Abstract

PURPOSE: To make surface light emission uniform and improve efficiency by arranging a mesh plate formed of a translucent body between a light emission body and a case opening part. CONSTITUTION: Light emission bodies 4a and 4b are provided in a case 1 and the mesh plate 3 formed of the translucent body is arranged between the light emission bodies 4a and 4b and case opening part A. Therefore, the light emitted by the light emission bodies 4a and 4b is transmitted through the through hole 31 of the mesh plate 3 and part of it is scattered by the translucent body 30 of the mesh plate 3. Further, part of the light is reflected and scattered by the internal wall 2 of the through hole 31 of the mesh plate 3 and at the case opening part A, the transmitted light and scattered light are mixed. Consequently, uniform surface light emission is performed and the direct light which is not transmitted through the translucent body of the mesh plate is mixed at this time, so that the efficiency of the surface light emission is improved.
