Definitions
- the invention relates to lamps.
- lamps There are different types of lamps, which can be differentiated according to the criteria of functional principle, size, design, power range, etc.
- Concrete designs are, for example, billboards backlit with meandering gas discharge lamps or signal lamps or mirror reflectors with focal points arranged Incandescent lamps for the mentioned aspect of backlighting and lighting, combinations of one or more geometrically large fluorescent lamps with (multiple) reflector systems for office lighting as an example for the aspect of glare-free and low shadow formation, or light tables for working with photo negatives for the aspect of glare-free as well columnar luminaires with upright fluorescent lamps or matt-diffusing glass panes backlit by a large number of incandescent lamps for interior design and decoration.
- Incandescent lamps were also used, for. B. used with reflector systems or systems from a variety of light bulbs.
- a relatively young type of lamp are the fluorescent lamps with a dielectric barrier discharge, which due to their special mode of operation are often designed as flat radiators.
- a discharge volume is formed from plates that are not necessarily flat, in the sense of straight, but flat and largely flat plates, for example made of glass, the electrode structures being produced on one or both glass plates.
- this invention is based on the problem of creating a lamp for application areas with light generation distributed over an area, which functionality or the aesthetic effect adds new possibilities to the state of the art.
- the invention uses the special structure of the flat radiators for dielectrically impeded discharges by the geometric distribution of the discharge electrodes on the flat walls of the discharge volume, ie z. B. on two essentially flat and including the discharge volume together with a frame glass plates, deliberately not homogeneously distributed.
- the invention thus deviates from the general principle prevailing in the prior art in the case of flat lamps or flat panels to be backlit and the like, namely that the aim is to achieve as uniform a surface luminance as possible.
- This alignment of the invention is based on the knowledge that there are many applications in which a local modulation of the surface luminance which is matched to the application can be advantageous by a corresponding inhomogeneous distribution of the electrodes in the surface of the flat radiator.
- Such advantages may lie in the area of better readability of a display or a lettering or signal, in the area of energy saving by better aligning the surface luminance to the local lighting requirements, in decorative effects to be achieved by the invention and the like.
- the electrodes distributed inhomogeneously according to the invention are operated in two or more groups, which can be switched or operated independently of one another.
- the electrodes of each group are connected to their own group-specific cathode or anode connection. This is only possible through the use of dielectrically disabled discharges, which - due to their so-called positive current-voltage characteristics - enable the problem-free parallel connection of several partial discharges or electrode tracks to electrode groups.
- the separately operable groups correspond to specific surface areas of the flat radiator, in particular surface regions of increased luminance, which can then be switched on and off separately from one another.
- the separately operable groups can also be used to power the lamp or to create different surface patterns in order to achieve special optical effects.
- An essential application example for this invention lies in optical displays. These can be analog instruments, as shown in the exemplary embodiment, digital displays, fields with individual symbolized statements which are illuminated by their lighting, such as conventional control lamps, etc.
- a specific surface shape of the display device to be illuminated is specified to which the electrode geometry is matched according to the invention. This creates a higher, the highest or even a surface luminance in the area of the surface shapes to be illuminated. So that can the total amount of light generated and thus the energy consumption are optimized in an application-specific manner, without application-specific shapes or complicated shapes being necessary for the flat radiator as a whole, that is to say its housing geometry or the discharge volume.
- the exemplary embodiment of this invention explained in more detail below relates to a display device in a motor vehicle "dashboard".
- This special case stands for a preferred field of application of the invention, namely display devices in road or rail vehicles, ships or aircraft or motorized means of transport in general .
- the ergonomic requirements for display devices and fittings are particularly high in this area.
- a special case for the area of display devices from a geometrical point of view are the analog displays, in which, as illustrated in the exemplary embodiment, the following forms of backlighting occur primarily due to an adapted electrode geometry: circles, circle segments, circular rings and circular ring segments.
- Such shapes can be backlit with the conventional technology practically only defined by the use of diaphragms or masks, so that the invention can offer significant advantages in terms of the simplicity of the technical structure and the energy consumption. This applies in particular to circular rings or circular ring segments and other tall shapes or shapes curved around an inner region.
- the invention is not to be understood as being restricted to the area of signal lamps or display devices.
- interior lights are mentioned.
- the flat radiator technology with dielectrically impeded discharge also appears to be interesting here, particularly because of the possibility of constructing large-area flat lamps for indoor use with very low surface luminance values compared to incandescent lamps.
- a particular decorative or aesthetic effect can be achieved in many respects by the local modulation of the surface luminance according to the invention.
- a flat spotlight mounted flat on the wall of the room can be given a particularly appealing design through an aesthetically appealing structuring of the luminance distribution. This is particularly true in contrast to the completely homogeneous and closed outer shape of such a luminaire that can be achieved through the uniform discharge volume.
- the group division of the electrodes already described above for separately switchable operation there are various options for using the group division of the electrodes already described above for separately switchable operation.
- the invention will now be illustrated with the aid of a concrete exemplary embodiment, which is shown schematically in the figure.
- the figure shows a plan view of a flat radiator for a motor vehicle "dashboard" for backlighting a combination instrument for displaying the speed, the engine speed, the cooling water temperature and the tank content.
- a discharge volume labeled 1 which is enclosed by two glass plates lying flat in the plane of the drawing and a seal running along the drawn-in edge. In the lower area of the figure, the glass plates protrude beyond the discharge volume 1 with an attachment labeled 3.
- the pump nozzle used for evacuation and filling (in the closed state) is shown on the right-hand edge.
- Summarized with 2 are the electrodes printed on one of the plates, the cathodes and anodes running alternately, but not differentiated in the figure. With most of their length, the electrodes 2 lie in the discharge volume 1 and are at their outside of the Discharge volume 1 part located in the area of approach 3 connected to the supply circuit and automotive electrics.
- the electrodes 2 are in three spatially separate groups 2a, 2b and 2c, each of which corresponds to specific display units or contents.
- the left group 2a corresponds to an analog instrument for speed display and, apart from its straight section leading to the approach 3, guides the circular ring segment of this analog instrument.
- group 2b corresponding to an engine tachometer.
- two instruments are combined, namely a tank level indicator and a cooling water thermometer.
- the electrodes 2 are printed on one of the two glass plates by the screen printing method. They are coated with a glass barrier as a dielectric. The distance between the two glass plates is about 7 mm, wherein they are connected as a seal via a glass frame forming the outer edge of the discharge volume 1 with glass solder.
- the invention is distinguished by a technically simple and rationally producible structure and a distribution of the surface luminance which is precisely adapted to the design of the display device. This improves energy efficiency and ergonomics.
- flat radiators with dielectrically impeded discharge are also particularly advantageous because they have a high switching stability and are not sensitive to vibrations and their service life is basically limited only by the stability of the phosphors used (“maintenance”).
- the geometry of the flat radiators can also be advantageous, as, as is clear in this exemplary embodiment, the shape and size can be adapted particularly well to the place of use or installation.
- the present invention nevertheless allows the use of simple flat radiator housing shapes, in the present example the outer shape of the discharge volume 1 including the extension 3 instead of the complicated circular ring segments with connecting pieces.
- the flatness is also advantageous in the limited space in a dashboard, cockpit, etc. The same applies to the low weight.
