Abstract

Optical and thermal splines are integrated in the external envelope of a non-planar lamp allowing the optical output of discrete light sources such as LEDs to be distributed for uniform output and the achievement of desired light distributions such as omnidirectional output. Integrated thermal splines and perimeter location of light sources allow for improved thermal management without significantly compromised optical performance.
