[origin: EP1486722A2] The arrangement has at least one light conducting channel (1) for transporting light, especially daylight and/or sunlight, with walls closed to at least one light inlet opening (2) and at least one light output opening. A light deflection system (5) is arranged near the light inlet opening for deflecting the light entering the channel into a narrower or wider angular region (beta) about the longitudinal axis (23) of the channel.
