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. Opposing orientation of light sources is utilized to create integrated optical and thermal splines for improved thermal and optical performance.
