Figures 1 and 2 show embodiments of the present invention;
The figure is a perspective view of the first embodiment, and FIG. 2 is a perspective view of the second embodiment. Figure 3 is an explanatory diagram of the distribution of light on the target surface due to the direct light, Figure 4 is an explanatory diagram of the reflected light, and Figure 5 is an explanatory diagram of the distribution of light on the target surface due to the reflected light. It is an explanatory diagram. FIG. 6 is an explanatory diagram of the distribution of light on the target surface in which direct light and reflected light are combined. FIGS. 7 and 8 are explanatory diagrams of a conventional reflector. Figure 7 is an explanatory diagram of the same flat reflector, in which Figure 1 is the distribution of light due to reflected light, Figure 2 is the distribution of light due to direct light, and Figure 3 is the distribution of light due to reflected light.
Each figure shows the distribution of the combined light. Figure 8 is an explanatory diagram of the arc-shaped reflector, part 1.
The figure shows the distribution of light due to reflected light, the second figure shows the distribution of light due to direct light, and the third figure shows the distribution of combined light. DESCRIPTION OF SYMBOLS 1...Object surface, 2...Reflecting surface, 3...Light source (source), 4...Reflecting plate, 5...Recessed part, 5C...Center part of recessed part, 5E...Boundary part.
Claims (1)
源に対し、該対象面の反対側に位置する反射板で
あつて、 該反射板は、該発生源に対向する部分に凹部が
形成されてなり、 該凹部は、該対象面中の該発生源の直接照射分
布の疎で弱い箇所を増強すべく、断面においてそ
の中央部に向かつて集束される形状をなし、かつ
その境界部が滑らかに移行すべく形成されている
、 ことを特徴とする反射板。[Scope of Claim for Utility Model Registration] A reflector plate located on the opposite side of the target surface with respect to a source of light, heat, etc. that illuminates the target surface in a predetermined area, and the reflector plate is located on the opposite side of the target surface. A concave portion is formed in the opposing portion, and the concave portion has a shape that is focused toward the center in the cross section in order to enhance the sparse and weak spots of the direct irradiation distribution of the source in the target surface. 1. A reflector plate, characterized in that the boundary portion thereof is formed so as to have a smooth transition.
