Abstract
An LED lamp for replacement of directional incandescent lamps. The lamp comprises a screw base, a plurality of LEDs located in a first position, and a driver for the LEDs located in a second position separate from the first position. A lamp housing is secured to the screw base, with the LEDs and the driver being located in the lamp housing. A heat spreader is mounted in the lamp housing in proximity to the LEDs to remove heat therefrom. The heat spreader can also remove heat from the driver, or the driver can be located in proximity to the screw base and in thermal connection therewith so that heat is transmitted through the screw base.
