Abstract
An excimer lamp comprises an enclosure having one or more windows, and electrodes distanced from the one or more windows such that UV light generated inside the enclosure in a region near the electrodes travels a predetermined minimum distance before exiting the enclosure. The excimer lamp further comprises a heat sink having one or more first surfaces facing an environment outside the enclosure and one or more second surfaces facing the electrodes or the region near the electrodes. The heat sink is configured to receive heat from the electrodes and/or the region near the electrodes through the second surfaces and to conduct the heat to the environment outside the enclosure through the first surfaces. The one or more first surfaces has an area that is at least twice an area of the one or more second surfaces.
Claims20
An excimer lamp, comprising:
- an enclosure having one or more windows that allow UV light to pass through and exit the excimer lamp, the enclosure forming an enclosure of, or enclosing, a UV bulb, wherein, in a cross section of the excimer lamp perpendicular to a longitudinal direction of the excimer lamp, the UV bulb has a circular circumference;
- electrodes each extending along the longitudinal direction of the excimer lamp and distanced from the one or more windows such that UV light generated in one or more UV generating regions near the electrodes travels a predetermined minimum distance of at least 2 cm before exiting the enclosure through the one or more windows, the electrodes including first and second electrodes of opposite polarities, wherein, in the cross section of the excimer lamp, the first electrode abuts a first arc of the circular circumference and the second electrode abuts a second arc of the circular circumference, the second arc being distinct and apart from the first arc;
- and
- a heat sink extending along the longitudinal direction of the excimer lamp and having first surfaces facing an environment outside the enclosure and second surfaces extending along the longitudinal direction of the excimer lamp, each of the second surfaces facing a respective one of the electrodes and/or a respective one of the one or more UV generating regions, and each of the electrodes abuts at least one of the second surfaces, wherein the heat sink is configured to receive heat from the electrodes and/or the one or more UV generating regions through the second surfaces and to conduct the heat to the environment outside the enclosure through the first surfaces, the first surfaces having a total area that is at least twice a total area of the second surfaces.
