PROBLEM TO BE SOLVED: To provide a light-emitting diode package structure in respect of a solid illumination device.SOLUTION: A solid lighting device is mainly constituted of a package case, a solid light-emitting source and a multilayer light-emitting structure. A reflector housing, the solid light-emitting source located inside the package case, a transparent plastic material sealing the solid light-emitting source in the package case, and the multilayer light-emitting structure located at the transparent plastic material absorbing light flux of the solid light-emitting source and then emitting a light source with a still longer wavelength are included. Either a fluorescent material or a phosphorescent material is to be at the center of the multilayer light-emitting structure, and is to be positioned between the two layers of the transparent plastic materials. |
