Abstract: The invention describes an LED lighting assembly (1) comprising a reflector unit (11) comprising a number of reflector regions (11_lo, 11_hi); an LED carrier (10) realised to support at least one LED arrangement (2_lo, 2_hi); and at least one positioning feature (Ρ χ , Ρ γ , P Z ) for positioning the LED carrier (10) relative to the reflector unit (11), wherein a positioning feature (Ρ χ , Ρ γ , P Z ) is arranged in the same plane as the optical centre of the LED arrangement (2_lo, 2_hi). The invention further describes a method of manufacturing such an LED lighting assembly (1).

Abstract: A lighting system 60 and a method of operating a lighting module 10 are described. The lighting module 10 includes a heat sink 12. A first LED element 30a is mounted on the heat sink 12, disposed such that light emitted from the first LED element 30 in operation is emitted from the lighting system 60 as a low beam pattern 80a. A second LED element 30b is mounted on the heat sink 12, disposed such that light emitted from the second LED element 30b in operation is emitted from the lighting system 60 as a high beam pattern 80b. A driver circuit 84 is electrically connected to the first and second elements 30a, 30b to selectively supply electrical power for operation. The driver circuit 84 is disposed to operate in a first and a second mode. In the first mode, to provide a low beam illumination, the first LED element 30a is operated in a high power state while the second LED element is turned off. In the second mode, to provide a high beam illumination, the second LED element 30b is operated in a high power state, while the first LED element 30a is operated in a dimmed state.

Abstract: A lighting device (10) and a method of manufacturing a lighting device (10) are described. In order to allow high flexibility in manufacturing, the lighting device (10) comprises a heat sink (12) providing a first mounting area (22) for at least one LED element (24), a second mounting area (23) for at least one electrical connection assembly (36), a cavity (20) in the heat sink (12) adjacent to said first mounting area (22). An inner part (34) is arranged at least partially inside the cavity (20) comprising at least a first (26a, 28a) and a second connection terminal (26b, 28b) and at least one electrical connection path (44). The first (26a, 28a) and the second connection terminal (26b, 28b) are provided on a surface of the inner part (34). The first connection terminal (26a, 28a) is arranged between the first mounting area (22) and the second connection terminal (26b, 28b). The second connection terminal (26b, 28b) is arranged between the second mounting area (23) and the first connection terminal (26a, 28a). The electrical connection path (44) is provided at least partially inside the inner part (34) connecting the first (26a, 28a) and second electrical terminal (26b, 28b).

Abstract: A lighting module (10), a lighting system (60) with a lighting module (10), and a method of replacing a lighting module (10) in a lighting system (60) are described. The lighting module (10) comprises a heat sink (12) with a body portion (14) and a protrusion portion (16) protruding from the body portion (14) into a forward direction F. An LED element (30a) is mounted on a mounting surface (26a) of the protrusion portion (16). The mounting surface (26a) is arranged facing partially backwards and forming an angle of 5- 45° to the forward direction F. An electrical plug connector (40) is provided at the body portion (14). The LED element (30a), (30b) is electrically connected to the electrical plug connector (40) and the electrical plug connector (40) is provided within a cavity (42) of the body portion (14). In the lighting system, a reflector assembly (62) comprises a concave reflector with an inner reflector space (70). A lighting module (10) is arranged such that its protrusion portion (16) projects into the inner reflector space. Light emitted from the LED element (30a) is reflected by the reflector. The body portion (14) is arranged outside of the reflector space (70). The lighting module (10) may be replaced by separating the lighting module from the reflector assembly (62) and providing a new lighting module (10).
