Abstract:
A laser-activated remote phosphor (LARP) target comprising a substrate 8114), a dichroic filter(120) disposed on the substrate, a phosphor converter (102) disposed on the dichroic filter, and an aperture structure (230) disposed on the phosphor converter. The phosphor converter comprises a luminescent material that at least partially converts a primary laser pump light (110) into a secondary light (108) having a different peak wavelength. The dichroic filter substantially transmits the primary laser pump light and substantially reflects the secondary light. The aperture structure covers the lighting emitting surface except for an aperture (240) in the aperture structure whereby a substantial portion of secondary light passes through the aperture in the aperture structure for coupling into an optical system.
