The present lighting element uses, as a source of light generation, electronically activated light emitting elements, such as light emitting diodes, organic crystals and the like to provide one or more functions and are surface mounted on a flexible substrate, such that the substrate can bend and conform to a pre-established structure. In addition, standoffs of varying lengths are used to provide adjustable distances between the flexible substrate and the housing of the LED light bulb to provide adjustable light dispersion patterns. In this case, the circuit board is adapted to extend about and fit within the interior surface of a light bulb with the light emitting elements carried on the circuit board. A center post can be used to extend electrical conductors to the circuit board from the base and, if required, a power supply can also be carried in the post. A portion of the circuit board itself could also effectively operate as the post. Methods for making same are also provided.
