Abstract
The invention provides a light irradiation apparatus that can adjust widening/narrowing of a light irradiation area and can guide almost whole of light emitted from an LED to the light irradiation area. The apparatus has an LEDand an optical unitfor making light for the LEDpass through itself and emit from its apical surface, and is equipped further with a supporting bodyA for holding the LED on the apical surface and a position adjustment mechanism for adjusting a relative position of the optical unitto the LEDalong an optical axis C direction. The apparatus is configured so that the potion adjustment mechanism make the optical unitmove relative to the LEDbetween a proximity position Pat which a part or the whole of the supporting bodyA is housed in a base end recessand a clearance position Pat which substantially whole of the supporting bodyA comes out of the base end recessso that the apical surface of the supporting bodyA and a base end faceof the optical unitbecome substantially the same height.
