ることを特徴とする照明装置。In an illumination device for illuminating a light-transmitting display member, a light guide plate made of a light guide material is arranged on the back side of the display member, a light source is placed opposite to a light receiving part provided on an end surface of the light guide plate, and the light guide plate is A reflective surface that reflects light within the light guide plate toward the display member is formed on a surface opposite to the surface facing the display member, and the reflective surface is provided near the periphery of the surface of the light guide plate on which the reflective surface is provided. forming at least one pair of protrusions facing each other or surrounding the reflective surface, and forming a plurality of protrusions on the outer periphery of a reflecting plate having reflective properties or on the inner surface of the protrusions;
The reflecting plate is fitted between opposing convex parts of the light guide plate, so that the protrusions are embedded in the inner surface of the convex part or the outer periphery of the reflector, thereby fixing the reflector to the outside of the reflective surface of the light guide. lighting equipment.
