Thermal Design Considerations for the Nichia E11A Series LEDs

This application note provides the thermal design considerations for the Nichia E11A Series LEDs, the results of the thermal evaluations Nichia performed, and how to evaluate the junction temperature (TJ) of the LEDs in the chosen application. When an LED is operated, if the heat is not appropriately dissipated it may cause the components and/or materials to deteriorate due to the self-heating of the LED leading to a performance/reliability degradation of the LED (e.g. reduction in the brightness, shorter lifetime, etc.). Proper thermal design is necessary to achieve the performance that is specified in the applicable specification of the LED.
