Huang Guoxin, chairman of Liansheng Optoelectronics, said today that LED will be the industrial revolution of the 21st century. After entering the field of lighting, Edison will invent the light bulb.
Huang Guoxin is known as the godfather of high-power LED in Taiwan. The formerly established Guolian Optoelectronics was merged into Jingdian, and currently it is the chairman of Liansheng Optoelectronics. Huang Guoxin attended the "LED forum2009" to talk about the LED industry. In addition to introducing the origin and history of LED, he also mentioned the LED development he had foreseen 15 years ago.
Huang Guoxin pointed out in 1994 that "the industrial revolution of the 21st century" pointed out that "if the industrial revolution of the 20th century is a computer information industry based on silicon semiconductor materials, the next wave will be LEDs based on compound semiconductors. Industry. At that time, the light bulb invented by Edison will be retired and buried in the history record."
For LEDs to enter the field of lighting, Huang Guoxin proposed several important indicators, the first is the luminous efficiency of the applied lamps, must be higher than 80 lumens per watt; the second is reliability, the light decay rate does not exceed 3-5% every 2 years; third It is the life expectancy of at least 30,000 to 50,000 hours; the fourth is the failure rate, which must be less than 10 PPM; the fifth is the price recovery. The time difference of the electricity saving method can be less than one year, in order to reach a large number of application thresholds. There are other such as color rendering, color temperature and so on.
