- US Pat. No. 7,484,872 B2 discloses a projection headlight for vehicles which has a light source device, a reflector device, a diaphragm and a lens arranged in front of it for generating a predetermined light distribution.
- the light source device is arranged in the vicinity of an optical axis of the lens, wherein a central axis of the light source device is arranged at an acute angle inclined to the optical axis, so that an improved alignment with the reflector surfaces of the reflector device are given.
- a disadvantage of the known projection headlight that it is at the horizontal aperture to unwanted reflections can occur, which cause a leading past the lens stray light.
- a projection headlight for vehicles which has an upper projection light unit with a first reflector device and a first shutter and a lower projection light unit with a second reflector device and a second shutter.
- the first diaphragm and the second diaphragm converge to form a common diaphragm tip, which has a front diaphragm edge for imaging the light / dark boundary.
- the first and the second aperture may each be formed as a metal plate.
- a projection headlight for vehicles with a first projection light unit for generating a first light distribution and with a second projection light unit for generating a second light distribution wherein the first projection light unit and the second projection light unit are arranged on both sides of a central plane which extends an optical axis of the two projection light units associated with the common lens.
- the first projection light unit and the second projection light unit each have a light source device, a reflector device and a diaphragm.
- the diaphragms are each arranged in the region of a rear focal point of the lens, with the two diaphragms converging in the main emission direction of the headlight to form a common diaphragm tip.
- the diaphragm tip or a front edge of the diaphragm tip extends in a central plane in which the optical axis of the lens is arranged. It has been shown that, due to the dimensioning of the components of the projection headlamp, a non-precise imaging of the light distribution at a front edge of the diaphragm tip can occur. Sometimes a part of the reflected light on reflector surfaces is again reflected at the diaphragm tip, resulting in an undesirable scattered light.
- Object of the present invention is therefore to provide a projection headlamp for vehicles with projection light units, in which light source devices a have greater or equal distance to an optical axis of a lens as Re ⁇ flektor anatomy, such further that easily predefined light distributions can be better represented or generated.
- the invention in conjunction with the preamble of claim 1, characterized in that the aperture tip protrudes at an acute angle from the central plane.
- the particular advantage of the invention is that an inclined diaphragm is present through a diaphragm tip arranged at a distance from an optical axis of a lens, so that a reduced imaging of the diaphragm edge takes place with respect to a first projection light unit to whose side the diaphragm tip is inclined opposite second projection light unit of unwanted scattered light generation is counteracted.
- the diaphragm edge is thus located at a greater distance from a focal point or a focal plane. While the sharpness of the image in the center is thereby relatively little affected, it decreases more towards larger angles.
- the inclination of the diaphragm tip allows light reflected in the second projection light unit not to be reflected again at the diaphragm tip, which would lead to an undesired scattered light. Instead, the reflected light beam is guided in the direction of the lens at the diaphragm tip.
- the diaphragm tip is rectilinear or arcuate, wherein they at least one transverse bending line extending transversely to the optical axis or to a central plane curved bend line with a Blendenansatzteil and / or tapering in Hauptabstrahlraum reflector surfaces of the first projection light unit and the second projection tion light unit is connected.
- a light guide body which is arranged substantially between two opposite light source devices of the first projection light unit and the second projection light unit.
- the projection headlamp thus has a compact and space-saving design for generating at least two light functions, such as dipped beam and main beam.
- the first light source means of the first projection light unit and the second light source means of the second projection light unit on a number of light sources, the central axis extending at an acute angle to the optical axis of the lens and / or at an acute angle opposite to the main emission are aligned with the corresponding reflector surface of the first reflector device or the second reflector device.
- the light flux detected by the reflector surfaces can thereby be increased.
- unwanted or uncontrollable stray light can be reduced.
- a diaphragm tip is positively and / or non-positively connected to a diaphragm attachment part of the diaphragm or a reflector surface, so that a precise positioning of a front edge of the diaphragm relative to the reflector devices and thus optimum light distribution is achieved.
- tolerance deviations can be compensated, so that a subsequent adjustment is no longer required.
- FIG. 3 a shows a schematic vertical section through a projection headlamp with a horizontal diaphragm tip (prior art), a schematic vertical section through the projection headlamp according to the invention with a diaphragm tip inclined with respect to a horizontal plane,
- 4b is a partial section of a high beam distribution with the projection headlamp according to the invention.

- Projection headlamp with an attached front panel seen from the front,
- FIG. 5b shows a side view of the arrangement according to FIG. 5a
- FIG. 5c shows a front view of the arrangement according to FIG. 5a
- FIG. 5d shows a vertical section along the line IV-IV in FIG. 5c and FIG
- FIG. 5e is a detail view X in Figure 5d.
- a projection headlight 1 for vehicles consists of a first projection light unit 2 for generating a low beam distribution and a second projection light unit 3 for generating a high beam distribution.
- the first projection light unit 2 and the second projection light unit 3 are for this purpose mounted in a common housing, which is covered by a crystal-clear cover in the main emission direction 4 of the projection headlamp 1.
- the first projection light unit 2 has a first light source device 5, a first reflector device 6 and a first diaphragm 7.
- the second projection light unit 3 has a second light source device 8, a second reflector device 9 and a second diaphragm 10.
- the first projection light unit 2 and the second projection light unit 3 are associated with a common lens 11, which is arranged in the main emission direction 4 in front of the first projection light unit 2 and the second projection light unit 3.
- An optical axis 12 of the lens 1 1 intersects a central plane or horizontal plane H of the first projection light unit 2 and the second projection light unit 3, which also forms a center plane of the projection headlamp 1.
- the lens 1 1 is thus part of one of the first projection light unit 2 and the other of the second projection light unit. 3
- One of the first projection light unit 2 and the second projection light unit 3 facing plane light entrance surface of the lens 1 1 detects on the one generated by the first light source device 5 first light beam L1, so that a first light distribution is generated. Furthermore, the plane light-engaging surface of the lens 11 detects a second light beam L2 generated by the second light source device 8, so that a second light distribution is generated.
- the first projection light unit 2 is used to generate a low-beam light distribution, wherein only the first light source device 5 is turned on. To generate a high beam distribution, the second light source device 8 is connected, so that superimposing the first light distribution and the second light distribution produces a Femlichtver notorious.
- the first light distribution and the second light distribution are generated in each case according to the projection principle, the first aperture 7 upstream of the first reflector device 6 and the second aperture 10 upstream of the second reflector device 9 being an image of a front edge 13 of the first aperture 7 or second aperture 10 effect.
- the front edge 13 at the same time forms an arcuate contour of a common aperture tip 14 of the first panel 7 and the second panel 10, wherein adjoins the Blendenspitze 14 opposite the Hauptabstrahlutter 4 a Blendenansatzteil 15, as part of the first panel 7 and the second panel 10th is connected to the first reflector means 6 and the second reflector means 9.
- the first light source device 5 is formed by three light-emitting diode chips 16 arranged offset in the horizontal direction, to each of which a reflector surface 17 of the first reflector device 6 is assigned.
- the second light source device 8 likewise has three LED chips 16, to each of which a reflector surface 18 of the second reflector device 9 is assigned.
- the LED chips 16 are arranged inclined or oriented obliquely backwards to the corresponding reflector surfaces 17, 18 of the first reflector device 6 or the second reflector device 9.
- a central axis M1 of the first light source device 5 includes, for example, an acute angle ⁇ 1 with the optical axis 12 of the lens 11, while a center axis M2 of the second light source device 8 encloses an acute angle ⁇ 2 with the optical axis 12 of the lens 11.
- the main emission direction of the luminous elements 16 of the first light source device 5 and the second light source device 8 thus depends on the proximity of a center of the calculated reflector surfaces 17, 18 of the first reflector device 6 and the second reflector device 9.
- second light source device 8 generated higher luminous flux component are detected.
- the intensity maximum of the first light source device 5 or second light source device 8 is directed into a better controlled region of the reflector surfaces 17, 18.
- the reflector surfaces 17, 18 of the first reflector device 6 and the second reflector ⁇ gate device 9 taper in Hauptabstrahlraum 4 until they pass into the first aperture 7 and second aperture 10.
- the distance of the opposing reflector surfaces 17, 18 of the first reflector device 6 or reflector device 9 thus decreases in the main emission direction 4 until it has reached its minimum level of the aperture 7, 10.
- the first panel 7 and the second panel 10 thus form an extension of the reflector surfaces 17, 18 and is preferably light-reflecting, that is formed mirror-like.
- the first diaphragm 7 and the second diaphragm 10 may also be designed to be light-absorbing.
- the first diaphragm 7 the upper surface contour of the diaphragm is preferably considered, and the second diaphragm 10 is preferably the lower surface contour of the diaphragm.
- the preferably flat formed aperture 14 includes with the horizontal plane H an acute angle ⁇ , which may for example be in a range between 5 and 20 °, preferably 10 °.
- the diaphragm tip 14 is raised with respect to the horizontal plane H in the direction of a side, in which the first projection light unit 2 is located, wherein at least one preferably straight crease line 19 is formed, which extends in the horizontal direction.
- gusset 20 of the diaphragm tip 14 are formed kinked, while a central region in which there is a 15 ° rise of the first panel 7, no kinked panel tip.
- the front edge 13 is arranged to extend in an arcuate manner in the horizontal direction, wherein the end regions of the front edge 13 each delimit the gussets 20.
- the diaphragm tip 14 is arranged inclined upward such that the light beam L2 generated by the second light source device 8 is reflected only by a single reflection on the reflector surfaces 8 of the second reflector device 6 in the direction of the lens 1 1 without a part of the light beam L2 striking the diaphragm tip 14. If the projection headlight 1 had a horizontal diaphragm tip 21, as is known from the prior art, a part of the light beam L2 would impinge on the horizontal diaphragm tip 21 and be reflected by this into a lower region of the lens 11, so that a scattered light radiation would be generated at an angle of ⁇ .
- FIGS. 3a and 3b Identical components or component functions in FIGS. 3a and 3b are provided with the same reference numerals.
- FIGS. 4a and 4b show the light distributions corresponding to FIGS. 3a and 3b, respectively, as they result on a measuring screen 10 m away. It can be seen that in order to use the horizontal diaphragm tip 21 according to FIG. 3a, the front edge 13 of the diaphragm tip 21 runs close to the imaginary focal plane of the lens 11. Thus, the front edge 13 of the aperture tip 21 is sharply imaged. This causes a relatively dark band in the high beam distribution, which can be seen in the region B1 of FIG. 4a by distortions of the isolines. Due to the inclined diaphragm tip 14 according to the invention, the front edge 13 is arranged at a distance from the focal plane.
- the image sharpness in the center is relatively little affected, while the same decreases more towards larger angles.
- the transition between the two light distributions, namely the low beam distribution and the high beam distribution can thus be made more homogeneous, as can be seen from the area B2 in Figure 4b.
- the first diaphragm 7 has a surface or contour, so that a predetermined low-beam light distribution is generated with a 15 ° increase.
- the first panel 7 has corresponding bending lines 22.
- the reflector surfaces 17, 18 may be formed ellipsoidal and / or paraboloidal, with their axis would be in the direction of the optical axis 12 of the lens 1 1 is arranged rotated.

- the reflector surfaces 17, 18 or hyperbolic may bebil ⁇ det as free-form surfaces.
- the LED chips 16 may have one or more LEDs.
- the LED chips can be designed to be dimmable and / or individually controllable.
- the dimming can be carried out by relation of the voltage and / or the current and / or by plus-time modulation.
