    • The improved illuminating apparatus comprises a spheroidal mirror, a light source, a spherical mirror and a condenser lens. The spheroidal mirror has such a shape that it is deficient of a portion that would otherwise reflect light that illuminates any portions other than the object to be illuminated, and that the light from the light source which is directed toward said missing portion is reflected by the spherical mirror positioned on the rear side of said missing portion as seen from the light source and makes another reflection by that part of the spheroidal mirror which faces away said missing portion, thereby illuminating the object. The light source is positioned at the first focal point of the spheroidal mirror in such a way that it faces the mirror, and the spherical mirror is positioned in such a way that its reflecting face lies at the second focal point of the spheroidal mirror. An open window for the exit of light beams is provided in the spherical mirror at a position near the second focal point of the spheroidal mirror, and the condenser lens is provided further ahead of the open window (closer to the object to be illuminated).
    • 改进的照明装置包括球形反射镜,光源,球面镜和聚光透镜。 球形反射镜具有这样的形状,即,否则将反射照射除被照射物体以外的任何部分的光的部分的缺陷,并且来自朝向所述缺失部分的光源的光被反射 球面镜定位在从光源看去的所述缺失部分的后侧,并且通过面向所述缺失部分的球形反射镜的那部分进一步反射,从而照亮物体。 光源位于球状反射镜的第一焦点处,使其面向镜子,并且球面镜以这样的方式定位,使得其反射面位于球镜的第二焦点处。 在球镜的靠近球球镜的第二焦点的位置处设置有用于出射光束的开放窗口,并且聚光透镜设置在开窗(更靠近被照射物体)的前方。
