LIGHT IRRADIATION DEVICE FOR PHOTOCURABLE RESIN PROVIDED WITH CONTROLLER

To obtain an irradiation device capable of solving the problems of shrinkage after curing of a photocurable resin, surface stickiness caused by oxygen inhibition, a strain after curing, and a crack on an end portion.SOLUTION: A light irradiation device for a photocurable resin is provided with: a main body part provided with a light source for irradiating light to cure a photocurable resin; and a control part for controlling irradiation condition of the light from the light source. In the light irradiation device, the light source is provided with: a long wavelength light having a peak wavelength in a long wavelength region among wavelength regions for curing the photocurable resin; and a short wavelength light having a peak length in a shorter wavelength region than the long wavelength light. The control part controls an irradiation amount of the long wavelength light and an irradiation amount of the short wavelength light according to an irradiation control schedule selected from two or more control schedules stored in advance.SELECTED DRAWING: Figure 1 【課題】 光硬化樹脂の硬化後の収縮、酸素阻害による表面のべたつき、硬化後のひずみ、端部のひび割れを解消することが可能な照射装置を得る。【解決手段】 光硬化樹脂を硬化させる光を照射する光源を備えた本体部と、光源からの光の照射条件を制御する制御部とを備えた光硬化樹脂用光照射装置において、光源は光硬化樹脂を硬化させる波長領域の内で長い波長領域にピーク波長を有する長波長光と長波長光に対して短い波長領域にピーク波長を有する短波長光とを備え、制御部が予め記憶された２種以上の制御工程から選択された照射制御工程に沿って光源による長波長光の照射量と短波長光の照射量とを制御するもの。【選択図】 図１
