PURPOSE:To provide an artificial photo-environment similar to the natural one by setting a light source of good color rendering to a proper direction, and by adjusting a position to be lighted as well as quantity of light of each light source, and by forming an artificial shadow by means of shaking a leaf itself. CONSTITUTION:A lighting equipment 2 is mounted and arranged in such a way that it faces a square void 1 of a building. A pseudo-leaf 4 is provided on a framework 3 spread in eight directions from a rotational axis. The pseudo- leaf 4 is rotated by a motor 5 fixed on the lighting equipment 2. On the bottom thereof, a pond 6 and a lighting equipment 2a arranged at random are formed. For the lighting equipment 2, a metal halide lamp is used. In order to obtain the lighting environment as similar to the natural one as possible, a xenon luminous tube of high color temperature is used on the topmost of the void 1, while incandescent lamps of tungsten, etc. are provided in turn to the lower step, whereby color temperature is varied in the void 1. |
