Definitions

  • the present invention relates to a lighting arrangement, namely a screen suitable for reproducing information.
  • a screen is usually made up of individually controllable pixels, which, viewed from an appropriate distance, then jointly perceive perceived information, for example graphic content or image and / or text contents. If, in a conventional screen, a phosphor with a beam of electrons is excited in the individual pixels, electrically driven light sources are provided as pixels in recent developments, for example in the case of a screen made of light-emitting diodes (LED).
  • LED light-emitting diodes
  • the object of the present invention is to provide a particularly advantageous embodiment of a designed as a screen for reproducing information bulb arrangement.
  • this object is achieved by an arrangement with a plurality of strips, wherein in a strip in the longitudinal direction in each case a plurality of pixels arranged along the strip are provided at least in groups separately controllable lighting means.
  • the plurality of strips are then arranged next to one another on a connecting element and fastened thereto in each case via a detachable connection, with the pixels provided in different strips also having a multiplicity of image elements which are controllable separately from one another in the width direction, which thus jointly form a widthwise and longitudinal direction result in a screen suitable for reproducing information.
  • the invention also relates to the use of such a luminous means arrangement for reproducing information, in particular for displaying image and / or text contents.
  • the basic idea of the invention is thus to provide the illuminants not as a continuous surface element or embedded in such a fixed, but in juxtaposed strips; "Strip” here means a longitudinally related set of bulbs.
  • the connecting element can functionally connect the strips, that is to say, for example, with respect to activation, and / or can be provided as a static support / support element.
  • the strips are each fastened to the connecting element via a detachable connection, preferably at the ends, so that, for example, in the course of maintenance, the set having the illuminant to be replaced can be removed as a strip and replaced or repaired.
  • This has the advantage, for example, in the case of a limited accessible in terms of its surface screen has the advantage that, for example, attached to one of its two ends on the connecting element strip only needs to be solved from one side and taken out of the screen.
  • a screen hanging from a bridge is illustrative, the strips of which can then be removed from the bridge and exchanged, or even assembled.
  • gaps between the strips may also remain;
  • a wind resistance of the screen can be reduced, so this resistance is smaller than in the case of a continuous surface with a comparable overall extent in the width and longitudinal direction.
  • a large-scale screen used in an outdoor area can be reduced by wind forces and thus wear or the risk of direct damage to the screen, such as breakage of a fixture with increased wind.
  • a pixel can be constructed, for example, from a single or from several, possibly also different colors reproducing, bulbs.
  • light-emitting diodes LEDs are provided as light sources, that is to say the screen is an LED module or is this composed of a plurality of LED modules.
  • a strip can be deflected out of its extended position transversely to the longitudinal direction.
  • an attached to the connecting element end of the strip in its relative position to the connecting element remain unchanged (possibly in the context of articulated storage) and the opposite end of the strip are deflected.
  • the strips can thus extend, for example, in calm conditions in a rest position next to each other, hanging down or projecting upwards or sideways, and are then deflected in wind action "like grasses in the wind", so that air passage openings arise and the wind resistance remains small overall or decreases.
  • a strip in particular an opposite end of the connecting element thereof, preferably over an angular range of in this order increasingly preferably at least 5 °, 10 °. 15 °, 20 °, 25 °, 30 ° can be deflected independently of the other strips, light air passage openings can be created due to the lower mass to be deflected compared to a groupwise deflection.
  • the relative arrangement of the pixels in the undeflected strip so for an information reproduction is made.
  • the strips may also be mounted on the connecting element in such a way that both ends are displaceable in their relative position to the connecting element, ie the strip is also deflected as a whole transversely to the longitudinal direction can be.
  • the connecting element can thus be designed, for example, as a frame to which a strip is then fastened approximately at its two ends.
  • the deflectability is realized in a preferred embodiment with an articulated mounting of the strips on the connecting element, particularly preferably with a bearing via a spring element. Air passage openings can then result, for example, by a movement of the strips, for example when a strip is suspended at its two ends via a respective spring in a frame.
  • a strip can also be mounted with only one end on the connecting element, which then accordingly, for example, can extend only along one side, that is not necessarily present as the strip enclosing frame.
  • one end of the strip hinged thereto such as a hinge, a ball joint or turn a spring.
  • a strip is preferably flexible along its length and so bendable transversely to the longitudinal direction, so that even in a preferred embodiment, rigidly mounted on the connecting element strip can be deflected.
  • An advantage may be, for example, that a rigid connection can usually be realized more cost-effectively than an articulated mounting.
  • a further embodiment of the invention relates to a strip which is fastened with only one end to the connecting element and is thus fixed to the connecting element in its relative position to other strips, but otherwise extends from these separately to a free end.
  • this embodiment therefore, neither a strip clamped in a frame on both sides is provided, nor are the ends of the strips opposite the connecting element connected to one another (which is otherwise possible).
  • Another embodiment relates to a downwardly away from the connecting element, preferably to a free end extending strip.
  • the plurality of strips can be fastened with one end to the connecting element and hang from this in the manner of a curtain.
  • the strips can be deflected in the event of a gust of wind and thus reduce the wind resistance of the screen.
  • an additional weight may be provided on an opposite end of the strip of a strip, which may serve as a stabilization of the strip in its rest position. Furthermore, in this way, if the strip is considered, for example, as a physical pendulum, its duration of oscillation can be increased, so that the movement of the strip becomes calmer, that is less fluttery; this may improve the quality of the information reproduction dependent on the relative arrangement of the pixels.
  • a rear side of the screen reinforced with cross members and supporting elements in the case of a continuous screen surface can often remain free for design reasons and can also be used to reproduce information.
  • the hanging, for example, on the connecting element in the manner of a curtain strips can thus have both from the front on the stripes perceptible pixels, as well as in the opposite direction on the "back" perceptible pixels visible; In this case, the front and the rear associated pixels can be realized, for example, with the same bulbs. This of course also applies to strapped in a frame or in any other previously described manner strips.
  • a further embodiment relates to a connecting element, which is a scaffold part, a crane boom, a bridge or a tensioned rope or is provided at one of them.
  • a connecting element which is a scaffold part, a crane boom, a bridge or a tensioned rope or is provided at one of them.
  • a cantilevered framework may be provided with strips extending downwardly from a transverse portion, or a rope stretched between pillars or buildings from which the strips are suspended; traffic bridges are also considered as bridges between buildings, which are provided for example for pedestrians or solely for visual or static reasons.
  • a control unit is provided for driving the pixels, with which the plurality of strips are wholly controllable as a screen. This does not preclude the presence of additional individual control units in the strip, in any case their operation should be synchronized with the overall control.
  • Control signals are preferably distributed to the plurality of strips by a common control unit, and in each case only one supply electronics necessary for the operation of the lighting means, which converts the control signals, are provided in the strips; However, the supply can also be done centrally.
  • the widthwise and longitudinally extending screen has a total area of which at most 80%, preferably at most 70%, and more preferably at most 60%, are covered with stripes (for area comparison, projecting the stripes into one) Seen widthwise and longitudinally parallel plane): between the strips thus remain air passage openings.
  • an air passage is thus ensured regardless of a deflectability of the strips and reduces the wind resistance.
  • a strip preferably has a width of at most 5%, preferably at most 4%, more preferably at most 3%, of a total width of the screen. The strips remain so narrow in relation to the overall width.
  • a strip is designed as a translucent hollow body with luminous means provided therein.
  • the hollow body can thus be diffusely scattered, for example, as light, and thus a rastering of the lighting means can be at least partially blurring or also transparent.
  • a hollow body made of plastic material is provided. The hollow body can protect the lamps and, where appropriate, their supply electronics, for example against the effects of weather, and also has a structuring effect.
  • an additional, independently of the strip mounted, translucent protective sleeve is provided for a strip, within which the strip extends.
  • the protective sleeve preferably mounted on the connecting element, all options described at the outset for a mounting of the strips can be considered, ie the protective sleeve can be held in a frame, for example via respective spring elements provided at the end.
  • the protective sleeves can then be displaced relative to each other, so that air passage openings can arise between the protective sleeves.
  • the strip and the sleeve can not be mounted analogously movable on the connecting element;
  • a rigid strip can be fixed rigidly to the connecting element and only the sleeve can be movable.
  • a relative position of the pixels provided in different strips is fixed, the strips are additionally protected by a sleeve and the wind resistance of the screen remains low due to the mobility of the protective sleeves.
  • each other immovable protective sleeves can also be provided relative to each other immovable protective sleeves, so this example, rigidly mounted on the connecting element or even be attached by this independently about a wall or ceiling; the sleeves then specify a relative position, for example, for insertable strips.
  • the connecting element connecting the strips does not necessarily have in this case a static function, but can also serve only the functional connection, ie joint control.
  • Another embodiment has in each case for the emission of red, green or blue light designed bulbs, in which case lighting means are provided in a pixel for each of the colors, so for example, each color an LED.
  • lighting means are provided in a pixel for each of the colors, so for example, each color an LED.
  • an LED designed to emit the three colors may also be provided.
  • so-called surface mounted devices (SMD) are preferred.
  • FIG. 1 shows a construction crane 1 with a crane boom 2, to which a connecting element 3 via two connecting pieces 4a, b is attached.
  • a connecting element 3 On the connecting element 3, a plurality of strips 5 are provided, each extending from the connecting element 3 down to a stabilized with a weight 6 free end.
  • the strips 5 are arranged in the width direction 7 so that gaps 8 remain between the strips.
  • 60% are covered by the strips, 40% are available as the air passage.
  • each strip 5 are provided in the longitudinal direction (9) 81 and in the width direction (7) 16 each constructed of three LEDs pixels, so that the screen of 144 x 81 pixels is constructed. It can also be more pixels per strip or more strips are provided (not shown for reasons of drawing), so that screens with 2048 x 1152 pixels and more can be realized.
  • the pixels are actuated in their entirety by a control unit 10 provided in the connection element 3 as a screen.
  • the pixels in the black areas are active and the screen is thus the letter "A" again.
  • these are additionally constructed of a transparent flexible material, such as PVC material, so can react to a gust of wind with a deflection transverse to the longitudinal direction 9.
  • a gust of wind coming from the direction 21a from the left deflects the strip 5 to the right, a gust of wind coming from the direction 21b to the left.
  • the deformation is elastic, so that the strip 5 returns after the gust of wind in its rest position.
  • a part of the force acting on the strip 5 is reduced by the elastic deformation and, on the other hand, the gaps 8 are increased to adjacent strips 5 and a passing of the wind is correspondingly facilitated.
  • deflectable shaped strip 5 it would therefore also be possible to dispense with intermediate spaces 8 already present in the rest position.
  • the strip 5 is connected to adjacent strips 5 only via the connecting element 3, so that the free end with the weight 6 can in principle be deflected at any angle independently of the other strips 5 (one by the mounting on the connecting element 3 and a bending modulus of the strip 5 conditional restriction of deflectability is neglected).
  • the weight 6 stabilizes the strip 5 in the rest position, so that it is deflected noticeably only above a certain threshold; as a function of the flexural modulus of the strip 5 can be prevented so too over-restive movement of the strip 5.
  • FIG. 3 shows a strip having a pixel 31 in the width direction 7 and nine (not shown) pixels 31 in the longitudinal direction 9; the screen is made up of 16 of these juxtaposed strips 6.
  • the pixel 31 is composed of three LEDs 32a, b, c, the red emitting LED 32a, the green emitting LED 32b, and the blue light emitting LED 32c.
  • the LEDs 32a, b, c are soldered together with the remaining pixels 31 of the same strip 6 on a printed circuit board 33, in which the electrical supply and signal lines are guided. These are connected to the control unit 10 after insertion of the strip 6 via a contact surface 35 provided in a socket 34.
  • a thread 36 is provided for screwing into the connecting element 3, locking lugs 37 defining an end position, so that on the one hand the pixels 31 are not rotated relative to the screen surface and on the other hand properly assigned for contacting the contact surface 35 provided pins in the connecting element 3 are.
  • the circuit board 33 has a thickness of 1 mm and can therefore be deflected like a bending beam in any case within certain limits perpendicular to the plane of the drawing.
  • a transparent pipe 38 for example of PVC material, provided for protecting printed circuit board 33 and LEDs 32a, b, c, is also flexible and bends correspondingly with printed circuit board 33 in the event of a gust of wind.
  • An analogous arrangement of pixels 31 is provided on one of the shown front sides of the printed circuit board 33, so that the screen is designed both for a view looking at the drawing plane and for viewing from the opposite direction.
  • a screen is also perceived as when viewed from the opposite direction 21b.
  • FIG. 4 shows a construction crane 1, in the crane boom 2 a plurality of strips 5 are mounted between an upper cross member 3a and a lower cross member 3b.
  • five spring elements 41 are provided on each strip 5, each connect an upper end of a strip 5 with the cross member 2a and a lower end to the cross member 2b while doing something under tension.
  • the strips 5 are held by the springs 41 so on the one hand in position, on the other hand, however, remain movable relative to each other, so that a strip 5 in the case of a gust to move a little way and so can form air passage openings.
  • a connecting element 3 of another screen via connectors 4 is mounted; the screen is analogous to that FIG. 1 constructed from each side attached strips 5.
  • the connecting element 3 could be provided, for example, on one of the sake of clarity not shown counterweight.
  • FIG. 5 shows an embodiment with mounted on a ceiling protective sleeves 51, which are transparent and each receive a strip 5.
  • the sleeves 51 and thus the strips 5 are thus horizontal, extending parallel to the ceiling extending, in FIG. 5 a view is shown looking obliquely from above. So it's the back of a screen designed as Decken Kunststoffsrhirm for viewing from below screen.
  • the protective sleeves 51 are mounted on clamps 52 and connecting elements 53 on the (not shown) ceiling, for the sake of clarity, this mounting device is shown only for one end of a protective sleeve 51; at the opposite end and the other protective sleeves 51 are analog mounting device.
  • the protective sleeves 51 with the strips 5 extend over much of their length over a basin 54 filled with water, thus representing a ceiling screen in an indoor swimming pool.
  • the distance 55 between the water and the screen in this example is 5 m, the surface area the screen is thus not accessible from the basin 54 or only with considerable effort; the same applies to accessibility of the area from the pool edge 56.
  • the strip 5 which according to the invention is provided with a connecting element 3 and which are provided in protective sleeves 51, in the case of a defective pixel, the corresponding strip can be detached from the connecting element 3 by removing a plug connection 57 from the basin edge 56 and removed from the protective sleeve 51 become. This is possible with the aid of a ladder placed at the pool edge 56, which simplifies maintenance.
  • FIG. 6 shows a further screen with additional protective sleeves 51 in side view, with only one protective sleeve 51 is completely shown and from the left and right of it arranged protective sleeves 51 each only one edge is indicated.
  • a strip 5 is provided in each case, which is analogous to that of FIG. 3 illustrated strip 5 is constructed; the translucent hollow body 38 is presently not flexible, but designed as a rigid tube.
  • the protective sleeve 51 viewed in the longitudinal direction 9 has a circular cross-section, in which the strip 5 sits centrally.
  • the protective sleeves 51 are each connected at the end via spring elements 61 with a frame 3 and so movable relative to each other.
  • the rigid strip 5 is screwed into the frame 3 (see. FIG. 3 ), So is not only designed as a rigid body, but also rigidly mounted, so that the pixels 31 of different strips 5 have a fixed relative to each other.
  • the protective sleeve 51 provided for a strip 5 can move relative to the frame 3, in contrast to the strips 5, due to the sprung mounting, so that it can escape in the event of a gust of wind and release or expand air passage openings. The wind resistance is thus reduced despite the additional protective sleeve 51 against a continuous screen area.
