Definitions

  • the invention relates to lamps. There are different types of Lamps that are based on the criteria of functional principle, size, design, Differentiate performance range etc.
  • Lamp types for certain applications lie in the flatness of the Light generation and the uniformity of the flat light generation. At some use cases are about giving some examples, to illuminate an area of a certain extent, a certain one Distribute light output over a certain area to reduce glare a lighting solution for the sake of reducing shadow formation to find with light distribution distributed as flat as possible for decorative or design reasons, a lamp is particularly large perform and the like.
  • Incandescent lamps for the aspect of flat backlighting mentioned and lighting
  • combinations of one or more geometric large fluorescent lamps with (multiple) reflector systems for office lighting as an example of the aspect of non-glare and low shadow formation or light tables for working with photo negatives for the point of view Glare-free and columnar lights with upright Fluorescent lamps or backlit by a large number of incandescent lamps, matt-diffusing glass panes for interior design and decoration.
  • Incandescent lamps were also used, for. B. with reflector systems or systems from a variety of incandescent lamps.
  • a relatively young type of lamp are the fluorescent lamps with a dielectric disabled discharge due to their special functioning are often designed as flat radiators. This is a discharge volume formed from not necessarily planes in the sense of straight, but flat and largely flat plates, such as glass, with the electrode structures are made on one or both glass plates.
  • This invention is based on the prior art illustrated Technology based on the problem of having a lamp for application areas to create an area of distributed light generation that is technical Functionality or the aesthetic effect state of the art adds new opportunities.
  • the invention uses the special structure of the flat radiators for dielectrically impeded discharges by changing the geometric Distribution of the discharge electrodes on the flat walls of the discharge volume, so z. B. on two substantially flat and the discharge volume together with a glass plate enclosing a frame, deliberately not distributed homogeneously.
  • the invention differs from that in State of the art for flat lamps or flat lamps to be backlit Tables and the like in the generally prevailing principle that namely a uniform luminance is sought.
  • Electrodes in two or more distributed inhomogeneously Groups operated, which can be switched or operated independently of one another are.
  • the electrodes of each group are on their own Group-specific cathode or anode connection connected.
  • the separately operable groups each have specific areas of the Let the flat radiator correspond, in particular surface areas increased Luminance, which are then switched on and off separately can. You can also use the separately operated groups Use the power rating of the lamp or to create different ones Surface pattern to achieve special optical effects.
  • An essential application example for this invention is optical Show. These can be analog instruments, as in the Embodiment shown to digital displays to fields with individual, through their glow certain symbolized statements of validity bringing display fields, such as with conventional indicator lamps, etc.
  • there is a specific surface shape to be illuminated of the display device given the electrode geometry according to the invention is coordinated. This is in the area of the surface shapes to be illuminated a higher, the highest or even a surface luminance. This allows the total amount of light generated and thus the energy consumption can be optimized for specific applications without using the flat radiator overall, i.e. its housing geometry or the discharge volume application-specific shapes or complicated shapes necessary become.
  • 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 area 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 or fittings are particularly high in this area.
  • a special case for the area of display devices in geometric terms are the analog displays in those, as in the embodiment illustrates, especially the following forms of backlighting by a Adapted electrode geometry occur: circles, circle segments, circular rings and circular ring segments.
  • Such forms are with the conventional technique practically only defined by the use of screens or masks backlight, so that the invention here in terms of simplicity of technical structure and energy consumption offer significant advantages can. This applies in particular to circular rings or circular ring segments and others tall or curved shapes.
  • the invention is not in the field of signal lamps or to understand display devices to a limited extent.
  • the invention is not only technical and ergonomic Indoor lights offer advantages.
  • the local according to the invention Modulation of the surface luminance is special in many ways decorative or aesthetic effect can be achieved. You can z. B. imagine graphically designed screens with appropriately adapted Flat spotlights to deposit, so that certain elements in the screen can be specifically highlighted by their brightness, for example in figurative Representations for the children's room.
  • 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.
  • the outer edge of a discharge volume denoted by 1 is initially shown, that of two lying flat in the drawing plane Glass plates and one running along the drawn edge Seal is included.
  • the protrude in the lower part of the figure Glass plates with an approach labeled 3 over the discharge volume 1 beyond.
  • On the right is the one for evacuation and filling used pump nozzle (in the closed state).
  • Summary 2 denotes the electrodes printed on one of the plates, with cathodes and anodes alternately running in the Figure are not differentiated, however. With most of its length are the electrodes 2 in the discharge volume 1 and are outside of it of the discharge volume 1 located in the area of the approach 3 connected to the supply circuit and automotive electrics.
  • the electrodes 2 are in three spatially separate groups 2a, 2b and 2c before, each corresponding to certain display units or content.
  • the left group 2a corresponds to an analog instrument for speed display and leads from their leading to Approach 3 straight section apart, the circular ring segment of this analog instrument after.
  • group 2b two instruments are combined, namely a tank level indicator and a cooling water thermometer.
  • the electrodes 2 are screen-printed on one of the two Printed glass plates. They are with a glass barrier as a dielectric coated. The distance between the two glass plates is about 7 mm, being a seal over the outer edge of the discharge volume 1 forming glass frame are connected with glass solder. That so tight included discharge volume contains a Xe fill as discharge fill at about 100 mbar.
  • 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 insensitive to vibrations and their service life is basically only due to the stability of the phosphors used ( Maintenance ”) are limited.
  • the geometry of the Flat radiators which, as is clear in this exemplary embodiment, can be adapted particularly well in shape and size to the place of use or installation, although 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 approach 3 instead of the complicated circular ring segments with connecting pieces, and the flatness is also advantageous in the limited space in a dashboard, cockpit, etc. The same applies to the low weight.
