Integrated Thermal Management Technology When is therm TECH required ? When luminaires are left running during the day or to prevent thermal runaway. What is required for therm TECH in an application ? High wattage & external luminaires need an intelligent LED driver with NTC capabilities.
WHAT IS NTC? NTC : N egative T emperature C oefficient The function of the NTC is to send a signal to the LED driver to reduce the output current to the LED’s. This is done when the temperature is too high. It will reduce the current therefore reducing the heat. Current VS Heat (110°) LED max temp Temperature(°C) (110°) Temperature Current(mA)
