Abstract
A light fixture can include at least one light source, and at least one power supply that receives primary power, where the at least one power source generates final power using the primary power, where the at least one power supply delivers the final power to the at least one light source. The light fixture can also include a controller coupled to the at least one power supply, where the controller detects an adverse event, and where the controller controls the at least one power supply to provide the final power to the at least one light source during the adverse event.
Claims20
A light fixture, comprising:
- at least one light source;
- at least one power supply that receives primary power, wherein the at least one power supply generates final power using the primary power, wherein the at least one power supply delivers the final power to the at least one light source;
- a controller coupled to the at least one power supply, wherein the controller:
- detects a failure of at least one control component, wherein the at least one control component is used to help control operation of the light fixture;
- overrides, upon detecting the failure of the at least one control component, operational protocols involving the at least one control component that has failed;
- and
- controls, using the operational protocols that have been overridden, the at least one power supply to provide the final power to the at least one light source during the failure of the at least one control component.
A lighting system, comprising:
- a first light fixture, comprising:
- at least one first light source;
- and
- at least one first power supply that receives first primary power, wherein the at least one first power supply generates first final power using the first primary power, wherein the at least one first power supply delivers the first final power to the at least one first light source;
- and
- a controller coupled to the at least one first power supply, wherein the controller:
- detects a first failure of at least one first control component, wherein the at least one first control component is used to help control operation of the first light fixture;
- overrides, upon detecting the failure of the at least one first control component, operational protocols involving the at least one first control component that has failed;
- and
- controls, using the operational protocols that have been overridden, the at least one first power supply to provide the first final power to the at least one first light source during the first failure of the at least one first control component.
A controller for a light fixture, comprising:
- a control engine coupled to a power supply of the light fixture, wherein the controller is configured to:
- detect a failure of at least one control component, wherein the at least one control component is used to help control operation of the light fixture;
- override, upon detecting the failure of the at least one control component, operational protocols involving the at least one control component that has failed;
- and
- control, using the operational protocols that have been overridden, the power supply to provide final power to at least one first light source of the light fixture during the failure of the at least one control component.
