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 ventilating 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, the grille including a region and comprising a plurality of apertures substantially around the perimeter of the region;

a lamp housing coupled to the region, the lamp housing including a set of illumination devices;

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;

a plate coupled to the grille, the plate including an aperture having a textured surface; and

a lens coupled to the plate so that the lens is adjacent to the set of illumination devices.

2. The lighting and ventilating system of claim 1, and further comprising a pilot light.

3. The lighting and ventilating system of claim 1, wherein the set of illumination devices comprises light-emitting diodes.

4. The lighting and ventilating system of claim 1, wherein the plurality of apertures are located adjacent the set of illumination devices.

5. The lighting and ventilating system of claim 1, wherein the system is substantially controlled by a motion-sensing monitor.

6. The lighting and ventilating system of claim 1, wherein the set of illumination devices are activated when a space in which the system is installed substantially lacks illumination.

7. The lighting and ventilating system of claim 1, wherein the set of illumination devices substantially illuminate the plate.

8. The lighting and ventilating system of claim 1, wherein the plate includes a tint.

9. The lighting and ventilating system of claim 1, wherein the set of illumination devices can radiate different intensities of illumination.

10. A lighting and ventilating 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, the inlet being disposed substantially perpendicular to the outlet;

a grille coupled to the main housing, the grille including a region and comprising a plurality of apertures substantially around the perimeter of the region and disposed adjacent a plurality of light-emitting diodes;

a plate coupled to the grill, the plate including a plate aperture having a textured surface;

a lens supported by the plate and disposed adjacent the plurality of light-emitting diodes; and

a fan wheel supported in the main housing to generate a flow of air past the lens, the grille and the plurality of light-emitting diodes, into the inlet, past the fan wheel and out the outlet.

11. The lighting and ventilating system of claim 10, and further comprising a pilot light.

12. The lighting and ventilating system of claim 10, and further comprising a second set of illumination devices.

13. The lighting and ventilating system of claim 10, wherein the light-emitting diodes are activated when a space in which the system is installed substantially lacks illumination.

14. The lighting and ventilating system of claim 10, wherein the system is substantially controlled by a motion-sensing monitor.

15. A lighting and ventilating 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, the inlet being disposed substantially perpendicular to the outlet;

a grille coupled to the main housing, the grille comprising a plurality of apertures disposed adjacent a plurality of light-emitting diodes;

a lens coupled to the grill and disposed adjacent the plurality of light-emitting diodes; and

a fan wheel supported in the main housing to generate a flow of air past the lens, the grille and the plurality of light-emitting diodes, into the inlet, past the fan wheel and out the outlet;

a plate including a plate aperture having a textured surface.

16. The lighting and ventilating system of claim 15, wherein the plate includes a tint.
