automatically provide maximum light output in various fixtures and operating conditions while
assuring long-term lumen maintenance. LEDSense
®
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 (extrapolated per IES TM-21-11). 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.
