Abstract: The invention introduces converging lenses connecting with optical fibers and a device for receiving sunlight that uses these lenses to converge sunlight from every angle of the sun during the day and the collected light beam at the output is quite parallel. To converge light from every angle of the sun, without using any motion part, small lenses are arranged to build a convex surface. Sunlight collected by these lenses become a parallel light beam and are guided by optical fibers. These optical fibers are arranged tightly to build a bundle of optical fibers in order to make it easier to further transmit and to use at the output of the device.
