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.

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 a plurality of apertures and a second set of illumination devices. The system further can include a lamp housing coupled to the grille, the lamp housing can include a first set of illumination devices. Also, a plate can be coupled to the grille so that the plate is adjacent to the second set of illumination devices.

Abstract: A ventilation unit for installation in a ventilation system. The ventilation unit can include a motor coupled to a fan element and a power source. The ventilation unit can also include a calibration module having one of a voltage and current regulator for adjusting the performance of the ventilation unit based on at least one characteristic of the ventilation system.

Abstract: The present invention provides an exhaust fan including a ventilation grille having a plurality of louvers extending across an exterior face of the grille. Two of the louvers can define an opening and can be oriented such that the interior of the fan is obscured from view of a person through the opening, when the person is positioned in the room such that the person's eyes are outside an area of the room defined by a first reference plane oriented at an angle of less than 25 degrees with respect to a second reference plane and intersecting the second reference plane along a horizontal reference line and a third reference plane oriented at an angle of less than 25 degrees with respect to the second reference plane and intersecting the second reference plane along the horizontal line.
