Abstract

PURPOSE: To generate a uniform and soft scattered light across a wide area range by combining a face-shaped transparent body whose at least one face is a rough face, cover covering the end face, and light source made incident through the end face of the face-shaped transparent body to a light beam transparent body. CONSTITUTION: A face-shaped transparent body 1 with thickness whose at least one face has a rough face 2, cover 5 covering an end face 1a of the face- shaped transparent body 1, and point or linear light source set in the cover 5 made incident through the end face 1a of the face-shaped transparent body 1 to the light beam transparent body 1 are combined. The rough face 2 is added to one or both faces of the board face so that a light outgoing from the board surface can be scattered on the rough face 2, the scattering of the light can occur across the whole face, and the board surface of the transparent body 1 can be a face light emitting body. Thus, the soft light scattered in a wider area within the range of brightness by the point or linear light source can be uniformly emitted. Also, this device can be made thin, and also used as an illuminating device for each kind of marking, display, advertisement, guidance, and induction.
