Definitions

  • the present invention relates to a pointing device which can be used in principle in any environment for generating luminous, pictorial or scriptural indications, and particularly preferably their use in environments heavily affected by moisture, contamination or mechanical influences, such as in the automotive sector or in the building sector (typical examples are emergency exits or stairs).
  • From the US-A-5 641 221 is an indicating device with an at least partially breakthrough for generating a typeface, an image representation and / or a string at least partially flat support element which is connected to a flat side with a surface lighting unit on Elektrolumineszens- or Leuchtpolymerbasis, or by means of illuminated acrylic glass to form a backlight is, and wherein the opening is filled with a light for the light unit at least partially permeable filling compound.
  • the DE 199 23 916 A an indication device with a planar lighting unit on Elektrolumineszens- or Leuchtpolymerbasis, or realized by means of illuminated acrylic, as well as an at least partially transparent layer, wherein between the lighting unit and the transparent layer, a sampling is provided by printing or patterning of the transparent layer facing surface the lighting unit and / or by a provided between the lighting unit and the transparent layer decorative film and / or an engraving of the acrylic glass is realized.
  • Object of the present invention is therefore to provide a hint device that can fully develop their hinting effect even in dark or poorly lit environments, it is insensitive to extreme environmental influences and, in particular with regard to a Energy consumption and compact, especially flat dimensions, in addition to the use in building technology also good for mobile use, especially in the automotive sector, is suitable.
  • the information device makes it possible to achieve a backlighting of an advertising or warning message in a flat, compact manner, wherein, in addition to the favorable dimensions, the design of the typeface, the image representation or the character string is at least one breakthrough according to the invention on the one hand the full-area protection of the underlying light unit (by the support element itself or by filled with the filling material breakthroughs) allows, and on the other hand can achieve advantageous optical conditions and maximum flexibility in production, patterning and coloring the desired representation.
  • the result of the present invention is a compact, flexibly deployable and mechanically stable (suitably protected against environmental influences) arrangement, which solves the dilemma of existing, flat and unlit information signs in a surprisingly simple manner.
  • the lighting unit according to the invention can be assigned any voltage supply or control elements which, in addition to a continuous light control, in particular also different light patterns, sequences of individual image or writing elements, flickering or the like achieve otherwise known An horrungswege.
  • the electroluminescent elements preferably to be used for the lighting unit combine pleasant luminous properties with very favorable power consumption and a long service life, so that an instrument suitable in particular for permanent applications has also been found here.
  • electroluminescence is to be understood broadly, so that in particular so-called organic electroluminescence, for example in the form of so-called light-emitting polymers (also referred to as luminous polymers), are encompassed by this term.
  • organic electroluminescence for example in the form of so-called light-emitting polymers (also referred to as luminous polymers)
  • luminous polymers also referred to as luminous polymers
  • the filling compound is particularly preferably a two-component PU casting resin.
  • coloring and level of the Filling material can realize numerous effects, such as a permanent color effect of the generated typeface or the image representation, a (by lens effect correspondingly protruding filling material) resulting, optical enlargement of the typeface, or a special weathering and UV resistance of the typeface by selecting the particular Suitable as a two-component casting resin (such as PU, due to the environmental compatibility, adjustable elasticity or scratch and abrasion resistance) selected filling material.
  • the flexibility for achieving a desired reference design in the context of the present invention is further increased by the protective or decorative film provided on the one hand for permanent interposing between the lighting unit and the carrier element and thus by suitable coloring or patterning the appropriate optical Effect achieved.
  • the permanent interposition of a protective film has the advantage that the light unit is not firmly connected to the filling compound, thereby a simple and economical replacement of the lighting unit allows without the breakthrough must be refilled with filling material).
  • the film may be provided with a primary use as a protective film, only during production, namely for the end-side closing of the opening in the carrier element during filling of the opening with the filling material, in which case, after solidifying the same, the protective film can be removed.
  • This realization form of the invention thus makes it possible to produce the overall arrangement without errors and rejects, since the filling compound can be applied separately from the lighting unit, thus avoiding stress and possible damage to the lighting unit by (still) liquid filling compound.
  • the hint device it should also be pointed out that, according to a preferred embodiment, at the same time also an advantageous development of the main claim, it is possible to solve the sampling directly by means of the luminescent pigment or the luminous area itself applied by a (screen) printing process; in other words, in the context of the combination, the luminescent pigment of the electroluminescent lighting unit would be designed to act as a pattern in its own right.
  • the carrier element can be of any desired design, whereby, depending on the material used, common procedures for introducing the breakthrough are suitable and insofar as the present invention includes any intended use, but with a focus on flat or flat carrier elements.
  • the carrier element made of metal, wood and / or plastic material is made as a plane, angled or curved element.
  • An existing aluminum sheet carrier element 10 has a plurality of corresponding letter contours cut out openings 12, which, as in the Fig. 1 shown, give a visual reference.
  • the formation of the apertures 12 is by means of typical processing methods, for. As punching, (laser) cutting, etc. have been brought about.
  • the openwork lettering in the carrier unit 10 according to Fig. 1, Fig. 2 backlit by a flat lighting unit 14, which is provided in the manner of a strip behind the openings and parallel to the support member 10 extends.
  • the luminous element 14 is realized as an electroluminescent luminous element (in particular inorganic thick-film EL element), ie as a homogeneous luminous surface (in this case strip-shaped), the luminous effect being induced in an otherwise known manner by electroluminescence, excited by a supply voltage which can be coupled to a supply line 16 or by means of a connected ballast (converter) is generated.
  • electroluminescence effective luminous surfaces are well known in the art and available on common distributors in different surface dimensions, maximum intensities and luminances, primary colors, etc.
  • An advantageous feature of the electroluminescent (EL) luminaires preferably used in the context of the invention is a homogeneous light emission without glare point and shadow surfaces;
  • a nearly stepless brightness control is possible, as well as a color temperature change by suitable adjustment of the operating frequency.
  • Further advantages of an electroluminescent lighting unit are, moreover, that - as in contrast to conventional light bulbs - no sudden failure takes place, but aging phenomena or declining performance is gradual, i. by decreasing brightness, expresses. Incidentally, especially in comparison with light bulbs, the life is relatively long.
  • a decorative sheet 20 which, suitably colored or patterned, an individual coloring or color design of passing through the letter cutouts 12 (EL) light allows.
  • this decorative or protective film is attached by adhesive bonding or by means of a (single- or double-sided) adhesive strip.
  • the film 20 receives the role of a protective film: namely, it offers in particular, during the filling of the openings 12 with the Mastic (casting resin) provided separately from the support member 10, the light unit 14, so that damage by the liquid resin is avoided.
  • the protective film 20 makes it possible to either cast (fill) the mounted luminous element or it serves as a (preferably removable) protective film at the time of filling and until the filling material solidifies.
  • the luminous surface to the carrier element 10 (with or without the decorative film 20 therebetween).
  • the EL luminescent film is preferably laminated (with PE), which further increases the electrical and mechanical safety against damage.
  • the filling compound is introduced into the openings 12 in such a way that it protrudes beyond a planar outer surface of the carrier element 10 and forms the bulges indicated by the reference numeral 22.
  • This allows additional optical effects to be achieved, such as by a lens mold of the cast resin bulges 22 (alternatively, it is also conceivable that the entire surface of the support material is covered with cast resin).
  • a particular, mechanically effective advantage of the invention lies in the fact that by a complete or surrounding filling of the openings with the filling material, especially for large-area reference surfaces with accordingly large breakthroughs, possible injury due to sharp edges of the openings (such as for passers-by) can be avoided.
  • the light-emitting element 14 is covered by a housing element 18, so that, with the overall layout still planar, a rearward protection of the light-emitting element 14 can take place against environmental influences - towards the front side (luminous side), this is advantageously already achieved by the aluminum Carrier element 10 and the casting resin filling of the openings 12 achieved.
  • the cover element 18 can in particular also be realized as an (elastic) adhesive foam or as a textile tape, depending on the specific conditions of use.
  • the carrier element is covered with cast resin, for example also within a potted form; In that regard, the composite would then be embedded or encapsulated in the potting material, so that in this respect no separate housing would be necessary.
  • the supply line 16 is connected to a suitable control or voltage supply unit, which can then further suitably adjust suitable luminous parameters of the luminous element 14, in addition to brightness and color temperature possibly also animation effects, such as flashing or dimming.
  • a suitable control or voltage supply unit which can then further suitably adjust suitable luminous parameters of the luminous element 14, in addition to brightness and color temperature possibly also animation effects, such as flashing or dimming.
  • the carrier element for each individual surface of the lighting unit has an associated (single) breakthrough
  • the support member with a breakthrough , which is deposited by a multi-segment lighting unit (such as in the form of an animated company logo, a digital clock or the like.), So that there are any variation options.
  • the present invention is not limited to the embodiment described, so any materials offer as a carrier element, as well as any shapes or configurations of this element.
  • the carrier element can be provided in almost any manner with (indicative) breakthroughs; In addition to the letters shown, these may in particular also be other image or symbol elements, which in turn, depending on the selected material for the carrier, are then cut out or worked out by a suitable manufacturing process.
  • a two-component polyurethane cast resin is suitable as the filling compound.
  • An alternative form of realization of the luminous element 14 envisages the use here of a suitably flat acrylic glass element, which then acts as a light guide for injected light (eg via LEDs) (and the LEDs are located approximately in a bore of the glass element); alternative could be fed external light by means of a light guide.
  • This variant of the invention is particularly effective when illuminating or pointing effects are brought about by a suitable milling of the acrylic glass surface, for example in the form of characters with corresponding refraction effects. Especially at such milled grooves in the surface then enters the light fed into the acrylic glass surface optically effective.
  • a support element (10 in FIG Fig. 1 ) can be completely dispensed with.
  • the hinting effect is achieved by covering a patterning layer on an EL light-emitting element (realized either by an additional foil, or by direct printing / patterning of the light-emitting surface of the EL element) by a cast resin layer as a transparent protective layer. Even such a unit, which realizes additional advantages in terms of small thickness, is suitable for a variety of applications, such as in the automotive or building sector.
