    Abstract: A photoluminescent material has the characteristic of a long photoluminescence decay and has the general composition Ca3-x-m-nAxSc2-yMySi3-zEzO12:mCe3+,nMn2+, where A is at least one divalent cation including Sr, Ba or a combination of monovalent and trivalent cations including combinations of Li, Na, K, B, Al and Ga; M is at least one trivalent cation including Al, Ga, or a divalent cation including Mg, E is a combination of a trivalent and a pentavalent cation including B, Al, Ga, N and P, or a combination of monovalent and trivalent cations including Li, Na, K, B, Al, Ga, N and P. The A cation replaces Ca; the M cation replaces Sc, and E replaces Si. This Mn and Ce doped phosphor emits in the yellow to green with a peak at around 510 and/or 560 and 690 nm. The phosphor material has applications in LED illumination systems.

    Abstract: A solid-state lamp is described that includes a first light emission zone and a second light emission zone, where the first light emission zone is longitudinally spaced apart from the second light emission zone. The light emission zones comprise a photoluminescence wavelength conversion component and a solid state light emitting device. The lamp comprises a lower body, a central body, and an upper duct, where the central body, and the upper duct together define at least one passageway/duct for thermal airflow.

    Abstract: A light emitting device comprises: a solid-state light emitter which generates blue excitation light with a dominant wavelength from 440 nm to 470 nm; a yellow to green photoluminescence material which generates light with a peak emission wavelength from 500 nm to 575 nm; a broadband orange to red photoluminescence material which generates light with a narrowband peak emission wavelength from 580 nm to 620 nm; and a narrowband red manganese-activated fluoride phosphor which generates light with a peak emission wavelength from 625 nm to 635 nm. The device generates white light with a spectrum having a broad emission peak from about 530 nm to about 600 nm and a narrow emission peak and wherein the ratio of the peak emission intensity of the broad emission peak to the peak emission intensity of the narrow emission peak is at least 20%.
