Publication number: 20230092612Abstract: 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.Type: ApplicationFiled: June 13, 2022Publication date: March 23, 2023Applicant: BWI Technology LLCInventors: Bruce R Roberts, Jeffrey Marc Nall, Steve McNay
