Vishay — NTC Thermistors Provide Intelligent Thermal Management Options for High Brightness LED (HB-LED) Lighting Systems

FTMMarch2018-AS-VishayNTC-tile-200x200

High brightness, high power LEDs (HB-LEDs), although quite efficient light sources, still generate a lot of heat. When not controlled, high LED-die temperatures can significantly reduce the luminous flux output and lifetime of the LEDs. To ensure a highly reliable LED lighting system, the LED-die temperature needs to be controlled. One of the most efficient […]
