Abstract
A light emitting device with low voltage-endurance components includes a light emitting diode string, M first control circuits, a detection unit and a current control circuit. The light emitting diode string includes M first light emitting diodes connected in series. Each first control circuit includes a first switch. One end of the light emitting string is coupled to a node of an input voltage. The first switch is connected to its related first light emitting diode in parallel and can enable a bypass current path. The detection unit detects the potential of the input voltage to produce a current detection signal. The current control circuit is coupled to the M-th one of the M first control circuits and the detection unit and controls the M-th one of the M first control circuits to selectively enable the bypass current path according to the current detection signal.
