Embodiment Construction

[0041] said figure 1 with 2 A first embodiment of the invention is shown. figure 1 is a perspective view of the top surface of the support for light emitting diode type light sources. The support 2 mainly comprises a substrate 4 carrying light emitting diodes 12 . More specifically, the base plate, made of a thermally conductive material such as aluminium, comprises a thin and substantially flat first portion 8 and a second portion 6 forming cooling fins. The first and second parts are preferably integral, more preferably made from one piece of the same material. The fins 6 may extend in a direction substantially transverse, preferably perpendicular to the median plane of the first part.

[0042] The top surface 24 of the first part 8 carries two light-emitting diodes 12 . These are high power diodes, ie power greater than or equal to 3 watts, and the high power diodes can be fixed by their substrate. The diode comprises a substrate 20 made of ceramic material and an opt...

Abstract

The invention relates to a substrate (2) for one or more light sources for a lighting and / or luminous signalling module for a motor vehicle, comprising a substrate (4) made of a heat-conducting material, preferably made of metallic material; at least one light source (12) such as a light-emitting diode, with a surface for mounting on the substrate (4), in thermal contact with the latter; and a circuit for controlling the power supply (10) of the one or more light sources (12). The circuit for controlling the power supply is electrically connected to the one or more light sources by means of metal wires welded on the surface (16) by the technology commonly referred to as "wire / ribbon bonding". The invention also relates to a method for assembling such a substrate.

Description

technical field [0001] The invention relates to the field of lighting and / or light signaling, in particular for motor vehicles. More specifically, the invention relates to the field of mounting and electrical connection of light emitting diode (LED) type light sources. The invention relates to a support for one or more light sources, to a module comprising such a support and to a method for assembling said support. Background technique [0002] The use of light sources of the light emitting diode type in lighting and / or light signaling systems is increasingly widespread. In the field of automotive lighting and light signaling, diodes known as high-power diodes are used. High power diodes are generally generally planar and surface mounted. Surface-mounted components involve soldering components of a circuit board to its surface (SMD stands for "surface-mounted device"), rather than having pins pass through it. Since light-emitting diodes are semiconductors, they are affec...
