White LED light source

2002 
White LED light source, consisting of various LED dice, which are arranged on a circuit board together under a dome-shaped encapsulant, wherein the LEDs be operated by an external voltage or current supply, characterized in that at least two LEDs (1a, 1b) of different emission color based on GaN and at least two LEDs (1c, 1d) of different emission color are present on AlInGaP-based that the current flow through the LEDs (1a, 1b) or adjusted separately adjustable on AlInGaP-based and GaN-based and the current flow through the LEDs (1d 1c) that the GaN (1a, 1b) and the AlInGaP LEDs (1c, 1d) are connected in parallel to each other and the LEDs of a Type (1a, 1b or 1c, 1d) but different emission colors are connected in series.
