Title:
ILLUMINATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/203259
Kind Code:
A1
Abstract:
An illumination system, including at least an illumination module (10), which is provided with a light-emitting portion (12) at one end, 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 a same side 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 5-10mm. A reasonable spatial configuration is achieved, so as to enable the miniaturization of the illumination system.
