PURPOSE:To apply the light source device to ornamental and large light source devices and to sharply expand the purposes of the face light source device by fixing a light source to a white group curved face plate end part having an irregular reflection part and facially emitting the face plate. CONSTITUTION:An acrylic transparent plate 8 on a roof panel 6 of a bus shelter 1 forms a curved face 10, a screen printed irregular reflection part 9 and a transparent resin plate 12 are formed on the upper face side and an optical diffusion sheet 13 is laminated on the lower face part. A fluorescent lamp 13 is arranged inside the part formed by the cover part 5 of the end part of the panel 6 and a horizontal frame 2b. When the lamp 13 lights up under said constitution, the whole face of the curved face 10 is emitted, the inside of the bus shelter 1 is brightly illuminated and the whole is brightened together with a side wall face plate 14, so that the panel 6 can be easily recognized from a far place. Said constitution can be applied also to ornamental and large face light source devices and can be allowed to correspond to the variety of designs. |
