Abstract

Disclosed is a lighting device in a radiation panel type, comprising a substantially rectangular enclosure, a pair of substantially planar optical component parts within the enclosure and having optically smooth faces which are facing each other in distances varying gradually in traveling from one end to an opposite end of the pair of optical component parts, wherein one of the optical component parts is transparent and the other is reflective, and a light source apparatus to enter light between the faces at an end of the optical component parts and the enclosure, whereby the entered light reflects off of the reflective optical component part and radiates out through the transparent optical component part.
