The surface that is not used is the daylighting surface 7, and the back surface and the surrounding side surface of the light-transmissive phosphorescent plate 2 are the reflecting surfaces of the light taken from the daylighting surface 7.

  Next, an example of the manufacturing method of the light transmissive phosphorescent plate 2 will be described and the structure will be described again.

  As shown in FIG. 2A, a mold 8 having a recess 9 for shaping the outer shape of the luminescent sign 3 is prepared, and a light reflecting sheet or a light reflecting plate 4 is installed on the inner surface of the recess 9 as a representative example. To do. In other words, the light reflecting sheet 4 is brought into close contact with the bottom surface and the peripheral side surface of the recess 9 while being in a box shape.

  Next, as shown in FIG. 2B, a large number of phosphorescent particles 1 and glass particles or plastic particles 6 are placed in the recess 9, that is, on the upper surface of the light reflecting sheet 4.

  Next, as shown in FIG. 2C, a synthetic resin or glass having fluidity is filled in the recess 9 to embed the particles 1 and 6 and is in close contact with the light reflecting sheet or light reflecting plate 4 (mother). After material curing, the mold is removed.

  Thus, the luminous particles 3 in which the phosphorescent particles 1 and the glass particles or the plastic particles 6 are embedded, the light reflecting sheet or the light reflecting plate 4 is bonded to the back surface, and the outer shape as the sign is given, that is, the light reflecting sheet or the light reflecting plate. The luminescent label 3 backed up in 4 is obtained.

  As shown in FIG. 3, after filling the recess 9 with a synthetic resin or glass having fluidity in the above step, the phosphorescent particles 1 and the glass particles or the plastic particles 6 can be pushed and embedded from the surface. .

  As shown in FIG. 4, the light-emitting sign 3 is fitted in a recess 9 'provided on the surface of various display bodies 10, and the light-transmissive phosphorescent plate 2 is placed in the recess 9'. Alternatively, the configuration is backed up by the light reflector 4.
