Title:
REFLECTIVE ILLUMINATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/203258
Kind Code:
A1
Abstract:
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.
