CONSTITUTION:The projecting lens parts 15... consisting of the section of the arc larger than the curvature of the unit lenses 13... are formed in accordance with the units lens 13... on the exit light surface 11A of the body 11. The collimated beams of light entering from the front surface 11B on the body 11 are converged by the projecting lens parts 13... and progress so as to focus at a specified position. Since the projecting lens parts 15... are disposed on the exit surface 11A at the intermediate point of the optical path, the rays refract further so as to focus at the position in proximity to the exit surfaces 11A. As a result, the angle of the diffusion of the rays increases and are projected over a wide range. The observable range is widened in this way and the brightness in the peripheral part of the plane image is increased.
