Abstract:
1. A lighting device, which comprises a single radiation source, a first wavelength converting member, a second wavelength converting member, and a third wavelength converting member, wherein: said first wavelength converting member absorbs at least a portion of the electromagnetic radiation originated from said single radiation source, and emits a first electromagnetic radiation with peak wavelength λ said second wavelength converting member absorbs at least a portion of the electromagnetic radiation originated from said single radiation source, and emits a second electromagnetic radiation with peak wavelength λ said third wavelength converting member absorbs at least a portion of the electromagnetic radiation originated from said single radiation source and emits a third electromagnetic radiation with peak wavelength λ said first wavelength converting member is substantially isolated from the irradiation of the second electromagnetic radiation, wherein said lighting device further includes a first selective reflector located between said first and second wavelength converting member, and a second selective reflector between said second wavelength converting member and said third wavelength converting member, wherein said first selective reflector is configured to selectively reflect radiation capable of being absorbed by said first wavelength converting member.
