反射照明系统
Abstract:
一种反射照明系统，其包含照明模块（10），设有出光部（12），出光部（12）产生第一光束（14）；反射装置（20），设置于第一光束（14）的路径上，反射装置（20）的反射面（22）接收第一光束（14）后，反射出第二光束（24）；光偏转装置（30），设置于第二光束（24）的路径上，光偏转装置（30）接收第二光束（24）后，沿光轴（50）反射出第三光束（32）；其中，照明模块（10）与反射装置（20）分别设置于光轴（50）的水平面（54）的不同侧，第一光束（14）所形成的第一发散角（β1）为35～55度，或设定照明模块（10）与反射装置（20）间距离为15～40mm。实现了合理的空间配置，而得以将反射照明系统小型化。
Abstract(English):

A reflective illumination system, including an illumination module (10), which is provided with a light-emitting portion (12), the light-emitting portion (12) producing a first light beam (14); a reflecting apparatus (20), which is arranged on the path of the first light beam (14), and reflects a second light beam (24) after a reflective surface (22) of the reflecting apparatus (20) receives the first light beam (14); a light deflecting apparatus (30), which is arranged on the path of the second light beam (24), and reflects a third light beam (32) along an optical axis (50) after receiving the second light beam (24). The illumination module (10) and the reflecting apparatus (20) are respectively arranged on different sides of a horizontal plane (54) of the optical axis (50), and a first divergence angle (β1) formed by the first light beam (14) is 35-55 degrees, or the distance between the illumination module (10) and the reflecting apparatus (20) is set to be 15-40mm. A reasonable spatial configuration is achieved, so as to enable the miniaturization of the reflective illumination system.
