Abstract:
A highly focusing observation light, comprising a ring-shaped light cover (2) being hollow in the middle and a matching ring-shaped light tube (3). During illumination, the invention assists a user to observe an object being illuminated from the central hollow region, effectively increasing a lighting effect. The observation light further comprises a cover plate (4). The invention uses an electrically-controlled rotation shaft (5) to drive the cover (4) to realize opening and closing of the cover (4) with respect to the central hollow region of the ring-shaped light cover (2). A reflective layer is disposed at the bottom surface of the cover plate (4). When the cover plate (4) closes the central hollow region of the ring-shaped light cover (2), the invention can be used as a conventional light, and thus the invention can realize both a conventional lighting effect and a highly focused light effect.
