PROBLEM TO BE SOLVED: To provide a luminous apparatus that can easily perform a material management with a low cost, can obtain a good efficiency of manufacturing work and can obtain a stable white color light. SOLUTION: It makes light from LED 13 incident from a bottom surface of a light guiding plate and makes it emit from a top surface wider than the bottom surface. The bottom surface side of a light guiding body is provided with a fluorescent material layer 14 precipitated when hardening by mixing the fluorescent material with a resin. |
