US 2018/0003406 A1 · LAMINAR FLOW DIFFUSER WITH INTEGRATED LIGHTING

Abstract

A laminar flow diffuser with integrated lighting has a frame for supporting an air plenum and a lower housing. The air plenum receives conditioned air from a source of conditioned. The lower housing is attached to the bottom of the plenum. An aperture plate damper installed below the top plenum regulates the flow of air from the plenum through the laminar flow diffuser. A clear or translucent engineered, fire rated polymer perforated diffuser face forms the outlet from the lower housing to the room below. LED strips are positioned around the inside periphery of the lower housing. A light guide is installed adjacent the LED lighting strips to spread the light across the area of the perforated diffuser face.
