An illumination apparatus comprises a lighting segment that includes a plurality of lighting sections. Each of the sections comprises a printed circuit board having a solid state optical emitter mounted thereon. The sections are interconnected by printed circuit board connectors, which serially position the printed circuit boards with edges of adjacent printed circuit boards proximate to each other. The connectors are deformable to alter the orientation in response to an applied force. The sections are electrically connected to each other such that the solid state optical emitters are electrically connected in series. The segment has a current regulator that controls current through the solid state optical emitter.
