Integrated Thermal Management Technology

When is thermTECH required ?

When luminaires are left running during the day or to prevent thermal runaway.

What is required for thermTECH in an application ?

High wattage & external luminaires need an intelligent LED driver with NTC capabilities.

NTC : Negative Temperature Coefficient

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.
