Abstract

A lighting assembly has an elongated housing which contains a plurality of light emitting diodes that send light from one side of the housing. Connectors at the ends of the housing are provided to connect the lighting assembly into standard sockets of a fluorescent light fixture that has been modified to power the light emitting diodes. At least one of the connectors has a releasable holding mechanism that allows the housing to be rotated with respect to the sockets to aim the light is a desired direction and then hold the housing in that orientation.

15. The lighting assembly as recited in claim 1 wherein the locking member comprises a first torsion spring wound around and releasably engaging the rotary fitting, and having a first portion that engages the contact cap and has a second portion that engages the release sleeve, wherein engagement of the first torsion spring with the rotary fitting resists rotation of the housing with respect to the contact cap and wherein motion of the release sleeve relative to the contact cap loosens engagement of the torsion spring with the rotary fitting thereby enabling the housing to rotate with respect to the contact cap.

16. The lighting assembly as recited in claim 15 wherein the swivel connector further comprises a bias member biasing the contact cap with respect to the rotary fitting.

17. The lighting assembly as recited in claim 15 wherein the swivel connector further comprises a bias member biasing the release sleeve with respect to the rotary fitting.

18. The lighting assembly as recited in claim 15 wherein the locking member further comprises a second torsion spring wound around the rotary fitting, the second torsion spring having a third portion that engages the contact cap and a fourth portion that engages the release sleeve, wherein the second torsion spring releasably engages the rotary fitting to resist rotation of the housing with respect to the contact cap and wherein motion of the release sleeve relative to the contact cap loosens engagement of the second torsion spring with the rotary fitting thereby enabling the housing to rotate with respect to the contact cap.

19. A lighting assembly comprising:

a housing;
