Abstract
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 element 16 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.
Claims11
A lighting assembly including:
- a leadframe stamped out of a metal sheet material, the leadframe comprising at least a first leadframe part and a second leadframe part having a separation between them, wherein:
- the first leadframe part comprises:
- a first flat portion;
- a first inclined section bent at a first edge;
- and
- a second inclined section bent at a second edge opposite the first edge, the first and the second inclined sections being longitudinally offset from each other;
- and
- the second leadframe part comprises:
- a second flat portion;
- a third inclined section bent at the first edge and located opposite the second inclined section of the first leadframe part;
- and
- a fourth inclined section bent at the second edge, the third and the fourth inclined sections being longitudinally offset from each other;
- a plurality of spaced LED elements fixed to the leadframe and bridging the first leadframe part and the second leadframe part, each of the plurality of spaced LED elements comprising a packaging with at least a first contact tab and a second contact tab wherein the first contact tab comprises a contact surface arranged on and connected to the first flat portion, and wherein the second contact tab comprises a contact surface arranged on and connected to the second flat portion;
- wherein the plurality of spaced LED elements forms the only electrical connection between said first leadframe part and said second leadframe part;
- wherein the plurality of spaced LED elements is disposed to emit light when operated;
- and
- wherein the first, the second, the third, and the fourth inclined sections form light direction sections including reflective surfaces arranged to reflect light emitted from the plurality of spaced LED elements.
