Hongkong HKUST scholars invented new bulbs can save 80% power

Electric light is a part of modern people's daily life can not or lack, but a long time to light up the lights cause energy waste. In the light emitting diode (LED) years of research on Professor Liu Jimei Department of electronic and computer engineering, University of science and technology, recently founder and LED lighting company, developed a new LED lighting, only 8W power can be issued is equivalent to the traditional tungsten 60W (lumen) eight hundred lumens of light flow, reduce the power of at least 80%. Liu said the new bulb is currently conducting the study of intelligent control, can use the mobile phone on the expected flow control lamp switch device.

This year's Nobel prize for physics awarded to the three Japanese scientists, Akasaki Yong, Tian Hao Hao and Nakamura Shuji, invented the high brightness blue LED, once again concerned about LED technology. Department of electronic and computer engineering professor Liu Jimei engaged in semiconductor research for many years, she pointed out that LED is a semiconductor electronic component capable of emitting light, as early as 1962 already appeared, but early only low luminosity red, until Nakamura Shuji et al blue LED, and combined with the green and red LED, produce seemingly white light.

But because of the traditional 60W incandescent light and fluorescent lamps is cheap, very popular in the market, but more heat generated by the power consumption is also higher. Liu Jimei and LED founder Wang Zhikang CLEDoS lighting company cooperation, developed a new LED bulb (airLED), only 8W can emit light flow equivalent to 60W incandescent light or 14W light bulbs eight hundred lumens, thus reducing the power eight to 90%.

To Hong Kong average power every zero point nine three yuan calculation, open four hours daily for 60W tungsten lamp, the annual electricity is about eighty-two yuan; the new LED lighting because only 8W, so even if the same day continuous open four hours, the annual electricity needs only about eleven yuan. Although the new LED lighting costs about fifty-five yuan, compared with incandescent light and fluorescent lamps is high, but the life of ten years.

Liu Jimei said that the new LED lighting research and development in recent years, compared with incandescent light, to achieve the "three low" effect, including low weight, low calorie, low volume and no mercury, "we use the standard lamp mode, but the lamp body with plastic instead of metal, and with light cover, make the new light bulb is the use of direct current, at the same time with air as heat, heat and volume weight, do three than incandescent light is low. "

Looking to the future, Liu said that in recent years, mobile phones and other mobile devices are very common, is currently conducting intelligent control of the bulb, the future use of mobile devices to control the switch.

In addition to scientific research, Liu Yi led the students to make microelectronic integrated circuits, and has developed to a very mature stage, can be used to play micro film, is currently being interested in further development of manufacturers.
