Abstract

Safety improvements to Light Emitting Diodes (LED) are discussed herein. As the LEDs that are part of a luminaire heat up and cool down, the current supplied will be tuned to improve the safety of the luminaire to manage the levels of light and heat produced. At least one thermally active electrical component is incorporated into the LED load of the luminaire, which is communicated to an LED current control to signal when to adjust current levels providing by a driving circuit. Current is reduced when the temperature of the LED load exceeds a threshold, and or returned to an optimal current when the temperature no longer exceeds the threshold.
