LED: colorful lights "point" bright life

"My cell phone can be used as a flashlight!" At noon yesterday, the office of a high-tech enterprises in Optics Valley, Mr. Lin is showing off his new cell phone to colleagues, the night before the lights of our house corridor is broken, I was using it to open the door."

Originally, on the back of Mr. Lin's mobile phone with a special small light bulbs, high brightness, especially energy, is not easily broken, its name is LED chip.

A year out of the Three Gorges power station?

LED light-emitting diode, which uses solid semiconductor chip as luminescent materials, produce light at both ends under the effect of voltage. Compared with ordinary light bulb (tube), LED photoelectric conversion efficiency, long life, can save electricity 50%~80%. At present, LED is widely used in landscape lights, lights, traffic lights, outdoor display and other light-emitting devices.

In China in 2003 launched an emergency "national semiconductor lighting project". Optics Valley venture capital company in Wuhan is the first to do the LED industry investment Vc firm. Over the past two years, it has set up 3 production companies in Wuhan, Optics Valley, China, with the Hong Kong and Taiwan enterprises in cooperation with LED.

Recently, Wuhan Optics Valley Huacai Display Technology Co. Ltd. has just received an order: LED energy-saving lamp production can replace the cell lamp. Yesterday, Lin Bogang, general manager of the company to open a reporter just do a good job of energy-saving lamps, light dazzling. In fact, it is only 9 watts, can be used for 8~10 years (ordinary incandescent lamp is required at least 25 watts, generally have to change the light bulb for six months).

"If the existing street lamp for LED energy-saving lamp, a lamp can save 1000 yuan a year in electricity, the replacement cost does not include the maintenance fee and the artificial lighting." Lin Bogang said, China's lighting market, if there are 30% of the lights into the LED energy-saving lamps, the annual savings of a Three Gorges power plant."

Red orange yellow green

Optics Valley advanced optoelectronic corporate business sector director Chen Huiyun introduction, LED chip can directly emit red, yellow, blue, green, orange and purple seven colors, you can also enter program in the chip, it shows different patterns and colors.

"In the future all the incandescent lamp will be LED energy-saving lamp replacement." Lin Bogang describes a scene to reporters, "night in Hankou, is like entering a colorful fairy tale world. Jianghan Road pedestrian street is just like the day, all kinds of light beams from the old buildings gently slide......"
