PURPOSE:To utilize infinite light energy and to use hardware according to the purpose of use by converging the sunshine through a lens, etc., and projecting the light out through a pipe made of quartz, plastic, etc. CONSTITUTION:The sunshine 1 which is converged on the focus of a lens, etc., is dispersed widely, so the focus 2 is set in the entrance of a pipe 3, whose internal wall is curved longitudinally and slanted, so that the light is projected out after passing through the pipe where its light refraction is small and then where it does not slant and is equal in internal diameter. Namely, the internal diameter of the pipe 3 before the projection is equalized so that the projection light is not dispersed. Further, the pipe 3 used a logically matched pipe formed by covering a glass pipe which has a large refractive index with glass which has a low refractive index so that the light is reflected totally.
