Natural lighting apparatus.

摘要

A natural lighting apparatus including: a mirror (12) having a mirror face for reflecting light; a supporting mechanism (4, 8) for supporting the mirror (12) to be rotatable about both a first axis and a second axis perpendicular to the first axis; a first sensing mechamsim (44) for sensing a first direction of the light source about the first axis for generating a first signal representative of the first light source direction about the first axis; a second sensing mechanism (46) for sensing a second direction of the light source about the second axis for generating a second signal representative of the second light source direction about the second axis; an attitude control mechanism (30, 34) for angularly moving the mirror about the first axis according to the first signal from the first sensing mechanism (44) and about the second axis according to the second signal from the second sensing mechanism, thus controlling the attitude of the mirror to reflect light from the light source in a predetermined direction.
