Definitions
- the invention relates to a headlight according to the projection type for motor vehicles one or more lamps, at least one reflector and a lens according to the preamble of claim 1.
- Headlights of the projection type are standard in today's motor vehicle construction.
- the headlamp consists of a lamp according to the type of projection, which is arranged in the focus of a parabolic reflector.
- the said lamp i.e. the lamp must be held in an appropriately fixed position, this fixed position must also be fixed relative to the reflector.
- a Adjusting the lamp element out of focus leads to defocusing the actual illumination or the light cone generated.
- projection lenses which are made from the Collect reflector emerging light and accordingly the light cone produce.
- the headlight according to the projection type consists of a converging lens with an annular frame. In essence this frame only supporting functions. A further function, also more optical Art does not belong to this frame.
- the invention is therefore based on the object in installation space-minimized headlights the generic type to an optical enlargement of the headlight design achieve without increasing the overall length or the overall depth as such or need to enlarge.
- the task is for a headlamp according to the projection type for Motor vehicles according to the type of claim 1 solved according to the invention in that that the optically active, i.e. directly illuminated lens diameter by one optically edge area that is not active or not illuminated is expanded.
- magnification does not use an element that has a larger one Space constrained.
- the essence of the invention is essentially that the optical enlargement is accomplished by an element that is already in the Space of the headlight is available and necessary, but is now designed and is placed to serve the above purpose.
- said edge area is through an annular element placed on or attached to the lens is formed.
- This circular element is already inside the headlight, for example because the lens is somehow fixed in position got to.
- This element that is to say already with another function, is then designed in such a way that said edge area by an annular matt and to Lens base surface is largely parallel edge zone of the lens holder is formed.
- a lens edge region provided in one piece on the edge side can be on Lens body be present which also serves to illuminate the surroundings and in addition contributes to the optical enlargement of the lens as such.
- an optically not active non-illuminated edge area by overdimensioning the Lens diameter is formed.
- the lens body is in terms of its Oversized diameter so far that it is still within the specified range Installation space fits in, so it does not necessarily have to be enlarged because the space used Diameter only has a focal length-related position.
- the optically not active The edge area therefore has no focal length reference.
- oversized lens but not illuminated over the full area so that the edge area not illuminated only the optical magnification of the Lens diameter and thus the headlight optics or headlight design. Residual light can also be emitted via said edge area, but this is not mandatory.
- the figures show headlights according to the invention in side view only with Presentation of the affected elements.
- Figure 1 shows a first embodiment of the invention in which behind a Headlight glass 20 around the actual projection lens 1 in a corresponding manner Alignment a circular ring element 2a is arranged.
- This circular ring element 2a largely parallel to the lens base surface and also optically corresponding coated or colored, so that this is an apparent enlargement of the Lens diameter and thus the design of the vehicle headlight.
- the ring element can be attached to the edge of the lens.
- a further conventional cover element 10 can be arranged in front of this.
- Figure 2 shows an embodiment of the invention in which the already existing Cover element 10 of the lens 1 in the area around the lens accordingly is largely parallel to the lens base surface, and also in shape an annular region 2b.
- a corresponding coating in the affected The circular ring area then ensures an optically enlarged diameter of the lens and so that an optically enlarged design would be necessary without the additional installation space, because the said elements are arranged in the headlights anyway.
- FIG. 3 shows a lens 1, which itself also has an annular contour 2c having.
- This circular and integrally molded edge molding 2c Projection lens 1 is used to illuminate the surroundings. That is, this edge area only the unfocused scattered light around the lens or from this area radiates out.
- Projection lenses of this type have in addition to the actual one Illumination function also the signal image function which results from the fact that the inner lens area forms the highly bundled projection light cone and the Illuminates a diffuse surface weakened in brightness at the outer edge area offers oncoming traffic a glare-free signal.
- lenses of this type naturally also result in a optical enlargement of the lens surface results, which also fulfills the stated purpose.
- FIG. 4 shows an illustration in which an oversized lens 1 is used becomes.
- the lens cut and the corresponding projection plane and Projection parameters of the reflector mirror are dimensioned to the lens so that only an inner part of the lens is used directly.
- the oversized Edge region 2d is only used for the optical enlargement of the Headlight designs. This design also increases the overall length or depth in Headlights not, because in this front area also larger lenses accordingly Have space available. The depth, on the other hand, is used to realize a better one Look bigger.
- the optics i.e. the cut of the lens in the core area used is on the the entire geometrical dimension is precisely measured.
