Definitions

  • the invention relates to a flat light element having at least one substrate and a light-emitting, light-emitting coating thereof, which comprises a plurality of light elements electrically connectable separately adjacent to one another in different parts of the surface, to obtain different light effects.
  • DE-CI 101 26 868 discloses a flat luminous element with these characteristics, which consists essentially of a laminated element composed of two substrates and an adhesive layer assembling them, the luminous element itself being disposed in the plane of the adhesive layer. It is made in such a way that only partial (opaque) surfaces emit light, while light can pass through other partial surfaces.
  • Several light elements can be provided which can be separately connected next to each other in different parts of the surface, the electrodes and the current conducting connections being easily maskable under the opaque coating.
  • the light passing electrode may optionally be used in common (mass) for all the light elements. It is thus possible to obtain different light effects, or also control the light intensity in several steps (depending on the respective light surface and possibly its color).
  • a partially transparent window substrate may in the mounted state of the luminous element and for a sufficient surface or luminous intensity, replace as a roof substrate in an automobile a lighting separated from the interior space in a motor vehicle, a a certain amount of light that can still penetrate from above through the glass roof under daylight.
  • DE-A1-1 00 08 302 discloses another flat luminous element, in which the light-emitting surfaces can be arranged on a frame of a transparent cover such as for example a sunroof of a motor vehicle.
  • EP-A2-1.053910 also discloses interior lighting for vehicles based on electroluminescent flat light films. These can be arranged in any places of a vehicle. A differentiated control of the different areas of the surface of a light element is not disclosed.
  • the object of the invention is to provide another field of use for a flat light element of this nature. In accordance with the invention, this problem is solved by the features of claim 1.
  • the features of the dependent claims include advantageous embodiments of this invention. According to the invention, the flat luminous element is therefore enlarged by at least one separate luminous element which, in comparison with a rather diffuse emission from the remainder of the light field, emits directed light.
  • This may preferably be arranged in the same plane as the flat luminous element, ie either at the surface on a single substrate as a support substrate or inside a composite of two substrates.
  • the constitution respectively the arrangement of the flat luminous element is in this case secondary; it can for example be a full-surface lighting, or frame-shaped or structured in the form of a frame.
  • the separate luminous element can in principle always be connected at the same time as the flat lighting unit. Preferably, however, it may be connected and disconnected separately, and the connection means may be arranged both near each separate light element (local control) and away from them. For example, it can also be provided that they are automatically connected when stopping a vehicle.
  • a particularly preferred field of use for such a concentrated light-separated light element is an integrated reading lamp, in a particularly discrete form, in a smooth-surfaced flat element such as for example a roof substrate of a vehicle or a vehicle. sunroof, which allows an occupant in the darkened interior of a vehicle, for example to study or read a road map without disturbing / dazzle substantially other occupants of the vehicle.
  • a separate reading lamp as provided in addition to the normal illumination of the interior space of the vehicle in conventional vehicles, in addition to its volume size and its wiring, can be deleted. With the configuration according to the invention, therefore provides a particularly elegant solution and also economical.
  • lighting or enhancement applications can also be realized, for example the targeted lighting (automatic) of door opening systems or other functional elements in a vehicle.
  • flat light elements are not only suitable for use in vehicles, but they can also be used in buildings or as appropriate for the equipment of premises in shops and homes.
  • lighting of cabinets in which such a light element could be installed as a ceiling or even as an intermediate board and it can provide, in addition to a lighting surface of the interior space, a local lighting accentuated for example by a functional element, structure or particular design.
  • an optical device is provided in the area of the surface covered by the light element. This may be a simple lens, which is provided either directly on the light element or on or in a substrate covering the latter in the direction of emission of light.
  • Such a lens may optionally also be shaped in a glass or plastic cover element or substrate (by lapping, pressing) or may also be placed in a cavity of the element as a separate part.
  • This latter variant may be advantageous when the face provided with the lens is placed inside a laminated element, so that the outer surface of the substrate can remain smooth.
  • a flat lens which itself has only a very small thickness, but which nevertheless ensures a good concentration and a good orientation of the light.
  • both plastic and glass could also be placed outside on the element or substrate cover.
  • holographic element spatial hologram
  • Such holographic elements can be made in the form of films with microprisms, which can provide very precise orientation and concentration of light for negligible thickness. With these, one can even obtain angles of deviation particularly large compared to the normal direction of emission perpendicular to the plane of the substrate (see for this purpose for example DE-CI 195 12 864 or DE-C2 197 03 398) .
  • FIG. 1 is a view of an embodiment, in which a roof element or substrate with a full-surface halftone illumination in a manner known per se comprises two separate luminous elements
  • FIG. 2 shows a sectional view of the principle of FIG. 1 along line II-II
  • FIG. 3 shows a detail variant of a sectional view as in FIG. 2
  • FIG. 4 shows another variation of detail of a sectional view as in FIG. 2.
  • FIG. 1 shows a rectangular light element 1 of rectangular shape with an opaque frame 2 and a light field 3. The latter is configured in known manner in a frame, which consists of light-transmitting surface portions and opaque surface portions. This screening is however not necessary for the operation.
  • the flat luminous element 1 is made in the form of a laminated element with a first substrate 1.1, a second transparent substrate 1.2 and an adhesive layer 1.3 assembling the two substrates flat to one another. Between the adhesive layer 1.3 and the substrate 1.2 is arranged a flat electroluminescent element 3.1, optionally arranged on a clean support film, which forms the light field 3.
  • an optical device 5 is provided in the form of a planar lens inserted in the laminated element, which concentrates and directs the light emitted parallel by the separate light element 4, as indicated schematically by a cone of light 6.
  • the light is emitted substantially perpendicular to the plane of the substrate.
  • This optical device 5 ' is a film hologram, which is here bonded to the outer face of the substrate 1.2.
  • This hologram could also be inserted into the laminated element, such as the flat lens 5. However, it must be compensated for or taken into account, where appropriate. from the refraction of light to the transition between the substrate 1.2 and the atmosphere.
  • the structure shown in FIG. 4 shows an embodiment suitable for this purpose, which may be a combination of the embodiments of FIGS. 2 and 3. In this case, the optical device 5 'is located inside. It is again used for the orientation and / or concentration of the light emitted by the light element 4.
  • this outer surface is provided with an appropriate antireflection layer 7. This can be provided locally, therefore only at the desired output location of the light beam, or on the whole surface.
  • the light source itself (light element 4) with an opaque coating disposed thereon and thus possibly a protection against glare.
  • the light is deflected in the transparent substrate 1.2 along the coating and then leaves only at another location of the substrate 1.2.
  • the light can be conducted in a manner known per se first at a distance in the glass or plastics material of the substrate and then again conducted outside at a predetermined location using an anti-reflective layer or other optical device.
