< Topic >Being small-sized and lightweight, conveyance is possible, furthermore the cheap portable die LED optical lighting vessel whose dissipation power is little is offered. SolutionsAs for portable die LED optical lighting vessel 1 of this invention, the multiple strings arranging the multiple LED where, the frame it is provided inside 2 where it can provide insertion opening 4 in the front and the frame, it is provided in the lighting chamber 3 of the size which stores the denture floor D and the lighting interior the mount base is provided in the position where opposes with the mount base 5 of 5 which mounts the denture floor D which is interposed from insertion opening 4 and the lighting interior, joints in series the LED group 12,12 which it lays out,Directing to empty mount base 5, while, being internalized in the illuminant 9 which intensively irradiates LED light, and frame 2 converting electricity from commercial business power source to the rated voltage of LED and from the power supply section detecting the electric current which flows to the LED group 12 of illuminant 9 15 which it supplies to illuminant 9 and power supply section 15, when the electric current which is detected exceeds restriction electric current, cutting off the electric current which flows to LED group 12 in order for fixed restriction electric current to flow, having the current limiting circuit 30 which, it controls it is constituted. < Choice figure >Drawing 1【課題】小型かつ軽量で持ち運びができ、しかも消費電力の少ない安価な携帯型LED光照射器を提供する。【解決手段】本発明の携帯型LED光照射器1は、正面に挿入口4が設けられた筐体2と、筐体内に設けられ、義歯床Dを収容する大きさの照射室3と、照射室内に設けられ、挿入口4から挿入した義歯床Dを載置する載置台5と、照射室内の載置台5と対向する位置に設けられ、直列接続した複数個のLEDを複数列並べて配置したLED群12,12,…から載置台5に向けて集中的にLED光を照射する光源部9と、筐体2に内蔵され、商用電源からの電力をLEDの定格電圧に変換して光源部9に供給する電源部15と、電源部15から光源部9のLED群12に流れる電流を検出し、検出した電流が制限電流を超えたときにLED群12に流れる電流を遮断しつつ一定の制限電流が流れるように制御する電流制限回路30を備えて構成されている。【選択図】図1
