The development of LED car lights LED Safety Light source directly associated with the development. Semiconductor electroluminescence phenomenon as early as 1907 that, due to weak light, mass production difficult and slow. In 1968 Monsanto introduced the light intensity over 20mcd GaAsp / GaAs structure, the red LED.
This is a breakthrough point, greatly accelerated the development of LED. Then have developed a light intensity of 1000mcd red, yellow, green LED, the instrumentation, telecommunications signals received preliminary instructions on the application, the early formation of the LED application market. But because of its light intensity, light attenuation performance issues that can not be widely applied in automotive lighting. Until 1990 the United States, HP, Toshiba has introduced more than 1000mcd intensity of InGaAlP / GaAs structure, red, yellow high-brightness LED and the 1993 invention of InGaN/Al2O3 Japan Nichia blue and green high brightness LED as a symbol, from the technical and the mass production of automotive LED light source paved the way for.
LED lights for the first time in 1985 in passenger cars, the 1986 Nissan300zx automobile brake lights use LED automotive lamps LED marks the official start time. Well-known international brands such as BMW, Cadillac, Buick, Volkswagen, Ford, Mercedes, Toyota, Mitsubishi, Mazda and Skoda has introduced LED car lamps, etc..
LED car light double-digit annual growth rate in 2005, output value reached 546 million U.S. dollars, accounting for 14% of the world's LED applications. China in 2000 in Shanghai Volkswagen Santana 2000 on the first use of LED brake lights. China LED car lamps to 70% -80% annual rate of growth, the output value of more than billion in 2006.
