led The LED is an abbreviation for Light Emitting Diode. In 1955, Rubin Braunstein of RCA Corporation of the United States discovered the infrared radiation of GaAs and other semiconductor alloys. In 1962, Nick Holonyak Jr of GE in the United States developed visible light LEDs. In the past, LEDs were usually only used for indicator lights and display panels. The real take-off was after the appearance of white LEDs in the 1990s. Nowadays, it has been mainly used as an alternative light source for incandescent lamps and a backlight for LCD TVs to replace the previously used cold cathode fluorescent tubes (CCFLs). LED lighting In 1880, Edison invented the light bulb, revolutionized human lighting, improved the civilized life of mankind, and accelerated the vigorous development of the global economy and lighting industry. Today, low-carbon energy-saving has become an era requirement, and LED lighting fixtures that can replace incandescent bulbs have become the second revolution in human lighting technology and are expected to be high. According to statistics, in 2005, the global electricity consumption of lighting accounted for 19% of the total power generation, costing 365 billion US dollars, accounting for 1.2% of the world's GDP, and emitting a total of 525 million tons of CO2. LEDs are used as lighting for wall lights that began 10 years ago, and then used as street lights, and then for indoor lighting such as ceiling lights, spotlights and fluorescent lights . The LED light source has low power consumption, long life (more than 10 years of use), fast response, moisture resistance, shock resistance, and sturdiness, and is easy to maintain, light and short. In addition, advanced countries have been implementing policies to ban and sell traditional incandescent lamps, so the LED lighting market is undoubtedly good. According to the latest report from the Yano Institute of Economics in Japan, the market for white LEDs for lighting in the world was only 4 billion yen in 2004. In 2008, it grew to 40.2 billion yen (330 million), accounting for the entire white LED market (340 billion yen, 190). Billion) l2%. It is expected that the white LED for lighting will grow rapidly to 413 billion yen in 2013, doubled in five years, and is expected to reach 708 billion yen in 2018. The average annual growth rate during the year of l0 is as high as 33%. Prices have fallen (in lumens, about 30% per year), applications have continued to expand, and the market has been in short supply, causing many companies to participate, and Japan has joined giant companies such as Panasonic, Toshiba, NEC, Rohm and Sharp. Needless to say, LEDs for lighting still face many problems to be solved, such as the linear pointing operation mode of LED as a point source, through efforts to improve its diffusivity. The heat dissipation, color and light properties must be improved, the luminous efficiency is improved, the package is improved, and the problem of arsenic harmful objects in the production process is particularly solved.
