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.

Spline optic and lighting device

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.

Spline lamp with opposing light source orientation

Light bulb

In one aspect, the present invention provides light emitting devices, including light fixtures and luminaires. In some embodiments, a light emitting device comprises at least one light source, a lightguide operable to receive light from the at least one light source at a first location on the lightguide, at least one light extraction region optically coupled to the lightguide and a substantially non-scattering region along a portion of the lightguide.

Light emitting devices and applications thereof

An outcoupling optic and omnidirectional lamp are provided which enable an omnidirectional light distribution from a lamp with directional light sources such as light emitting diodes. Specific embodiments include the A-type lamp, A19.
