PURPOSE:To provide a sheet for reflectors capable of efficiently making the light of the curved tube part of an L-shaped linear light source or U-shaped linear light source incident on a light transmission plate by curving the sheet and a surface light emitting device formed by using this sheet. CONSTITUTION:This sheet 5 for reflectors is obtd. by cutting a film deposited with silver by evaporation in such a manner that the sheet consists of a base reflection part 11 having a plane L shape, band-shaped side face reflection parts 21, 22 respectively continuously disposed on the outer side of the L-shaped longitudinal side and the outer side of the L-shaped transverse side of the base reflection part 11, a band-shaped front surface reflection part 31 disposed continuously on the outer side of the respective side face reflection parts 21, 22 and a tongue piece 41 disposed continuously from the one end edge of the other side face reflection part in a direction orthogonal with the extension line of the one side face reflection part. Then, the side face reflection parts 21, 22 of the sheet 5 for reflectors of the surface light emitting device on which the L-shaped light linear light source is arranged, are curved and the ends of the light transmission plate are held by the base reflection part 11 and front surface reflection part 32 of the sheet 5 for reflectors. The respective straight tube parts of the L-shaped wire light source is covered with the side face reflection parts 21, 22. The curved tube part of the L-shaped linear light source is covered by bending the tongue piece 41. |
