Definitions

  • the invention relates to a light or lighting device, in particular for Motor vehicles with a housing, a lens and a light source.
  • the basic design for a lighting device according to the reflection type is that at the foot of the burning or Light source is surrounded by a parabolic reflector. In front of the reflector, d. that is, in the half space into which the light is emitted, there is a holding device, which is usually provided with a lens. It tries the light Uncouple from the reflector zone and bring it onto the lens system.
  • Other known variants consist of one between reflector and lens provide cylindrical sheath that captures stray light. It is essential that the Headlight projection lens in known headlights or lighting devices collect all the available light and throw it forward.
  • the light emitting Surface or the light exit surface or light exit plane is through the outer surface of the Headlight lens given.
  • a vehicle headlight has the task, in particular in To ensure direction of travel an illumination of the road in the dark and at the same time for oncoming vehicles the signal image for an approaching To represent vehicle.
  • This double task is considered in the state of the art multiple headlamp arrangements are known, in which attention is paid to the light to bundle as well as possible.
  • This in turn has multiple disadvantages.
  • a headlight for vehicles which according to Projection type works.
  • the headlight consists of a reflector, one Light source, an aperture and a downstream lens.
  • the luminous flux is in its basic vertical and horizontal settings with respect to a longitudinal axis of the headlamp adjusted by vertical and horizontal displacement of the lens.
  • the said Lens be mounted eccentrically to the longitudinal axis of the headlamp and essentially around Headlamp longitudinal axis can be rotatably arranged.
  • the said Luminous flux distribution as such in the foreground.
  • the headlight throws the total amount of light forward. It becomes known, as in others Systems tries to get as much of the amount of light down on the road in one radiate directed angle. This tries to dazzle oncoming traffic to achieve this by appropriately turning away the light cone.
  • a lamp for a vehicle in which one Shield is arranged in the light path between the reflector and lens, the one Shadowing or changing the light distribution causes. It should be achieved that the light beam has a reduced sharpness in the edge area. This means with others Words that the light beam is diffusely scattered outwards from an inner core area becomes.
  • the shielding element is placed in the direct light path, one is not insignificant part of the available core light, not the stray light, is shaded and is no longer available for the pure illumination function.
  • a headlight is known from DE 41 02 586 A1, which has a correction device for correcting a light distribution characteristic provided by an inclination of a body part is caused with respect to a roadway. Covering agents are used for this used, which change with the inclination of the vehicle or the body part. Such a design is used in motorcycles. But here, too, the glare in the Oncoming traffic not avoided.
  • EP 0 623 780 A2 is one Vehicle headlight projection lens known to produce a Low beam pattern is designed so that the convex emission surface of the lens has different imaging sections, one above the horizontal plane upper section lying through the optical axis and one below it Horizontal plane lying lower section is provided, with at least two lower Sections are provided, one of which is on the horizontal plane to the side Lens edge facing pending upper boundary, or a continuously different imaging surface is provided.
  • the light beam is in total Split segments. This only leads to a fanning out of the actual one Light cone. Avoiding glare is also not guaranteed here.
  • a headlight in which the beam path of the A lens is arranged reflector, which is held in a carrier element.
  • the Carrier element is translucent.
  • the light transmittance can e.g. B. by a Coating or matting can be influenced.
  • the object of the present invention is therefore based, a light or lighting device, especially for motor vehicles Generic type to the extent that while maintaining an optimal Illumination of the roadway the signal image function of the device is glare-free.
  • the task is at a light or lighting device, especially for Motor vehicles, according to the preamble of claim 1, according to the invention the characterizing features of claim 1 solved.
  • a first partial surface of the lens is optical Has deflection properties, in particular is designed as a lens, and the main part of the available light for illuminating the road is aimed at the same, and one second partial area uses the remaining and / or scattered light which Oncoming traffic is facing as a signal image.
  • the remaining rest and / or stray light occurs through a gap provided between the reflector and the lens in the Housing, is diffusely reflected there and finally exits through the second partial surface.
  • the further glare-free weakening of said light part in said annular outer area can be achieved in that the inner surfaces attenuating or having a defined transmittance are mirrored.
  • the inventive design of the lighting device total available luminous efficacy of the light source used.
  • the core area i.e. i.e., in said middle area is used to illuminate the road, for example by a Lens, the main part of the light averted from oncoming traffic and towards the road Illumination directed.
  • Only the outer area is counter to oncoming traffic only uses the residual light component, whose attenuation also, as already executed, can be achieved by partial metal vapor deposition.
  • the lighting device can be of the reflection type that a reflector is arranged behind the light source.
  • the reflector can be positioned in relation to the light source such that the Core light reflection can be projected onto the central area of the light exit surface, and the remaining scattered light yield illuminates the outer area.
  • the central area can be formed by a lens, or such a lens contain.
  • the outer area is mirrored such that the said scattered light component translucent from the same from the light source X-rayed and appears to be reflected when the light comes from the front.
  • Figure 1 shows a section through a headlamp designed according to the invention.
  • the same is arranged within a housing 30.
  • the essential elements are the Light source 1, which is arranged centered in a reflector 2. This is from the Light source 1 emitted light via the reflector 2 essentially onto the one in front arranged first partial surface 11, which is designed as a lens, directed.
  • the said Lens 11 is arranged in the central region of the lens 21.
  • the quasi stray residual light, which within the Housing 30 is scattered and at least no longer directly from the lens 11, i.e. on the predetermined focus is brought, the second partial area 22 of the Reach lens 21.
  • the second partial surface 22 is mirrored such that the residual light present in the housing 30 is definitely the partially mirrored second partial surface 22 can shine through.
  • the partial mirroring of the second partial surface 22 is designed in this way or to be understood in such a way that the residual light present in the lamp housing 30 said can penetrate mirrored annular second partial surface and only a little is dampened.
  • the said mirroring to this extent gives a front view, i.e., looking at the same or the cover from outside the housing, one Mirror effect again, so that you can't get into the same from outside the case can look inside.
  • the contour 23 of the lens 21 only forms a ring, in which either the lens 11 is recessed or a transition from the rest of the cover in the Includes lens area.
  • the lens 11 can also be incorporated into the cover be so that lens 11 and lens 21 are in one piece. That is, inner area 10 and The outer region 20 of the cover 21 then merge into one another.
  • FIG 2 shows only the arrangement of the lighting device in one Installation slot 40.
  • the installation slot 40 can be located, for example, in the front area of the motor vehicle are located on both sides next to the radiator slots. It is clear to see the delimitation of the actual lamp cover 21 in the central region 10, which the Includes lens, as well as the outer second partial surface 20.
  • This causes the reflector 2 Core light of the lamp projected onto the lens through the central region 10, i. i.e., the lens arranged behind or in front of it leaves the lamp housing.
  • This cone of light serves for illuminating the road and is directed towards it, i.e. from the Oncoming traffic field of view dimmed.
  • the residual light within the lamp housing is attenuated and emitted to the outside. That is, for oncoming traffic there is a brightly illuminated, dimmed central circular area and an annular surface emitting with a second effective illuminance outside.
  • the light cone 10 leaving the central area is oncoming traffic dimmed, but can be seen as a much lighter circular area.
  • the outer ring surface is dampened, so that overall there is a signal image for oncoming traffic. That is, everything Light is divided accordingly, the central area is only focused on the road, d. dimmed, and the circular ring area as a signal image for oncoming traffic in facing the light-attenuated way.
  • webs 11 are arranged in the contour of the cover, which only for fastening the circular ring 23 shown in Figure 1 for receiving the Serve lens 11.
  • the representation of the webs 11 is only schematic and is required in no other execution here.
