Abstract
A solid state (light emitting diode) lamp in numerous configurations have improved thermal management by providing a direct thermal pathway from the plurality of LED chips to the threaded screw base (standard 100.about.240 VAC lamp socket), or power coupling. The control circuitry is disposed opposite the printed circuit board and LED chips with respect to the heat sink so that the heat sink is interposed between the printed circuit board and the control circuitry. The LED chips are powered using a high voltage/high current configuration. The light radiation pattern is infinitely adjustable (very wide through very narrow) via a system of easily interchangeable lenses. The solid state lamps can be mass produced rapidly at significantly lower cost with very high luminous intensity. ESD protection may be included to protect the LED chips from electrostatic discharge damage.
