More Information
Summary:An LED support for at least two groups R, G, B, M of semiconductor light sources r, g, b, m connected in series is provided with conductor tracks which allow series connections of the semiconductor light sources of each of the groups. Said series connections together with connected voltage or current sources form independent loops which are arranged on the LED support in a non-planar line pattern. This allows the arrangement of the semiconductor light sources on rings which are concentric to one another, wherein at least two of said rings contain semiconductor light sources which belong to at least two of the different groups. A constant brightness and light distribution is achieved over the surface of the LED light source. Necessary line bridges are formed by bonded wire bridges which directly adjoin the LED chips and bridge a line leading to a chip bonding surface.
