    • 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.
    • 本发明描述了一种生产特定混合色LED光源的方法,至少从一个芯片初级辐射发射的光的一部分通过在发光装置转换。 这是具有前侧(即,被hingewandt于辐射的侧)的发光转换材料的表面上的电接触被施加为薄层的芯片。 为了这个目的,在涂覆之前的前侧电触点被增加在所述的电接触表面施加导电材料。 该方法允许由色彩映射(IEC色度图)和发光转换材料的层变薄的控制是一个特定的颜色映射的一个特定的调整。 此外,该方法是特别适合用于同时生产的在晶片组件的多个相同的码片的数的发光二极管光源。
