| Chip PN junction temperature Tj <85 ℃, can only ensure that the working life of up to 5 million hours and the PN junction to the chip itself, thermal films (Tjs) temperature rise ΔT = 6 ~ 15 ℃ between the other LED light efficiency and operating temperature inversely proportional to the performance characteristics, each increase in 10 ℃, can lead to bad light 5 to 8 percent, and half life 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. |
