Spline optic and lighting device

摘要

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.

1. A light emitting device comprising;
a. A light source and; b. An exterior envelope comprising optical splines and thermal splines wherein the external envelope forms a cavity within which less than 10% of light emitted from the light source enters and; c. a thermally conductive connection between light source and thermal spline; and d. an optical connection between light source and optical spline which inputs light within the exterior envelope in an orientation substantially perpendicular to the output surface of the exterior envelope.
