Classification: CPC H  F | IPC F  H

Claim 21:
22. A laser diode-based lighting component comprising:
a laser diode (LD) configured to generate a first wavelength comprising blue light; and
a single integrated phosphor composite structure positioned adjacent to the LD, the single integrated phosphor composite ceramic structure comprising:
a transparent or translucent fluoride phosphor ceramic configured to emit light at a second wavelength comprising orange or red light when irradiated by the first wavelength; and
a plurality of distinct phosphor particles homogeneously integrated within the fluoride phosphor ceramic, the distinct phosphor particles configured to emit light at a third second wavelength that is different from the second wavelength when irradiated by the first wavelength, the third wavelength comprising colors cyan, green, or yellow light,

wherein a first amount of relative photon emission of the single-layered phosphor composite structure and a second amount of relative photon emission of the laser diode together generate white light, 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 ceramic and a fourth amount of relative photon emission of the distinct additional phosphor particles, the fourth amount being greater than the third amount.
