Abstract
An LED plug-in lamp is disclosed that has a plug head which converts from a G24Q 4-pin plug head to a G24D type 2-pin plug head when a collar structure on the plug head is rotated relative to a fixed stage structure. The collar structure has two pin-stop features and two pin hole cover features. Rotating the collar structure relative to the fixed stage structure moves the two pin-stop features and allows the two reachable contact pins can be retracted through corresponding pin holes on the fixed stage structure and places ends of the pin hole cover structures over corresponding pin holes.
