PURPOSE:To make it possible to take measure for a person to recover from fatigue from a mental point of view rather than the visual sense by applying colored light in a light emitting device to air bubbles generated from an air bubble generating device. CONSTITUTION:An air bubble generator 6 is actuated and a light emission device is actuated at the time of taking bath. A light emitting part 8 attached with a temperature sensor, and investigates the temperature of a bath tub or the temperature of air bubbles. Colors are changed for every temperature to provide bathing information. Further, the color of air bubbles is controlled to a preferred color or a color increasing a metal feeling. Since the light emitting part 8 is a part receiving heat from the bathtub 1 and a heat exchanger 4, a heat emitting member and a base control substrate are put into a control part 10 which is separated from the light emitting part 8 by means of a connection cable 9 using optical fibers and electric wires to prevent the influence of heat. |
