The projection lighting unit includes a light source device (2) e.g. LED luminous element chip, attached to a reflector device (3) and a lens (5) pre-located in the direction of the light beam of the reflector device. The reflector device is opened in a unique direction, and extends in a region between a plane of extension of the light source device and an optical axis (7) of the lens.

Description

The invention relates to a headlamp for vehicles having at least one projection light unit for generating a predetermined light distribution, wherein the projection light unit has a reflector device, a light source device associated with the reflector device and a lens located in the light exit direction of the reflector device.

From the DE 10 2004 047 301 A1 a projection headlight for vehicles is known, which has a first projection light unit for generating a first light distribution and a second projection light unit for generating a second light distribution. The first projection light unit has a first reflector device and a first light source device; the second projection light unit has a second reflector device and a second light source device. These devices of the first projection light unit and the second projection light unit are optically separated from each other. The first reflector device and the first light source device and the second reflector device and the second light source device, on the other hand, cooperate with an upstream diaphragm and a shared lens according to the projection principle, so that different light distributions associated with the projection light units can be generated. The first light source device and the second light source device are each arranged in a region close to an optical axis of the lens. The main emission direction of the first light source device and of the second light source device is perpendicular to the optical axis in the opposite direction outward in the direction of the respectively associated first reflector device and second reflector device. The first light source device and the second light source device are each arranged on a carrier which runs along the optical axis of the lens. A disadvantage of the known projection headlamp is that a plurality of identical first projection light units or second projection light units are required to produce a predetermined light function, such as a low-beam function.

Object of the present invention is to develop a headlight for vehicles such that a light unit is constructed to save a given light function efficient and space-saving.

To achieve this object, the invention in connection with the preamble of claim 1, characterized in that the reflector device (3) is designed to open exclusively in a single direction and that the reflector device (3) at least in a region between an extension plane of the light source device (2) and the optical axis (7) of the lens (5).

The particular advantage of the invention is that a light unit for generating a light unit, such as a low beam distribution or a motorway light distribution or a high beam distribution, can be designed extremely space-saving and effective. For this purpose, a reflector device is designed to be open only in a single direction, the opening of the reflector device being arranged on a side of the reflector device facing the light source device. If the opening of the reflector device is opened vertically upwards, a low-beam light distribution / motorway light distribution can be generated. If the opening of the reflector device is aligned vertically downwards, a high beam distribution can be generated.

The invention efficiently enables relatively high light intensities with very small light exit surfaces. In particular, a suitable drop in intensity in the overall light distribution can be easily realized.

According to a preferred embodiment of the invention, the headlight according to the invention is characterized in that differently configured light units generate different light distributions or partial light distributions, which form a predefined total light distribution by superposition. On the one hand, at least one projection light unit consisting of a light source device, a reflector device and a lens is provided, which has a predetermined light distribution, for example an asymmetrical light image with a 15 ° rise or a symmetrical light image, generated. The light distribution produced thereby has areas with relatively high illuminance levels and / or with large gradients of the illuminance levels. On the other hand, at least one reflector-free light unit is provided, which is formed only from a light source device and a lens. This at least one reflector-free light unit generates a relatively wide light distribution, which preferably acts in a relatively close road space area. These are direct imaging light units that require a relatively small amount of space. As a result of the superposition of light distributions according to the invention of the at least one projection light unit on the one hand and the at least one reflectorless light unit on the other hand, a predetermined total light distribution, for example for producing a low beam function, can be realized. The basic idea of the invention is to form an overall light distribution from a multiplicity of differently configured light distributions, whereby the light-technical characteristics of differently constructed light modules are made use of.

According to a particular embodiment of the invention, two projection light units are arranged one above the other in the vertical direction, with reflector surfaces emerging in the light exit direction leading to a common aperture. Characterized in that a first light source device and / or a second light source device are arranged at a relatively large distance from an optical axis, an improved dissipation of the resulting during operation of the light source means heat to a rear heat sink can be ensured. For example, the light source carriers may be solid without reducing the optically effective areas of the projection light units. This results in an improved thermal connection of the light source devices, which make it possible for the light source device to have a plurality of light sources for increasing the illuminance.

According to a preferred embodiment of the invention, a center axis of the first reflector device and a center axis of the second reflector device form an opening angle of at least 10 °. As a result, a maximum light output ensures that the light reflected from the respective associated reflector devices light is reflected freely in the direction of the lens.

According to a preferred embodiment of the invention, a diaphragm associated with a reflector is designed as an inclined surface, which is designed to increase in the direction of an apex region of the reflector with respect to an optical axis. In the apex area of the reflector, the inclined surface is connected via a curved boundary line with the reflector.

Advantageously, the embodiment according to the invention has an optimization of the light distribution in terms of range, ride comfort and safety. Further, aberrations of the projection lens can be suppressed and a tolerance sensitivity in the production of the headlamp can be reduced. This is effected in particular by the diaphragm edge formed according to the invention.

Further advantages of the invention will become apparent from the further subclaims.

Embodiments of the invention are explained below with reference to the drawings.

A headlamp for vehicles according to a first embodiment of the invention according to the FIGS. 1 a to 8 consists of a plurality of light units, the side by side and / or one above the other in a common headlight housing are arranged. The light units can serve to produce a low beam function.

A first light unit 1 is designed as a projection light unit and has a light source device 2, a reflector device 3 and a lens 5 arranged upstream in the light emission direction 4. The light source device 2 preferably has a plurality of LED lighting elements, which are embodied in a chip form. The reflector device 3 is open at the top and preferably has highly reflective and / or wholly or partially diffusely reflecting reflector surfaces 6, which are concave-shaped. The reflector device 3 has, in a distance close to an optical axis 7 of the lens 5 and remote from the light source device 2, reflector oblique surfaces 8 which slope down in the light emission direction 4 and extend at a relatively small acute angle of at least 10 °. The reflector oblique surfaces 8 have at least one curved surface, preferably curved partial surfaces 9, 9 '. The inclined surface 8 has an offset portion 10 which is bounded by edge-side fold lines 11. These crease lines 11 extend substantially parallel to the optical axis 7. The offset section 10 extends at an acute angle (15 °) to a horizontal plane and is responsible for ensuring that an asymmetric light distribution L1 with a 15 ° increase in brightness is achieved. Dark border according to Figure 1 b is produced. On one of the lens 5 facing the end of the reflector device 3, a blend edge 12 is formed, which forms a front outlet of the inclined surfaces 8. The upper in the vertical direction contour of the blend edge 12 corresponds to the free end of the inclined surface 8. The blend edge 12 thus has a plurality of kinks or bends in a plane perpendicular to the optical axis 7 level. How out FIG. 7 can be seen, the diaphragm edge 12 is substantially rectilinear, wherein the offset portion 10 is limited by kinks.

According to an embodiment of the invention, not shown, the headlamp for generating a low-beam distribution and / or motorway light distribution only a single light unit 1 according to FIG. 1 a or 2a, wherein the reflector device 3 is formed open in the vertical direction upwards. The opening the reflector device 3 is arranged oriented on one of the light source device 2 side facing and has an oval-shaped contour.

According to an alternative embodiment of the invention, not shown, the reflector device 3 may also have a recess open in the vertical direction downwards, that is, the reflector device 3 is open at the bottom. Here, the headlight is mirrored around a horizontal plane to the in FIG. 1 arranged light unit 1 arranged so that a predetermined high beam distribution can be generated.

In a horizontal plane, the blend edge 12 has a concave curvature, that is, ends 13 of the blend edge 12 are arranged in the light emission direction 4 in front of a center 14 of the blend edge 12. The blend edge 12 has an edge rounding with a diameter that is greater than 0.05 mm. Preferably, the headlight has four in FIG. 1 a shown projection light units. These each generate the light distribution L1 according to Figure 1 b having an asymmetrical light characteristic, wherein preferably a remote road space area is illuminated with a relatively high light intensity.

A second projection light unit 15 consists - like the projection light unit 1 according to FIG. 1a - Also from a light source device 16, a reflector device 17 and a lens 18. The light source device 16 is similar to the aforementioned projection light unit 1 and extends substantially above the reflector means 17. A major axis H1 of the light source means 16 extends - as in the projection light unit. 1 - perpendicular to the optical axis 7, see FIG. 6a , The orientation of the light source device 16 thus extends perpendicular to the optical axis 7, that is, in the vertical direction downwards.

The reflector device 17 is - like the reflector device 3 of the projection light unit 1 - arranged in the vertical direction above the optical axis 7 of the lens 18.

The same components or component functions are provided with the same reference numerals.

In contrast to the first projection light unit 1, the second projection light unit 15 has a continuously extending oblique surface 19. It follows that even a diaphragm edge 20 without a kink runs steadily. In the present embodiment, the diaphragm edge 20 is slightly curved in the vertical direction upwards. This results in a symmetrical light distribution L2 according to FIG. 2b which produces substantially a light distribution with a relatively high light intensity in a remote road space area. Preferably, the headlight has two second projection light units 15.

A third light unit 21 is designed as a reflector-free light unit and has only one light source device 22 and one lens 23. The lens 23 is arranged in the light emission direction 4 in front of the light source device 22, which may be formed from a plurality of LED chips. The light source device 22 is arranged substantially below the optical axis 7 of the lens 23 and has such an orientation that a light distribution L3 according to FIG FIG. 3b is produced. A major axis H2 of the light source device 22 forms an acute angle α with respect to the optical axis 7. The third light unit 21 essentially serves for the relatively wide illumination of a relatively close road space area, such as FIG. 3b can be seen.

A fourth type of light unit according to FIG. 4a is also formed as a reflectorless light unit 24, which also has the light source device 22 and the lens 23. In contrast to the third light unit 21, the light source device 22 is arranged in the region of the optical axis 7 or somewhat in the vertical direction above the optical axis 7. As a result, a light distribution L4 according to FIG. 4b produced with an improved width illumination, in particular a near road space area. The third light unit 21 and the fourth light unit 24 are each arranged in a threefold number in the headlight.

By superposing the light distributions L1, L2, L3, L4 of the light units 1, 15, 21, 24, a total light distribution GL according to FIG FIG. 5 generated, which meets the requirements of a given low-beam distribution.

In order to change light intensities or illuminance levels within the overall light distribution GL, the reflector device 3, 17 may be arranged to be displaceable and / or pivotable at a distance from the lens 4. In addition, to change the total light distribution GL, the light source device 2, 16, 22 can be adjustable in their light intensity. For example, individual LED chips of the light source device 2, 16, 22 can be switched off or switched on.

In the Figures 6a, 6b, 6c For example, light rays generated by the first projection light unit 1 are shown. According to FIG. 6a a boundary beam 25 is shown, which, while limiting the diaphragm edge 12, strikes a light incident surface 26 of the lens 5 directly. In FIG. 6b is a light beam dargstellt 27 which reflects a single time on the reflector surface 6 of the reflector device 3 and strikes the light incident surface 26 of the lens 5 while limiting the diaphragm edge 12. In FIG. 6c a light beam 28 is shown, which is reflected on the reflector surface 6 of the reflector device 3 and on the other hand on the inclined surface 8 of the reflector device 3.

The in the FIGS. 1 a . 2a . 3a, 4a illustrated light units 1, 15, 21, 24 can in a housing of the headlight, for example in a row 29 according to FIG. 9a be arranged.

Alternatively, these light units 1, 15, 21, 24 can also be stepped in an arrangement 30 having two rows arranged offset in the vertical direction in the vertical direction FIG. 9b be positioned.

According to a further embodiment according to FIG. 9c For example, the light units 1, 15, 21, 24 may also be positioned corresponding to an alternating arrangement 31, wherein the light units 1, 15, 21, 24 are alternately arranged in an upper horizontal plane and a lower horizontal plane.

According to a further embodiment according to FIG. 9d For example, the light units 1, 15, 21, 24 can also be combined in a trapezoidal or V-shaped arrangement 32, wherein the light units 1 extend in a plurality of horizontal planes. The light units 1, 15, 21 and 24 may each be grouped in the assemblies 29, 30, 31, 32 or alternately arranged.

According to a further embodiment of the invention according to the FIGS. 10 to 12 a projection light unit 30 may be provided, which differs from the first projection light unit 1 in that it additionally has a diaphragm 33 at a distance in the direction of the light emission direction 4 in front of the reflector surfaces 6. The diaphragm 33 is arranged above the inclined surfaces 8 and reduces the illuminance in a relatively close area of the road space. In FIG. 10 is an overall light distribution GL ', which is realized with the formation of modified projection light units 1, 15 with the diaphragm 33 and light units 21 and 24. In a central area Z of the total light distribution GL ', which is located at a distance below the cut-off of the total light distribution GL', the effective amount of light can be reduced, so that legal regulations with regard to the illuminance are met. Advantageously, the effectiveness of the light distribution GL 'can thereby be improved, since a relatively high light intensity is made possible in a road space area which is arranged remotely to the vehicle. In addition, the headlamp is tolerances insensitive to placement accuracy of the components of the headlamp to each other.

In FIG. 12 On the left side, the light distribution L1 of the projection light unit 1 and on the right side the light distribution L5 of the projection light unit 30 are shown. It can be seen that the illuminance in a vehicle-near region of the road space is reduced in an embodiment of the projection light unit with diaphragm 33.

According to a further embodiment of the invention according to the FIGS. 13 to 15 In contrast to the previous embodiment, a different reflector and diaphragm arrangement is provided.

The headlamp consists of a pair of reflector devices, which converge to a common aperture edge. The headlight has a first reflector device 100 which is arranged above an optical axis 140 and which is assigned to two light sources 70 (light-emitting diodes) for generating a low-beam light distribution. For this purpose, the upper reflector device 100 has two adjacently arranged reflectors 105, 105 ', to each of which a light source 70 is assigned.

Below the optical axis 140, a second reflector device 101 is arranged, which is associated with a further light source 70 (light emitting diode) for generating a high beam distribution. The second reflector device 101 has a single reflector 108 to which the light-emitting diode 70 is assigned. The light-emitting diodes 70 are - as in the preceding embodiments - respectively arranged on a side facing away from the optical axis 140 of the reflectors 105, 105 'and the reflector 108.

The first reflector device 100 and the second reflector device 101 are integrally connected to one another, wherein a arranged on a mutually facing side first aperture 106 of the first reflectors 105, 105 'with a second aperture 109 of the second reflector 108 converge to a common aperture edge 117. According to an alternative embodiment not shown, the first reflector device 100 and the second reflector device 101 may also be arranged physically separated from one another.

The first aperture 106 and the second aperture 109 each extend as an inclined surface to form an acute angle with respect to a horizontal plane E, in which the optical axis 140 extends. Starting from the common diaphragm edge 117, the distance B of the first diaphragm 106 increases toward the second diaphragm 109 in the direction of the apex region of the reflector devices 100, 101, as shown in FIG FIG. 10 is apparent. In the apex region of the reflector devices 100 and 101, the first diaphragm 106 and the second diaphragm 109 pass over a curved boundary line 120 or 121 into the first reflector 105, 105 'and the second reflector 108, respectively. According to an alternative embodiment, not shown, the first diaphragm 106 and / or the second diaphragm 109 can also pass continuously into the first reflector 105, 105 'or the second reflector 108.

The oblique surfaces of the first panel 106 and the second panel 109 are uneven and have at least one curved surface. The curvature surface may, for example, be formed as a curved subarea 126, 127 with at least one curvature line running transversely and / or in the direction of the optical axis 140. In a horizontally viewed in the middle region of the first aperture 106 and the second aperture 109, a bend 120 or a kink line is provided, which extends at an acute angle to the optical axis 140.

The diaphragm edge 117 does not run in a straight line but has formations in the horizontal (Z-direction) and vertical (Y-direction) directions. The diaphragm edge 117 has an offset portion 124 in which the diaphragm edge 117 extends in a straight line between a horizontal plane E contained in the optical axis 140 and a horizontal plane E 'parallel thereto, which is arranged below the optical axis 140 in the vertical direction. The rectilinear offset portion 124 forms an acute angle to the horizontal plane E.

The diaphragm edge 117 has an edge rounding with a diameter of at least 0.05 mm.

Advantageously, this embodiment of the invention enables an optimization of the light distribution in terms of range, ride comfort and safety. Image defects of the projection lens 102 can be suppressed.

According to an alternative embodiment of the invention, not shown, the first panel 106 and / or the second panel 109 may also be formed as a substantially flat sheet metal plate, at the free end, the panel edge 117 extends. Preferably, the metal plate extends horizontally.
