LED substrate with electrical connection by bridging

A support for one or more light sources for a lighting and/or light-signaling module for an automotive vehicle, comprising:

• a substrate made of heat-conducting material, preferably made of a metal material;
• at least one light source of light-emitting diode type with one face for mounting on the said substrate in thermal contact with the latter;
• and
• a circuit for controlling an electrical power supply of said one or more light sources, said circuit being printed on or in a board,
• wherein said circuit for controlling said electrical power supply is electrically connected to said one or more light sources by means of metal wires that are soldered to a surface of said circuit,
• wherein said circuit for controlling said electrical power supply is borne by said substrate and comprises an edge that is facing said one or more light sources,
• wherein said substrate comprises cooling fins,
• wherein the at least one light source of light-emitting diode type is mounted on a base made of a ceramic material,
• wherein said substrate includes two opposite faces, each of the two opposite faces bearing at least one of the light sources, the substrate includes an orifice that connects the two opposite faces and is positioned opposite the board,
• wherein an electrical connection between the one or more light sources on the face of the substrate opposite that on which the board is positioned and the circuit extends through the orifice, and
• wherein the board includes a portion that extends through the orifice, the portion including at least one electrical contact, one of the metal wires extends from the at least one electrical contact to said one or more light sources on said face of said substrate opposite that on which said board is positioned.
