The device is specifically employed in a lighting device for a motor vehicle, and permits the arrangement of light sources remotely from the connecting element which, in turn, can be arranged remotely from an electric power supply device of the light sources. The connecting device permits a high degree of freedom in the arrangement of light sources in relation to the device, as it casts little shadow upon the light sources, whilst ensuring the effective dissipation of heat generated thereby. ## Claims ### Claim 1 A device for the electrical connection of at least one light source to an electric power supply device, wherein the connecting device comprises a lead frame, first connecting means which are designed for the connection of the frame, by bridging, to a light source which is remote from the frame, and characterized in that the connecting device moreover comprises second connecting means which are designed to connect the frame, by crimping, to an electric power supply device. ### Claim 2 (depends on 1) The device according to claim 1, wherein the device comprises mechanical connecting means, which are designed to connect the device to heat dissipation means. ### Claim 3 (depends on 2) The device according to claim 2, wherein the mechanical connecting means project from a first surface of a support element, wherein the lead frame is accommodated on a second surface (154) of the support element, which is situated on the opposite side to the first surface. ### Claim 4 (depends on 2) The device according to claim 2, wherein the mechanical connecting means comprise a thermally conductive material. ### Claim 5 (depends on 1) The device according to claim 1, wherein the second connecting means comprise at least one electrically-conductive lug, which is designed to be crimped to a connecting element of an electric power supply device. ### Claim 6 (depends on 5) The device according to claim 5, wherein the second connecting means comprise a row of a plurality of electrically conductive lugs, separated by electrically insulating elements. ### Claim 7 (depends on 1) The device according to claim 1, wherein the first connecting means comprise at least one connecting pad and at least one bridging wire (124). ### Claim 8 (depends on 7) The device according to claim 7, wherein the bridging wire is connected to the connecting pad by welding. ### Claim 9 (depends on 1) The device according to claim 1, wherein the lead frame comprises an electric circuit. ### Claim 10 (depends on 1) A lighting device for a motor vehicle comprising electric power supply means which are connected by means of an electrical connecting element to at least one light source which is remote from the connecting element, wherein the connecting element is compliant with the device as according to claim 1. ### Claim 11 (depends on 10) The device according to claim 10, wherein the light source is a light-emitting diode, or LED. ### Claim 12 (depends on 10) A lighting and/or signaling device for a motor vehicle, wherein the device comprises a lighting device according to claim 10. ### Claim 13 (depends on 3) The device according to claim 3, wherein the mechanical connecting means comprise a thermally conductive material. ### Claim 14 (depends on 2) The device according to claim 2, wherein the second connecting means comprise at least one electrically-conductive lug, which is designed to be crimped to a connecting element of an electric power supply device. ### Claim 15 (depends on 3) The device according to claim 3, wherein the second connecting means comprise at least one electrically-conductive lug, which is designed to be crimped to a connecting element of an electric power supply device. ### Claim 16 (depends on 2) The device according to claim 2, wherein the first connecting means comprise at least one connecting pad and at least one bridging wire. ### Claim 17 (depends on 3) The device according to claim 3, wherein the first connecting means comprise at least one connecting pad and at least one bridging wire. ### Claim 18 (depends on 2) The device according to claim 2, wherein the lead frame comprises an electric circuit. ### Claim 19 (depends on 2) A lighting device for a motor vehicle comprising electric power supply means which are connected by means of an electrical connecting element to at least one light source which is remote from the connecting element, wherein the connecting element is compliant with the device according to claim 2. ### Claim 20 (depends on 11) A lighting and/or signaling device for a motor vehicle, wherein the device comprises a lighting device according to claim 11.
