First Claim
1. A system for changing between a plurality of colors of light via toggling a single switch, the system comprising:
- a power source electrically connected via a switch to a regulator;
a microcontroller electrically connected to the regulator to receive power from the power source, the microcontroller configured to respond to interruptions in voltage from the power source;
an input capacitor electrically connected via an internal power supply to the microcontroller, the input capacitor selected to maintain a supply of power from the internal power supply to the microcontroller for a predetermined time period comprising a time period greater than a time period of an interruption to the power source;
a plurality of light sources electrically connected to receive power via the regulator, each light source configured to generate a different color when energized;
wherein toggling of the switch causes the interruption of power from the power source, the microcontroller powered during the interruption and for the predetermined time period by the supply of power from the internal power supply; and
wherein the microcontroller detects the interruption of power via the power source and responsive to the detection the microcontroller energizes a light source of the plurality of light sources.

Abstract
A lighting arrangement includes a light fixture including a plurality of light sources wherein each light source is configured to generate a different color light when energized; and a circuit arrangement included in the light fixture and operatively interposed between the plurality of light sources and a source of electrical power. This circuit arrangement is responsive to brief interruptions in the supply of electrical power of less than a predetermined period to simultaneously de-energize all of the light sources for a full duration of the interruption and to subsequently toggle energization from one light source to the next and thereby produce different color light in response to the cessation of the brief interruption.
