Definitions
- Lighting device for the interior of a vehicle and method for producing a lighting device
- the invention relates to a lighting device for the interior of a vehicle according to the preamble of patent claim 1 and a method for producing a lighting device for the interior of a
- the invention relates to a method for illuminating the interior of a vehicle according to claim 14 and the use of a lighting device for the interior of a vehicle according to claim 15.
- a lighting device for the interior of a vehicle according to claim 15.
- Such lighting device has at least one radiation source, of which can be transmitted from radiation and has at least one surface element emanating visible light in response to radiation emitted from the radiation source and entering at the surface element.
- the radiation source in these known lighting devices is a commercially available lamp which emits radiation in the form of visible light in order to illuminate the interior of the vehicle, in particular when the vehicle is stationary. When the light falls on surfaces in the interior of the vehicle, light also emanates from these surfaces, so that these surfaces are visible.
- the radiation sources in the form of light sources are occasionally very bright and are therefore only operated when the vehicle is stationary, so as not to dazzle the driver while driving. While driving, the interior of the vehicle therefore appears
- the invention has for its object to illuminate the interior of a vehicle over a large area, without dazzling the driver by bright light sources.
- the invention solves this problem with a lighting device according to claim 1, with a method for producing a lighting device according to claim 9, with a method for illuminating the interior of a vehicle according to claim 14 and with a lighting device according to claim 15.
- the lighting device comprising at least one radiation source from which radiation can be transmitted, having at least one surface element emanating visible light in response to radiation emitted by the radiation source and entering the surface element
- the radiation source is a source of ultraviolet radiation
- the surface element has fluorescent substances or phosphorescent substances or fluorescent substances and phosphors having slagde substances, wherein emanating from the respective substances in response to excitation by the ultraviolet radiation, the visible light.
- the ultraviolet radiation is outside the visible range and is therefore not disturbing to the driver of the vehicle.
- the fluorescent substances which are especially in the form of optical brighteners, are excited by the ultraviolet radiation and, in response, emit visible light.
- a source of ultraviolet radiation is provided as a radiation source and that the surface element is provided with fluorescent substances or provided with phosphorescent substances or with fluorescent substances and phosphorescent Substances are provided, wherein emanating from the respective substances in response to excitation by ultraviolet radiation visible light.
- a radiation source transmits radiation
- a surface element receives radiation emitted from the radiation source, and visible light emanates from the surface element in response to the radiation entering the surface element
- the radiation source emits ultraviolet radiation
- the ultraviolet radiation excites fluorescent substances in the surface element or excites phosphorescent substances in the surface element or excites fluorescent substances and phosphorescent substances in the surface element, and that of the respective substances in response to an excitation the visible light goes out.
- the starting material is provided in particular over its entire surface with the respective substances. Accordingly, the surface element has the respective substances over its entire surface.
- the radiation source for ultraviolet radiation is either a light bulb, the ultraviolet radiation, a light emitting diode that can emit ultraviolet radiation, or another source of ultraviolet radiation.
- the surface element is any part of the interior of a vehicle, in particular a textile part or a part made of plastic.
- the surface element is at least one element from the group of decorative fabric, door inner lining, headliner, carpet, headrest and armrest.
- the surface element is in particular treated with an optical brightener or made with a starting material which has been treated with an optical brightener.
- the surface element is treated with an optical brightener for producing the illumination device or a starting material is treated with an optical brightener and the surface element is manufactured with this starting material.
- the starting material is treated over its entire surface with the optical brightener or made the surface element over its entire surface with the starting material, which is treated with the optical brightener.
- the surface element is treated over its entire surface with the optical brightener or made with the starting material, which is treated with the optical brightener.
- the optical brightener can be introduced into the surface element or the starting material in different ways.
- the optical brightener is incorporated into the surface element or the starting material by a method of the group consisting of printing, ink printing, padding, spraying.
- the starting material is in particular a yarn.
- the surface element is preferably a knitted fabric, a woven fabric or a knitted fabric.
- the surface element is for example a plastic part.
- the starting material in particular after it has been treated with the optical brightener, is colored in a layer above the optical brightener, at least in some areas.
- the surface element is colored in a position over the optical brightener, at least in some areas. It is or are thus introduced dyes in the surface element.
- the fluorescent substances or the phosphorescent substances display their fluorescent effect or phosphorescent effect only in partial regions of the surface element.
- the surface element has at least one central region, in which the surface element, in particular in the position above the optical brightener, is dyed uncolored or only with pale colors.
- the starting material is correspondingly colored in at least one central region, in particular in the position above the optical brightener, or colored only with pale colors. It can thus reach ultraviolet light to the fluorescent substances or phosphorescent substances, so that either visible light can be emitted directly or the pale colors backlit.
- the surface element further preferably has at least one edge region in which the surface element, in particular in the
- the surface element is colored accordingly in at least one edge region with dark color.
- an illumination device for the interior of a vehicle in particular in the illumination device according to the invention, wherein the illumination device has at least one radiation source, of which can be transmitted from radiation, and has at least one surface element emanating visible light in response to emitted from the radiation source radiation entering the surface element, is provided according to a further aspect of the invention that this illumination device for the provision of at least a safety light is used.
- this illumination device for the provision of at least a safety light is used.
- the illumination device 1 has a radiation source 2 for ultraviolet radiation.
- the emanating from the radiation source 2 ultraviolet radiation is indicated by two arrows 3 and 4 and illustrated.
- the ultraviolet radiation strikes an interior part 5 of a vehicle whose surface is partially defined by a surface element 6.
- the surface element 6 is provided with an optical brightener having fluorescent substances, so that visible light emanates from the surface element 6 in response to the incoming ultraviolet radiation.
- phosphorescent substances may be provided if visible light from the surface element 6 is to emanate even after extinction of the radiation source 2 for ultraviolet radiation.
- the visible light is illustrated by an arrow 7.
- the ultraviolet radiation impinging on the interior part 5 according to the arrow 3 outside the surface element 6 does not lead to the emission of visible light.
- the Surface element 6 therefore acts outside of the interior part 5 unlit. This can be achieved interesting optical effects or create security lights.
