LED home lighting lighting has a bright future

Today, the use of LED lights is becoming more and more widespread, not only in urban construction, but also in home decoration. It is reported that in August this year, the Ministry of Science and Technology released the “12th Five-Year Plan” for the development of semiconductor lighting technology. By 2015, the scale of China’s semiconductor lighting industry will reach 500 billion yuan, and the cost of LED lighting products will be reduced to 2011. 1/5, the share in the general lighting market should reach 30%. It can be foreseen that more and more LED lights will be used in home decoration and interior decoration. In the future development, LED will become the main force of the lighting industry.

LED has technical advantages

Although the current mainstream of the lighting market is the fluorescent lamp, which saves about 75% of energy than incandescent lamps, the service life is still limited, generally not exceeding 10,000 hours. Moreover, the environmental pollution caused by metallic mercury in fluorescent lamps is also a problem that cannot be solved. However, LED lighting energy-saving lamps in the market have far exceeded fluorescent lamps in energy consumption, longevity and environmental protection. According to the person in charge of Shishi Tide Optoelectronics, "LED lamps have energy-saving efficiency, high luminous efficiency, low power consumption, long life, pure light color, high stability, safety, environmental protection and many other traditional light sources are not The superiority of comparison is a low-carbon, green, and environmentally-friendly lighting technology, and it is recognized as one of the most promising high-tech fields in the 21st century."

"To reach the brightness of a 100 watt incandescent lamp, the fluorescent lamp must be at least 25 watts, while the LED lamp only needs 10 watts, not to mention that the LED lamp life is five times that of the fluorescent lamp." said Xiao Zhang, a technician, "The price of a 10-watt LED lamp About 50 yuan, the same efficacy of the fluorescent lamp is priced at 25 yuan, it seems that the price is half the difference, but the energy cost savings are counted in, the difference between the higher prices can be recovered in two years."

For the rapid development of LED technology, people in the industry said that with the trend of better lighting products and lower product costs, LED lighting will usher in explosive growth in the future.

Incandescent light gradually exits the market

A few days ago, when the reporter visited the lighting market, he discovered that although the incandescent lamp market still has sales, it has been greatly reduced compared with the past. Fluorescent lamps and LED lamps have gradually become the protagonists of the lighting market.

“Although incandescent lamps are cheap, there are few people who buy them.” Mr. Li has been doing business for lamps and lanterns for some years. He admitted that incandescent lamps are very low in price, but their service life is not long and their energy-saving effect is poor. They have already reached the edge of elimination. Today, more and more people will choose fluorescent or LED lights. Talking about the sales status of incandescent lamps, Mr. Li said that many businesses have incandescent lamps in stock. Occasionally, customers will purchase them, mostly for factory lighting, and the most sold are incandescent lamps with a power of 60 watts and 100 watts or more.

According to industry sources, although incandescent lamps have already been labeled as "retired", they still have a certain market because of their low prices. With the deepening of the concept of environmental protection and energy conservation, energy saving lamps, long service life, cost-effective energy-saving lamps and LED lamps will cover the market in an all-round way, and incandescent lamps will not escape the fate of “delisting”.

The popularity of LED is a long way to go

Although there are a small number of home lighting companies in the market that have chosen LED as the light source, they have encountered a lot of barriers and are still in an imperfect period. It is reported that the independent innovation and patents in the LED field of China's enterprises are mainly concentrated in the encapsulation phase. In the most critical areas of white light, high-power LED lamp heat balance issues, long-lasting high-efficiency phosphors, etc., technology patents have been Europe, the United States, Japan, etc. State enterprise monopoly. The brightness, heat dissipation, luminous efficiency and uniformity, anti-static capability, anti-leakage capability and quality control level of domestic LED lighting fixtures are still far behind that of international products.

At the same time, in the current state of development of the industry, the high price threshold of LED lighting in the home field is definitely the biggest stumbling block for civilians. Ted Optoelectronics related personnel told reporters: "After years of development and technological improvements, the LED industry's cooling, driving, light sources, chips and other technologies have made great progress, coupled with people's income continues to improve and live The level is also changing, people are eager for energy-saving and environmental benefits brought about by LED products. This is the opportunity for LED to be used in home lighting."
