Abstract
A driving circuit of light emitting diodes includes a power supply circuit, at least one bypass circuit, and a temperature control circuit. The power supply circuit is used for providing a driving voltage to at least one series of light emitting diodes. Each bypass circuit of the at least one bypass circuit is used for being turned on when an ambient temperature is lower than a predetermined temperature. The temperature control circuit is coupled to the at least one bypass circuit for detecting the ambient temperature, and sending a control signal to the at least one bypass circuit when the ambient temperature is lower than the predetermined temperature. Therefore, the driving voltage can still drive the at least one series of light emitting diodes when the ambient temperature is lower than the predetermined temperature.
