Ultraviolet discharge lamp apparatuses with one or more reflectors
First Claim
1. An apparatus for disinfecting a room, comprising:
- a discharge lamp configured to emit ultraviolet light;
a housing encasing the discharge lamp, wherein a lower boundary of the housing comprises a fan for drawing air into the housing, and wherein an upper boundary of the housing comprises an ozone filter;
a power circuit configured to operate the discharge lamp;
a support structure supporting the discharge lamp; and
a reflector assembly disposed above and over an uppermost surface of the discharge lamp, wherein an underside surface of the reflector assembly comprises a reflector dimensionally configured and slanted relative to a horizontal plane of the apparatus to redirect light emitted from the discharge lamp downwardly 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 reflector is spaced from the discharge lamp, and wherein the housing is affixed to the support structure and to the reflector assembly.

Abstract
Apparatuses are disclosed which include a discharge lamp configured to emit ultraviolet light, a power circuit configured to operate the discharge lamp, and a reflector system configured to redirect ultraviolet light emitted from the discharge lamp. In some embodiments, the apparatuses include a support structure containing the power circuit and supporting the discharge lamp. In some of such embodiments, the reflector system is configured to redirect ultraviolet light propagating away from the support structure to a region exterior to the apparatus and which is between approximately 2 feet and approximately 4 feet from a floor of a room in which the apparatus is arranged. In other embodiments, the reflector system may be additionally or alternatively configured to redirect ultraviolet light propagating away from the support structure to encircle an exterior surface of the apparatus. In any case, the reflector system may, in some embodiments, include a repositionable reflector.

9. An apparatus, comprising:
-
a discharge lamp configured to emit ultraviolet light; a power circuit configured to operate the discharge lamp; a reflector arranged to redirect ultraviolet light emitted from the discharge lamp, wherein the reflector and the discharge lamp comprise a moveable assembly within the apparatus; a support structure supporting the moveable assembly; a controller having program instructions which are executable by a processor for moving the moveable assembly while the discharge lamp is emitting ultraviolet light such that the reflector and discharge lamp are repositioned within the apparatus relative to the support structure; an additional moveable assembly within the apparatus surrounding the discharge lamp, wherein the additional moveable assembly comprises the reflector and an optical filter opposing the reflector; and a central processing unit comprising program instructions which are executable by a processor for rotating or oscillating the additional moveable assembly within the apparatus relative to the discharge lamp while the discharge lamp is emitting ultraviolet light. - View Dependent Claims (10)
