LEDSense ® Operation, Thermal De-rating and Lumen
The Linear engine employs TERRALUX’s patented LEDSense ® Thermal Management Technology to
automatically provide maximum light output in various fixtures and operating conditions while
assuring long-term lumen maintenance. LED-Sense
® regularly measures the operating temperature
and ensures compliance with a pre-programmed temperature and drive-current profile. This profile
is based on the LED manufacturer’s LM-80 data report and minimum L70/60,000 hour lumen
maintenance curves. LEDSense
® is always active, and will compensate for variation in thermal
conditions due to heatsinking, ambient air, Engine positioning, or any other variable that affects the
operating temperature. The Thermal De-rating curve below identifies the relative light output that
can be expected under various thermal conditions. The LEDSense
® Power Curve identifies the
reduction in input power over temperature.
