Subject: Automotive LED Lighting-High temperature on the LED also has a great impact on life expectancy
2010-03-01


High temperature on the LED also has a great impact on life expectancy. The impact of temperature on the brightness is linear, but the impact of life is exponential, and use the same junction temperature shall prevail, if the use remained below 50 ℃, then the LED nearly 20,000 hours of life, 75 ℃ were only the service life of 10,000 hours, 100 ℃ left 5,000 hours, 125 ℃ left 2,000 hours, 150 ℃ left 1,000 hours. The temperature from 50 ℃ to become twice the light of 100 ℃, service life of 20,000 hours reduced from 1 / 4 times 5,000 hours, so heat will be most profound impact on the life of LED.
