Abstract
An LED reflector lamp is provided wherein the lamp has a concave reflector substantially symmetrically arrayed about an axis, the reflector further having a focus and a bottom. A subassembly is coaxially aligned with said axis and comprises a light guide having a proximal end positioned outside of said reflector and a distal end positioned within said reflector at said focus. A first light source comprising at least one light emitting diode (LED) is positioned at said proximal end and operable to emit a first radiation when energized. A second light source comprising at least one phosphor is positioned at said distal end and operable to emit a second radiation having a different wavelength than said first radiation when energized by said first radiation from said first light source.
