Abstract

See full text

A light irradiation unit includes a substrate having a longitudinal direction, the longitudinal direction being a first axis direction; multiple light sources arranged along the first axis direction on a first surface of the substrate; a heat dissipation member arranged on a second surface of the substrate opposite to the first surface; and a housing having a pair of first side surfaces holding the heat dissipation member therebetween in a second axis direction orthogonal to the first axis direction along the first surface. The substrate has, at an end portion in the first axis direction, an end surface intersecting the first axis direction. The location of the end surface in the first axis direction is near an edge of the first side surface along the first axis direction. The end surface is exposed from the housing or covered by a detachable protection member.
