Abstract
An illumination apparatus is configured simply in a reduced scale while a light emitting diode is used as a light emitting source for illumination. The illumination apparatus includes an LED driving block including an LED bridge circuit formed from a bridge connection of a plurality of diode series circuits each of which is formed from a series connection of a plurality of light emitting diodes and a rectifying diode. A load resistor is connected to a rectification output of the LED bridge circuit. When an AC voltage is input to the LED driving block, the LED bridge circuit rectifies the AC voltage, and the resulting rectification current is used as driving current to drive the light emitting diodes to emit light.
