Abstract
An illumination system includes a plurality of distributed units, each having a light source and a light-source controller. The plurality of light sources simultaneously emits a selected type of light. The system also has a primary controller, which includes power-voltage-delivering circuitry and power-sequence-controlling circuitry. The power-voltage-delivering circuitry delivers a LOW or HIGH power voltage to the plurality of distributed units simultaneously. The power-sequence-controlling circuitry causes the power-voltage-delivering circuitry to automatically transition the power voltage between LOW and HIGH in different sequences corresponding to the type of selected light. Each of the plurality of light-source controllers is configured to detect the power voltage provided to the corresponding distributed unit and cause the corresponding light source to emit the selected light type upon receiving the corresponding sequence while the power voltage is HIGH and at a constant voltage.
