Definitions
- the invention relates to a headlight for vehicles with a bowl-shaped reflector, with a light source assigned to the reflector, with a lens arranged in the beam path of the reflector, which lens from the Reflector collects reflected light and a convex facing away from the reflector Has side, and with a screen surrounding the lens
- Such a headlight for vehicles is known from DE 41 27 403 C2.
- the Headlights have a plastic housing, the front Opening is completed by a translucent lens.
- a light unit is arranged inside the housing and has an ellipsoidal shape Reflector, a lens and an aperture arranged between the lens and reflector having.
- the light unit is used to generate a dimmed light.
- the Lens is surrounded by a screen, which is held on the housing.
- Such Visors are often on the side facing the lens with a reflective surface.
- the screens shield the one hand View into the headlight interior and on the other hand they give it Headlights have a homogeneous, brilliant appearance.
- the disadvantage here is that when the headlights are switched on, the active light emission only through the small one Dimensional lens is determined and thus perceived as dazzling becomes.
- the headlight known from DE 197 04 4766 A1 there is between one ellipsoidal reflector and a lens an annular brightening reflector arranged.
- the fill-in reflector directs light rays that come directly from a inner focal point of the reflector arranged light source emerge from the lens past. This means that when you look at the headlight appears at switched on light source not only illuminates its light source but also the additional brightening reflector, so that overall a larger area is illuminated is as the area of the lens and the subjective glare is reduced.
- the brightening reflector between the lens and the ellipsoidal reflector the view of a holder supporting the lens, the Aperture and the light source located in the inner focal point of the reflector. So that the headlamp is homogeneous brilliant in this area too Appearance, the holder and the bezel must be elegantly designed and be provided with a reflective surface. Through this reflective Surface of the holder can dazzle the oncoming traffic arise.
- the lens itself can be viewed as a light source / illuminant.
- the projection of this light source represents an independent optical system (brightening of the surroundings through lens projection).
- the reflector, the light source and the lens provide the main light beam.
- the luminance generated from the brightening reflector (surrounding reflector) creates a low, homogeneous level of glare in the oncoming traffic area.
- the oncoming driver therefore does not define the lens, but the entire surface of the lens and fill-in reflector as the light-active surface.
- the prerequisite for a pleasant appearance for oncoming traffic is the homogeneity of the luminance distribution over the entire illuminating surface of the brightening reflector.
- the headlight for vehicles has a light unit (15), which in one Headlight housing, not shown, is arranged.
- the light unit (15) can be rigidly connected to the headlight housing or in the The headlight housing can be mounted so as to be adjustable about at least one axis.
- the Light unit (15) has an ellipsoidal reflector (1), in the interior of which Burning location a light source (2) is arranged.
- a light source (2) Incandescent lamp or a gas discharge lamp are used.
- the lamp is in one in the Peak area of the reflector (1) introduced opening (16) and through a socket (17) is held on the reflector (1).
- the lens (3) is over one Lens holder (18) connected to the front edge of the reflector (1).
- the Lens (3) has a flat side (19) facing the reflector (1) and one Reflector (1) facing away from the convex side (4)
- the ellipsoidal reflector (1) is provided on its front with a reflective surface (20) by a Freeform surface is determined.
- the freeform surface cannot be mathematical Function are described, but is chosen freely.
- From the light source (2) outgoing light rays (21) reflected by the reflector (1) produce a Main light beam (12) with one imaged by the aperture (14) Cut-off line (22).
- the main light beam (12) can be symmetrical or serve asymmetrical low beam.
- Light rays (21) run with respect to the optical axis (9) of the light unit (15) inclined downwards at an angle (a).
- the lens (3) with its convex side (4) dips through one Receiving opening (24) of a paraboloid-shaped brightening reflector (5).
- the brightening reflector (5) borders on the edge area of its receiving opening (24) convex side (4) of the lens (3) and is with this edge area on the Lens holder (8) attached.
- Brightening reflector (5) is a reflection surface (6), which is a in each radial section paraboloidal line describes.
- the paraboloid-shaped brightening reflector (5) has a focal area assigned to the lens (3), which in the inside and / or is arranged outside the lens (3).
- the paraboloid-shaped brightening reflector (5) has at least one optical axis (23) which is parallel to the optical axis (9) of the light unit (15) runs.
- the brightening reflector (5) shown in Figure 2 surrounds the lens (3) at a distance and is attached to the headlight housing, not shown.
- the convex Side (4) of the lens (3) has a roughness in the micro area Parts of the light diffuse outwards, while other parts enter the lens totally reflect so that they come out on the other side of the lens.
- This light components deflected by the lens (3) are those on the reflection surface (6) of the Lightening reflector (5) light rays (7), which a secondary light beam (13) produce.
- the brightening reflector (5) shown in FIGS. 1 and 2 is thus to the light unit (15) aligned that its secondary light beam (13) at least for the most part is arranged above the main light beam (12). From the fill reflector (5) generated luminance levels do not create any disturbing effects for oncoming traffic Glare.
- the headlight shows a pleasant for the oncoming traffic Appearance, since not only the lens (3) but also the lens (3) completely surrounding fill-in reflector (5) is illuminated.
- FIG. 2 there is a circumferential line (8) on the convex side (4) of the lens (3) shown, through which optical axes (23) run, which together a Form a cylinder whose central axis coincides with the optical axis (9) of the light unit (15) coincides.
- the optical axes (23) are from the paraboloid lines formed, which result in radial sections through the brightening reflector (5).
- the brightening reflector (5) can be placed in a large screen of a headlight several light units can be integrated. Such screens are either on Headlight housing or a lens attached.

Abstract
Description
- diffus abgestrahlte Totalreflexionsanteile und
- diffuse Anteile durch Brechung an der Oberflächen-Mikrostruktur.
Der Reflektor, die Lichtquelle und die Linse liefern das Hauptlichtbündel. Die aus dem Aufhellreflektor (Umfeldreflektor) generierten Leuchtdichten erzeugen im Raum des Gegenverkehr ein niedriges, homogenes Blendungsniveau. Der entgegenkommende Fahrer definiert somit nicht die Linse, sondern die gesamte Fläche von Linse und Aufhellreflektor als lichtaktive Fläche.
Voraussetzung für ein für den Gegenverkehr angenehmes Erscheinungsbild ist die Homogenität der Leuchtdichtenverteilung auf der gesamten leuchtenden Fläche des Aufhellreflektors. Um eine ideale Homogenität der Leuchtdichteverteilung auf dem Aufhellreflektor zu erzielen, ist eine diffuse Reflexion aus jedem Oberflächenpunkt der Linse vorteilhaft. Diese "Normalen-Rauschen" kann durch eine Mikrorauhigkeit der Oberfläche oder durch Segmentierung, Facettierung, Hammerschlagstruktur usw. erreicht werden.
- Figur 1:
- einen vertikalen mittleren Längsschnitt durch einen Scheinwerfer für Fahrzeuge mit einer einen Reflektor, eine Blende und eine Linse aufweisenden Lichteinheit und einem die Linse umgebenden Aufhellreflektor, der an der Lichteinheit gehaltert ist.
