Abstract
An electronic device includes a plurality of light-emitting elements, a temperature sensor, and a control element. The control element includes a storage unit, a comparison unit, and a first control unit. The storage unit stores a look-up table including different correspondences between different temperature ranges and different power thresholds. The comparison unit receives the first power consumption of the light-emitting elements, determines the predetermined power threshold in the different correspondences of the look-up table according to the ambient temperature, and compares the first power consumption with the predetermined power threshold to determine the second power consumption. The first power consumption is obtained by measuring the light-emitting elements. The first control unit drives the light-emitting elements according to the second power consumption.
