Led led lighting device using the driving circuit and the driving circuit led

There is provided a driving circuit for driving an LED connected to an AC power source via a phase control dimmer LED load, comprising: switching means including a switching power supply and the switching element current detecting part; LED current detecting means; based on the current switch detection signal and the switch element so that the switching member detecting a current having a current value required for a first control means; a detection signal and the switch element current detecting means based LED to LED current having a desired current value a second control section; and when is set as the phase control dimmer control and the phase control dimmer when high brightness dimming executed by the first control means is set to a low light intensity modulation performed by the second control means switching means switching between control.
