Abstract:
The invention relates to a method for producing a light source provided with electroluminescent diodes, in particular mixed colour diodes. The inventive method consists in transforming at least one part of primary radiation emitted a chip by means of luminescence conversion. The inventive chip comprises a front electric contact (in terms of a surface oriented towards a radiation emission) and a luminescence conversion material applied thereto in the form of a thin film. Prior to coating, the front electric contact is made higher by the application of a conductive material to the surface thereof. The inventive method makes it possible to adjust in a target manner a defined chromatic localisation controlling said chromatic localisation (IEC chromaticity diagram) and reducing the layer of the luminescence conversion material. Said method is convenient, in particular for simultaneously producing several light sources provided with electrolumeniscent diodes from the plurality of similar chips in a section composite substrate.
