Taiwan University of Science and Technology develops new LED lamps to reduce the use of light bulbs by half

Associate Professor Li Hongbin from the Department of Materials Science and Engineering, Da-Yeh University, Taiwan, and Shengwei Optoelectronics Co., Ltd. have jointly developed new LED lamps, which are not only low glare, but also have good heat dissipation. The amount of light bulbs is only half, and the related technology has been subsidized by the Ministry of Science and Technology. And through the patent application. ▲Daiye University develops new LEDs. As long as half of the materials are used by Associate Professor Li Hongbin, they use the design of tilt and reflection to make the LED light reflect through the aluminum plate as a fog light source. The brightness is the same as the traditional, but the light is softer and improved. Glare and glare problems. The LED arrangement of this new type of lamp is not as tight as in the past, which can reduce the use of one-half of the light bulb. It is not only more environmentally friendly, but also increases the distance between the bulbs, which makes the heat-conducting area larger, and the heat dissipation effect is better, which can reduce the LED loss caused by high temperature. To extend the life of the lamp. ▲ Associate Professor Li Hongbin (China) and Dawei Optoelectronics Co., Ltd. cooperated with Shengwei Optoelectronics Co., Ltd. to develop new LED lamps. Associate Professor Li Hongbin said that the current T5/T8 daylight lamps, which account for a large number of indoor lighting, have gradually been replaced by white LED lamps. There are two main types of LED lighting fixtures, one is LED panel light. However, the cost of commercially available LED panel lamps is high and the promotion is not easy. The other is to replace the LED light bar, which can be directly parallel with the traditional fluorescent tube, and the price is moderate. It is the main product at present, and is also the main product of Shengwei Optoelectronics, the cooperation partner of the plan. ▲Deputy Professor Li Hongbin from the Department of Materials of Da Ye University (left) introduces the difference between the new LED lamps and traditional lamps. Huang Liangxi, a master student involved in research and development, said that poor heat dissipation will increase the temperature of the lamps, resulting in lower LED die efficiency and early deterioration of phosphors. . The new LED developed by the laboratory improves the LED heat dissipation problem through the application of nano-array anode aluminum oxide (NAAAO) technology. Li Suer, a senior, said that when the optical test was carried out, they found that the aluminum substrate used for the pedestal was directional, and the LED light source was therefore uneven. It took three or four months before and after the test to successfully improve the problem through heat treatment. . It is possible to successfully complete research and development step by step, and it is very fulfilling. I look forward to seeing the R&D results listed soon.
