ABSTRACT:
The light irradiation device of this invention intends to further facilitate an assembling procedure and to stabilize the quality as a product.The light irradiation device comprises an LED5, an optical unit4that makes an engagement with the LED5with their axial lines aligned with each other, a tubular first housing element2having an opening D at its rear end surface for inserting the optical unit4and the LED5into the inside of the first housing element2, a deciduous inhibition member R that makes an engagement with a vicinity of the opening D of the first housing element2and that prevents the optical unit4that has been inserted into the first housing element2from dropping off, a second housing element3that blocks up the opening D by being mounted on a predetermined position of the first housing element2and that forms a housing CS together with the first housing element2, and a projecting member10that is arranged on the second housing element3to project forward, and at the predetermined position, the projecting member10presses the rear surface of the LED5to engage the optical unit4and the LED5, thereby to align their axial lines.
