きなっかた。However, the luminous brightness of these phosphors or luminous structures depends on the performance and quantity of the luminous material contained therein, so that they cannot be put to practical use. Further, in order to improve the light emission luminance, it is necessary to use a backlight as disclosed in Japanese Patent Application Laid-Open No. 8-313903, and it cannot be used as a mall.

【発明の実施の形態】以下、本発明に係る蛍光体の一実
施形態を添付図面にもとづいて説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the phosphor according to the present invention will be described below with reference to the accompanying drawings.

ン等を用いることができる。As shown in FIG. 1, the phosphor 10 has a rectangular phosphor layer 11. Thus, the fluorescent layer 11 is formed by extruding a resin stock solution mixed with a fluorescent pigment. As a fluorescent pigment, "Pikarico" from Chemtech Co., Ltd.
A commercially available product is used under the trade name, and acrylic is used as the resin. Instead of acryl, polycarbonate, polyester, polyamide, polystyrene, or the like can be used.

させるようになっている。On the front surface of the fluorescent layer 11, the back surface of the transparent layer 12 is laminated. The transparent layer is a molded product formed by uniformly dispersing a fluorescent material in an acrylic resin, and its surface is polished. The transparent layer 12 formed as described above allows light rays incident at a right angle from the outside (from the inside) to the surface to pass through the inside (outside), while allowing other light rays to be totally reflected. Has become.

ている。A groove 13 is formed in the surface of the transparent layer 12. Side walls 13 a on both sides of the groove 13 are opposed to the bottom 13 b of the groove 13. That is, by forming such a groove 13, a pair of edge portions 1 opposed to each other across the opening 13 c of the groove 13 is formed in the transparent layer 12.
2a and 12a are formed. A reflector 14 made of a mirror or a substance having a high reflectance is fixed to a pair of bottoms 13b of the groove 13 so as to face the opening 13c directly in front of the opening 13c.

よって決定される。The phosphor 10 constructed as described above is exposed to light under the daylight in the daytime, the back, the surface of the transparent layer 12, and the light passing through at right angles to the surface. At 11, light energy is stored there. How much light energy is stored is determined by the amount of fluorescent pigment contained.

部に照射されるので、輝度が格段に向上する。At night, when the phosphor 10 is no longer irradiated with light, the light energy stored in the phosphor layer 11 is excited and light is emitted outward. Of these rays, those that do not make a right angle to the surface of the transparent layer 12 are:
The light is totally reflected once or several times on the surface of the transparent layer 12 and is emitted from the pair of side walls 13 a of the groove 13. Thus, since the pair of side walls 13a of the groove 13 is opposed to the reflector 14, the light beam emitted from the pair of side walls 13a of the groove 13 is
The light is reflected by the reflector 14, passes through the opening 13d of the groove 13, and is radiated to the outside. That is, the light collected at the edge portion 12a of the transparent layer 12 is reflected by the reflector 14 and radiated to the outside, so that the luminance is remarkably improved.
