Abstract:
An LED based lamp has an optically transmissive enclosure connected to a base. The base may include a heat sink. A substrate is positioned in the enclosure and supports a plurality of LEDs where the periphery of the substrate has alternating recessed portions and protruding portions that define a plurality of laterally extending projections. One LED is located on each of the projections to increase the amount of down light generated by the lamp.
