Abstract

Apparatuses are disclosed having an ultraviolet lamp and a reflector system arranged to project light emitted from the lamp to a region 2-4 feet from a floor of a room in which the apparatus is arranged. The apparatuses include a mobile carriage with wheels and one or more compartments underneath the lamp that hold operational components for the apparatus. The apparatuses are configured such that the lamp is not moveable beyond vertical planes aligned with a casing of the carriage. In some cases, a lowermost surface of the lamp is arranged at an elevation substantially level with or above an upper surface of the casing that is at least 36 inches above the floor of the room. In addition or alternatively, the carriage may include a handle exterior to its casing having an uppermost surface arranged at substantially the same level or lower than a lowermost surface of the lamp.

Claims

1. An apparatus, comprising:

a germicidal lamp configured to emit ultraviolet light, wherein the germicidal lamp is arranged lengthwise substantially parallel to a horizontal plane of the apparatus;

a mobile carriage supporting the germicidal lamp, wherein the mobile carriage comprises;

one or more compartments underneath said arranged germicidal lamp, wherein the one or more compartments hold operational components for the apparatus;

a casing enclosing the one or more compartments, wherein the apparatus is configured such that the germicidal lamp is not moveable beyond vertical planes aligned with the casing when the germicidal lamp is supported by the mobile carriage; and

wheels along a bottom of the mobile carriage to affect portability of the apparatus; and

a reflector system arranged in the apparatus such that ultraviolet light emitted from the germicidal lamp is projected to a region exterior to the apparatus between approximately 2 feet and approximately 4 feet from a floor of a room in which the apparatus is arranged, wherein the apparatus is configured such that a reflector of the reflector system is moveable relative to the mobile carriage.

2. The apparatus of claim 1, further comprising a housing surrounding the germicidal lamp, wherein one or more sidewalls of the housing are transparent to ultraviolet light, and wherein the housing is arranged exterior to the mobile carriage.

3. The apparatus of claim 1, wherein the reflector system comprises a reflector above the germicidal lamp.

4. The apparatus of claim 1, wherein the reflector system comprises a reflector below the germicidal lamp.

5. The apparatus of claim 1, wherein the reflector system comprises a reflector above the germicidal lamp and a reflector below the germicidal lamp.

6. The apparatus of claim 1, comprising:

an automated actuator for moving the reflector relative to the mobile carriage; and

a controller for activating the automated actuator such that the reflector is repositioned relative to the mobile carriage while the germicidal lamp is emitting ultraviolet light.

7. The apparatus of claim 6, wherein the controller is for activating the automated actuator to periodically move the reflector while the apparatus is in operation.

8. The apparatus of claim 1, wherein the apparatus is configured such that the reflector is not moveable beyond the vertical planes aligned with the casing.

9. An apparatus, comprising:

a germicidal lamp configured to emit ultraviolet light;

a mobile carriage disposed beneath the germicidal lamp, wherein the mobile carriage comprises;

a casing having an uppermost surface at least approximately 36 inches above a floor of a room in which the apparatus is arranged, wherein a lowermost surface of the germicidal lamp is arranged at substantially the same level or above the uppermost surface of the casing, and wherein the apparatus is configured such that the germicidal lamp is not moveable beyond vertical planes aligned with the casing when the germicidal lamp is operationally arranged in the apparatus; and

wheels along a bottom of the mobile carriage to affect portability of the apparatus; and

a reflector system arranged in the apparatus such that ultraviolet light emitted from the germicidal lamp is projected to a region exterior to the apparatus which is between approximately 2 feet and approximately 4 feet from the floor, wherein the apparatus is configured such that a reflector of the reflector system is moveable relative to the mobile carriage.

10. The apparatus of claim 9, further comprising a housing surrounding the germicidal lamp, wherein one or more sidewalls of the housing are transparent to ultraviolet light, and wherein the housing is arranged exterior to the mobile carriage.

11. The apparatus of claim 9, wherein the reflector system is arranged in the apparatus such that an entire vertical extent of the region between approximately 2 feet and approximately 4 feet from the floor of the room is exposed to ultraviolet light when the germicidal lamp is emitting light.

12. The apparatus of claim 9, wherein the germicidal lamp is arranged lengthwise substantially parallel to a horizontal plane of the apparatus.

13. The apparatus of claim 9, wherein the germicidal lamp is arranged lengthwise substantially perpendicular to a horizontal plane of the apparatus.

14. The apparatus of claim 9, wherein the germicidal lamp is arranged at an angle between 0°

and 90°

relative to a horizontal plane of the apparatus.

15. The apparatus of claim 9, wherein the reflector system comprises a reflector above the germicidal lamp.

16. The apparatus of claim 9, wherein the reflector system comprises a reflector below the germicidal lamp.

17. The apparatus of claim 9, wherein the reflector system comprises a reflector above the germicidal lamp and a reflector below the germicidal lamp.

18. The apparatus of claim 9, wherein the apparatus is configured such that the reflector is not moveable beyond the vertical planes aligned with the casing.

19. The apparatus of claim 9, wherein the apparatus is configured such that the germicidal lamp may be repositioned in and out of a recess of the mobile carriage.

20. The apparatus of claim 9, comprising:

an automated actuator for moving the germicidal lamp; and

a controller for activating the automated actuator such that the germicidal lamp is repositioned within the apparatus relative to the mobile carriage while the germicidal lamp is emitting ultraviolet light.

21. The apparatus of claim 9, wherein the germicidal lamp and a reflector of the reflector system comprise a moveable assembly within the apparatus.

22. An apparatus, comprising:

a germicidal lamp configured to emit ultraviolet light;

a mobile carriage supporting the germicidal lamp, wherein the mobile carriage comprises;

one or more compartments underneath the germicidal lamp, wherein the one or more compartments hold operational components for the apparatus;

a casing enclosing the one or more compartments, wherein the apparatus is configured such that the germicidal lamp is not moveable beyond vertical planes aligned with the casing when the germicidal lamp is supported by the mobile carriage;

a push/pull handle arranged exterior to the casing, wherein an uppermost surface of the push/pull handle is arranged at substantially the same level as an uppermost surface of the germicidal lamp or at an elevation lower than the uppermost surface of the germicidal lamp; and

wheels along a bottom of the mobile carriage to affect portability of the apparatus; and

a reflector system arranged in the apparatus such that ultraviolet light emitted from the germicidal lamp is projected to a region exterior to the apparatus which is between approximately 2 feet and approximately 4 feet from a floor of a room in which the apparatus is arranged, wherein the apparatus is configured such that a reflector of the reflector system is moveable relative to the mobile carriage.

23. The apparatus of claim 22, wherein the apparatus is configured such that the reflector is not moveable beyond the vertical planes aligned with the casing.
