Abstract

PURPOSE:To simplify projectors and improve their reliability by reducing number of lamps as light sources and amount of wire remarkably through the application of a light transmission system provided with optical fibers and photo switches. CONSTITUTION:A lamp 31 has a great luminous output as a common light source and the photo output is condensed into an opening surface T1 of a optical fiber cable 41 by a lens 52 through a light amount regulating window 33. A driving circuit 44 is operated by selective signals S. When a photo switch 43 is turned on, the luminous output is divided equally at a distributor 42 through the optical cable 41 and instance, sent to a optical fiber cable 41a connected with a projector 10 corresponding to a right head lamp and to a optical fiber 41b connected with a left head lamp. When an equipment with such a basic structure is applied to a car 200, each projector 220-380 is connected with a projector controlling circuit 210 through optical fiber cable f1-f23 and lighting is controlled suitably.
