Mr. Lu Ming, Group Manager of Materials and Construction Technology of ASTRI, specializes in optical diode (LED) technology for a new generation of solid-state lighting, electronic components, optoelectronic components and other products. In general lighting equipment, compared with traditional white light source or fluorescent light source, LED has the advantages of simple structure, low power consumption and durability.
Mr. Lu pointed out that LEDs are not really novel electronic components, but the scale of applications in the past is small. The reason is that LEDs used mainly in standard construction, which failed to flexibly match the design of the final product, and the luminosity is not high; however, Nichia Industrial Co., Ltd. has invented a new technology that uses blue LEDs to excite yellow fluorescent light to create white light, thereby greatly increasing the brightness of LEDs. LED applications have been extended to large display screens or lighting systems.
At the same time as the development of LED technology, researchers have also noticed that the brightness, durability and efficiency of high-power LEDs operating at high temperatures will also be attenuated; therefore, solving the problem of LED heat dissipation is quite important, and ASTRI is Starting with materials and structures.
The technology platform developed by ASTRI can effectively improve the brightness and uniformity of LEDs; it involves the design of components and components, material development, and optical and thermal design, and uses chip-on-board, three-in-one or four-in-one An LED construction technology with more than 20 patents. The LED light source model developed by ASTRI has excellent heat dissipation capability and uses automatic repairing faulty components to tolerate serious defects and faults, making the lighting system more reliable.
At present, ASTRI is developing applications that incorporate these technologies, such as automotive headlights, backlights for LCD TV screens, and general lighting systems. In the earlier "National National Semiconductor Lighting Engineering Innovation Competition 2006", the application of "Active LED backlight module in large-size LCD TV" jointly designed by Yingke and Huagang Optoelectronics and TCL Technology Center was awarded this year's Product Innovation Award.
