Abstract:
An LED drive circuit in which a bright change of an LED is suppressed even if the voltage of a full-wave rectified waveform fluctuates is provided. The LED drive circuit includes a bridge rectifier circuit, an LED string made up by a plurality of LEDs being connected in series and supplied with a current from the bridge rectifier circuit, and a current limiting circuit that has a current input terminal and a current output terminal connected onto a path that starts from the bridge rectifier circuit and returns to the bridge rectifier circuit via the LED string, which limits a current that flows through the LED string to an upper limit current value or smaller, and further, which decreases the upper limit current value in accordance with the amount of rise in the voltage when the voltage at the current input terminal viewed from the current output terminal rises.

Claim (Index 10):
The LED drive circuit according to  claim 8 , wherein\n the current limiting circuit further comprises a series circuit of a fourth zener diode whose anode is connected to the other end of the sixth resistor and a resistor connected to one end of the fifth resistor or one end of the sixth resistor.
