Abstract

A luminaire system having a lamp compartment and sterilization compartment permitting both illumination and the sterilizing of airborne bacteria. The sterilization compartment has one or more germicidal lamps to sterilize airborne bacteria when air is circulated through the luminaire system. The lamp compartment has one or more lamps to illuminate the desired outside environment away from the system.

Claims

1. An air purifying luminaire comprising:

a light fixture having a first compartment adjacent a second compartment, said first compartment containing one or more germicidal lamps concealed in said first compartment, and said second compartment containing one or more lamps illuminating the desired area away from said light fixture; and

a fixture inlet spaced from and in flow communication with a fixture outlet thereby forming a throughway passing adjacent said one or more germicidal lamps, whereby a cooling convection flow of air enters said light fixture through said fixture inlet and passes said one or more germicidal lamps concealed in said light fixture and exits said light fixture through said fixture outlet when said one or more germicidal lamps is in operation, thereby sterilizing said convection flow of air.

2. The air purifying luminaire as in claim 1 wherein said first compartment is positioned upwardly from said second compartment.

3. The air purifying luminaire as in claim 1 wherein said light fixture has a lower end and an upper end, wherein said air inlet is adjacent said lower end of said light fixture and said air outlet is adjacent said upper end of said light fixture.

4. The air purifying luminaire as in claim 1 wherein said throughway passes through said second compartment.

5. The air purifying luminaire as in claim 1 further includes one or more slots interconnecting said first compartment and said second compartment.

6. The air purifying luminaire as in claim 1 wherein said convection flow of air circulates through said fixture when said one or more lamps of said second compartment is in operation.

7. A luminaire system for air purification comprising:

a luminaire fixture having a lamp compartment and a germicidal lamp compartment, said germicidal lamp compartment containing one or more germicidal lamps;

said germicidal lamp compartment having one or more air inlet apertures connected by a throughway to one or more air outlet apertures, whereby air travels into said one or more air inlet apertures through said throughway and exits out of said germicidal lamp compartment through said one or more air outlet apertures;

said one or more germicidal lamps of said germicidal lamp compartment illuminates into said throughway within said luminaire fixture; and

one or more lamps of said lamp compartment illuminating away from said luminaire fixture to the desired outside environment.

8. The luminaire system as in claim 7 wherein said air travels by a cooling convection within said luminaire fixture.

9. The luminaire system as in claim 7 wherein said one or more germicidal lamp compartment is positioned substantially above said lamp compartment.

10. The luminaire system as in claim 7 wherein said lamp compartment includes a lens.

11. The luminaire system as in claim 7 wherein said throughway passes through said lamp compartment.

12. The luminaire system as in claim 7 further including a plurality of electronics in electrical communication with said one or more germicidal lamps of said germicidal lamp compartment or said one or more lamps of said lamp compartment.

13. A luminaire system comprising:

a lamp compartment in flow communication with a sterilization compartment, wherein said sterilization compartment includes one or more ultraviolet lamps, and said lamp compartment having one or more lamps illuminating the desired area away from said luminaire system; and

a system inlet in fluid communication with a system outlet thereby forming a throughway extending through said sterilization compartment and said lamp compartment, wherein a cooling convection flow of air enters into said system inlet and passes adjacent said one or more ultraviolet lamps of said sterilization compartment whereby said air is sterilized, and said sterilized air exits said luminaire system through said system outlet.

14. The luminaire system as in claim 13 wherein said one or more ultraviolet lamps are concealed within said sterilization compartment.

15. The luminaire system as in claim 14 wherein said sterilization compartment includes one or more baffles sufficiently reducing ultraviolet light emitted from said one or more ultraviolet lamps from leaking outwardly away from said luminaire system.

16. The luminaire system as in claim 13 wherein each of said system inlet and said system outlet includes one or more slots.

17. The luminaire system as in claim 13 wherein said system inlet is proximate a lower end of said system and said system outlet is proximate an upper end of said system.

18. The luminaire system as in claim 13 is a wall mounted light fixture.

19. The luminaire system as in claim 13 wherein said throughway is defined by one or more apertures interconnecting said lamp compartment with said sterilization compartment.

20. The luminaire system as in claim 13 wherein said sterilization compartment is located substantially above said lamp compartment.
