Claim:
1. A lighting device comprising: a base adapted to be coupled with a light fixture socket; an optic having a curved inner surface defining an optical chamber; a driver circuit positioned in electrical communication with the base; and a flexible circuit board positioned within the optical chamber along and generally circumscribing a longitudinal axis of the optical chamber and in electrical communication with the driver circuit, the flexible circuit board comprising a plurality of longitudinal sections, each longitudinal section comprising wherein the first inclined section is positioned in the direction of the base relative to the second inclined section, wherein each of the first and second inclined sections has an LED of the plurality of LEDs positioned thereon such that light emitted by the LED is incident upon the optic; wherein the flexible circuit board is positioned so as to define a bounded section of the optical chamber; and wherein the driver circuit is positioned at least partially within the bounded section of the optical chamber; a structural member; and a longitudinal translation device; wherein the flexible circuit board is fixedly attached at a first end to the structural member; wherein the longitudinal translation device is operable to translate longitudinally a second end of the flexible circuit board.
