Description

  The present invention relates to an artificial light source device for supplying light energy to a phosphorescent phosphor, and more specifically, a phosphorescent surface having the excitation spectrum of an ultraviolet wavelength in at least a part of the surface region (same as phosphorescent phosphor). The present invention relates to a phosphorescent phosphor excitation light source device in which an ultraviolet light corresponding to an excitation spectrum is irradiated on a phosphorescent surface using a phosphorescent ball, phosphorescent clothing, or other phosphorescent article provided with Note that the phosphorescent phosphor and the long persistence phosphor or phosphor are synonymous.

Conventionally, phosphorescent phosphor materials using an alkaline earth metal [M ^(II) ] aluminate [M ^(II) O · Al ₂ O ₃ ] as a parent crystal and a rare earth metal as an activator are known. (For example, see Patent Documents 1 and 2).
Japanese Patent No. 2543825 JP 7-11250 A

Further, a phosphorescent ball in which a phosphorescent layer is formed on the surface of a soccer ball using this type of phosphorescent phosphor material has been proposed (see, for example, Patent Document 3).
Japanese Patent Laid-Open No. 2006-25890

By the way, the phosphorescent phosphor (material) is so-called photoluminescence (PL), and an excitation light source that irradiates light having a wavelength corresponding to the excitation spectrum is required. Of course, it is only necessary to use sunlight, a lighting device, or other artificial light source (preferably an ultraviolet light source) (for example, refer to Patent Documents 4, 5 and 6 regarding the ultraviolet light source).

However, there is a limitation on the use time for sunlight, and for artificial light sources, a three-dimensional article such as a phosphorescent ball provided with a phosphorescent phosphor having an excitation spectrum of an ultraviolet wavelength (when the phosphorescent article is unacceptable) is irradiated. No body has been found to supply light energy to phosphorescent phosphors by irradiating the entire surface with ultraviolet light according to the excitation spectrum. (For example, refer to Patent Documents 7 and 8 regarding a surface light source and Patent Documents 9 and 10 regarding a backlight module, respectively).
