Abstract
A luminaire including a light engine and a dichroic filter are provided. The light engine emits a light beam including light from a pump laser and light from a phosphor illuminated by the pump laser. The dichroic filter includes a first band pass region having a transmissivity less than 70%, varying by at most +/−10% that extends from a first wavelength shorter than the light from the pump laser to a second wavelength at least 5 nanometers longer than a 50% intensity of a longest wavelength of the light from the pump laser. A band reject region has a second predefined maximum transmissivity less than 10% in a range of longer wavelengths, rejecting at least some shorter wavelengths of the light from the phosphor. A second band pass region has a third predefined maximum transmissivity in a range of still longer wavelengths.
