Thermal Design Considerations for the Nichia NVSW719AC LEDs

Download Whitepaper
When an LED is exposed to high temperatures for a long period of time, the components and/or materials used in the LED will deteriorate, leading to degradation of the performance, reliability, and lifetime of the LED. Therefore, proper thermal design is important to achieve the performance that is specified in the applicable specification of the LED. Since the Nichia NVSW719AC LEDs require a large input power, the thermal design may be challenging. However, if the increase of the LED temperature can be minimized by appropriate heat dissipation, it is possible to design more compact luminaires with a higher luminance than conventional LEDs. This application note provides the thermal evaluation method for the NVSW719AC LEDs.
