Some embodiments of the present invention provide a combination lighting and ventilating apparatus for installation in a structure. The apparatus can include a main housing having a first aperture that defines a ventilating inlet and a lighting outlet, a lamp housing recessed within the main housing, having first and second apertures spaced a distance from one another, and having a portion that extends outside of the main housing, and a lamp recessed within the lamp housing and the main housing. In some embodiments, the apparatus further includes a fan positioned to draw air into and through the first aperture of the lamp housing, around the lamp, and through the second aperture of the lamp housing. In another aspect of the invention, a method of lighting and ventilating a room using a combination lighting and ventilating apparatus is provided.

Lighting and ventilating apparatus and method

The invention provides a ventilating and heating apparatus for installation in a building structure. In some embodiments, the apparatus includes a main housing in which is located a ventilating fan assembly and a heater fan assembly having a heater and a discharge duct terminating in a discharge outlet, wherein the heater is located within and connected to the discharge duct of the heater fan assembly. The heater can be shielded from the discharge outlet by at least one interior wall of the discharge duct. In some embodiments, the discharge duct can have a tapered portion approaching the discharge outlet. In some embodiments, a discharge aperture of a cover is recessed with respect to the discharge outlet of a fan housing.

Ventilating and lighting assembly

Ventilating and heating assembly

A damper flap and duct connector assembly for controlling air flow through a ventilation system includes a damper flap pivotably mounted to a duct connector. The connector connected to a ventilator has an air flow opening disposed in its center and a cylindrical ring extending from the outer edge that is connected to a ventilation duct. The connector also includes a pair of spaced, opposed brackets disposed above one edge of the air flow opening. The damper flap includes a generally rectangular plate forming the body of the flap that rests over the air flow opening in the connector to selectively open and close the opening, and a pair of arms extending outwardly from one edge of the plate. The arms are rolled towards the plate to form a pair of mounting tubes separated by a flexible portion of the plate. The length between opposite ends of the tubes is longer than the length between the opposed brackets. Due to the ability of the plate to flex, this distance may be shortened to allow the sleeves to be inserted into mounting openings in the brackets to pivotably retain the damper flap on the connector.

A pair of air deflectors attached to the outlet opening of a blower assembly housed within a ventilator housing to accommodate multiple size outlets in the ventilator housing of a ventilation system. The air deflectors include a front portion for attachment to a sidewall flange extending outwardly from the outlet opening of the blower assembly, a transition portion extending rearwardly and inwardly from one side of the front portion, and a flange extending rearwardly from the transition portion for attachment to a sidewall of the blower assembly. The air deflectors attached to the outlet opening of the blower assembly increase air flow, decrease air turbulence and decrease noise within the ventilation system.
