ABSTRACT
The purpose of this paper is to explore the relationship between the driving method and temperature of high brightness white LEDs today. The temperature of high brightness white LEDs varies depending on the driving method, but this variation also affects the life of high brightness white LEDs. However, this variation also affects the life time of high brightness white LEDs. The best driving mode is found in the constant current driving method in LM317.
Keywords: White LED, LM317, constant current driving method.
