    • 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.
    • 本发明描述了一种用于制造发光二极管(LED)光源的方法,特别地包括混合彩色LED,其中由芯片发射的主要辐射的至少一部分通过发光转换而变换。 所述芯片包括前表面(即面向辐射方向的一侧)电接触,其表面以薄层的形式施加发光转换材料。 在涂覆之前,通过将导电材料施加到电接触表面来提高前侧电接触。 该方法通过监视颜色坐标(IEC色度图)和稀释发光转换材料层来使选择性地调整特定色坐标。 此外,该方法特别适用于从晶片复合材料中的多个类似的芯片同时制造多个LED光源。
