摘要:
A lighting arrangement for use in automotive front lighting and a method of producing such an arrangement are described. At least one LED lighting element 40 is provided for emitting light. A collimator 10 is provided for forming an emission pattern of the emitted light, which is subsequently projected by a secondary optic arrangement 42. The collimator 10 comprises a cutoff reflector surface 18 with a front edge 30 and a back edge 32. The back edge 32 is located adjacent to the LED lighting element 40. The front edge is spaced from the back edge 32 in a depth direction X, A. The front edge 30 is arranged as a shielding edge for forming a light/dark cutoff in the emission pattern. First and second lateral reflector surfaces 26a, 26b are arranged opposite to each other adjacent to the LED lighting element 40. The front edge 30 of the cutoff reflector surface 18 is arranged within a focal area of the secondary optic arrangement 42. For providing a beam pattern well suited for automotive front lighting, the first and second lateral reflector surfaces 26a, 26b extend further into the depth direction A, X than the cutoff reflector surface 18.

A lighting assembly and a lamp for a motor vehicle are described. A leadframe 14 out of a metal sheet material comprises a first part 14c and a second part 14b not directly electrically connected. An LED element16 is fixed to the leadframe 14. A first contact part 24a is connected to the first leadframe part 14c and a second contact part 24b is connected to the second leadframe part 14b. The LED element 16 is disposed to emit light when operated. In order to achieve a desired directed emission of light in a simple way, the leadframe 14 comprises a light direction section 20a,20b including a reflective surface 30a,30b arrange to reflect the light emitted from the LED element 16.

A lighting unit (1) is provided with a reflecting surface (2, 2′, 2″) for providing an output beam of light with at least two beam patterns. A first light source (5) and a second light source (7) are arranged to illuminate substantially identical surface areas of said reflecting surface (2, 2′, 2″) and are independently controllable from each other. The reflecting surface (2, 2′, 2″) is shaped and said light sources (5, 7) are positioned relative to said reflecting surface (2, 2′, 2″) so that said first light source (5) generates an output beam of light, having a first beam pattern and said at least second light source (7) generates an output beam of light, having a second beam pattern, different from said first beam pattern. A corresponding vehicle headlamp (10) comprises at least one lighting unit (1).

A lighting device and a lighting unit comprising a reflector (52) and a lighting device, or LED lamp (10) are described. The LED lamp have a first and a second LED assembly (30, 32). Each LED assembly (30, 32) comprises at least one LED element (34a, 34b, 34c; 36a, 36b, 36c) with an LED chip (40) and a carrier (38) with a flat surface for carrying the LED chip (40). The LED chip (40) emits light with a main optical direction. The first and second LED assembly (30, 32) are mounted relative to each other so that at least a first LED element (34a) from the first LED assembly (30) and a second LED element (36a) from the second LED assembly (32) enclose a rotating angle (γ) between their respective flat surfaces with respect to an axis of rotation (A), so as to involve light angle between the first and second main optical directions. The axis of rotation (A) is parallel to a plane of a flat carrier surface of at least one LED element (36a). The first and second LED assemblies (30, 32) are arranged offset from each other parallel to the axis of rotation (A). Thus, a lighting device with small dimensions and advantageous light distribution is obtained.

The invention provides a car lighting unit (1) comprising a reflector (10) and a light source (20) arranged to generate light (21). The reflector (10) circumferentially surrounds the light source and the reflector has a reflector opening (11). The reflector is arranged to reflect at least part of the light from the light source through the reflector opening. The car lighting unit further comprises a 3D hologram (30). The car lighting unit is constructed to generate a beam of light (22) and a holographic 3D image (31), using light from the light source (20).
