STAINPROOF LIGHTING BODY

摘要

PROBLEM TO BE SOLVED: To provide a stainproof lighting body by a light-emitting system of energy-saving and space-saving which is superior in photo-excitation of photocatalyst and suitable for indoor use.

SOLUTION: The stainproof lighting body has an LED light source immediately below a light-transmitting material, and a photocatalyst layer 6 is laminated directly on the light transmitting material 1. The LED light source comprises an LED (1) 3 emitting wavelength of peak wavelength 350-390 nm and the LED (3) emitting visible light and/or the LED (3) 4 emitting white light. The light-emitting time of the LED (1) is controlled so as to emit light for 1/100-99/100 per unit light-emitting time of the LED (2) and/or the LED (3).
