LED灯及具备其的照明装置
摘要：
本发明提供一种能够不变更卤素灯所使用的光学系统而使用LED灯来代替该卤素灯的用于舞台照明等用途的LED灯。LED灯(50)由多个LED(52)及支柱(54)构成，支柱(54)由多边形的截面形状规定，并具有配置LED(52)的侧面。并且，将支柱半径(S)相对于碗状的反射器(12)的开口(22)的半径的尺寸比率即支柱径比率(D)设为3.73％以上且18.25％以下，其中，反射器(12)在内侧具有使来自LED灯(50)的光反射的反射面(20)，并具有放射由反射面(20)反射的光的开口(22)，支柱半径(S)为从支柱(54)的中心点(C)到侧面的距离。
摘要（英）：

The present invention provides a LED lamp capable of using a LED lamp to replace a halogen lamp for stage illumination without change of the optical system used by the halogen lamp. The LED lamp (50)includes a plurality of LEDs (52) and a pillar (54) that is defined by a polygonal cross-sectional shape and includes a plurality of lateral surfaces on which the plurality of LEDs (52) are disposed.Additionally, a pillar radius ratio (D) is set to fall in a range of greater than or equal to 3.73% and less than or equal to 18.25%. The pillar radius ratio (D) is defined as a dimensional ratio of apillar radius (S) to a radius of an opening (22) of a reflector (12) made in shape of a bowl. The pillar radius (S) is defined as a distance from a center point (C) of the pillar (54) to each of theplurality of lateral surfaces. The reflector (12) includes a reflective surface (20) on an inner side thereof so as to reflect rays of light emitted from the LED lamp (50), and causes the rays of light reflected by the reflective surface (20) to be irradiated from the opening (22).
