Abstract
A hexagonal-shaped chamber for taking a light bath has inner reflecting mirror surfaces and a plurality of light guides for radiating visible light rays into the chamber. One of the six side walls of the chamber is constructed as a door to be opened and closed. Some of the light guides are connected at their light-emitting ends to the other walls of the chamber at different levels so as to emit the light rays toward the inner opposite reflecting surfaces of the chamber. The remaining light guides are connected at their light-emitting ends to the top surface of the chamber so as to emit the light rays from their ends towards the inner bottom surface of the chamber.
