Abstract
An excimer lamp includes a plurality of arc tubes and an electrode pair. The electrode pair comprises a plurality of elongated electrode plates extending along a tube axis direction of the plurality of arc tubes. Each electrode plate comprises a polarity opposite that of an adjacent electrode plate (i.e., alternating polarities). The plurality of arc tubes and the plurality of electrode plates are disposed in an alternating side-by-side orientation such that an arc tube of the plurality of arc tubes is disposed between adjacent electrode plates of the plurality of electrode plates.
Claims19
An excimer lamp comprising:
- a plurality of arc tubes;
- and
- an electrode pair comprising a first electrode and a second electrode,
- wherein the first electrode comprises a first end portion disposed at a first end of the plurality of arc tubes, a first extension extending from the first end portion at a first extension point, and a second extension extending from the first end portion at a second extension point, wherein the first end portion of the first electrode extends between and terminates at the first extension point and the second extension point, and wherein the second electrode comprises a second end portion disposed at a second end of the plurality of arc tubes, and a third extension extending from the second end portion, the third extension disposed between the first extension and the second extension.
A sanitization apparatus comprising:
- a power supply comprising a first positive lead, a second positive lead, and a negative lead;
- and
- an excimer lamp comprising a plurality of arc tubes and an electrode pair comprising a first electrode and a second electrode;
- wherein the negative lead is coupled to the first electrode disposed on a first end of the plurality of arc tubes at a location substantially midway between a first end of the first electrode and a second end of the first electrode;
- and
- the first positive lead is coupled to a first end of the second electrode disposed on the first end of the plurality of arc tubes;
- and
- the second positive lead is coupled to a second end of the second electrode disposed on the first end of the plurality of arc tubes.
An excimer lamp comprising:
- a plurality of arc tubes;
- a plurality of electrode plates extending along a tube axis direction of the plurality of arc tubes, wherein each electrode plate of the plurality of electrode plates comprises a polarity opposite that of an adjacent electrode plate, and wherein the plurality of arc tubes and the plurality of electrode plates are disposed in an alternating side-by-side orientation such that an arc tube of the plurality of arc tubes is disposed between adjacent electrode plates of the plurality of electrode plates;
- a first end portion disposed at a first end of the plurality of arc tubes connecting alternating electrode plates of a first polarity;
- and
- a second end portion disposed at a second end of the plurality of arc tubes connecting alternating electrode plates of a second polarity, wherein the first end portion has a width that is less than a total width of the plurality of arc tubes.
