A light guide system for receiving and transporting ambient light by means of light guides, which system comprises at least one light collecting unit for receiving light and light transporting means to transport the received light to a location remote from the unit, is described wherein the said light collecting unit comprises a number of light guides, the light receiving ends of which are arranged in a two dimensional array of rows and columns whilst downstream these ends the light guides stepwise compose to a number of outgoing transport light guides, which number is substantially lower than the number of light receiving ends and which transport light guides constitute said light transport means. The system has a large light-collecting capability and can be made very compact and is especially very suitable for a road marking system. |
