Definitions

• the present invention is related to a marking plate device intended to receive, at optionally selected positions, light emitting marking means with two electrodes to be stuck into a plate, said device further comprising at least two electrically conducting layers which are isolated from and parallel to each other, and means, preferably an isolating layer, being provided to break the electrical connection between the conducting layer adjacent said marking means and the electrode which is to be conductively engaged with a following conducting layer at the point where this electrode extends through the layer adjacent said diode.
• US-PS 697,856 is related to a device comprising a lamp each pole of which being connected to a conducting layer.
• This complicated device is intended to be used as a light source for lightning purposes and is further not usable today as it is applicable on a heavy current curcuit.
• the device must have been found unusable, e.g. from a security point of view, not long after the patent was granted in 1902. Hence, it cannot constitute an encitement for the appliance of the device according to the invention.
• An object of the present invention is to provide a marking plate device, by means of which it is possible to obtain a marking emitting light in a quick and efficience way anywhere over said marking plate by pushing said marking means into said plate.
• said marking means each comprises a light emitting diode which when applied on said plate emits light by conductively engaging each electrode with the corresponding conducting layer.
• Fig. 1 shows in cross-section a first embodiment of a marking plate device according to the invention.
• Fig, 2 shows in cross-section a second embodiment of a marking plate device according to the invention.
• Fig. 5 shows a cross-section along the lines III-III in Fig. 2.
• a marking plate device 1 comprising an upper iayer 2, which e.g. consists of a map, an upper, electrically conducting layer 3, an intermediate situated, isolating layer 4, and a lower, electrically conducting layer 5.
• a light emitting diode 6 is so placed on said plate 1, that the light emitting body 6 thereof emits light.
• the light emitting diode 6 has two electrodes 7 and 8, one electrode 7 of which has an isolated part 9, and the other electrode 8 is shorter than the partly isolated electrode 7 and approximately as long as the isolated part 9.
• Each conducting layer 3 and 5 has been connected to a pole of an electric source, permitting each electrode, when the light emitting diode 6 is placed upon said plate so that the electrodes 7 and 8 are stuck into the same, to conductively engage with the corresponding layer of said plate so that the light emitting diode 6 Is turned on and emits light.
• the overlying, electrically conducting layers 3 and 5 consist of e.g. tin foil, close-meshed nets, or other electrically conducting materials.
• a second embodiment of a marking plate device according to the invention is shown, in which similar parts have been designated with the same reference numerals as in Fig. 1.
• the device according to this embodiment comprises two coaxially arranged electrodes 10 and 11, which each conductively engages the corresponding electrically conducting layer 3 and 5, respectively.
• Fig. 3 shows that an isolating part or layer 12 is provided between the electrodes 10 and 11. Concerning the function of this embodiment reference is made to the function of the embodiment according to Fig. 1.
• the electrodes of the light emitting diodes consist of plates which at the bottom are provided with an edge or the like and which are arranged side by side with intermediate isolating material.
• a possible solution is to manufacture a socket with electrodes, said socket being provided with a layer of isolating material on the electrode which is to be conductively engaged with the conducting layer adjacent said socket.
• This socket is also provided with recesses to receive and anchor the electrode of a light emitting diode.
• the device according to the invention is thus used preferably to mark places on a map so that simultaneously the marking means emits light. This has as has been described above been possible to perform in a restricted extent among other things on such maps which have firmly secured lamps but it has not been possible before to optionally place a great number of light emitting marking means on a map.
• breaking off of the electrical connection between an electrode and said adjacent layer is not restricted to be accomplished by providing the electrode with an isolating layer. This can be accomplished in other ways, e.g. by means of separating fingers.
