In Fig. 1 is a bundle of transparent plates according to the invention 1, which are assembled along their faces to form a package or form bundles extending from the front surface or display surface 5 to the rear surface 4 extends. On the front surface 3 and on the parting surfaces 2, a layer 5 can be provided from opaque coating material.

The bundle of panels 1 is traversed by a set of pillars 6 which are made of transparent material, which have prismatic recesses 7 arranged according to the desired visual indications. In other words, the recesses 7 in the plane of each plate 1 form a letter, a number, a symbol or a figure which is to be displayed. Thus, the device of Fig. 1 enables a number of displays to be displayed, the number of which is equal to the number of disks present. In Fig. 1 lo plates are shown. However, it can be stated that their number can be increased to a large extent.

Along one or more sides of the bundle of panels 1 is one movable light source 8 is provided, which is movable in the direction of the arrows and those made of one or more radiating, fluorescent or luminous components consists.

The light source 8 is located in a chamber 9, which may contain

is equipped with an optical collecting lens 10 and serves to to emit a beam of light as narrow as the thickness of the plate 1.

The mode of action is as follows: The beam of light that emanates from the comes from the light sources 8, penetrates through the transparent plate 1 and thereby the columns 6 along the path indicated by the arrows, and is reflected by the prismatic cutouts 7 in the axial direction along the columns and emerges from the front end surfaces 11 in the form of luminous ones Areas or light zones that are white or colored and the desired positions exhibit.

6 and 7 are some number or letter displays as an example shown, while in Fig. 8 a group of illuminated displays can be seen, the are compiled into one word. It is obvious that depending on the number the plates 1 and the columns 6 it is possible to consist of a single bundle or from several bundles joined together to create a sentence, a number or some figure to obtain.

As can be seen from Fig. 1, the end surfaces 11 of the pillars 6 can advantageously be designed with concentric steps in order to be easily recognizable and to get visibility even from a certain point of view, the opposite the normal frontal observation of the display area 7 differs considerably. Of course the surfaces 11 can be lenticular or flat. Also can the front ends of the columns protrude slightly from level 7, as shown in Fig. 1 is shown, or they can cut off flush with this plane or also countersunk be.

In the modification shown in Fig. 2, each plate 1 has one Recess 12 in which a set of light sources 15 or a single light source 14 for each side of the plate is housed. The light sources 15 and 14 are fed by lines 15 which are plugged into a terminal board 16. In In this case, the illuminated displays are obtained by selectively switching them Light sources.

In Fig. 5, the light sources consist of an electro-luminous layer 17, while in Fig. 4 the light of the electroluminescent layer 17 by total reflection a prismatic surface 18 is reflected along the edge of the Plate 1 is created.

In the modification of FIG. 5, the light sources consist of tubular elements 19, which are arranged between the plates 1. The latter will be in this case divided by means of opaque sleeves 20, which have the purpose of eventual Prevent light interference.

Instead of prismatic cutouts 7, it is possible to have rear beam surfaces to use made up of two symmetrical and opposite prismatic surfaces 7t and 7 "(Fig. 9) which receive the light from two opposite directions, or (Fig. 10) the reflection of the light is made by means of a conical surface 7 '' 'reached. For the sake of simplicity, the cross section of the coils 6 in the adjacent Drawings shown in a circle. It is understood, however, that these pillars can also have a rectangular or polygonal cross-section.

In Figs. 11 and 12, the transparent column is designated by the reference number 21 indicated, which has an indefinite length and a circular cross-section. the Device for selective reflection of the light emitted from one or more Light sources 23 originates from a prismatic cutout 22 with a small Consist of depth extending to half the circumference of the column itself, as can be seen from Fig. 12, or can be around the entire circumference, as in Fig. 13, extend.

In Figs. 14 and 15, two prismatic cutouts are 24 and 25 µm half of the circumference provided, which are slightly offset in the axial direction, while in Fig. 16 the means for reflecting back the light emanating from the source 23 comes, consists of two symmetrical depressions 26, which were obtained by that the column 21 was deformed in places without changing the optical To bring about properties of the material from which the named pillars are made.

These devices or impressions can take the form of prismatic cutouts 27 (Fig. 17) or double-prismatic Cutouts 28 (Fig. 19). In FIG. 18 there is a gradual narrowing of the cross section 29 achieved by hot stretching.

In Fig. 20, the column for the transmission of light is in different Sections that are aligned along the optical axis. Everyone Section has a right-angled bent end 30, which is a light source 23 is facing.

In Fig. 21, the end of each section 21 is bent over in a U-shape and has a prismatic end face 31 exposed to the light from the associated source 15 is illuminated.

All of the solutions shown in FIGS. 16 to 21 have transparent ones Columns can have a circular or prismatic cross-section (triangular, square, polygonal etc.). In the event that the pillars are not circular Have cross-section, the modification according to FIG. 22 can be used, which consists of a prism 52, which consists of one piece from the material of the column 21 and forms one or more side surfaces.

It can be stated that for the sake of simplicity of illustration the light sources 23 simply shown schematically in the form of small lamps are; of course, the light source can also be designed in a different manner such as an electrically luminous area.

Another embodiment of the device according to the invention is shown in FIG. In this case the components exist for transmission of light from a series of flexible optical rods or tubes 55 connected to a opaque layer 34 are covered.

The optical rods or tubes 77 are at one end 35 in one opening 36 of a front plate 57 used, which represents the luminous panel, while the other end is 58 in an opening 39 of a plate 40 is inserted is. The openings 59 are in precise proportion to a number of cells 41 arranged, which are divided by partition walls 42 and which the light sources 43 included. In order to quickly and easily check the light sources 43 and to be able to exchange, is the insulating support 44 of these light sources and the Plate 40 as a drawer which can be pulled out by means of a handle 45, as indicated by dashed lines Lines shown in Fig. 23 are formed.

In order to enable this drawer to be pulled out, the conductors 46 of the light sources 45 end in sliding contacts 47, with those with corresponding spring contacts 48, the cooperate with the inner surface of the insulating support 44, which in turn are supported by a fixed and insulating support member 49.

The contacts 48 are connected to current conductors 50, which are not here should be described in detail as they do not form part of the invention.

The mode of operation corresponds to that already described: The Control organs switch the light sources 45 according to the desired sequence one and on the surface of the faceplate 37 are a plurality of luminous Receive points that form the desired display or image representation.

It is also noteworthy in this context that each cell 41 record one or more light sources 43, possibly also in different colors can so that a luminous image in multiple colors is obtained on the front panel 57 will. The embodiment according to FIG. 23 can also be made of transparent by means of rigid columns Material can be achieved that are bent as the figure shows. How to get out 24, instead of the point-like light sources indicated above; 44 small light panels in the cells 51 are arranged. In In this case, the openings 59 of the plate 40 are advantageously conical, so that the entire amount of light emanating from the plates 51 is better captured will.

In Fig. 25, reference numeral 52 indicates a transparent column, which has a number of prismatic cutouts 5 that are partially or entirely extend across this side surface of the column as described above is.

The side surface of the column 52 is transparent with a thin conductive layer 54 coated on top of which another layer of an electro-luminous Material 55 is applied.

In the stop with each prismatic cutout 53 is a conductive one Ring 56 arranged with an insulated wire 57 to a switching circuit connected. The other conductor 58 is electrically connected to layer 54.

If the circuit leading to conductors 57 and 58 is now closed you get a luminous ring that covers the area of the prismatic section 55 surrounds. The light emitted by this ring is reflected by the prism 53 and is now visible at the head of the column.

In Fig. 26 a series of pegs 59 are made of clear material shown, the head ends 60 of which protrude from an overlying plate 61 and the lower parts 62 of which rest on a luminous layer 55. The lower part 62 and the Side surfaces 65 of each peg are covered with a thin transparent conductive layer Layer covered.

The electro-luminous layer 55 rests on an opaque, conductive layer 64 and is pressed elastically against the end 62 of the pin by means of an elastic layer 65 which is arranged between the conductor and a rigid plate 66. The control circuit is connected by means of wires 57 and 58, which in turn are connected to ring 67 which in turn engages the conductive, transparent lateral surface 63 as well as the layer 64 that form the common conductor. When the circuit of the conductors 57 and 58 is closed, a local excitation of the electrically luminous layer 55 is caused at the base of each pin 59. Of course, this selective excitation is accomplished in such a way that the desired luminous display is formed on the faceplate 61 (FIG. 28). Instead of the rings 67, thin sleeves 68 can also advantageously be provided (FIG. 27), which completely or partially surround the side surfaces 65 of the pegs 59 and have an internally mirrored, reflective surface, whereby the light coming from the luminous layer 55 is reflected even better will.

In order to facilitate a physical exchange of the layer 55, can the rigid plate 66 can be designed as can be seen in FIG. 29 and thereby snap-in springs 69 are pressed against the elastic layer 65 with hinges 70. As an alternative solution (Fig. 30), the luminous layer 55 and the conductor 64 can also be in the form of a flexible band are formed, which is pressed elastically against the pin 59 and fed by a coil 71. From time to time the said tape is ticked, the fresh part unwinding from the spool 71 while the used part Part on the collecting coil 72 is wiokelt. In this case the control circuit is connected to the conductor 64 via a sliding contact of known type.

In the modified embodiment according to FIG. 31, the pegs 59 exist made of an opaque, conductive material and are made of transparent sleeves 73 surrounded. When the circuit of conductors 57 and 58 is closed, a local excitation of the electroluminescent layer 55 on the lower parts of the cones 59 generated. In this way, luminous areas are created which can be seen through the sleeves 73 and thereby form the desired luminous display (Fig. 32), Es understands Eich. That the same result also with the pin 59 ff opaque and non-conductive - and with the cuffs 75 - which are transparent and conductive - can be achieved could.

In J? Y. 53, the front plate 61 is provided with openings 74.

The plate 61 rests on a transparent plate 75, which acts as a light distributor works. Under the plate 75 there is a transparent, conductive layer 76, an electro-luminous phosphor layer 55 and a series of individual conductors shown in Aligned with the openings 74 and can be of any shape The local excitation of layer 55 by conductors 57 or 58 creates a plurality of luminous areas which are visible through the openings 74 and which are the desired Make ad.

In the embodiment according to FIGS. E to 36, a housing is indicated by 78, which carries the faceplate 79 through which the front, transparent ends of the pillars 81 htndurehragen. On the other hand, the ropes 81 are prismatic Body 82 provided, attached to the column or with her together from a Piece is made and that of a plate 85 of electro-luminous material is held, which in turn rests on a carrier 84. Any electro-luminous plate is connected to two conductors 85 and 86 by means of, for example, two solder drops: 87 and 88, which are attached to the upper and lower luminous sides of the plate 85.

As can be seen from Fig. 36, the light becomes that from the plate 83 proceeds, reflected by the prismatic body 82 and axially passes through the Column 81 to the front panel 79. This system of light guidance from a horizontal Level (plate 83) to the cylindrical body of the column allows light panels with to produce extremely small front dimensions without relying on point light sources to have to resort to.

The lower conductor 86 of each plate 8) constitutes the common conductor and can thus with the appropriate head of everyone others Components of the panel are connected, while the top conductor 85 from the control circuit is selectively energized so that on the front panel 79 the desired light indication is obtained.

The assembly of the ladder 85, as can be seen from Fig. 57, can be designed like a connection component 89 that is inserted into a base that is connected to the control circuit is connected, can be used.

In the embodiment of Fig. 3b, the transparent pillars are 81 with different lengths and receive the light directly from the electrically luminous ones Plates 85 extending perpendicular to the axis of these same pillars.

In this case, too, a common supply manager is provided, which is connected to the borrowed areas of the plates 83, which are mutually in contact, and in communication with a set of conductors for selective arousal which form a terminal component 89 of FIG. 39. To any To avoid light interference, the vertical columns of the pillars 81 are through non-permeable, insulating panels 90 separated.

40 and 41 show a variant that also includes the Production of light panels with the smallest surface possible. In this case the faceplate 79 has a set of holes 91 and inside the housing 78 are in turn a transparent and insulating protective plate 92, the one Set of transparent conductive zones 93 which correspond to the openings 91 are axially arranged, a layer of an electro-luminous material 94 and finally arranged a conductive floor layer 95. The latter constitutes the common Head out, while the head out with a selective excitation in this case There are wire-shaped elements 96, which are independent with the transparent guide zones 93 are connected and connected to connector 97 for insertion into the control circuit are.

The latter cause the selective excitation of the various areas 95 according to an arrangement that creates the desired display. The opaque one Front plate 79 has the task and purpose of covering the selective conductors 96. The openings 91 serve to provide a precise border of the various light areas which are obtained due to the excitation of the surfaces 93.

In Figs. 42, 43, 45 and 48, reference numeral 98 denotes a sentence Electro-luminous panels that can be selectively excited by means of a conductor loo. These Panels have a series of openings 99 through which the transparent pillars or pegs lol protrude through, which are arranged perpendicular to the plane of these panels are. The front ends of the pegs lol extend through the front plate 102 through which forms the front of the display panel. As from the drawings As can be seen, particularly Figures 42 and 48, the rear end of each post rests on a corresponding, related panel 98 after it has been through the Openings 99 of the various previous panels so that the different tenons have different lengths, depending on the removal, which exists between the relevant board and scoreboard 1o2.

The entire structure is housed in a housing 104 in which a recess 105 is located, which serves to loo the ladder with which the various Tables are fed, take up. These ladder loo end in a build-up of Connections or sockets 103 (see also Fig. 45 and 46), into which the corresponding The plug of the connector 106 is inserted, which thus connects the device with the corresponding Control circuit connects. The way of working is the same as that of the different ones Devices that have already been described: With selective excitation of the various Panels 98 a plurality of luminous dots is generated on the front plate 102, which form the desired display.

In the variant according to Fig. 44, the structure of the panels 98, whose Total depth denoted by B, divided into two compartments C and D, one of which the former has three rows of pegs lol, while the second has two rows. In Fig.

47 are the panels 98 in the same way in two horizontal lines divided. This results in five horizontally arranged panels 98, for each corresponding row of five cones lol. Of course it is possible also to provide a division into vertical rows, whereby, as can be seen in Fig. 47, there are seven vertically arranged panels for each row of seven tenons lol would be.

In Fig. 49, reference numeral 108 indicates a contiguous conductive one Metal layer with a dielectric protective coating 1o9 made of a ceramic material on (flux). Another layer is located on the dielectric layer 109 made of electrically luminous material silo, which is preferably made of ceramic phosphor, that is, from a homogeneous mixture of phosphorus and ceramic powder. On this electro-luminous one Layer 11o is a transparent, conductive layer in that order 111 and a clear protective dielectric layer 112 covering the front panel represented.

By chemical, mechanical, electronic or other means if areas 113 are removed from the metallic layer 108 in full thickness, see above that a plurality of mutually independent plates 114 is obtained (Fig. 50 and 51) that have the desired shape (e.g. round, square, etc.). A wire-shaped conductor, which is selectively excitable, is attached to each plate 114 while the transparent layer 111 is connected to the common conductor 116 which is connected to a corresponding electrical energy source. Will now be the Circuit containing conductor 116 and a certain number of conductors 114, closed, a number of light points or light areas 117 (Fig. 52) behavior that results in the desired display.

The illustration shown in Fig. 53 and 54 shows a Sande tion of the design described above. In this case, the metallic base layer remains 108 whole and the areas which is the entire thickness of the layers Cut 111 and 112 are removed.
