Abstract

An LED light tube assembly includes a tube assembly (1) having therein first contacts (311) and second contacts (321); and a head assembly (2) mounted to one end of the tube assembly (1) and having at least two snaps (22) each with a first leg (221) and second leg (222) extending toward each other to detachably and electrically connect to the first contacts (311) and the second contacts (321) so that detachment of the at least two snaps (22) facilitates separation of the head assembly (2) from the tube assembly (1).
