<p>In re application of Robert R. Abernethy For "FLUORESCENT LAMP INSERT WITH CONDUCTIVE ROD SUPPORT" A non-light emitting insert for a fluorescent lighting fixture is used in place of a fluorescent lamp to complete a plural lamp ballast circuit so that the ballast is effective to illuminate properly any remaining fluorescent lamp coupled therein. The insert appears externally as a conventional fluorescent lamp including end electrical terminations that fit in the sockets of a fluorescent lighting fixture, and to an extent the insert duplicates the electrical effect of a lamp in a two lamp ballast circuit. Using the insert a reduction in the light output and a substantially corresponding reduction in consumed electrical power are achieved for a plural lamp fluorescent lighting fixture arrangement while at the same time the components of the ballast circuit are operated at reasonably normal electrical and temperature levels. Moreover, an electrically conductive rod extending between the ends of the tubular portion of the insert may be employed both to support the insert at least partially relieving the tubular portion of that function and to effect the substantial completion of the ballast circuit.</p> |
