Self cooling, magnetically connected fixtures for large area directional and isotropic solid state lighting panels
Reflector designs for a large area panel light source create induced draft cooling means adjacent to the panel light source. The panel light source has a wavelength conversion element on a solid-state light source for emitting light of a first and second wavelength to form a broader emission spectrum of light from the panel light source.

Lighting device and projector
A lighting device includes a light source that emits a first light flux of a first wavelength band, a fluorescence light emitting element including a phosphor layer which produces, when excited by light of the first wavelength band, light of a second wavelength band, a polarization separation element that has a polarization separation function for light of the first wavelength band and transmits or reflects light of the second wavelength band, a retardation film disposed in an optical path between the polarization separation element and the phosphor layer, a first reflector disposed in an optical path between the retardation film and the phosphor layer, and a second reflector that reflects the light produced by the phosphor layer. The first reflector reflects part of the first light flux toward the polarization separation element, and transmits the other part of the first light flux toward the phosphor layer..
