Definitions

  • the present invention relates to a luminaire arrangement, in particular in the automotive sector.
  • Luminaire arrangements in the automotive sector serve road safety. With their help, the roadway is illuminated in front of the vehicle in the dark or poor visibility. Further, the lamp assemblies serve to visualize the motor vehicle for subsequent vehicles by either emitting light or by reflecting the light from the subsequent vehicle.
  • luminaire arrangements in the motor vehicle sector are more subject to influences of the vehicle design than previously. Therefore, meanwhile, in the construction and design of headlamps for vehicles to take account of boundary conditions that played only a minor role in the development and construction of lighting arrangements or headlamps a few years ago. For example, in vehicle lights or vehicle headlights, a brilliant, transparent appearance of the luminaire is now desired. For this purpose, find brilliant, transparent cover plates use that cover a receiving area of the housing. Due to these transparent cover plates a very good view of the headlights or lighting arrangements from the outside is possible. It is desirable for visual considerations, a modern design, such as a tube design to realize.
  • a luminaire assembly is often provided with a trim to highlight the visual appearance of this luminaire assembly.
  • a trim is usually a one-piece or composed of several parts panel, which should give the luminaire assembly a particularly high quality characteristics.
  • the luminaire arrangement provided with a trim panel can be arranged, for example, in the receiving area of the housing behind the transparent cover, so that not only the luminaire arrangement itself but also the respective trim panel can be seen from the outside.
  • the publication DE 199 06 527 A1 describes generally a lighting arrangement for a motor vehicle with a cover and a housing in which a double Ellepsoid headlight is arranged, the one Incandescent lamp having a reflector.
  • a diaphragm is provided, which fixes the double Ellepsoid headlights and which has a conical shape.
  • the lens may, in strong sunlight to focus the reflected sunlight on underlying parts of the headlight or the aperture lead, which are thereby thermally damaged.
  • a solution known to the Applicant provides for the high-gloss finish of the components in the focal point of the lens with respect to the solar radiation in order to reflect the heat radiation.
  • the aperture of the lamp assembly with an additional radiation protection element to provide protection element, which is designed as a single part high gloss.
  • the heat protection elements must be made in a separate tool by means of a separate manufacturing process and surface treated for a reflection of the bundled solar radiation. This represents a complex and costly additional effort. Furthermore, the heat or radiation protection elements must be fastened by means of fastening devices on the diaphragm device, which represents a further disadvantageous process.
  • the DE 202 09 130 U1 describes a headlamp for a motor vehicle with at least two chambers for receiving a lamp, each lamp having at least one light source and a light source associated reflector for generating the light distribution.
  • the chambers are separated by a dividing wall photometrically.
  • the US 5,021,930 relates to a vehicle headlight construction in which the chromatic aberration is essentially eliminated.
  • the headlamp includes an elliptical reflector, a light source disposed at a first focus of the elliptical reflector, a condenser lens substantially focused on the second focus of the elliptical reflector, and an outer lens provided in front of the condenser lens.
  • the radius of curvature of the outer lens is reduced in its vertical center portion to thereby form an angled portion through which the light passes from the light source.
  • the DE 20 2004 012 321 U1 describes a cover frame for a headlight of a motor vehicle with a receptacle for at least one light module, wherein the cover frame consists of a processable in particular by injection molding plastic, characterized in that in the region of the receptacle for the at least one light module, a heat protection component for thermal separation of the light module from the cover is provided.
  • the present invention is therefore based on the object to provide a cost-manufacturable lighting arrangement in which the exposed to excessive heat radiation components of the lamp assembly are protected from heat damage.
  • the luminaire arrangement has a housing for accommodating at least one light source, a base ornamental panel device for covering non-technologically relevant sections of the luminaire arrangement in the housing and at least one additional ornamental panel means, which can be attached to the base ornamental panel device and at least one radiation protection section having a high reflection coefficient.
  • the present invention has the advantage over the prior art that the luminaire arrangement consists of fewer individual parts and thus the manufacturing and assembly costs can be reduced due to the reduced process steps, since the necessary radiation protection is already designed as part integrated in a decorative screen means.
  • the additional decorative panel means can be prepared together with the radiation protection element in a single tool by means of a single manufacturing process and holistically surface-treated by means of a common treatment method. This reduces, as already explained above, both the manufacturing and the installation costs.
  • the at least one additional ornamental panel means consists of the at least one radiation protection section and an aperture ring integrally formed with the at least one radiation protection section.
  • integrally formed diaphragm ring is attached to an associated cylindrical pipe section of the base trim device.
  • the aperture ring serves primarily to create a visually pleasing overall impression of the luminaire arrangement from the outside.
  • the at least one radiation protection section is formed as an extended reflection section protruding from the diaphragm ring in the axial direction for reflecting the radiation incident from a lens accommodated by the base ornamental shutter device.
  • the at least one radiation protection section protrudes in the installed state of the additional ornamental diaphragm means in the axial direction from the underside of the diaphragm ring.
  • the radiation protection portion is in the reflected from the lens beam path of the sun and protects under the radiation protection portion located portions of the lamp assembly from heat damage.
  • the at least one radiation protection section is arranged in the respective focal point of the lens of the luminaire arrangement with respect to the solar radiation reflected by the lens for protection of underlying components of the luminaire arrangement.
  • the radiation protection section for example, as a protruding tab with rounded peripheral edge or the like be formed in order to make the overall visual impression of the luminaire arrangement positive.
  • the at least one additional ornamental panel means integrally made of a suitable plastic and is produced in a holistic mirror-finished.
  • the high-gloss mirroring provides the additional decorative means and thus also the radiation protection portion a high reflection coefficient, so that this reflects the incident solar radiation for heat protection from the light assembly well out.
  • the visible surfaces of the additional ornamental panel means advantageously have a coating to ensure the high-gloss mirroring, wherein the coating may contain, for example, aluminum, chromium and / or silver or an alloy thereof.
  • the at least one additional ornamental panel means comprises a fastening means for releasably attaching to the base trim panel means.
  • the fastening device may be formed, for example, as a plug-in, clips and / or latching connection.
  • the lighting arrangement comprises a turn signal lamp, a dimming lamp, a floor lamp, a high beam, a stop lamp, a warning lamp and / or a reflex area, wherein each of these lamps or areas may each be formed with an additional decorative panel according to the invention with integrated sun protection device.
  • the light assembly 1 is made Fig. 1 preferably provided in an associated body portion of a motor vehicle.
