Principal Lighting Group Expands Global Patent Portfolio

Three patents give the company the right to license until 2030.




Principal Lighting Group (San Angelo, TX) announced the addition of three patents relating to LED assemblies designed for use with existing light support structures, such as those originally designed for fluorescent lamps. US Patent No. 9,851,054 relates to Principal’s market-leading Stik™ family of “direct-connect” retrofit assemblies. Principal’s Stik™ products represent a solution for outfitting T-12 fluorescent sockets with LED lamps in commercial signs.

Principal has also acquired U.S. Patent No. 9,311,835 and Canadian Patent No. 2,759,366, which relate to retrofit assemblies and methods that employ end caps between the extruded support module and the existing socket.

Principal’s retrofit patents give Principal the right to license its technologies or prohibit others from making, selling, using or importing infringing products and processes through 2030 and beyond.
