New energy-saving light source LED fake Shanghai dress up day and night

Xinhuanet.com Shanghai channel reporter Wang Yu reported in October 6th from the Bund to the East China Sea Bridge to Wujiaochang, from the Oriental Pearl egg, called a "light emitting diode (LED)" a new type of light source, fully display its special such talent, alternative energy-saving neon lamp 70%, instead of 80% energy-saving incandescent lamp, more and more by the city landscape lighting field favored.

On the oriental pearl ball made in Japan 200W incandescent lamp as a light source, using LED light source, each light power consumption is only 70W, and the transformation of control system and other flood lamp, preliminary estimates than the original save nearly 75% of electricity consumption.

The LED semiconductor lighting filament, is a semiconductor chip for solid-state light source materials. It is the use of electronic moving to light, the direct conversion of electric energy into light energy, conversion efficiency of up to 68%, incandescent lamp is more than 5 times, the service life of incandescent lamp is 100 times. It is estimated that if 1/3 of the country's traditional lighting with LED replacement, the annual output of a Three Gorges Hydropower station.

Semiconductor lighting after Edison invented the light bulb, and a landmark leap, a light source is a revolution in the whole world, the global semiconductor lighting industry to seize the commanding heights of acceleration. China promulgated the "national long-term science and technology development plan", "energy efficient, long-life semiconductor lighting products" has been included in the first area of focus (energy) the first priority theme (industrial energy).

As one of the five national semiconductor lighting industrial base, Shanghai has initially formed a relatively complete industrial chain of LED, formed to Zhangjiang hi tech park as the core, green lighting group Songjiang, radiation Jiading, Yangpu and other areas of industry. As of the end of last year, Shanghai has 105 LED related patents, the development of more than 100 national standards, industry standards optical industry.

Reporter from the Shanghai Municipal Science and Technology Commission was informed that, by 2010, Shanghai's landscape and public lighting will be composed of new LED light source to play a leading role, then the largest year is expected to save 1 billion kwh of electricity, electricity is equivalent to a small city a year lighting.
