1. A solid state lighting apparatus comprising;

  • a solid state lighting array comprising a plurality of LEDs and a plurality of pcb substrates;

    a first heat sink comprising a flexible portion and a plurality of LED mounting frames operable to support the plurality of pcb substrates at predetermined angles between about ±

    45°

    on which the solid state lighting array is mounted;

    an expander portion comprising electrical components and at least one tension screw;

    a lens assembly placed over the LEDs on the first heat sink such that each LED is focused in a predetermined pattern such that the light flux has a normal type distribution about the central axis projecting orthogonally from the center point of the solid state lighting apparatus; and

    an outer cover operable to function as a second heat sink;

    wherein the expander portion is operable to radially expand against the flexible portion when at least one tension screw is tightened into the expander portion such that the flexible portion is placed in thermal communication with the outer cover.
