Abstract:
A combined lens includes a first luminescence surface, a second luminescence surface, a first concave surface for reducing surface reflection of light from the light source and for conducting the light to the first luminescence surface, and a second concave surface 26 for reducing surface reflection of the light from the light source and for conducting the light to the second luminescence surface. This allows the same status display to be provided in a plurality of directions by one light source.
