LED junction surface temperature and the luminous efficiency of the diagram, when the junction surface temperature increased from 25 ℃ to 100 ℃, its luminous efficiency will decline 20% to 75%, ranging Among them, 75% of the yellow light most serious recession. In addition, when the temperature higher LED operating environment, its production life is lower when the operating temperature from 63 ℃ to rise to 74 ℃, when, LED average life expectancy will be reduced 3 / 4. Therefore, to enhance the LED luminous efficiency, LED system, thermal management and design of bulk has become an important issue then, in understanding the LED heat problem, you must first understand the way of its heat, thus cooling the bottleneck for the improvement.
