University of new research and development of LED bulbs more than half the amount of environmental protection

"Da-YehUniversity" School of materials science and engineering professor Li Hongbin Shengwei photoelectric company in cooperation with the development of new LED lamps, not only low glare, good heat and light dosage as long as half, technologies of Ministry of science and technology subsidies, and through the patent application.

Li Hongbin, associate professor of the Department of materials, pointed out that they use the tilt and reflection design, so that the LED light through the aluminum plate reflects a fog like light source, the same brightness and the traditional, but the light is soft, improved glare and glare problems. The new LED lamps arranged than in the past so close, it can reduce 1/2 of the lighting usage, not only more environmental protection, expand the bulb also let the heat area spacing becomes larger, better heat dissipation, can reduce the loss caused by the high temperature LED, prolong the service life of lamps.

Li Hongbin, associate professor, said the current account for the bulk of indoor lighting T5/T8 fluorescent lamps, has gradually been replaced by white LED lamps trend. The existing LED lighting lamps are mainly two kinds, one is the LED flat lamp, but the cost of selling LED flat lamp high, not easy to promote. The other is the replacement of the LED lamp, can be directly in line with the traditional fluorescent lamp, the price is moderate, the main products for the current, but also the main product of the Project Co manufacturers Sheng photoelectric.

Huang Liangjun, a graduate student involved in research and development, said the poor heat radiation will increase the temperature of the lamp, resulting in the decline in the effectiveness of LED grain, phosphor powder early deterioration and other shortcomings. LED developed by the laboratory, through the use of LED (nano-array anodic aluminum, NAAAO) technology to improve the heat dissipation problem.

Senior Li Suer said optical test, they found that used when the aluminum substrate base with direction, so the LED light source is not uniform, and try for three or four months, only through the heat treatment to improve the problem of success. Step by step to successfully complete the research and development, a sense of accomplishment, look forward to see the results of the research can be seen as soon as possible.
