US Patent 7234842 Replaceable LED socket torch and lighting head assembly

A replaceable lighting head assembly comprised of a high output LED (Light Emitting Diode) socket torch package, vertically aligned thermal heat sink, and electrical connector coupled with a secondary housing unit that conducts heat received from the heat sink to the external environment and acts as a conduit for the external electrical source. This second component also serves as a building block for further fixture design. In this manner, state-of-the-art LED's can be used to provide light within a small, durable package which in turn, provides lighting designers with the opportunity to explore new fixture designs and to improve the quality, energy-efficiency, safety and longevity of existing products.
