Abstract

The invention provides a light irradiation device that can reliably prevent ultraviolet rays from leaking to the outside of the light irradiation device and can also prevent heat generation of the housing. The light irradiation device of the present invention is a light irradiation device that irradiates light with respect to an irradiation target conveyed along a first direction, and includes a light source unit having a plurality of LED elements that are aligned with the first direction. The second direction of the intersection irradiates light to the illuminated object; and a shading unit,which is arranged opposite to the light source unit across the conveying path of the illuminated object, and shields light so that the light irradiated from the light source unit does not leak to theoutside, the shading unit It has: a light absorption member that absorbs light irradiated from the light source unit; a frame body that houses and supports at least a part of the light absorption member; and a wind tunnel that is formed between the frame body and the light absorption member and makes cooling wind flow through.
