description An LED illuminating device without using a capacitor includes a surge absorber group, a three-phase rectifier bridge module, an LED chip group and a current-limiting chip group. The surge absorber group includes a first surge absorber electrically connected between the first and the second AC power input terminal, and a second surge absorber electrically connected between the second and the third AC power input terminal, and a third surge absorber electrically connected between the third and the first AC power input terminal. The three-phase rectifier bridge module is electrically connected to the first, the second and the third AC power input terminal. The LED chip group is electrically connected to the three-phase rectifier bridge module. The current-limiting chip group is electrically connected to the bridge rectifier group. The LED illuminating device can generate a lighting source through a three-phase power provided by a three-phase power supply.
