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 facin g each other in distances varying gradually in traveling from one end to an opposit e 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 ent er 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. |
