ABSTRACT:
An improved plastic base for annular fluorescent lamps is disclosed having two semicylindrical parts which can be assembled together reliably in high speed manufacture to provide an assembled lamp less prone to failure during use. The first part includes double latch means together with locking pins and mates with a second part having means to receive these latching and locking elements when the parts are joined together. Other elements are also located on both parts to limit rotation of the assembled base about the annular lamp. Tapered conductive contact ends can also be used to facilitate high speed manufacture when inserted into tapered openings in the lamp base.
