Abstract:
A lighting apparatus in which a light emitter (an illumination light source) can be easily reduced in size is provided. The lighting apparatus includes: a light emitter; and an inverter circuit that converts power supplied from a commercial power supply, into AC power, and outputs the AC power to the light emitter, and the light emitter includes: a capacitor; a rectifier circuit that rectifies the AC power obtained through the capacitor; and an LED that emits light using power rectified by the rectifier circuit.
