The temperature of the environment significantly affects the electrical and luminous parameters of LEDs in LED light sources, such as forward and reverse current, forward voltage, and LED luminous flux. The effect of environment temperature on the parameters of LEDs with control devices (drivers) based on both current and voltage stabilisers under conditions of high eenvironment temperature is investigated in this pape. The influence of the environment temperature on the electrical and luminous parameters of LEDs when they are powered from the constant voltage source is analysed. The characteristics of LEDs were investigatedin order to determine the most optimal mode of their operation in LED lighting devices. The most optimal mode of operation of LEDs in which their luminous flux and luminous efficacy are the least dependent on the environment temperature was determined.
