Claims

[Claims for Utility Model Registration] (1) In a distributed surface light source consisting of a light emitting diode and a dispersion member that disperses the light emitted from the light emitting diode, the dispersion member is a translucent member having a reflective layer on the back surface. The back surface of this translucent member is formed into a tapered shape that gradually spreads toward the opening on the outer periphery of the front surface, and a reflective layer is provided on this tapered back surface, and a reflective layer is provided in the center of the tapered shape. A distributed surface light source using light emitting diodes, characterized in that the light emitting diodes are installed facing forward through the light emitting diode. (2) A distributed surface light source using a light emitting diode according to claim 1 of the utility model registration claim, wherein the light-transmitting member is a transparent synthetic resin. (3) A distributed surface light source using a light emitting diode according to claim 1 of the registered utility model, wherein the light-transmitting member is an acrylic resin. (4) A distributed surface light source using a light-emitting diode according to claim 1, wherein the light-emitting diode is closely attached to a light-transmitting member via a light-transmitting adhesive. (5) A distributed surface light source using a light emitting diode according to claim 1 of the utility model registration claim, wherein the transparent member is provided with a colored layer having the same color as the emitted light color of the light emitting diode between the light transmitting member and the reflective layer. .
