Green lighting LED lights up future life
It is no longer an illusion to use only one lamp in a lifetime. The LED lamp that consumes only 10% of the incandescent lamp will become the mainstream lighting device in the world within 10 years with 80%~90% luminous efficiency and 100,000 hours of service life. Illuminating a market with more than $4.3 billion in lighting
In the Beijing Olympic Park, 440,000 Xlamp LED lights light up the water cube of nearly 80,000 square meters, and its total energy consumption is only 52% of the traditional lighting system, which makes the water cube become the technology Olympics and green. One of the symbols of the Olympics. On November 1, 2007, Cree, Inc., which produces XlampLED, replaced all lighting equipment at its headquarters and manufacturing facilities in North Carolina with LEDs, demonstrating the dual advantages of LED lights developed in terms of lighting performance and environmental protection. . LED lighting equipment that combines energy saving, environmental protection and low maintenance costs is a true alternative to traditional lighting solutions. In the eyes of Cree's president, starting with the Water Cube, the future world will be illuminated by LED lights.
An LED (light emitting diode) is a semiconductor that converts electrical energy into visible light. It uses electric field illumination to change the principle of incandescent light. Incandescent lamps convert most of the electrical energy into heat through the tungsten wire, and only 10% is converted into light energy. The spectrum of LEDs is almost entirely concentrated in the visible light range, and the luminous efficiency can reach 80% to 90%, and the heat released is much lower than other lighting systems. When the same intensity of light is emitted, the LED consumes only 10% of the incandescent light and 50% of the fluorescent light.
In theory, the longest life of LED lights can reach 100,000 hours, which is considered to be a single lamp for a lifetime.

According to a survey conducted by the China Green Lighting Project Promotion Project Office, China's annual lighting power consumption is more than 300 billion kWh. If LEDs are used to replace all incandescent lamps and some fluorescent lamps, it will save 1/3 of the lighting power. This is equivalent to the annual power generation of the Three Gorges Project, the world's largest power station.
At present, the Ministry of Science and Technology of China has approved Shanghai, Dalian, Nanchang, Xiamen and Shenzhen as LED industrialization bases. It is estimated that by 2010, the earliest approved LED industry in Xiamen will reach 20 billion yuan, and the whole of China will exceed 150 billion yuan.
