1. A solid state lamp comprising:

  • a plurality of flexible strips encapsulating bare, unpackaged light emitting diode (LED) dies, the bare, unpackaged LED dies being connected in series in the flexible strips, wherein the flexible strips are connected at one or more first terminals to a first voltage and connected at one or more second terminals to a second voltage;

    a support structure for supporting the flexible strips;

    an electrical connector affixed to the support structure for connection to an external power source for providing drive current to the strips; and

    wherein the flexible strips or the support structure comprise one or more folds configured to allow the flexible strips or the support structure to extend or contract along a longitudinal direction and correspondingly decrease or increase a dimension of the solid state lamp in a transverse direction orthogonal to the longitudinal direction, where an illumination profile produced by the solid state lamp varies depending on the dimension of the solid state lamp.
