ARTIFICIAL SUNLIGHT RADIATING APPARATUS

WIPO Patent Application WO/2011/151974

A1

Provided is an artificial sunlight radiating apparatus which can provide an extended range of radiation without optical redesign. The artificial sunlight radiating apparatus is configured to include a plurality of artificial sunlight radiating units (1A, 1B) which each accommodate an artificial sunlight radiating box (6) for emitting light through an upper face (6B) and a lower face (6A). The unit (1A, 1B) has a reflector (8) located opposite to the lower face (6A) of the artificial sunlight radiating box (6) to irradiate a radiated face (10A) located opposite to the upper face (6B) of the artificial sunlight radiating box (6) with reflected light and direct light, the reflected light having been reflected on the reflector (8), the direct light having been emitted through the upper face (6B) of the artificial sunlight radiating box (6). The artificial sunlight radiating units (1A, 1B) are arranged side by side. Between the artificial sunlight radiating units (1A, 1B), there is disposed a light shield plate (130) which shields leakage of light through the side of each of the artificial sunlight radiating units (1A, 1B), with a gap (δ) formed between an upper end (131) of the light shield plate (130) and the radiated face (10A). A portion of the radiated face (10A) that is located at the boundary between the artificial sunlight radiating units (1A, 1B) is irradiated through the gap (δ) with beams of light from each of the artificial sunlight radiating units (1A, 1B), the beams overlapping each other.
