Junction temperature is the temperature internal to the LED chip. Junction temperature is a critical measure for evaluating an LED lighting product’s ability to deliver long life. The U.S. Department of Energy advises:
“Heat management and an awareness of the operating environment are critical considerations to the design and application of LED luminaires for general illumination. Successful products will use superior heat sink designs to dissipate heat, and minimize junction temperature. Keeping the junction temperature as low as possible, and within manufacturer specifications, is necessary to maximize the performance potential of LEDs.”
That DOE’s statement above can be said to be the Mission Statement for ALLED and is strictly incorporated into the design and engineering of its product.
