Description

The present invention relates to an arrangement in a marking plate for receiving light-emitting means for receiving at arbitrarily selected locations, provided with two electrodes for insertion into a plate comprising at least two mutually isolated, superimposed an electrically conductive layer having a means, primarily an insulator, for disconnecting the electrical connection between the layer adjacent to the indicating member and the electrode for conductive adhesion with the next layer at the point where said electrode is passed through said layer adjacent to the diode.

when connecting electrical conductors consisting of a plurality of conductors, the insulating plastic is peeled off the ends of the conductors, and then these ends are pressed or screwed into a switch box or the like to provide a conductive connection between the conductors. In this method, it is time consuming, and the switch box often comprises many parts that reduce the overall reliability of the unit.

U.S. Patent No. 697,856 relates to a device comprising a lamp, the poles of which are each connected to their own conductive layer. This complex device is intended to be used as a light source for lighting purposes and, in addition, is not usable today because it is suitable for a high current circuit. The device must have proved to be invalid, inter alia from a safety point of view, shortly after the patent was granted in 1902. It cannot therefore constitute an indication of the application of the device according to the invention.

U.S. Pat. No. 11,970, including U.S. Pat. No. 4,990, discloses a device for providing conductive connections to superimposed conductive layers. This device has pins υη provided with insulation from an area located in the plane of the 2 714 4 4 layer with which no conductive connection is intended. This device is also not intended to be used with a marking plate,

When making markings on maps or the like, button pins of different colors are often used to mark different places, such as places of manufacture and sale. There are maps in which such pin pins have been replaced by colored lamps fixed to the maps. In contrast, it is not known to press the marking member mie-10 violently on a map or some other similar flat plate and that the marking means then emit light.

The object of the present invention is to provide a marking plate of the type described in the preamble, by means of which it is possible to obtain a light emitting mark on any marking plate in a fast and efficient manner by pressing in said marking means.

The object is achieved in that each of said indicating means comprises a orbital diode which, when mounted on the plate 20, emits light, since said electrodes each come into conductive contact with their own conductive layer.

Preferred embodiments of the invention are characterized by the subclaims.

25 The use of light emitting diodes, which is completely new in this range, gives essentially the same luminous intensity over the whole map at the same voltage, since the light emitting diodes are designed to achieve Iran ignition voltage, the light emitting diodes shine mainly at constant intensity regardless of voltage-50 voltage variations.

The invention will now be described in more detail with reference to the accompanying drawing, which shows preferred embodiments. Figure 1 is a longitudinal section of a first embodiment of a marking plate arrangement according to the invention. Fig. 2 35 is a longitudinal section of a second embodiment of a marking plate arrangement according to the invention. Fig. 3 is a cross-section along the line III-III in Fig. 2.

Figure 1 shows a longitudinal section of a marking plate 3 71444 1 consisting of an upper layer 2, which may be a map, an upper electrically conductive layer 3, an intermediate insulating layer 4 and a lower electrically conductive layer 5. The light emitting diode 6 is arranged on the plate 1 so that its fluorescent body 6 emits light. The light emitting diode 6 has two electrodes 7 and 8, one of which has an insulating part 9 and the electrode 8 is shorter than the electrode 7 and is approximately the same length as the insulation 9. The conductive layers 3 and 5 are each electrically connected. to the pole of the power supply, which causes that when the light emitting diodes 6 are mounted on the plate by inserting the electrodes 7 and 8 into it, these electrodes each conductively adhere to their own conductive layer in the plate so that the light emitting diode is connected and emits light.

The superimposed electrically conductive layers 5 and 5 consist, for example, of a stanniol film, a dense network or some other electrically conductive material.

Figures 2 and 3 show another embodiment of a marking plate arrangement according to the invention, in which the parts corresponding to the parts of Figure 1 are given the same reference elements. As can be seen from Figure 2, this embodiment comprises two coaxially arranged electrodes 10 25 and 11, each of which conductively adheres to its own electrically conductive layers 3 and 5.

Figure 3 shows that the insulation 12 is arranged between the electrodes 10 and 11. With respect to the operation of this embodiment, reference is made to the Iru-30 embodiment of Fig. 1.

Another embodiment, not shown in the drawing, consists in that the electrodes of the light-emitting diode consist of plates with a tip or blade at the bottom, which are arranged side by side with intermediate insulation.

In the further development of the invention, it has proved that one possible solution is to make a plug with electrodes provided with an insulator which is not on top of the second electrode with respect to the raised layer, the lana plug is provided with sockets for receiving and attaching the LED electrodes.

The arrangement according to the invention is thus used to mark the locations on the map at the front entrance so that the signs at the same time emit light. As described above, this has been possible to a limited extent, inter alia, on maps with fixed light points, but in the past it has not been possible to place an arbitrarily large number of light emitting signs on the map.

It is, of course, clear that the disconnection of the electrical connection between the electrode and the upper layer does not have to take place with an insulating layer in the electrode, but this can also take place in other ways, for example with fingers separating the upper layer from the electrode.

The invention may be further modified within the scope of the following claims.
