LED: small bulb industry

Currently, the high price of LED so that ordinary consumers prohibitive. However, the speed of its development is to improve the luminous efficiency of 50% every 18 months, the cost decreased by 1 times. Upstream chip research and development of new technologies, will eliminate LED into the biggest obstacle to the cost of general lighting.

How much energy saving effect? Power saving 80%

January 25th, in Tianjin Binhai New Area, Tanggu, Bohai building materials City, is being renovated Li Xiang looking for energy-saving lamps. "I heard that LED (semiconductor lighting) very power-saving. So I'm looking for something. "But Li Xiang didn't find it. "I'm disappointed, I don't know when the lights are on the market. "Is LED more energy efficient? Tianjin Central Electronic Information Group Co., Ltd. chief engineer Qin Kejing said: "as a new concept of the solid-state light source, obviously the advantages of LED lighting, saving 80% more than incandescent lamp, mercury lamp, sodium lamp, saving more than 60% than. Because of its incomparable energy saving, environmental protection, longevity, controllability and other technical advantages, LED lighting has become one of the most promising new technologies in the world in recent years.

How to break the bottleneck? Upstream chip technology is the key

When to fly into the homes of ordinary people? Qin Kejing, currently in Tianjin, a large decorative city can not see this LED, but in the tooling market, LED has begun to use the. For now, energy saving, environmental protection is the biggest selling point of LED products, but its high price is prohibitive for ordinary consumers.

According to reports, the high cost of LED bulbs mainly from the LED control chip. At present, the general solution requires three control chips to control a LED light source. Due to the high cost of the chip, so the price of the end product than ordinary incandescent lamp, energy-saving lamps are expensive several times. Industrial chain is too long, resulting in a long product development cycle; due to the division of labor is not clear, large-scale manufacturing has not yet formed is also an important reason.

It is in this context, the central management of the group of careful consideration, the company decided in the headquarters of the group - TEDA district to create a LED (Microelectronics Semiconductor Lighting) industry base, bigger and stronger LED industry chain, to maximize the improvement of the industrial chain, raw materials, production, manufacturing, chip epitaxial device packaging applications and equipment supporting industries are starting or brewing. In the industry view, this approach can do to reduce costs and expand the market effect.

Industry experts hold optimistic forecasts. Li Jinmin, director of the Institute of semiconductors, Chinese Academy of Sciences, said the pace of development of semiconductor lighting is basically every 18 months luminous efficiency increased by 50%, the cost decreased by 1 times. That is, Moore's law, that is, with the development of science and technology, commodity performance will become better and better, and the price is getting cheaper.

The development of new technologies upstream chip, will greatly reduce the cost of production per unit of LED, thus eliminating the biggest obstacle to the cost of LED into ordinary lighting. Reasonable and effective government organizations, coupled with China's scientific research capabilities and enterprise base, fully able to achieve this goal.

In the central's Huaxiang Electronics Co. Ltd. production workshop, LED lighting company director Shao Kang said that the price of LED products is a lot more expensive than energy-saving lamps, but the product promotion is not only money, social responsibility is also very important. "A common household lamp about 400 yuan in the market, about twice as expensive than energy-saving lamps currently on the market to sell, but the service life of the LED lamp is relatively long, and cost saving, in general, two years to recover the cost of the increase. He said.

Future money scene? Low carbon business is very good

With the advent of the era of global low carbon economy, energy saving and emission reduction has become the core of economic development, LED lighting to replace traditional lighting will be just around the corner.

The latest statistics show that: in 2009, the number of street lights on the road lighting market in mainland China as high as 28 million, while the annual increase of about 300~400 lamps and replacement. If all of these lights are replaced by LED street lights, it will be a huge number. For the central group of such enterprises, such a market is clearly an endless digging jinshan.

In addition, some experts have considered such an account: if you use 10 watt energy-saving lamps to replace its brightness is close to 60 watt incandescent lamps, with the use of the country 1 billion 200 million, each energy-saving lamp every 4 hours lighting calculation, the annual savings of electricity equivalent to the Three Gorges hydropower station power total annual. If the country's existing ordinary incandescent lamps are all replaced by energy-saving lamps, the country can save about 60000000000 kwh a year, equivalent to the annual electricity consumption of a province in the central region.
