Abstract

A compact fluorescent lamp of high brightness is provided by a partition structure within the lamp that divides the tubular envelope into a plurality of interconnected sectors and also defines a core chamber that is not traversed by the discharge and is of predetermined size relative to the envelope. The core chamber serves both as a conduit or passageway for the lead-in conductors of one of the electrodes and as a means for enhancing the efficacy of the lamp by displacing the discharge outwardly toward the envelope walls and thus minimizing the 'light entrapment' effect deep within the envelope and the corner portions of the partition structure. The use of the core chamber as a lead wire conduit permits the electrodes to be located at the same end or opposite ends of the envelope--thereby providing 'odd-pass' discharge lamps of single-ended construction or 'even-pass' discharge lamps of double-ended construction that can be readily fabricated.
