Abstract: A lighting fixture is provided including superimposed first and second printed circuit boards (PCBs), wherein LEDs on the first, top PCB are provided over a center cluster of LEDs on the second, bottom PCB in order to create a superimposed lighting effect. A processor controls a first group of LEDs on the first PCB independently of a second group of LEDs on the second PCB. A lighting effect is produced in which light from the first group of LEDs is superimposed over, and mixed with, light produced by the second group of LEDs.

Abstract: A controller is provided which comprises one or more processors, a control store, a first interface control unit for interfacing a local core and a second interface control unit for interfacing one or more remote cores via an interconnect, wherein the processor/s discloses programmable mini-processor/s is adapted to execute, add, remove or modify a function by executing micro-code maintained typically in the local memory but also possibly in remote, or even off-chip memory, and obtained via the control store, in response to receiving a command from the first or the second interface control unit.
