A) The components and organization of the RGB control unit used in Design 1; 1. 12 VDC power supply input bus, 2. voltage regulator array, one regulator to supply one color on five HEX arrays, 3. power resistor array, one for each color on 5 hex arrays, 4. output fan, 5. output bus, 6. potentiometer bus. B) The Design 1 arrays in operation, tuned to an environment without red (left) and without green (right) C) The components of the 36-element control unit; 1. power supply, 2. 12 VDC bus, 3,4,5, red, blue and green circuit boards, 6. on-off switch/breaker, 7. pulse-wave modulator, 8. cooling fan. D) A diagrammatical representation of the 36 HEX LED layout. The position of HEX arrays (green hexagons), wire pass-through holes (red circles), ventilation holes (blue circles), and the vertical heat sinks (black bars) are presented. The complete 36-element array (top; Panel E) and bottom (Panel F).
