ABSTRACT:
A lighting device comprises a light source, a light reflective cylinder, and a light receiving surface receiving light directly from the light source and another light reflected from the light reflective cylinder. The light reflective cylinder has a shape such that light intensity on the light receiving surface is constant. The light source is a linear source of light. The light receiving surface has a width W and includes a flat surface extending in parallel to the optical axis of the linear source of light. The light reflective cylinder extends continuously from opposite ends of the flat surface and is composed of plates each extending in parallel to the optical axis of the linear source of light and having a very small width.
