1. A LED lamp comprising:
- an enclosure having an exterior surface that is exposed to the ambient environment, the enclosure being at least partially optically transmissive;
a base connected to the enclosure;
an LED assembly comprising a plurality of LEDs for emitting light when energized though an electrical path from the base and an LED board where the plurality of LEDs are mounted on a mounting surface of the LED board, the LED assembly and the plurality of LEDs being mounted outside of the enclosure for transmitting light through the enclosure into the interior of the enclosure, the LED board having a second surface that is exposed to the ambient environment for transmitting heat from the plurality of LEDs and dissipating heat to the ambient environment where the mounting surface and the second surface are surfaces of the same physical component, wherein the plurality of LEDs are disposed in an optically transmissive channel formed in the enclosure, the channel defining a recess that substantially surrounds the light emitting portion of the plurality of LEDs such that the second surface is formed to conform to the curvature of and be coextensive with the exterior surface of the enclosure.

Abstract
A LED lamp includes an optically transmissive enclosure and a base connected to the enclosure. LEDs are mounted on a substrate for emitting light when energized though an electrical path from the base. The substrate and the LEDs are mounted outside of the enclosure for transmitting light from the plurality of LEDs into the enclosure.
