Abstract
A networked light control system includes light sensor circuitry that includes plural light sensors configured to sense an ambient light level, a control unit configured to generate a control signal that activates or deactivates one or more lights in a network of lights based on the ambient light level that is sensed by the light sensor circuitry, and relay logic circuitry configured to open or close a relay or a solid state switch for activating or deactivating the one or more lights based on receipt of the control signal generated by the control unit. The relay logic circuitry is configured to control the relay or the solid-state switch responsive to a failure in the control unit.
Claims20
A networked light control system comprising:
- light sensor circuitry that includes plural light sensors configured to sense an ambient light level;
- a control unit configured to generate a control signal that activates or deactivates one or more lights in a network of lights based on the ambient light level that is sensed by the light sensor circuitry;
- and
- relay logic circuitry configured to open or close a relay or a solid-state switch for activating or deactivating the one or more lights based on receipt of the control signal generated by the control unit,
- wherein the relay logic circuitry is configured to control the relay or the solid-state switch responsive to a failure in the control unit.
A method for controlling a networked light control system, the method comprising:
- sensing an ambient light level using light sensor circuitry that includes plural light sensors;
- generating a control signal using a control unit that activates or deactivates one or more lights in a network of lights based on the ambient light level that is sensed;
- opening or closing a relay or solid state switch using relay logic circuitry for activating or deactivating the one or more lights based on receipt of the control signal generated by the control unit;
- determining a failure in operation of the control unit;
- and
- transferring control of the relay or solid state switch to the relay logic circuitry responsive to determining the failure in the operation of the control unit.
A networked light control system comprising:
- light sensor circuitry including a first light sensor configured to sense an ambient light level;
- a control unit configured to activate or deactivate a light based on the ambient light level that is sensed by the first light sensor;
- and
- relay logic circuitry configured to open or close a relay or solid state switch for activating or deactivating the light based on the control signal generated by the control unit,
- wherein the relay logic circuitry is configured to control the relay or solid state switch responsive to a failure in the control unit.
