Solve for the maximum junction temperature (T J,MAX) by substituting the values in bold above into Equation 2, yielding Equation 4: Equation 4: Maximum Junction Temperature. This junction temperature ...

Reading junction temperature directly is not possible, because there is thermal impedance from the junction to the slug and from the slug to the board as shown in Fig 3. 3. LED thermal resistance ...

The researchers’ new method entails mounting the LED on a temperature-controlled heat sink set to the desired LED junction temperature between 10 and 100 °C.

At least 70% of the energy put into an LED during operation is converted to heat rather than visible light so, in order to keep the LED junction temperature within its safe operating temperature, this ...

Two new LED controllers—the LDS9001 and LDS9003—feature a patent pending LED-Sense temperature-compensation engine. This innovative feature allows for direct in-situ monitoring ...

Junction Temperature Tester by Acorn Technology is an EIA/JESD51-1 compliant instrument that measures LED junction temperature directly. This instrument uses dynamic mode cyclic testing method ...
