Definitions

  • the invention relates to a lamp device, in particular for a motor vehicle, consisting essentially of a housing covered with a clear, optically inactive cover pane, in which at least one lamp, formed from a lamp with an associated reflector, is arranged.
  • Lighting devices of motor vehicles in particular headlight combinations, increasingly have clear cover panes without an optical function.
  • the light distribution to be generated for the lights located behind the cover plate is realized by appropriate design of the reflectors and the associated lamps. This requires a certain depth, surface structure and symmetry or asymmetry of the components used.
  • the reflectors are adjustable, for example to enable the headlamp leveling to be adjusted to the particular load on the vehicle.
  • the light sources or lamps for example incandescent lamps or gas discharge lamps, can be covered by additional caps.
  • the clear cover disks are now also required due to design specifications.
  • the requirements of the vehicle design also have to take into account the overall visual impression of a lighting device, since it should fit harmoniously into a given vehicle body.
  • a headlight arrangement is known from US Pat. No. 5,010,458, which is covered with a clear lens.
  • Different reflector parts in the interior of the arrangement can have certain colored coatings that are matched to the vehicle paint finish.
  • the cover lens appears to the viewer in the color of the surrounding body.
  • a reflector housing and a lamp covering can be coated in the color of the adjacent body parts.
  • the reflector itself can also be coated in color.
  • a colored, partially permeable metal layer is vapor-deposited on the reflector surface, which on the one hand makes the reflector appear colored and on the other hand emits the light reflected from an underlying base coating when the lighting is switched on from the base coating to the outside without changing the color.
  • a disadvantage of the known arrangement is that, despite the appearance of the headlamp which is color-coordinated with the surrounding body, when the lighting is not switched on, the technical details of the structure are visible at least in a close range. This applies in particular if the reflector is covered with a clear cover plate instead of a lens. In the case of luminaire combinations which have differently colored lamps, for example yellow flashing lights, there is also no uniform appearance.
  • a technically necessary reflector and lamp design should influence the overall appearance of the lamp device as little as possible.
  • a cover designed as a partially transparent mirror is arranged between the cover plate and the lamp, the rear, the lamp receiving lamp compartment from a front, through the panel and the cover pane formed separates the luminaire space so that the rear luminaire space is not visible to an observer looking in the direction of the luminaire and the cover is transparent to the light emitted by the lamp when the lighting is switched on.
  • the cover fulfills the function of protecting the rear light room.
  • the light emitted by the lamp or lamps can pass through the mirror unchanged or at least almost unchanged.
  • the entire luminaire device Due to the reflective surface and the relatively flat front luminaire space defined by the panel, the entire luminaire device has a very "flat" design, which is perceived as optically advantageous. Since the reflectors and luminaires are not visible, their shape and surface can for an optimal light distribution, regardless of the visual impression they convey.
  • the luminaire device conveys a high-quality, subtle visual impression while being compatible with the use of luminaire components of the highest lighting efficiency.
  • the diaphragm consists of a base plate, which is on a front side facing the cover plate has a partially permeable metal coating applied by means of a vapor deposition process.
  • a vapor-deposited metal layer can be used to produce a partially transparent mirror in a simple and inexpensive manner.
  • the thickness of the metal layer is preferably in the wavelength range of the visible light, so that it fulfills the requirements for the partially transparent mirror with respect to the invisibility on the reflecting front side and the permeability of the light emitted by the lighting device when the lighting is switched on.
  • a suitable dielectric coating of the base plate of the diaphragm from one or more layers is also conceivable for realizing the partially transparent mirror.
  • the base plate consists of a clear plastic.
  • the plate made of clear plastic is easy and inexpensive to produce in the desired shape. It is light in weight and can be easily arranged and held in the lamp device.
  • the clear plastic ensures that the light from the light bulbs or gas discharge lamps of the luminaire or luminaires can pass through the base plate at least almost unchanged.
  • the screen has a contour adapted to the lights.
  • the contouring of the diaphragm preferably traces the reflector shape. If there are several reflectors in the lamp device, the same applies to the other reflectors. This creates the impression of a headlight without emphasizing the technical details too much. The impression is subtle but not too abstract or unrealistic, which further improves the overall impression of the lighting device.
  • the screen is in a receptacle in an edge of the housing and / or in a receptacle in a nem edge of the cover and held flush and tight with the edge of the housing and the edge of the cover.
  • the mounting of the cover in a receptacle for the edges of the housing and the cover enables the components to be fixed particularly securely when the lamp device is assembled.
  • a circumferential groove can be provided in the edges of the housing and the cover disk, into which a circumferential projection of the panel engages on both sides. Sealing rings can also be provided on both sides for sealing purposes.
  • a firm and tight connection of the components can be achieved by a detent, which locks the parts together when they are joined and seals them tightly.
  • the connection or the detent can, for example, be designed to be releasable for exchanging a defective cover plate. This has a favorable effect on any maintenance and repair costs that may arise.
  • the panel is firmly connected to the edges of the housing and the cover plate by gluing.
  • the panel By gluing the components to the edges, the panel can be installed in a simple and particularly cost-effective manner.
  • the panel is attached to an inside of the housing.
  • the cover can also be on the inside, i.e. be attached to the inner wall of the housing in a simple manner.
  • the cover can also be on the inside, i.e. be attached to the inner wall of the housing in a simple manner.
  • the screen is attached to an inside of the cover plate. Attaching the cover to the inside of the cover plate creates a one-piece component, which has a cost-effective effect on the assembly costs.
  • measures to compensate for thermally induced material stresses are provided on at least one connecting section between the cover and the housing and / or the cover plate.
  • measures to avoid material tension between the housing, cover and cover components prevent the risk of cracks due to different thermal expansions of the components during operation of the luminaire and from external influences such as frost or direct sunlight. This has an extended effect on the life of the lamp device.
  • the measures can be formed on one or more connecting sections, for example as expansion joints or recesses.
  • Adequate thermal relief can be ensured, for example, by rear ventilation or other measures for heat dissipation of heat generated in the rear luminaire room.
  • the design of the lamps and the reflectors in order to generate a defined light distribution in each case, can be adapted to an interaction of the light emitted by the lamps with the diaphragm.
  • the lamp and the reflector that is to say the components of the luminaire
  • the components of the luminaire can be adapted to an interaction of the light which they emit with the diaphragm, a light distribution to which particularly stringent requirements are placed can be precisely observed.
  • the components of the division might be impaired, the components of the luminaire or luminaires can be adapted in terms of design or by a suitable selection of the components. Since the rear luminaire room is not visible, this can be done without impairing the optically high-quality impression of the luminaire device. By adjusting the lights, the influence of the cover on the light distribution can be compensated for.
  • Figure 1 A plan view in section of a lamp device.
  • a lamp device essentially consists of a housing 5, with a lamp 11, an aperture 7 and a cover plate 1.
  • FIG. 1 shows a front light combination with a second light 11 '.
  • the lamp 1 1 can for example be designed as a position and daytime running lamp and the lamp 11 'as a flashing light.
  • the lights 11, 11 ' are made up of an incandescent lamp 4 or 4' and an associated reflector 3 or 3 'and are fastened in the housing 5 in a known manner and connected to a voltage supply and a switching device of the vehicle ,
  • the housing 5 is covered with the clear cover plate 1, which is advantageously designed as a contoured glass plate adapted to the shape of the headlights and the surrounding body. To simplify the illustration, only a rectangular shape is shown in FIG. 1.
  • the housing 5 and the cover plate 1 have peripheral edges 12 and 13, between which the diaphragm 7 is mounted, for example in recesses or receptacles (not shown).
  • the diaphragm 7 is firmly connected on the one hand to the housing 5 and on the other hand to the cover plate 1, for example via a catch (not shown), so that the lamp device is sealed off in the area of the connections.
  • the connections can also be simple adhesive connections.
  • a rear lamp compartment 9 is separated from a front lamp compartment 10 by the panel 7.
  • the rear lamp compartment 9 receives the lamps 11, 11 'and is formed by the housing 5 and the panel 7.
  • the front lamp compartment 10 is formed by the panel 7 and the cover 1.
  • the panel 7 itself consists of a base plate 2, advantageously made of clear plastic, and is vapor-coated on a front side facing the cover plate 1, ie on one side, with a partially permeable thin metal layer 8, advantageously a silver layer. A partially transparent mirror is thereby formed.
  • the aperture 7 appears as a mirror when the lighting is switched off.
  • the rear lamp room 9 is not visible to the viewer.
  • the light emitted by the lamps 4 or 4 ′ can radiate outward unhindered with the respective light distribution generated by the reflectors 3 or 3 ′.
  • contours 6 or 6 are formed in the panel 7.
  • the contours 6, 6 ' trace the shape of the respective associated reflector 3 or 3'.
