<P>PROBLEM TO BE SOLVED: To emit light guided from an incident end surface from a large flat portion, adjoining boundary portions being inconspicuous as lines even when being multiply arranged. <P>SOLUTION: This surface light system 1 comprises a plurality of light sources 9, a first light guiding body 3, a second light guiding body 4, a light source 9 and a reflector 10. The first body 3 consists of an entrance surface part for guiding light from the light source 9, an emitting surface part having larger width than the entrance surface part, two inclined side faces for connecting the entrance surface part and the emitting surface part and two side faces for connecting the entrance surface part and the emitting surface part. The second body 2 has a flat surface part 5 with both ends inclined to the direction of a back surface part 6, side face part made parallel to the surface part 5 and the back surface part 6, both of both the side faces entrance end face parts for guiding light, and entrance end face part having approximately half width than the emitting surface part of the first body 3. Light from the light source 9 is guided from the entrance surface part of the first body 3 and light emitted from the emitting surface part is guided from the entrance end face part of the second body 2, and both the light is emitted from the surface part 5. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
