摘要： Disclosed are a light irradiation apparatus that prevents or suppresses projection of light on adjoining other portions and can be miniaturized overall, and a photocurable material treatment apparatus that includes this light irradiation apparatus.The light irradiation apparatus according to the present invention includes, with three mutually orthogonal directions as an x direction, a y direction and a z direction: a long light source unit in which a plurality of light emitting elements are disposed in a state of being arranged in the x direction along a plane extending in the x direction and the y direction; and a cylindrical lens that has an elongated shape extending in the x direction along the light source unit, a longitudinal peripheral surface of the cylindrical lens including a light reception surface for receiving light from the light source unit and a light-exiting surface for allowing the received light to exit therethrough. The light source unit is disposed so that a light source reference plane that includes a center of a light emission surface of each light emitting element and extends in the x direction and the z direction is located on a plane separated in the y direction from a lens reference plane that includes a center axis of the cylindrical lens and extends in the x direction and the z direction. A direction of the light from the light-exiting surface of the cylindrical lens is tilted in a direction away from the light source reference plane with respect to the lens reference plane.

摘要： A light source device includes a casing, and a plurality of light source units arranged side by side in the casing. Each of the light source units has a heatsink, a light emitting element substrate attached to the heatsink, light emitting elements mounted on the substrate. The light source device also includes a plurality of cooling fans such that they face cooling fins of the heatsinks. The light source units are arranged side by side in a direction orthogonal to the extending direction of the cooling fins of the heatsinks, the cooling fans are arranged side by side in the same direction as the arrangement direction of the light source units, and a partition plate that extends substantially parallel to the extending direction of the cooling fins and toward the cooling fins is disposed between each two adjacent cooling fans.
