Classification: CPC H  F | IPC F  H

Claim 23:
24. A laser diode excited phosphor comprising:
a single-layered integrated composite structure comprising:
a fluoride phosphor matrix configured to emit light at a first wavelength comprising orange or red light,
a plurality of additional phosphor particles homogeneously integrated within the fluoride phosphor matrix, the plurality of additional phosphor particles configured to emit light at a second wavelength that is different from the first wavelength, the second wavelength comprising colors cyan, green, or yellow light,

wherein the single-layered integrated composite structure is substantially free of an organic binder,
wherein the single-layered integrated composite structure is configured to be disposed adjacent to a laser diode excitation light source that emits light of a third wavelength that is different from the first and second wavelengths, the third wavelength comprising blue light, and
wherein the single-layered integrated ceramic structure is configured to modify the light of the third wavelength passing therethrough to emit white light, wherein the white light includes a first amount of relative photon emission of the single-layered integrated composite structure and a second amount of relative photon emission of the laser diode excitation light source, the first amount being greater than the second amount, and the first amount including a third amount of relative photon emission of the fluoride phosphor matrix and a fourth amount of relative photon emission of the distinct additional phosphor particles, the fourth amount being greater than the third amount.
