INTERFACE CAP DESIGN FOR LIGHT TUBES

Document Type and Number:

WIPO Patent Application WO/2017/139914

Kind Code:

A1

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.
