Abstract

See full text

A ring generating LED lamp includes a lens section which employs internal reflection to direct the light energy from a hemispherical emitter into a ring shaped output distribution. The ring shaped distribution projects above and below the plane of the LED source. The lens has multiple internal surfaces that direct light from the LED source to provide a ring shaped output distribution.
