Title:
LIGHTING FIXTURE WITH DISPLAY BOARD
Document Type and Number:
Japanese Patent JP3280524
Kind Code:
B2
Abstract:
PURPOSE: To closely stick a display board to the surface of a light guide board so as to improve surface luminance (average luminance) of a display face.
CONSTITUTION: A light source 7 is arranged in at least one side face of a transparent light guide board 5, light radiated from the light source 7 is focused on the light guide board 5, and the light is emitted from the inside of the light guide 5 to the front/rear faces of the light guide board 5 so as to display. In this state, a display board 2 which is added to the surface of the light guide board 5 and a diffusion reflection board 8 which is added to the rear face are so formed as being bent to the light guide board 5 in projecting states. The display board 2 and the diffusion reflection board 8 are attached to the light guide board 5 in such a state as sandwiching the light guide board 5 between the display board 2 and the diffusion reflection board 8.
