<P>PROBLEM TO BE SOLVED: To provide a fluorescent substance-dispersed glass which can be produced by using a sol-gel process and emitting light with color mixture light of a uniform color tone despite the difference of directivity between a primary light emitted by an LED light emitting element and a secondary light emitted by a fluorescent substance, and a method for producing the same. <P>SOLUTION: The method for producing a fluorescent substance-dispersed glass makes bubbles 4 of a predetermined size having a function for scattering light remain with a predetermined density by controlling a sintering period and a sintering temperature of a dried gel substance, and the fluorescent substance-dispersed glass 1 is made to emit securely a color mixture light (tertiary light R3) whose color tone is uniform even when it is viewed from any place by dispersing a primary light R1 emitted by an LED light emitting element 5 and a secondary light R2 emitted by a fluorescent substance 3 and emitting broadly the tertiary light R3 in which the primary light and the secondary light are uniformly color-mixed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
