PROBLEM TO BE SOLVED: To perform uniform light irradiation over the whole irradiation area.SOLUTION: An optical hair restoration device includes a plurality of light emitting diodes 4 that irradiate the scalp with light and a rotary plate 2 that rotates around a shaft nearly orthogonal to the scalp. The plurality of light emitting diodes are installed on the rotary plate and, by irradiating the scalp with light while rotating around the shaft together with the rotary plate, nearly uniform light distribution can be obtained within the irradiation area. Connection of the light emitting diodes with a control device 6 for intermittent irradiation of the light emitting diodes is performed through a slip ring which is composed of conductive parts 10, 10 that are installed on the outer peripheral face of the rotary plate 2 and a pair of contact springs 11, 11 that are in contact with these conductive parts.COPYRIGHT: (C)2014,JPO&INPIT【課題】照射エリア全域について均等な光照射を行う。【解決手段】頭皮に向けて光を照射する発光ダイオード4と、頭皮に対してほぼ直交する軸の回りに回転する回転板2を備える。発光ダイオードは回転板上に複数設けられて、回転板と共に軸の回りに回転しつつ頭皮に向けて光を照射することにより、照射エリア内においてほぼ均等な光分布を得ることができる。発光ダイオードを間欠的な照射を行う制御装置6と発光ダイオードとの接続は、回転板2の外周面に設けた導電部10,10と、これら導電部に接触する一対の接触ばね11,11とからなるスリップリングを介して行っている。【選択図】図1
