Power splitter circuit for electrodeless lamp

摘要

A lamp assembly adapted to operate as one of a total number of lamp assemblies that are connected together in series and connected to a ballast. The lamp assembly comprises an electrodeless, closed-loop, tubular lamp envelope enclosing mercury vapor and a buffer gas, and a transformer core disposed around a portion of the lamp envelope. An input winding is disposed on the transformer core so that it has a particular number of turns, N input . An auxiliary winding is disposed on the transformer core so that it has a particular number of turns, N auxiliary . The auxiliary winding is adapted to connect to the ballast and to couple with the input winding. The ratio of the particular number of turns N input to the particular number of turns N auxiliary is substantially proportional to the total number of lamp assemblies that are adapted to operate in series together.
