IPC: F21S8/12
Filed: 1993-10-20
Abstract: PURPOSE:To heighten a utilization factor of light with simple constitution while exhibiting an original function by making emitting light from a curved light guide incident directly on light guide lenses, and forming incident light in desired light distribution. CONSTITUTION:Light emitted from a light source 10 is made incident on an optical fiber cable, and is emitted into a curved light introducing passage 60. The light incident in the light guide 60 is bent 90 degrees while causing total reflection in the light guide 60, and the emitting light is made incident on light guide lenses 20a and 20b from a plane of incidence, and the emitting light forms desirted light distribution. At this time, refractive indexes of light of a joining part between the optical fiber cable and the light guide 60 and a joining part between the light guide 60 and the lenses 20a and 20b do not change. Thereby, among the emitting light from the light guide 60, corresponding light is made incident on the lenses 20a and 20b between a lower end part 35a of a shade 35 and an upper end part of a shade 36. Then, a necessary minimum radius of curvature becomes small, and a restriction on meandering layout of a cable 30 is relieved, and the whole external shape becomes compact.
