LED luminous efficiency, temperature rise and life standard part of the key technical indicators, such as view CREE or Osram LED data released by the industry, its chip PN junction temperature Tj <85 ℃, can only ensure that the working life of up to 5 million hours and the chip PN to bind to its own thermal film (Tjs) temperature rise ΔT = 6 ~ 15 ℃ between the other LED light efficiency and operating temperature is inversely proportional to performance characteristics, each increase in 10 ℃, can lead to bad light and the life of 5 to 8% reduction half of the serious consequences, and general publicity LED can work at 100 ℃ service life of up to 10 thousand hours a far cry from the idea.
