Abstract: A new lighting fixture electronics design is disclosed that is particularly useful for lighting fixtures to utilize energy either directly from the traditional AC power grid or from locally generated renewable DC power sources. The invention entails improvement to the traditional LED driver or lighting ballast design to be able to additionally accept local DC microgrid power directly, without the need to pass the DC power through an external inverter to create an AC voltage. In this way, building construction can be commenced with a single lighting fixture that is capable to operate in multiple input modes, receiving power either from the AC grid or a DC grid, without the need for additional expense required to update the circuitry of the lighting fixtures in the building when the building is upfit at a future date with local renewable energy generating devices.

Abstract: A system and method obtaining image data of a light fixture having an indicator associated with the light fixture. The indicator at least partially attenuates light generated by one or more light generating devices disposed within the light fixture. The method also includes determining one or more characteristics of the indicator based on the image data that is obtained, and one or more of determining a unique identity of the light fixture based on the one or more characteristics of the indicator that are determined or determining a location of the light fixture within a structure based on the one or more characteristics of the indicator that are determined.
