Abstract
A Lighting device, in particular lighting device for a vehicle, is provided comprising at least one light source from which light is emitted during operation of the lighting device. A first flexible foil is also provided through which the light emanating from the at least one light source passes at least partially. The first foil influences the light passing through in such a way that directed light emerges from the first foil. The lighting device also comprising a second flexible foil into which the at least one light source is integrated or on which the at least one light source is arranged.
Claims13
A lighting device for a headlamp in a motor vehicle, the lighting device comprising:
- at least one light source from which light is emitted outwardly from the motor vehicle during operation of the lighting device;
- a first flexible foil through which the light emanating from the at least one light source passes at least partially, the first flexible foil influencing the light passing through in such a way that directed light emerges from the first flexible foil, the first flexible foil having a first side facing the at least one light source and a second side opposite the first side, the directed light emerging from the second side of the first flexible foil;
- a second flexible foil into which the at least one light source is integrated, the second flexible foil having a first side and a second side opposite the first side, the second side of the second flexible foil facing the first side of the first flexible foil;
- a flexible spacer positioned and located between the first flexible foil and the second flexible foil to provide a distance between the first flexible foil and the second flexible foil, wherein the flexible spacer comprises a frame that is separate from the first flexible foil and the second flexible foil, wherein the frame abuts the first side of the first flexible foil, and wherein the frame abuts the second side of the second flexible foil;
- an aperture being defined by the frame of the flexible spacer and extending through the flexible spacer;
- an adhesive arranged on the first side of the second foil to fasten the lighting device to a surface;
- and
- a heat conducting paste arranged on the first side of the second foil for dissipating heat generated by the at least one light source, wherein the adhesive surrounds the heat conducting paste;
- wherein the at least one light source extends into the aperture such that the aperture forms a gap at least partially surrounding the at least one light source;
- and
- wherein the at least one light source is located entirely below the first flexible foil.

A lighting device for a headlamp in a motor vehicle, the lighting device comprising:
- a plurality of light sources from which light is emitted outwardly from the motor vehicle during operation of the lighting device;
- a first flexible foil through which the light emanating from the plurality of light sources passes at least partially, the first flexible foil influencing the light passing through in such a way that directed light emerges from the first flexible foil, the first flexible foil having a first side facing the plurality of light sources and a second side opposite the first side, the directed light emerging from the second side of the first flexible foil;
- a second flexible foil into which the plurality of light sources are integrated, the second flexible foil having a first side and a second side opposite the first side, the second side of the second flexible foil facing the first side of the first flexible foil;
- a flexible spacer positioned and located between the first flexible foil and the second flexible foil to provide a distance between the first flexible foil and the second flexible foil, wherein the flexible spacer comprises a frame that is separate from the first flexible foil and the second flexible foil, wherein the frame abuts the first side of the first flexible foil, and wherein the frame abuts the second side of the second flexible foil;
- a single aperture being defined by the frame of the flexible spacer and extending through the flexible spacer;
- an adhesive arranged on the first side of the second foil to fasten the lighting device to a surface;
- and
- a heat conducting paste arranged on the first side of the second foil for dissipating heat generated by the at least one light source, wherein the adhesive surrounds the heat conducting paste;
- wherein the plurality of light sources each extend into the single aperture;
- and
- wherein the plurality of light sources are located entirely below the first flexible foil.
