Title:
LIGHT IRRADIATION DEVICE
Document Type and Number:
Japanese Patent JP2018086611
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light irradiation device capable of emitting ultraviolet light, to a cubic irradiation object moving in one direction, not only from the lateral side in a carrying direction but also from the front side and the rear side.SOLUTION: Provided is a light irradiation device where ultraviolet light is emitted to a cubic irradiation object moving along a first direction to cure an ultraviolet curable resin applied to the surface of the irradiation object, comprising: a light source apparatus having a plurality of LED elements arranged along the first direction on a substrate and applying ultraviolet light from a second direction orthogonal to the first direction; and a reflection mirror arranged at an opposite position relative to the light source apparatus with the irradiation object interposed therebetween and reflecting a part of the ultraviolet light applied from the light source apparatus to the irradiation object, and the reflection mirror has a plurality of reflection planes tilted at a prescribed angle to the first direction when being viewed from a third direction orthogonal to the first direction and the second direction.SELECTED DRAWING: Figure 1
