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 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.

Claims

1. A lighting and ventilation system, comprising:

a main housing including an inlet through which air is received within the main housing and an outlet through which the air exits the main housing;

a fan wheel supported in the main housing and operable to generate a flow of air;

a lamp housing including a first set of illumination devices;

a grille coupled to the main housing, the grille defining a lamp aperture and including a second set of illumination devices, wherein the lamp housing is coupled to the grille substantially adjacent the lamp aperture.

2. The lighting and ventilation system of claim 1, wherein at least one of the first set of illumination devices and the second set of illumination devices comprises LEDs.

3. The lighting and ventilation system of claim 1, wherein the second set of illumination devices is operable independently of the first set of illumination devices.

4. The lighting and ventilation system of claim 1, wherein the second set of illumination devices comprises a lighting strip supported by an annular structure positioned on the grille.

5. A ventilation and illumination system, comprising:

a main housing including an inlet through which air is received within the main housing and an outlet through which the air exits the main housing;

a grille coupled to the main housing over the inlet of the main housing, the grille including an annular structure, the grille defining a plurality of apertures arranged across the inlet for receiving a flow of air;

a lighting strip supported by the annular structure and comprising a set of LEDs;

a lens is coupled to the grille, wherein the lens is positioned on the grille to extend over the set of LEDs; and

a fan wheel supported in the main housing and operable to generate a flow of air into the grille, then into the inlet, past the fan wheel, and through the outlet.

6. The ventilation and illumination system of claim 5, wherein the lighting strip extends around a region of the grille.

7. The ventilation and illumination system of claim 6, wherein the annular structure extends around the region of the grille.

8. The ventilation and illumination system of claim 6, wherein at least one of the plurality of apertures is positioned within the region.

9. The ventilation and illumination system of claim 5, wherein the set of LEDs are coupled to at least one electrical connector.

10. The ventilation and illumination system of claim 9, wherein the at least one electrical connector is operably connected to at least one electrical component located in the main housing.

11. The ventilation and illumination system of claim 9, wherein the at least one electrical connector is operably connected to a user interface for receiving at least one command for operating the set of LEDs.

12. The ventilation and illumination system of claim 5, wherein the set of LEDs, comprises:

at least one first LED operable at a first brightness; and

at least one second LED operable at a second brightness;

wherein the second brightness has a lower intensity than the first brightness.

13. The ventilation and illumination system of claim 12, wherein the at least one first illumination device and the at least one second LED are operable concurrently.

14. The ventilation and illumination system of claim 12, wherein the at least one illumination device and the at least one second LED are operable sequentially.

15. The ventilation and illumination system of claim 5, further comprising:

a controller operably connected to the set of illumination devices;

wherein the controller is configured to operate the set of illumination devices at a first brightness and a second brightness, wherein the second brightness has a lower intensity than the first brightness.

16. The ventilation and illumination system of claim 5, further comprising:

a third illumination device offset from the center region.

17. The ventilation and illumination system of claim 16, further comprising:

a controller operably connected to the third illumination device;

wherein the controller is configured to operate the third illumination device at a first color and a second color.
