Statistics show that reliability decreases by 10% for every 2℃ increase in component temperature. The heat dissipation problem is more serious when multiple leds are densely packed to form a white light lighting system. Solving heat management problems has become a prerequisite for high brightness LED applications. For the relation between chip size and heat dissipation, the most direct way to improve the brightness of power LED is to increase the input power, and the size of p-N junction must be increased accordingly to prevent the saturation of active layer. With the increase of input power, the junction temperature will rise and the quantum efficiency will decrease. \n\n0.32 inch <a href=\"http://www.xlitx.com/datasheet/CL3231AB.pdf\" style=\"color: #333;\">CL3231AB</a> LED Common-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/cl3231ab.html\" style=\"color: #333;\">CL3231AB</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/CL3231BB.pdf\" style=\"color: #333;\">CL3231BB</a> Display <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/cl3231bb.html\" style=\"color: #333;\">CL3231BB</a> Common-Anode CA\n0.32 inch <a href=\"http://www.xlitx.com/datasheet/3312AB.pdf\" style=\"color: #333;\">3312AB</a> LED Common-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3312ab.html\" style=\"color: #333;\">3312AB</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3312BB.pdf\" style=\"color: #333;\">3312BB</a> Display <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3312bb.html\" style=\"color: #333;\">3312BB</a> Common-Anode CA\n\n<hr style=\"border:1px solid;\">\n\n<a href=\"https://gingkoapp.com/led-load-voltage-must-be-lower.html\" style=\"color: #333;\">LED load voltage must be lower</a>\n<a href=\"https://gingkoapp.com/led-brightness-low-key-with-reduced-voltage.html\" style=\"color: #333;\">LED brightness low-key with reduced voltage</a>\n<a href=\"https://gingkoapp.com/different-leds-with-current-and-output-curves.html\" style=\"color: #333;\">Different LEDs with current and output curves</a>\n<a href=\"https://gingkoapp.com/the-working-ratio-change-led-brightness.html\" style=\"color: #333;\">The working ratio change LED brightness</a>\n<a href=\"https://gingkoapp.com/led-heat-dissipation-technology.html\" style=\"color: #333;\">LED heat dissipation technology</a>\n<a href=\"https://gingkoapp.com/led-lamp-work-is-stable.html\" style=\"color: #333;\">LED lamp work is stable</a>\n<a href=\"https://gingkoapp.com/heat-management-with-high-brightness-led.html\" style=\"color: #333;\">Heat management with high brightness LED</a>\n<a href=\"https://gingkoapp.com/heat-dissipation-for-highlight-led.html\" style=\"color: #333;\">Heat dissipation for highlight LED</a>\n<a href=\"https://gingkoapp.com/led-device-to-extract-heat-from-p-n-junction.html\" style=\"color: #333;\">LED device to extract heat from P-N junction</a>\n<a href=\"https://gingkoapp.com/led-lamp-surface-radiation-heat-treatment.html\" style=\"color: #333;\">LED Lamp surface radiation heat treatment</a>"}],"tree":{"_id":"26651e4fe5e53fc49a00001a","name":"Heat dissipation for highlight LED","publicUrl":"heat-dissipation-for-highlight-led"}}
