The invention relates to a line duct for sealing a wall opening through which a line passes, comprising an elastomer body with a series of layers surrounding the line. The elastomer body and the series of layers are made up here of a number of respective one-piece elastomer body parts () with shells (), according to the invention there being arranged between the shells () of an elastomer body part () at least two shells () of other elastomer body parts ().

Line duct with a series of layers

A conduit duct for sealing at least one conduit includes an elastomer body for sealingly contacting the conduit. The elastomer body comprises at least two elastomer parts, wherein each of the elastomer parts includes a plurality of hollow sleeves. In an assembled condition of the elastomer body parts, the hollow sleeves of one of the body parts are arranged with the hollow sleeves of the other one of the body parts to form a sequence of layers surrounding the conduit. A tensioning device positioned on the elastomer body compresses the elastomer body to thereby sealingly press the body onto the conduit.

Conduit duct with sequence of layers

A process for producing a discharge vessel of a flat gas discharge lamp, in which the discharge vessel has a base plate (), a frame () and a cover plate (), as well as at least one spacer () between base plate () and cover plate (). At least between one of the plates () and the frame (), at least one space () is initially kept open as a filling opening. By partial fusion of at least a part () of the frame, which may also comprise a layer () of soldering glass and local elevations (), the filling opening () is eliminated after the filling operation. The distance between the vessel plates () is defined by the spacers (), which remain hard even during the joining operation.

Method for producing a gas discharge lamp

A discharge lamp, suitable for operation by means of dielectrically impeded discharge, having a discharge vessel with two at least partially parallel vessel walls (), and at least one spacer () made from optically transparent insulating material. The or each spacer () is in contact with the two vessel walls () via bearing surfaces. The or each spacer has an optically diffuse surface () at least in the region of one bearing surface.

The invention relates to an improved color display with temporary sequential primary color mixing, in the case of which a discharge lamp for dielectrically impeded discharges is used for backlighting.

Color display having sequential primary color generation

A flat lighting device ( ) has two mutually opposite, at least partially transparent view surfaces in such a way that light from a light source, for example daylight or ambient light, backlighting the lighting device can pass through the transparent part ( ) of the view surfaces. Moreover, the lighting device has at least one integrated light source, the, or each, light source being arranged in such a way that during operation a corresponding luminous area ( ) inside at least one of the two view surfaces is formed by the, or each, light source.

Flat illumination device

The invention relates to a flat discharge lamp ( ), comprising two substantially parallel plates ( ) and two support areas serving to support both plates against each other. Each support area consists of a component having a high-viscosity ( ) and a low viscosity ( ) at assembling temperature. Before assembling the discharge vessel, the support areas are larger than final distance envisaged between both plates. The low viscosity component ( ) compensates for possible local deviations in the distance between both plates when the discharge vessel are assembled.

Flat discharge lamp and method for the production thereof

A flat illumination device ( ), includes a base plate and a front plate which are connected to form an at least partially transparent vessel which, in its interior, has an ionizable fill. In a partial region of the vessel, at least one of the two plates is at least in part provided with a mirror surface. An unmirrored partial region ( ) of the vessel is designed to realize an illumination function.

In a novel method in the field of the production of discharge vessels, in particular for silent flat radiators, an exhaust tube for evacuating and filling is inserted into an opening in the discharge vessel, it being possible in a simple way by means of an adapter to achieve optimum fitting and sealing between a square inner cross section of the opening and a round outer cross section of the exhaust tube

Method for inserting a pumping rod in a discharge chamber

A gas discharge lamp having a discharge vessel, for example composed of a base plate, front plate ( ) and frame ( ), has at least one closure element ( ) which closes a discharge vessel opening in a gas-tight fashion by virtue of the fact that the closure element ( ) was inserted into the discharge vessel opening and subsequently fused. The closure element ( ) consists of a material which is low-melting by comparison with the remainder of the discharge vessel, for example sintered glass. It is possible to dispense with an additional connecting means between the closure element ( ) and the adjacent wall of the discharge vessel ( ).

Gas discharge lamp and method for the production thereof

A discharge lamp, suitable for operating by means of a dielectrically impeded discharge, and having metal electrodes arranged on the wall of the discharge vessel has at least one dielectric impeding layer which covers at least a portion of the electrodes. According to the invention, the electrodes are additionally covered directly with a barrier layer, in particular made from sintered glass ceramic, that is to say the barrier layer is, if appropriate, respectively arranged between the electrode and the dielectric impeding layer. The result of this is to prevent metal ions from diffusing out of the electrodes into the dielectric impeding layer and undesirably influencing the properties thereof. Moreover, it is possible in this way to prevent the electrode tracks from evaporating or being sputtered away during operation of the lamp.

Discharge lamp with dielectrically inhibited electrodes

A discharge lamp, suitable for operation by means of dielectrically impeded discharge, having electrodes arranged on the wall of the discharge vessel, has at least one dielectric layer which covers at least a part of the electrodes and, optionally, the discharge vessel wall as well. A phosphor and/or reflective layer is arranged on the at least one dielectric layer. According to the invention, at least the dielectric layer arranged directly underneath the phosphor or reflective layer consists of a glass solder whose viscosity variation as a function of temperature is irreversible, in particular of a sintered glass ceramic. This prevents this layer from re-melting during the fabrication process and thereby tearing the overlying porous reflective and/or phosphor layers.

Discharge lamp with dielectrically impeded electrodes

A fluorescent lamp, in particular for the backlighting of liquid crystal display screens, having a discharge vessel with a gas filling, the discharge vessel having a fluorescent layer and an electrode structure for a dielectric impeded discharge, the electrode structure fixing a geometric distribution of partial discharges and the fluorescent layer having a thickness variation in accordance to the geometrical distribution of the partial discharges.
