Patent ID: 8093823

Claim:
A replacement light for use in a fixture having a double ended bi-pin socket set designed for fluorescent tubes wherein the light comprises: an elongate support defining a substantially planar mounting surface; a plurality of light emitting diodes mounted along the mounting surface of the elongate support so that light emitted from the plurality of light emitting diodes is substantially directed away from the mounting surface; a pair of bi-pin connectors compatible with said bi-pin socket set disposed at opposed ends of the support; a cover for the elongate support arranged such that light from the light emitting diodes passes through the cover; and a power supply circuit supplying power to the plurality of light emitting diodes and mounted within a space proximate the elongate support and the cover, the power supply circuit including an AC-to-DC converter coupled to at least one of the pair of bi-pin electrodes to receive AC current and a PWM regulator configured to receive rectified DC current from the AC-to-DC converter and to provide regulated DC current to the plurality of light emitting diodes; and wherein at least some of the plurality of light emitting diodes are connected in series.
