Semiconductor lighting blows into the general lighting market horn
On the way of semiconductor lighting into the family, the technological gap between China's upstream chips and lighting materials has become an important part of the development of the entire industry chain.
A new way of lighting is approaching our lives, this is semiconductor lighting. When semiconductor lighting has been widely used in traffic lights, electronic screens, landscape lighting, etc., it has now blew its horn into the general lighting market.
At the China International Semiconductor Lighting Forum and Exhibition held in Shanghai at the end of August this year, Shi Hancan, general manager of Hong Kong Huagang Optoelectronics Group Co., Ltd. summarized this trend: "In 2007, there was a significant change in the semiconductor lighting industry. It is from the special application field to the field of civil lighting."
At present, the United States GE, the Netherlands Philips, Germany Osram three world lighting production giants have cooperated with semiconductor companies to form a semiconductor lighting company to seize the industrial commanding heights. The US Department of Energy research report suggests that in 2010, 55% of incandescent and fluorescent lamps in the United States will be replaced by semiconductor lamps. Some experts believe that by 2010, semiconductor lighting is expected to exceed fluorescent lamps and directly enter the general lighting field, which accounts for 15% to 20% of global power consumption.
In the view of Li Jintao, director of the Institute of Semiconductors of the Chinese Academy of Sciences, in the country, the output value of the semiconductor lighting industry is expected to reach 100 billion yuan in 2010. Chen Lianghui, an academician of the Chinese Academy of Engineering, calculated this account. "If semiconductor lighting enters one-third of the lighting market in 2010, it can save 30% of electricity, that is, 100 billion kWh of electricity, which is equivalent to at least one power generation of the Three Gorges Project. the amount."
This prospect is very attractive.
Three or five years or ten years?
Semiconductor lighting is so favored because of its unique advantages: high efficiency, energy saving, environmental protection, safety, long life...
If you walk on a road in Nanjing at night, you may find that the light on the headlights seems to be spiritual. It just covers the entire road and will not "overflow" the road, leaving no light. "shadow".
"This is semiconductor lighting, it will not cause light pollution or waste, generally incandescent lamps, fluorescent lamps can not do." Tsinghua University integrated optoelectronics laboratory director Luo Yi told reporters. Now, Tsinghua University is ready to use semiconductor lighting on campus lights. Today, street lighting in some cities in the south and the Pearl River Delta region is the semiconductor lighting product.
If you use this lighting method for your home, you may not see any fixtures, but only a ceiling that will illuminate, you can adjust the lighting source with the morning, noon, and nighttime changes, so that the indoor light environment is close to the moon and stars. Natural light such as the sun. When adjusting to the "star" state, the light inside the house is awkward. In the "moon" state, the interior is filled with cold "moon" light. In the "sun" state, the interior is exactly the same as the white.
