  • Patent number: 10514150
    Abstract: A reflector assembly for a solid-state luminaire is disclosed. The disclosed reflector assembly may be configured, in accordance with some embodiments, to be disposed over a given printed circuit board (PCB) of a host luminaire such that emissions of emitters populated over that PCB are reflected out of the luminaire via the reflector assembly. In some embodiments, the reflector assembly may be formed from one or more reflective members, which may be generally bar-shaped or cup-shaped, or other example configurations. In some other embodiments, the reflector assembly may be formed from a bulk body having one or more reflective cavities formed therein. The particular configuration of a given reflective member or reflective cavity, as the case may be, of the reflector assembly, as well as the particular arrangement thereof for a host luminaire, may be customized as desired for a given target application or end-use.
