摘要： A white light source and method of use thereof, wherein control of daily rhythm and pleasant lighting can be realized. Amounts of stimulation light emitted from a white light source to the intrinsically photosensitive retinal ganglion cells (ipRGCs) and visual cells of the L cone and M cone, are defined as a melanopic irradiance, an L-cone opic irradiance, and an M-cone opic irradiance, respectively; a ratio of the amounts of the stimulation light is expressed by formula (1); and A is the ratio corresponding to the emission spectrum of the white light source, and B is the ratio corresponding to the radiation spectrum of a black body having the same color temperature as the white light source, an amount of stimulation light emitted to the ipRGC is quantitatively changed by changing the emission intensity of the white light source satisfying formula (2).
Melanopic irradiance/(L-cone opic irradiance+M-cone opic irradiance) (1)

摘要： The present disclosure relates to a lighting component which may comprise a light emitting diode (LED) or laser diode (LD) for generating at least one of blue light or ultraviolet light. A fluoride phosphor matrix may be included, which may be consolidated into a phosphor ceramic structure including at least one of a transparent fluoride ceramic structure or a translucent fluoride ceramic structure, and positioned adjacent to the LED or LD. The phosphor ceramic structure generates at least one of red or orange light when irradiated by the light emitted from the LED or LD. The phosphor ceramic structure exhibits reduced thermal quenching relative to a fluoride particulate structure irradiated by the LED or LD.
