Document Type and Number:
WIPO Patent Application WO/2005/019723
Kind Code:
A1
Abstract:
The present invention relates to a directional reflective lighting device with planar reflectors, in which a plurality of planar reflectors (1) in parallel with each other are arranged on a frame (4). The frame (4) is rotatably supported on the bracket of the azimuth adjustment mechanism (2) by a transverse main shaft (31). The mechanism adjusting vertical angels (3) is controlled to actuate the frame (4) for driving the planar reflectors (1) thereon. The device adjusts uniformly vertical angles of the plurality of planar reflectors (1) with the simple frame structure, which cooperates with the azimuth adjustment mechanism (2) to make the reflected sunlight always oriented and projected into the region in the predetermined direction.
