A lighting device, comprising: lighting means comprising an active light source operable to emit light composed of a plurality of wavelengths, the active light source comprising at least one white light emitting diode (104, 404, 504) formed from at least one blue light emitting diode, LED, with one or more phosphor layers provided either on the blue LED or on a lens or window through which blue light from the LED will pass, said white light emitting diode (104, 404, 504) being operable to emit white light composed of the plurality of wavelengths; reflective filtering means (108, 408, 508) comprising at least one reflective filter that substantially passes light of a first set of wavelengths in the plurality of wavelengths and that substantially returns light of a second set of wavelengths in the plurality of wavelengths, the at least one reflective filter (108, 408, 504) positioned in an optical path between the at least one white light emitting diode (104, 404, 504) and an exterior of the lighting device to filter the light before the light reaches the exterior of the lighting device; and; characterized by a wavelength shifter (106, 406, 506) comprising a phosphor material, for shifting at least some wavelengths of light of the second set of wavelengths emitted by the at least one white light emitting diode (104, 404, 504) and returned by the at least one reflective filter means (108, 408, 508) the wavelength shifter (106, 406, 506) positioned and oriented to receive at least some of the light emitted by the at least one white light emitting diode (104, 404, 504) and to receive at least some of the second set of wavelengths returned from the at least one reflective filter (108, 408, 508) and in response emit light at a shifted wavelength toward an optical exit of the lighting device. lighting means comprising an active light source operable to emit light composed of a plurality of wavelengths, the active light source comprising at least one white light emitting diode (104, 404, 504) formed from at least one blue light emitting diode, LED, with one or more phosphor layers provided either on the blue LED or on a lens or window through which blue light from the LED will pass, said white light emitting diode (104, 404, 504) being operable to emit white light composed of the plurality of wavelengths; reflective filtering means (108, 408, 508) comprising at least one reflective filter that substantially passes light of a first set of wavelengths in the plurality of wavelengths and that substantially returns light of a second set of wavelengths in the plurality of wavelengths, the at least one reflective filter (108, 408, 504) positioned in an optical path between the at least one white light emitting diode (104, 404, 504) and an exterior of the lighting device to filter the light before the light reaches the exterior of the lighting device; and; characterized by a wavelength shifter (106, 406, 506) comprising a phosphor material, for shifting at least some wavelengths of light of the second set of wavelengths emitted by the at least one white light emitting diode (104, 404, 504) and returned by the at least one reflective filter means (108, 408, 508) the wavelength shifter (106, 406, 506) positioned and oriented to receive at least some of the light emitted by the at least one white light emitting diode (104, 404, 504) and to receive at least some of the second set of wavelengths returned from the at least one reflective filter (108, 408, 508) and in response emit light at a shifted wavelength toward an optical exit of the lighting device.
