Abstract: Embodiments of the invention provide an illumination grille assembly comprising a frame and a ventilation grille coupled to the frame, and a plurality of light-emitting diodes coupled with the frame and at least partially covered with a light transparent cover. Some embodiments of the invention provide a lighting and ventilating system including a main housing including an inlet through which air can be received within the main housing and an outlet through which the air can exit the main housing. A blower assembly can be supported in the main housing and it can be operable to generate a flow of air. In some embodiments, an illumination grille assembly can be coupled to the main housing to allow fluid to flow through the illumination grill assembly to the main housing. In some embodiments, the set of illumination devices can be configured and arranged to emit light through the light transparent cover.

Abstract: Embodiments of the invention provide a lighting and ventilating system including a main housing. The main housing can include an inlet through which air can be received within the main housing and an outlet through which the air can exit the main housing. A fan wheel can be supported in the main housing and it can be operable to generate a flow of air. A grille can be coupled to the main housing and the grille can comprise at least one aperture. The system can include a plate coupled to the grille and the plate can include a recess. Also, a set of illumination devices can be at least partially disposed within the recess.

Abstract: A damper assembly having a main body defining a continuous fluid path extending between a first opening and a second opening and a damper door rotatable within the main body to control the flow of fluid through the main body. The main body including an engagement edge extending circumferentially on an inner surface of the main body. The damper door can be rotated relative to the main body to sealingly engage an outer edge of the damper door with the engagement edge. The engagement edge of the main body can be oriented on the inner surface such that the surface area of the outer edge such that engagement of the engagement edge gradually increases as the damper door is rotated to seal the damper door to the main body.
