PROBLEM TO BE SOLVED: To provide a medical lighting device capable of optionally selecting an irradiation distance while suppressing manufacturing costs.SOLUTION: An irradiation control portion 32 having a passage hole portion 34 through which light of an LED 20 passes, on a position deflected from an optical axis in the direction orthogonal to the optical axis, is disposed between the LED 20 and a convex lens body portion 23, thus an image point (position of irradiated image) is deflected to a side opposite to the deflecting direction of the passage hole portion 34 with respect to the optical axis as a reference. Lights of light source portions are collected at a side separating from the convex lens body portion 23 by the deflection of the image point.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】作製費用を抑え、任意の照射距離を選択することができる医療用照明装置を提供する。【解決手段】LED20の光が通過する通過孔部34を、光軸よりもこの光軸と直交する方向にずらして形成した照射制御部32をLED20と凸レンズ本体部23との間に取り付け、このことによって、光軸を基準として通過孔部34をずらした方向の逆側に像点(照射像の位置)をずらす。像点がずれた分、凸レンズ本体部23から離れた側で各光源部の光が集まる。【選択図】図3
