A light fixture with co-formed plenum component is disclosed. Embodiments of the invention provide troffer-style recessed solid state fixture using a highly reflective plastic reflector. In at least some embodiments, the plastic reflector can meet the additional requirements placed on mechanical components exposed to the space above the ceiling plane in plenum return ceiling applications. Example embodiments include a light fixture with an LED light source and a reflector that is coextruded from a plenum rated substrate and a reflective material, for example, a plenum rated plastic substrate and a diffuse, white reflective material. In some embodiments, the plenum rated substrate includes polyetherimide, a polyphenylene ether/polystyrene blend, polycarbonate, polycarbonate copolymer, or a combination of the foregoing. |
