This application note provides cautions/suggestions for the thermal design of the chosen application using the NFMW48xAR series LEDs showing the evaluation results to ensure that the required luminous flux for the chosen application is obtained. Thermal design is very important for LEDs since it determines the optical and electrical characteristics (e.g. luminous flux, forward voltage, etc.) of the LEDs and it even affects the lifetime of the LEDs. When performing a thermal evaluation, customers must check how high the junction temperature of the LED will be when the LED is operated in the conditions/environments in which the LED will actually be used.
