Abstract

A phosphor based lamp includes a phosphor material and an excitation source which may be a laser or an LED or both. Preferably the lamp includes a recycling collar to reflect and recycle high angle light to increase brightness. Preferably when the excitation source is a laser a beam splitter redirects the laser beam to direct the laser beam through the recycling collar aperture onto the phosphor material. Light emitted by the phosphor material which exits the aperture passes through the beam splitter as the output of the lamp. Alternatively lenses are used to redirect the laser beam around the recycling collar towards the phosphor material. Preferably a plurality of excitation lasers are disposed around the recycling collar and aimed either to direct their outputs onto the phosphor material or toward an opposing wall where the outputs are reflected onto the phosphor material.
