Claim 24:
25. A UVC germicidal illumination device, comprising:
a power source configured to supply input power to said UVC germicidal illumination device;
at least one UVC light source configured to generate ultraviolet light;
a first at least one power supply unit configured to provide output power to the at least one UVC light source;
a relay connected between said power source and said first at least one power supply unit;
at least one sensor that is in communication with the relay and configured to generate a sensor output signal responsive to a detection of a person or object by the at least one sensor;
wherein said relay is configured to receive the sensor output signal from the at least one sensor and disconnect the power source from the first at least one power supply unit in response to the received sensor output signal;
wherein said relay is further configured to re-connect the power source to said first at least one power supply unit when said sensor output signal is no longer being received by the relay; and wherein the UVC germicidal illumination device further comprises a second at least one power supply unit providing output power to at least one white color light source;
wherein said relay is triggered by said sensor output signal to turn on said second at least one power supply unit and at least one white color light source via the Normally Open output connection of said relay when said at least one sensor does detect a person or object is entering or already present in a room or space; and
wherein said relay is triggered by said sensor output signal to turn off said second at least one power supply unit and at least one white color light source via the Normally Open output connection of said relay when said at least one sensor does not detect a person or object entering or is already present in a room or space.
