Abstract:
An LED lamp driven by alternating current includes at least a first constant-current supplying device, at least a second constant-current supplying device and at least an LED load. A terminal of the first constant-current supplying device is connected to the first connecting terminal of the AC power source. A terminal of the second constant-current supplying device is connected to the second connecting terminal of the AC power source. The LED load is connected between the first constant-current supplying device and the second constant-current supplying device in series. Through the current limiting function of the first constant-current supplying device and the second constant-current supplying device, the LED lamp may be protected.
