PROBLEM TO BE SOLVED: To provide a small-sized lighting system and a maker light which can simply change its spectral characteristic. SOLUTION: A light beam emitted from a light source 58 is converged through a lens 35, and is projected onto a transparent part 32. The light beam is divided by a dichroic membrane 36 formed on the lens 35, and a predetermined color light beam is projected from the light transparent part 32. If a green filter part 36a of the dichroic membrane 36 is set for the transparent part 32, a green light beam is projected from the transparent part 32. A plurality of filter parts 36a, 36b having different spectral characteristics are formed on the lens 35, being aligned with the position of the transparent part 32. Accordingly, if it is desired to project a red light beam from the transparent part 32, the lens 35 is turned so as to align the red filter part 36b with the transparent part 32, the red light beam is projected from the transparent part. The light beam to be projected can be changed by turning the lens 35 without replacing the lens 35 with another one, the color of the light beam can be changed. |
