  • Patent number: 10798794
    Abstract: The present invention discloses an LED lighting assembly configured to retrofit a fluorescent tube, comprising at least one LED, and a driving circuit configured to drive the at least one LED. The driving circuit comprises a switch control module and a rectifying circuit. The driving circuit is connected to the at least one LED and configured to receive and process an AC voltage signal from one side or both sides of the LED lighting assembly, and control the driving of the at least one LED based on the processed voltage signal. The rectifying circuit is connected to the at least one LED and configured to convert an AC power inputted to the rectifying circuit into a DC power supplied to the at least one LED. The present invention also discloses an LED driving circuit configured to retrofit a fluorescent tube.

  • Publication number: 20190137050
    Abstract: A new light apparatus (such as LED lamps) and lamp caps (30) for connecting the light apparatus to corresponding lighting fixtures for operation at higher voltages with existing lighting fixtures, by using modified caps (30) comprising groove/gap (32) patterns in the insulating materials of the caps (30). The new and/or improved lighting sources/light tubes operating at a higher voltage using the same interface caps (30) may require a larger minimum creepage distance between power coupling electrodes/pins (22a,22b). This can be accomplished by adding one or more grooves or gaps (32) of predefined dimensions in the electrically insulating materials on surface of cap (30) in a vicinity of the at least two conductive elements/electric pins (22a,22b). The light apparatus utilizing a same or a different lighting technology but operating at a higher operating voltage than the original/legacy light apparatus.
