    Abstract: A LED lamp includes an at least partially optically transmissive enclosure and a base connected to the enclosure. A plurality of LEDs are located in the enclosure and are operable to emit light when energized through an electrical path from the base. An optical interface is positioned in the enclosure for electrically isolating a live electrical component and for receiving at least a portion of the light. The optical interface includes a light modifying property for modifying a characteristic of the portion of the light.
