PURPOSE: To ensure the production effect of the ceiling of a bath room by simple constitution by mounting a sheet, on which an arbitrary pattern is drawn by luminous paints, on the internal surface of the ceiling and installing a near ultraviolet-light irradiating lamp applying near ultraviolet light towards the sheet onto the bath room. CONSTITUTION: A main switch near an inlet for a bath room 1 is lit and operated and an illuminating lamp is lit up preferentially, and entrance and exit are facilitated even in the dark bath room 1. A user M depresses a changeover switch 31 arranged near a bath tub 2 while taking a bath and a near ultraviolet light switch is turned on, and the illuminating lamp is put out and a sheet 21 is irradiated with near ultraviolet-light irradiating lamps 25. Accordingly, patterns 22 drawn by luminous paints fluoresce and shine, and the user M takes a bath while seeing the patterns 22 on the surface of a ceiling 6 and can relax. |
