promotion of energy saving technology and new products is more urgent.

Recently, the State Ministry of science and technology formally approved the construction of the national semiconductor lighting engineering industrialization base in Shenzhen, which is a major positive for the city's semiconductor lighting industry. So, how to take advantage of the rapid expansion of Dongfeng do
