Back sides (10, 14) and/or front sides (11, 13) of the guidance elements are provided with same uncoupling elements such that a light beam is radiated by distribution of luminous intensity produced by the front side of one of the guide elements. The guide elements are arranged in parallel or at an angle. Luminous elements (8) are designed as LEDS or LED chips.

Description

  • The invention relates to a lighting device for vehicles with a housing, in which a first light unit and at least one arranged in Hauptabstrahlrichtung behind the second light unit are arranged, wherein the first light unit comprises a planar light guide with a second light unit facing back, with one of the second light unit facing away from the front side and with a the rear side with the front connecting narrow side, which is assigned as Lichteinkoppelfläche at least one luminous element for coupling the light in the planar light guide, and that the back and / or the front of the planar light guide element is provided with a number of decoupling elements, so that a light bundle of predetermined light intensity distribution can be emitted from the front side of the planar light-guiding element.
  • From the DE 102 07 694 A1 a lighting device for vehicles is known, on the one hand, a first light unit consisting of a planar light-guiding element and a luminous element and on the other hand, a second light unit comprising a reflector and a luminous element. The planar light-guiding element is arranged in the main emission direction in front of the second light unit and covers it completely. On a narrow side of the planar light-guiding element, a row of light-emitting diodes is arranged as light-emitting elements, so that the light emitted by the same is coupled to the narrow side of the planar light-guiding element and then totally reflected on a flat front side and on a rear side opposite thereto. Decoupling elements are arranged on the flat rear side of the planar light-guiding element, so that the light fed in is deflected in the direction of the front side of the light-guiding element and coupled out at the same. The luminous element associated with the reflector is designed as an incandescent lamp which can be switched on and off independently of the light-emitting diodes assigned to the light-guiding element. To form a common light function, the first light unit and the second light unit can be operated simultaneously. Due to the fact that the area and / or the number of decoupling elements continuously increases starting from the narrow side of the planar light-guiding element serving as the light coupling surface, homogeneous light emission can take place over the area of the planar light-guiding element acting as a "light curtain", which are used to produce, for example, a taillight function can.
  • Object of the present invention is to develop a lighting device for vehicles such that in a space-saving manner, the stylistic appearance is expanded without the lighting requirements are diminished in terms of light function.
  • To achieve this object, the invention in conjunction with the preamble of claim 1, characterized in that the at least second light unit comprises a planar light guide with arranged on a front side and / or on a rear side of the same decoupling elements.
  • According to the invention, a lighting device has at least two planar light guide elements, which on the one hand serves to generate at least one light function and on the other hand to meet higher design requirements. For example, by coordinated arrangement of decoupling elements of a first planar light-guiding element and a second planar light-guiding element, a three-dimensional appearance of the lighting device, ie an appearance with depth effect, are generated, wherein the at least two planar light-guiding elements are arranged to save space in a housing of the lighting device.
  • According to a preferred embodiment of the invention, decoupling elements of the first light unit and the at least second light unit are arranged spatially matched to each other, so that in particular an optical depth effect is achieved in the operating state and / or in the non-operating state of the lighting device. The viewer is given the impression that the illumination device has a relatively large depth, at least one such depth, which is greater than the distance of the main emission direction successively arranged planar light guide elements of the first and at least second light unit.
  • According to a preferred development of the invention, an area density of the decoupling elements assigned to the second light unit is at least partially equal to or greater than an areal density of the decoupling elements assigned to the first light unit. By denser zones of decoupling elements on a surface of a rear in the main emission direction second light-guiding element, the depth effect can be further enhanced. In addition, the coordinated arrangement of decoupling elements of the surface light guide elements relative to each other allows additional design options with respect to the radiated from the surface of the lighting device luminous flux.
  • According to a development of the invention, at least two planar light-guiding elements are arranged spaced from one another in the main emission direction, wherein at least two light-guiding elements offset in parallel or at an angle to each other. In an angular arrangement of at least two light-guiding elements, the depth effect can be further enhanced, preferably in conjunction with the distribution of coupling-out elements over the surface of the first light-guiding element or the second light-guiding element.
  • According to a development of the invention, a plurality of planar light-guiding elements are provided which are arranged offset in a stepped manner transversely to the main emission direction. Preferably, at least two adjacent light-guiding elements are arranged partially overlapping one another in the main emission direction, so that a depth separation is generated in which a signal function with a three-dimensional signal image is generated.
  • According to a development of the invention, the planar light guide elements can be assigned the same color light radiating light elements, so that, for example, a tail light function can be generated. Alternatively, however, two light functions can also be generated, for example a tail light and brake light function, the light elements of the one light guide element being connected in the brake light function.
  • According to a development of the invention, the surface light guide elements are assigned differently colored light-emitting light-emitting elements. In a first variant, the first planar light-guiding element is assigned luminous elements of a first color for producing a first light function, for example for generating a taillight function. The second planar light-guiding element lighting elements are associated with a second color, for example, a yellow color to produce a flashing light function. According to a second variant, the first planar light guiding element can also be associated with multicolored lighting elements, for example red-yellow lighting elements, such that in a switching state of the lighting elements the yellow color for generating the flashing light function and in the second switching state the red color for generating the tail light function, for example the lighting elements of the second planar light guide also contribute, is provided. Advantageously, a large number of light functions can thereby be generated to save space.
  • According to a development of the invention, coupling-out elements are arranged on at least one planar light-guiding element in such a way that a partial light bundle can be coupled out on a second narrow side of the light-guiding element opposite the light-coupling surface to produce a further light function. This partial light bundle can serve to generate, for example, a side marker light function.
  • According to a development of the invention, a decorative lens with a contouring can be arranged between two planar light-guiding elements and / or a planar light-guiding element and a housing bottom surface, so that in particular in the non-operating state of the lighting device an angular and predetermined appearance can be predetermined.
