Abstract: A lighting device (100) includes a housing (104) enclosing a housing interior (108), a light source (132), a light converter (136), and a color tuning device. The light source is configured for emitting a primary light beam of a primary wavelength (140) through the housing interior. The light converter includes a luminescent material (144) facing the housing interior and configured for emitting secondary light (156, 158) of one or more wavelengths different from the primary wavelength, in response to excitation by the primary light beam. The housing includes a light exit (124) for outputting a combination of primary light and secondary light. The color tuning device is configured for adjusting a position of the primary light beam relative to the luminescent material.

Abstract: A fluorescent lamp includes a glass envelope that is light transmitting. There is means for providing a discharge inside the envelope. A discharge-sustaining fill of mercury and an inert gas is sealed inside the envelope. An underlying phosphor-containing layer is disposed inside the envelope. The underlying layer includes yttrium vanadate phosphor. A protective phosphor-containing layer is disposed over the underlying layer at a location that is more distal from the glass than the underlying layer.
