The purpose of this article is to discuss the relationship between current high-brightness white LED driving methods and temperature. Due to the different driving methods of high-brightness white LEDs, their temperature will also change differently. However, this temperature change also affects the life of high-brightness white LEDs. This study will discuss the best driving mode of white LED circuit in two ways of LM317 constant voltage and WS2801 pulse driving modes. It is found from experiments that the pulse driving mode has better characteristics in temperature control than the constant voltage mode.
