Chongqing breaks through LED home technology
The LED lighting technology refers to a technology that utilizes the light-emitting characteristics of a semiconductor material to fabricate a semiconductor light-emitting diode (ie, LED) suitable for illumination and a lamp for application thereof.
"The incandescent lamp has congenital defects from the day it came out, the tungsten wire heating consumes a large amount of electricity, the bulb is fragile and consumes a large amount of energy, and it is easy to get an electric shock." Xu Zhipeng, deputy director of the Municipal Science and Technology Commission, said that the ordinary light bulb It can only be used for about 1 year, but the LED has a life span of 10 years and is 80% more energy efficient than ordinary bulbs. According to the calculation of Chongqing's 34.4 million population, the annual electricity consumption is over 100 million degrees, which is more than 60 million yuan according to 0.6 yuan per kilowatt-hour. If LED household lamps are used, it will save 48 million yuan.
Because LED light source has the advantages of energy saving, long life, environmental protection, rich volume and filial color, it is known as “the future of lighting technologyâ€. The person in charge of the Municipal Science and Technology Commission introduced that at present, the city has developed high-power white LED household lamps, which will increase the conversion rate of electric energy to 80%, which is at the leading level in China.
The future international market has great potential
Authoritative forecasts that semiconductor lighting will replace existing traditional light sources in the next 5-10 years.
"Future white LEDs will be cheaper and the overall market capacity will grow rapidly." Xu Zhipeng optimistically pointed out that according to the US Department of Energy, around 2010, 55% of incandescent lamps and fluorescent lamps in the United States will be replaced by LEDs, which may form a 50 billion. The big industry of the dollar. And Japan proposed that LED will replace traditional incandescent lamps on a large scale this year. Japan, the United States, Europe, South Korea and other countries have officially launched the LED lighting strategic plan.
Faced with the rapid rise of the LED lighting industry and the rapid growth of high-tech industries, Chongqing is “heart-movingâ€.
Western industrial base is ready to go
"The city's home LED is scheduled to be put into production next year." Xu Zhipeng said that in order to seize the commanding heights of the LED market in the future, within two to three years, the city will focus on household LEDs and continue to cultivate one or two core competencies. Leading enterprises, and spawn a group of affiliated enterprises, forming a group of enterprises with leading enterprises as the core; by 2010, the LED luminous efficiency will be further increased by 5 times, and the price will be reduced by 50%. The initial establishment is based on application technology development and product manufacturing. The main western LED industry base.
