Abstract
A lighting module of a motor vehicle signaling device includes a ceramic substrate having opposite first and second faces, and a plurality of selectively activatable light sources mounted on the first face of the ceramic substrate. Each of the first and second faces of the ceramic substrate are provided with at least a first and a second respective interconnection layer. The ceramic substrate comprises a plurality of through holes designed to interconnect the first interconnection layer to the second interconnection layer.
Claims19
A lighting module of a motor vehicle signaling device, comprising a convex ceramic substrate comprising opposing first and second faces, and a plurality of light sources that can be activated selectively, mounted on the first face of the ceramic substrate, each of the first and second faces of the ceramic substrate being provided with at least one first interconnection layer and at least one second interconnection layer, respectively, wherein the ceramic substrate comprises a plurality of through-holes arranged to interconnect the first interconnection layer and the second interconnection layer, the whole ceramic substrate has only one curvature, and the ceramic substrate has a thickness of between 100 μm and 200 μm and the curvature with a radius of curvature of between 90 mm and 500 mm.
A lighting module of a motor vehicle signaling device, comprising:
- a ceramic substrate having opposing first and second faces, each of the first and second faces of the ceramic substrate being provided with at least one first interconnection layer and at least one second interconnection layer, respectively, wherein the ceramic substrate comprises a plurality of through-holes arranged to interconnect the first interconnection layer and the second interconnection layer;
- a plurality of light sources mounted on the first face of the ceramic substrate, the light sources configured to be activated selectively;
- a connector configured to receive an instruction for controlling the light sources;
- a plurality of control devices arranged to selectively control the light sources on the basis of the instruction received by the connector;
- and
- a support member on which the ceramic substrate is mounted,
- wherein the support member is provided with a plurality of recesses arranged to accommodate the control devices, or
- the support member is fixed to the ceramic substrate such that edges of the ceramic substrate are left free.
A lighting module of a motor vehicle signaling device, comprising:
- a ceramic substrate having opposing first and second faces, each of the first and second faces of the ceramic substrate being provided with at least one first interconnection layer and at least one second interconnection layer, respectively, wherein the ceramic substrate comprises a plurality of through-holes arranged to interconnect the first interconnection layer and the second interconnection layer;
- and
- a plurality of light sources mounted on the first face of the ceramic substrate, the light sources configured to be activated selectively,
- wherein each of the light source is mounted directly on the first interconnection layer, and
- the first interconnection layer comprises a plurality of connection sub-layers incorporating a plurality of integrated microcircuits, each of the light sources being connected, via the first interconnection layer, to one of the integrated microcircuits.
