SOCKET SUITED FOR REVOLVING THE LAMP ATTACHED THERETO
First Claim
1. A rotatable socket for a fluorescent lamp having a pair of base pins at the end thereof, comprising an insulating body having first and second recessed spaces;
- a rotator mounted rotatably by a fixed supporting axis within said first space of the insulating body and receiving the end of said fluorescent lamp, said rotator comprising an insulating main portion, a pair of conductive rings insulated from each other and disposed around the periphery of said insulating main portion, a pair of pliable metallic contact pieces for receiving said base pins of said fluorescent lamp, each of said contact pieces connected electrically with each of said conductive rings and set within apertures formed in said insulating main portion; and
a conductive stator fixed within the second recessed space and having a pair of resilient stiff conductor with terminals for a power supply and a pair of spring means with an uneven surface, each of said spring means being differently located at corresponding positions to each of said rings of said rotator, the uneven surfaces of said spring means being electrical connection with said conductive rings.

Abstract
A socket suitable for revolving a fluorescent lamp attached thereto comprises an insulating body having a first recessed portion therein for receiving a rotator in which a pair of base pins of the lamp can be inserted and having a pair of second recessed portions therein for receiving a stator to which lead-in wires for a power supply are connected, means for pivotally supporting the rotator within the first recessed portion, and a pair of conductive rings, insulated from each other, set around an insulating disc of the rotator and elastically engaged with conductive spring means of the stator so as to make electrical connection between the stator and the rotator.
