Abstract
A hand-held germicidal UV lamp includes housing for a UV light source and an aperture for allowing the transmission of UV light. A safety switch is provided on the housing which can be moved by an activation tool. A cover is provided over the switch having an opening for accessing the switch. The opening is sized so that a human finger cannot pass through the opening and move the switch. A light shield may be provided which surrounds the aperture and limits transmission of UV light.
Claims22
A germicidal UV lamp, comprising:
- a. a housing, the housing having a UV light source therein and having at least one aperture allowing the passage of UV light out of the housing;
- b. a safety switch on the housing for activating the light source, having a tool engaging portion adapted to engage an activation tool;
- c. a means for preventing finger access to operate the safety switch;
- and,
- d. an activation tool adapted to engage the tool engaging portion of the safety switch in order to selectively move the safety switch between an on and off position.

A germicidal UV lamp and degermination chamber comprising:
- a. a lamp housing, the housing having a UV light source therein and having at least one aperture allowing the passage of UV light out of the housing
- b. a degermination chamber for receiving objects to be sterilized by UV light from the aperture, a portion of the chamber being adapted to conform to the shape of the housing.
A germicidal UV lamp, comprising:
- a. a housing, the housing having a UV light source therein and at least one aperture allowing the passage of UV light;
- b. a switch formed on the housing, the switch in electrical communication with a power source;
- and,
- c. means selectively moveable in relation to the switch and the housing for preventing finger access to the switch when the means is moved to a first position and allowing finger access to the switch when the means is moved to a second position.

A germicidal UV lamp, comprising:
- a. a housing having a UV light source therein and having at least one aperture allowing the passage of UV light;
- b. electrical terminals located on the housing and in electrical communication with a power source;
- c. a cover over the terminals, the cover preventing finger access to the terminals, the cover having an opening therein adapted to allow passage of an activation tool;
- and
- d. an activation tool, the activation tool formed from an electrically conductive material, the activation tool adapted to pass through the opening in the cover, the activation tool adapted to contact each terminal thereby completing a circuit and allowing current to flow through the terminals and the activation tool.

A germicidal UV lamp, comprising:
- a. a housing having a UV light source therein and at least one aperture allowing the passage of UV light from the housing;
- b. a switch on the housing, the switch in electrical communication with a power source;
- c. a plate having a switch engaging portion, the switch engaging portion engaging the switch, and the plate having a tool engaging portion shaped to engage an activation tool;
- d. a switch cover, the switch cover covering the switch and plate, the switch cover having a opening therein adapted to allow the passage of an activation tool;
- and,
- e. an activation tool adapted to pass through the opening in the switch cover, the activation tool adapted to engage the tool engaging portion of the plate to selectively move the safety switch between an on and off position.
3 more elements
A germicidal UV lamp, comprising:
- a. a housing having a UV light source therein and at least one aperture allowing the passage of UV light;
- b. a switch on the housing, the switch in electrical communication with a power source;
- c. a light shield extending from the housing, the light shield having a window therein aligned with the aperture, the window permitting the transmission of UV light from the housing;
- and,
- d. means for selectively blocking the transmission of UV light from the housing moveably attached to the light shield.
