Abstract

PURPOSE:To utilize the sunlight for a heat energy source and an illuminating beam, by forming a reflecting surface on the outer circumference surface of a flexible transparent pipe to reflect the light to the inside of the pipe. CONSTITUTION:A light transmission tube (a) is obtained by forming a light reflecting surface on the outer circumference surface of a flexible transparent pipe 1 to reflect the light to the inside of the pipe 1. A condenser lens 7 is provided with a proper space secured to an end of the tube (a) protruded on a light gathering plate 5. The tube (a) led into a room 6 is connected to a light diffusing part 8 provided on the ceiling. The sunlight irradiated from the other end of the tube (a) is diffused through the part 8 by means of a diffused reflection plate, etc.
