Description

The invention relates to a device with dynamic LED display for outdoor or indoor use with a housing with single-sided or double-sided LED display and one in it arranged control computer and a power supply, in particular for the public transport, being a circulating narrow frame of the case of two transparent panes is covered and related to control semiconductors LED modules are mounted on a mounting plate.

In this case, an installation location is under the "outdoor area" Understand, basically exposed to the outside atmosphere and Under the "interior" such a location is understood, the the influence of the external atmosphere with its arrangement in Interiors of buildings or vehicles is withdrawn.

A known device of this kind according to the Although DE 102 07 264 C1 has the expectations placed in it full fulfilled, however, has in a repair as disadvantageous proved that then one of the two glued waterproof Transparent windows can not be removed non-destructively, taking also the LED display facing this disc affected is pulled. Because in this device is on a encircling, closed frame as a housing part on one or on both sides of the frame each a full-surface LED display panel as further housing part by means of a double-sided adhesive, thin, Strominsolierenden and thermally conductive transparent film glued waterproof. This glue has turned out to be that way Materialverbindend exposed that a non-destructive opening of the enclosure by removing an LED display panel is possible. And finally, this device has as disadvantageous exposed the considerable storage costs, because always only complete devices could be stored in stock, as alone on the LED display panels by means of double-sided adhesive Transparency glued on transparent panels with a Setting time of the glue are subject to two days and only ever put finished, no longer changeable devices in stock could become.

From DE 298 19 742 U 1 is a further device of discloses at the beginning of the type mentioned, in which in an im Cross-section of trapezoidal housing components, such as light-emitting diodes, Circuit boards, power sources, power and more mechanical and electrical components are arranged, as commonly used for traffic information displays / displays be used. The housing is on both sides of a closed transparent cover. These Covering device, which in a known, actual Embodiment of this device by means of the upper edge of the housing mounted hinged joints designed hinged, consists of an outer surface and an inner display surface. The outer surface is covered with a color film of molten glass Mistake. The inner display surface consists of a layer or a film of transparent material made of melted glass. The inner display area is of a circumferential, opaque frame framed as passepartout. Thereby inevitably reduces the display area of the Covering device to the light-emitting diodes arranged in the housing. The case is extremely bulky. In a repair must Cover device folded up or otherwise removed to for repair purposes access to the interior of the housing to accomplish. In particular, the renewed proves to be critical Sealing of the cover on the housing opposite Rainfall. After a replacement of the cover As a closure of the housing must by no means a tightness of the Be given housing.

Starting from this closest state of the art, the invention has the object, a device of to create the aforementioned type, while maintaining a small depth and an effective waterproofness nevertheless a non-destructive access to the interior, For example, for repair purposes, as guaranteed as a secure static mounting of the LED modules as well as a considerable reduced storage costs.

a) die Vorrichtung weist ein Außengehäuse und ein Innengehäuse auf,

b) das Außengehäuse besteht aus einem schmalen, an drei Seiten geschlossenen Rahmen, auf dessen vierter Rahmenseite das Innengehäuse lösbar aufgeständert und befestigt ist,

c) die beiden transparenten Scheiben des Außengehäuses sind über eine Dichtung mit den drei Seiten des Rahmens verbunden, und

d) das Innengehäuse ist von den mit den LED-Modulen bestückten Halterungsplatten gebildet, die lösbar mit der vierten Rahmenseite des Außengehäuses verbunden und diese nach Einschub des Innengehäuses in das Außengehäuse mit den beiden angrenzenden Rahmenenden des Außengehäuses über ein lösbares Dichtungsmittel verschraubt ist.

This object is achieved in connection with the generic term mentioned above by the following features,

a) the device has an outer housing and an inner housing,

b) the outer housing consists of a narrow, closed on three sides frame, on the fourth frame side, the inner housing is releasably raised and fixed,

c) the two transparent panes of the outer housing are connected via a seal with the three sides of the frame, and

d) the inner housing is formed by the equipped with the LED modules support plates, which is detachably connected to the fourth frame side of the outer housing and this is screwed by inserting the inner housing into the outer housing with the two adjacent frame ends of the outer housing via a releasable sealant.

This is in departure from the completely closed Housing according to DE 102 07 264 C1, in which the LED modules glued over a transparent film with a transparent panel are now dissolved this one-piece in a two-part housing, in which the inner housing on the fourth frame side - that is usually the lower side of the outer housing - is elevated and is inserted as a plug-in unit in the outer housing.

Between the compact mounting plates of the LED modules formed inner housing become the control computer and the power supply arranged.

In addition, with this inventive concept now the previous storage costs are drastically reduced by the fact that only unpopulated outer housing without elevated inner housing can be stored and as needed and customer request so to speak put together the inner casing at lightning speed, elevated and completed the entire device can.

According to an advantageous embodiment of the invention that is Inner housing with two LED display panels in the form of the Mounting plates for each of the two transparent panes of the Exterior housing provided on at least their four Corner areas have a coupling pin with which they to its two opposite sides detachable in one as Spacer trained coupling element are inserted. This allows the compact mounting plates of the Inner housing by means of a simple plug-in form a cube designed as a coupling element with each other be coupled. For larger disk units a To prevent deflection in the interior, then this or similar coupling elements in the interior between the arranged two disk units.

In the space between the two mounting plates is advantageous to one each with the support plates and / or with the Frame sides of the outer housing connected support plate once the power supply and once the control computer arranged.

After a particularly advantageous development of Invention, the LED modules and their control semiconductors means a thermally conductive, double-sided adhesive film with a board mounted on heat sinks, which are embedded in the latter and attached to it threaded bolt and coupling tabs with the same Groove bolted together to form a compact mounting plate are.

This will add an extra bracket plate, such as For example, in the subject of DE 298 19 742 U1, thereby dispensable that the heat sink of the LED modules themselves with the Connecting straps converted into a mounting frame be by in this heat sink threaded bolts are embedded, the with their screw surfaces from the surface of the heat sink protrude and there by joints equal joints are bolted together to form a compact mounting plate. This can be done by any stringing together of the LED modules these on their heat sink side to relatively long and wide LED scoreboards are bolted together. This special Training also has the advantage that with the power supply and the control computer connected carrier plates also off Metal are made and made with an aluminum alloy existing heat sinks for heat dissipation of heat from both the LED modules and those of the power supply and Control computer can be used and to ensure a correspondingly large thermal mass transport with the metallic ones Frame sides of the outer housing are thermally conductively connected.

According to an advantageous embodiment of the invention is the fourth frame side with the adjacent frame ends of the Outer housing via countersunk screws and a female thread as well connected to a coupling element, and the screws are of by means of a two-component adhesive glued metal angles covered to prevent unauthorized access. at the same time The outer housing gives the unbiased viewer a picture a non-openable outer casing.

Three frame sides of the outer housing are at their on Miter cut side ends either glued together or with the interposition of a seal with an internal angle with Screws connected. When connecting the footers with These screws are designed as countersunk screws and are also covered by a glued metal angle. At a Bonding of the frame sides of the outer housing are the two additional angles and screws as well as their screw holes dispensable, however, allows the complete screwing also the replacement of some frame pages.

After a particularly advantageous development of Invention are the coupling elements between the two compact mounting plates of the LED modules near the fourth frame side with this to a fixed push unit screwed. Also advantageous are those of the fourth Frame side of the outer housing facing away from the corners of the Inner housing coupling elements between the two compact Mounting plates provided on which the corner areas over Hitch pins are held.

As a releasable sealant is between the fourth Frame side and the adjacent edges of the transparent Washers and the adjacent frame ends of the outer housing a silicone strip provided. In order also in the inner housing It is easy to separate existing parts from each other Power supply and the control computer in the inner housing via detachable electrical plug-in couplings with each other, with the LED modules and with other built-in components, such as miniature cameras, sensors, Reception units, loudspeakers and microphones, connected.

For high-contrast reproduction of the LED display are the transparent discs of the outer housing on its inside with a transparent color foil occupied. Besides, they are on theirs Outside provided with a two-component glass paint to on the one hand, contrast-sharp contours of the LED display ensure, on the other hand, after a surprising Determination of the Erfmders this glass varnish thermally insulating, especially with a vertical impact of sunbeams.

The fourth, with the inner housing detachably coupled Frame side, which at the same time the underside of the outer housing is provided with two watertight sockets, one of which the one in a conventional manner with an electric Data supply line and the other with an electrical To couple power supply line is what basically from the DE 102 07 264 C 1 is known.

To those in the inner casing and in the interior of the Outer housing heat to be dissipated, are all outer surfaces of the revolving, from one Aluminum alloy existing frame sides of the outer housing with cohesively connected with these frame sides ribs Mistake. These ribs are lapped by air and thus by Air convection and cooled by heat radiation.

These frame sides of the outer housing are advantageous from an aluminum alloy.

The outer housing is advantageous via a screw or Plug-in connection releasably attached to a holder, be it on one Gallows or within an information column or other Mounts, as described for example in DE 102 07 264 C 1 is shown.

According to the figures 1 to 5, the device 1 is made a narrow peripheral frame 2a of an outer casing 2, consisting of a total of two longitudinal frame sides 3, 4 and two narrow frame sides 5, 6 composed. On the bottom Longitudinal side 4 is that of Figures 13 to 17 and 20th and 21 apparent inner housing 7 elevated and thus over screws to be described firmly screwed.

Further, at the lower frame side 4 are two waterproof Sockets 8, 9 arranged, one of which with an electric Data supply line and the other with an electrical To couple power supply line is.

On the frame sides 5, 3, 6 is on both sides according to the Figures 6 to 10 each have a transparent disc 10, 11 with the from the Figures 11 and 12 apparent sealing strip 12 glued. In addition, on the inner surfaces 10a, 11a of the two transparent panes 10, 11 transparent color foils 13, 14 glued. The color foils 13, 14 are mostly red, but can also in other colors, gray, green, yellow or blue be. The outer surfaces 10b, 11b of the transparent disks 10, 11 are provided with a glass varnish.

All frame sides 3, 4, 5, 6 are at their end portions Mitred cut and inserted there in 15 in Connection with screws 16 (see Fig. 1) to a circumferential, closed frame 2a connected.

First, according to FIGS. 6 to 10, the Outer housing 2 via the inner angle 15 and the screws 16 to a U-shaped frame and after gluing the transparent Discs 10, 11 with their colored foils 13, 14 to one Insert housing completed as an outer housing 2. On the fourth Frame side 4 (see Figures 1 and 13) is the in the figures 13 17 illustrated inner housing 7 elevated as follows:

In a first assembly or manufacturing step, the From Figures 18 and 19 apparent light-emitting diodes 17 with their Control semiconductors and their boards by means of a thermally conductive, Double-sided adhesive, not shown here on film Heatsink 18 set of an aluminum alloy. hereby arise strip LED modules 19. Between the not shown, because not visible board and the heat sinks 18th are the heads of screws 20 inserted, which with their Screw shaft penetrate the heat sink 18 in openings and protrude beyond the outer surface, as it is the figures 18 and 19 can be removed.

Then, the LED modules 19 with the same joints 21 and Therefore, the same way over the coupling tabs 22 means Screws 23 to a compact support plate 24 with each other screwed. This results in the outer surface 25 of the compact support plate 24 a uniform grid of Light emitting diodes 17 and on the inside 26 of each Support plate 24 is a continuous support framework, which from the sum of the heat sink 18 of the individual LED modules 19 is formed. On in the corner regions of the support plate 24th located screws 20 are small cylinder 27 with Screwed internal thread, which thereby a Coupling pin 28 for a yet to be described Form plug connection.

To a deflection of one of the two above compact support plates 24 in their central areas too stop, are also - as is apparent from Fig. 18 - in this central region the above-described bolts 20 and be there over wide nuts 29 with a bolt 30th and lock nuts 31 to a spacer with Bracket function joined together.

After the compact support plates 24 according to the Figures 18 and 19 have been joined, they are with their coupling pin 28 at all four corner areas in one Recess 32 of a cubic coupling element 33rd plugged and thus releasably coupled and evenly distanced. The located in Fig. 13 in the lower two corner areas Coupling elements 33 are advantageous, but not necessarily with ever a slot provided as an opening 32 to an orientation enable.

As can be seen from Figures 1 and 13, are the cube-shaped coupling elements 33 in the lower two Corner areas over at least one screw 16 both with the Interior angle 15 and 4 with the fourth frame side fixed connected. This makes the two compact Mounting plates 24 on the fourth frame side 4 of the Outer housing 2 elevated and can so according to the Figures 20 and 21 in the prefabricated according to Figures 6 to 10 Insertion part of the outer housing 2 is inserted like a book become. Before insertion, as shown in FIG. 11, the detachable Sealant 12 a applied to the weather strip 12 to also the fourth frame side 4 splash-proof with the adjacent frame parts of the outer housing 2 to connect. After inserting the are in the two upper corner areas located coupling elements 33 of one screw 35 fixed pulled against the upper frame side 3 of the outer housing 2 and associated with it. Likewise, the upwardly facing leg of the Angle 15 in the two lower corner areas with two Screws 16 on each side of the small frame sides 5 and 6 respectively and / or also with a long screw 35 on the long one Screwed down frame side 4. For alignment, the holes 32 are in the cubic coupling elements 33 in the lower Corner areas formed as slots.

The angles 15 in the two lower corner areas can fastened with their horizontal legs by screws 34 be at the same time in the associated coupling elements 33rd engage in a retaining manner (see Fig. 13).

After in all four corners of the inner housing 2 the cube-shaped coupling elements 33 and thus the Inner housing 7 in the outer housing 2 by the screws 16, 35th are set, the externally visible heads of the Countersunk screws 16, 35 covered by angle 36. These angles 36 be by means of an adhesive, not shown on the Corner areas glued and thus block each unauthorized User access to the screws 16 and 35. To release be the angles 36 in a workshop with a single Hammer hit off and then in reverse order the inner housing 7 from the outer housing 2 by loosening the Screw 16, 35 dismantled without an inner part of the Inner housing 7 or the outer housing 2 must take damage.

As also evident from almost all figures, are the outer surfaces of the frame parts 3 to 6 provided with ribs 37, the particularly clear from the figures 7, 11, 12, 16, 17, 18 and 20 can be seen. The ribs 37 are only in the corner areas for Plan edition of Außenabdeckwinkel 36 recessed, as on most clearly seen in Figures 2 to 5 can be removed. These Ribs 37 carry because of their outer surfaces of the Frame pages 3 to 5 magnifying surfaces for a better Cooling by air convection as well as by radiation at.

From Fig. 21 it can be seen that the watertight Sockets 8, 9 with correspondingly watertight Coupling plugs 38, 39 are to be coupled, one of which with an electrical data supply line and the other with a electrical power supply line is connected.

In the figures 13, 16, 17 and 20 of the inner housing 7 are the power supply 40 and the control computer 41 shown as a block, because whose items are not of interest here. The power supply 40 and the control computer 41 can both directly on the heat sinks 18th the LED modules 19 as well as on a separate Carrier plate 42, 43 are arranged to over this Carrier plate 42, 43 a corresponding heat dissipation to the four frame sides 3 to 6 of the outer housing 2 with the Cooling fins 37 ensure what is not the subject of this Invention is.

The gist of the invention may be summarized as follows: By creating a book like a book as a plug-in unit designed inner housing 7 in an outer housing 2 may be a compact design can be maintained. At the same time both the Inner housing 7 and the outer housing 2 non-destructive in their Parts are disassembled without any of the components doing damage takes. By the elegant use of each one here used LED modules 19 existing heat sink as a support frame Not only can a compact mounting plate 24, but also one compared to conventional LED modules with separate Mounting plates can be ensured even lighter version, because the previously required mounting plates are missing. And finally access to the screws 16 and 35 in the corner areas by the glued angle 36 an unauthorized user locked, but this does not complicate the dismantling.

With this concept, a device is created, despite their training as a plug-in unit of an inner housing 7 in a Outer housing 2 remained compact and yet non-destructive in all items can be dismantled.
