Abstract
A lamp comprises an optically transmissive enclosure. A plurality of LEDs for emitting light are located to emit light toward the enclosure. The enclosure has at least one reflective area disposed on the enclosure to reflect a portion of the light into the enclosure to create a desired luminous intensity distribution.
Claims19
A lamp comprising:
- an optically transmissive enclosure;
- a base connected to the optically transmissive enclosure;
- a plurality of LEDs for emitting light disposed on at least one mount and facing the interior of the enclosure, the plurality of LEDs emitting light when energized through an electrical path from the base;
- at least one reflective area spaced from the base and provided on the optically transmissive enclosure wherein the at least one reflective area comprises a reflective tape that is at least approximately 90% light reflective.

A lamp comprising:
- an optically transmissive enclosure;
- a plurality of LEDs for emitting light toward the enclosure;
- the enclosure having at least one reflective area disposed on or within the enclosure to reflect a portion of the light into the enclosure to create a desired luminous intensity distribution wherein a first one of the at least one reflective area is surrounded by the optically transmissive enclosure, the first one of the reflective area being at least approximately 90% light reflective over the entire reflective area.
