Ultraviolet Discharge Lamp Apparatuses with One or More Reflectors
First Claim
1. An apparatus for disinfecting a room, comprising:
- a germicidal lamp;
a power circuit configured to operate the germicidal lamp;
a base supporting the germicidal lamp; and
a reflector assembly disposed above the germicidal 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 germicidal 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, and wherein the reflector is spaced from the germicidal lamp; and
a housing encasing the germicidal lamp, wherein the housing is affixed directly to the base and directly 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.

19. An apparatus for disinfecting a room, wherein the apparatus comprises:
-
a single discharge lamp configured to emit ultraviolet light; a support structure supporting a lower end of the single discharge lamp, wherein an upper end of the single discharge lamp extends above the uppermost surface of the support structure; a power circuit disposed within the support structure and configured to operate the single discharge lamp; circuitry connecting the power circuit to electrical contacts at the lower end of the single discharge lamp; and a reflector assembly disposed over an upper end of the single discharge lamp, wherein an underside surface of the reflector assembly comprises a reflector, and wherein an outer peripheral edge of the reflector is horizontally spaced from a vertical plane comprising a closest exterior sidewall surface of the single discharge lamp by a distance greater than three times a width of the single discharge lamp. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
