Zusammenfassung:A color-mixing section R1 is constructed by allocating to each light-adjusting area one or more LEDs 311, . . . as primary light sources and color-mixing elements R1(411), . . . for guiding primary light from the LED 311, . . . to color-mix or homogenize the brightness. An available element R2 for receiving secondary light from the color-mixing elements to emit light covers the entire color-mixing elements. The LEDs 311, . . . and the color-mixing elements R1(411), . . . are not superposed onto each other.
