Embodiment Construction

[0098] Figure 1 shows a coplanar discharge planar UV lamp 1 comprising a first and a second glass plate 2,3 each having an outer surface 21,31 and an inner surface 22,32. The lamp 1 emits UV radiation only via its surface 31 (symbolized by arrow F). This also makes it possible to protect other sides, which may be susceptible, from UV radiation.

[0099] The area of ​​each glass plate 2,3 is for example about 1m 2 , or even larger, and its thickness is 3mm.

[0100] The plurality of electrodes 41, 51 are coupled in pairs. They are in the form of strips deposited directly on the outer surface 21, eg screen printed with silver ink, or they may be adhesively bonded copper strips.

[0101] The electrodes can also be configured as strips formed from arrays of conductive filaments.

[0102] At least in the region of the electrodes, the outer surface 21 is itself filled with an electrically insulating and protective plastic film 14 . In this embodiment, the dielectric 14 may be t...

Abstract

The invention concerns a flat lamp (1) transmitting an ultraviolet radiation (UV), comprising: first and second flat or substantially flat glass elements (2, 3) maintained substantially mutually parallel and delimiting an internal space filled with gas (10) capable of emitting said UV radiation or of exciting a phosphorous material optionally present and emitting said UV radiation, said phosphorous material being then arranged on one surface of the first and / or of the second glass element, the first and / or second glass element (2, 3) being made of a material transmitting said UV radiation; a plurality of pairs of electrodes (41, 51) capable of being at different potentials and of being powered by an alternating voltage, said pairs being associated with the first glass element and arranged outside the internal space, the electrodes being in the form of strips and / or wires in the first glass element or in another dielectric element associated with the first glass element. The invention also concerns the uses of said lamp.

Description

technical field [0001] The present invention relates to the field of planar ultraviolet (UV) lamps, and in particular to coplanar discharge planar UV lamps and applications of the lamps. Background technique [0002] Conventional UV lamps are formed from UV fluorescent tubes filled with mercury and placed side by side to form an emitting surface. These tubes have a limited lifetime. Furthermore, it is difficult to obtain uniform UV radiation emitted over large areas. Finally, the lamp is heavy and large. [0003] Document US5006758 proposes a planar UV tanning lamp consisting of two UVA-transmissive glass plates separated by a short distance and hermetically sealed to contain the gas at reduced pressure. The electrical discharge generates UV radiation, which excites the fluorescent coating emitting in UVA. [0004] One of the glass panes bears on its inner surface a fluorescent coating, while the other glass pane bears on its inner surface a series of electrodes or condu...
