ILLUMINATION SYSTEM WITH COLOR-CHANGING LIGHTS
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.
1 . An illumination system comprising:
a plurality of distributed units, wherein each of the plurality of distributed units comprise a light source and a light-source controller;
a primary controller including:
power-voltage-delivering circuitry configured to deliver a LOW or HIGH power voltage to the plurality of distributed units simultaneously; and
power-sequence-controlling circuitry configured to cause the power-voltage-delivering circuitry to automatically transition the power voltage between LOW and HIGH to encode a message; and
wherein, based on at least one difference between the plurality of light-source controllers:
a first subset of the plurality of light-source controllers causes a corresponding first subset of the plurality of light sources to emit a first type of light in response to the message and causes the corresponding first subset of the plurality of light sources to continue emitting the first type of light while the power voltage is HIGH and at a constant voltage; and
a second subset of the plurality of light-source controllers causes a corresponding second subset of the plurality of light sources to emit a second type of light upon receiving the message and causes the corresponding second subset of the plurality of light sources to continue emitting the second type of light while the power voltage is HIGH and at a constant voltage.
2 . The illumination system of claim 1 , wherein the at least one difference between the plurality of light-source controllers comprises at least one imperfection in the first subset of the plurality of light-source controllers and at least one imperfection in the second subset of the plurality of light-source controllers.
3 . The illumination system of claim 1 , wherein the at least one difference between the plurality of light-source controllers comprises each of the first subset of the plurality of light-source controllers being configured differently from each of the second subset of the plurality of light-source controllers.
4 . The illumination system of claim 1 , wherein:
the first type of light comprises a first effect;
the second type of light comprises second effect; and
the second effect is different from the first effect.
5 . The illumination system of claim 1 , wherein:
the first type of light comprises a first color;
the second type of light comprises second color; and
the second color is different from the first color.
