There is disclosed a solar beam collector for use in collecting and condensing solar beams to introduce them into light guides or conductors. To ensure that almost all components of the white light and other radiations including ultra-violet and infra-red rays are introduced into the light guides, parabolic mirrors are employed in order to converge all of the solar beams having various wave lengths at the inlet of the light guides, thereby avoiding the problem of chromatic aberration. The solar beam collector is compact in size and comprises a first parabolic mirror for converging the arriving solar beams, a second parabolic mirror for condensing the beams from the first mirror into parallel beams, a third parabolic mirror for converging the parallel beams from the second mirror at a fixed focus, and a light guide having an inlet end placed at the focus of the third mirror.
