Abstract

A system for electrically connecting at least one light source to a system for supplying electrical power, wherein the connecting system comprises:
a lead frame able to be electrically connected to a system for supplying electrical power, the lead frame including at least one connecting terminal and at least one connecting means allowing the connecting terminal of the lead frame to be electrically connected to the light source,

the connecting terminal and the connecting means being able to electrically connect the light source to the lead frame, thereby allowing the light source to be placed away from the lead frame.

First claim

1 . A system for electrically connecting at least one light source to a system for supplying electrical power,
wherein said connecting system comprises:
a lead frame able to be electrically connected to said system for supplying electrical power, said lead frame including at least one connecting terminal; and
at least one connecting means allowing said at least one connecting terminal of said lead frame to be electrically connected to said at least one light source;
said at least one connecting terminal and said at least one connecting means being able to electrically connect said at least one light source to said lead frame, thereby allowing said at least one light source to be placed away from said lead frame.

2 . The system as claimed in claim 1 , wherein said lead frame includes a first means for dissipating heat allowing the heat generated by said lead frame to be dissipated.

3 . The system as claimed in claim 2 , wherein said first means for dissipating heat is a resistive circuit.

4 . The system as claimed in claim 1 , wherein said lead frame includes a converter allowing the, especially AC, voltage of the current delivered by said system for supplying electrical power to be converted into an, especially DC, voltage applied to said at least one connecting terminal of said lead frame.

5 . The system as claimed in claim 1 , wherein said lead frame includes a control circuit that controls said voltage of said current applied to said at least one connecting terminal.

6 . The system as claimed in claim 1 , wherein said at least one connecting terminal of said lead frame is a connecting pad able to allow said at least one light source to be connected by application of the wire bonding technique.

7 . The system as claimed in claim 1 , wherein said at least one connecting means is an electrically conductive wire.

7 . The system as claimed in claim 1 , where said lead frame comprises a printed circuit board to which electronic components may be connected.

9 . The system as claimed in claim 8 , wherein said lead frame comprises a border extending perpendicularly from said printed circuit board, said border including:
two substantially parallel longitudinal walls; and two substantially parallel transverse walls, which each connect said two longitudinal walls.

10 . The system as claimed in claim 9 , wherein said border and said printed circuit board define a seal-tight tray, said tray being filled with a liquefied plastic product.

11 . The system as claimed in claim 8 , wherein one of said longitudinal walls of said border comprises a recess in which said at least one connecting terminal is placed.

12 . The system as claimed in claim 8 , wherein one of said transverse walls of said border comprises on its external face a protruding housing the walls of which extend substantially perpendicular to said transverse wall, said lead frame including at least one electrical connector placed in said housing, said at least one electrical connector allowing said lead frame to be connected to said system for supplying electrical power.

13 . A light-emitting assembly, wherein said assembly comprises:
a system for electrically connecting said at least one light source to said system for supplying electrical power according to claim 1 ; said at least one light source; and a second means for dissipating heat allowing the heat generated by said at least one light source to be dissipated, said second means for dissipating heat being disconnected from said lead frame.

14 . The assembly as claimed in claim 13 , wherein said at least one light source is a light-emitting diode.

15 . The assembly as claimed in claim 13 , wherein said second means for dissipating heat is a holder of said at least one light source.

16 . A lighting and/or signaling device for an automotive vehicle, wherein said device includes said light-emitting assembly according to claim 13 .

17 . The system as claimed in claim 2 , wherein said lead frame includes a converter allowing the, especially AC, voltage of the current delivered by said system for supplying electrical power to be converted into an, especially DC, voltage applied to said at least one connecting terminal of said lead frame.

18 . The system as claimed in claim 3 , wherein said lead frame includes a converter allowing the, especially AC, voltage of the current delivered by said system for supplying electrical power to be converted into an, especially DC, voltage applied to said at least one connecting terminal of said lead frame.

19 . The system as claimed in claim 2 , wherein said lead frame includes a control circuit that controls said voltage of said current applied to said at least one connecting terminal.

20 . The system as claimed in claim 3 , wherein said lead frame includes a control circuit that controls said voltage of said current applied to said at least one connecting terminal.
