Yeah, thanks for that Link!
So I'll have to use expansion 3. Based on 2 RGB Channels, I need 6 PWM outputs.
The 1.5.7 Electronic has an LEDs output Pin. How much Power does it support?
I messured 18,8V. That would be perfect for the Dioder (with a step-down Board)
The Wiki says: "A PWM output with power for LED arrays and other lighting"
What is the exact current?
Thanks!

Lots of pins are used, but even more are free. But what's even easier to use for this, is the 2nd heater output. This heater output is PWM enabled, can be used with "M42 P4 S[pwm_value]" (For heater 2)
You should check the PCB layout for details which pins go where http://reprap.org/wiki/Ultimaker's_v1.5.7_PCB
