Multiple-tier omnidirectional solid-state emission source

摘要

Multiple-tier omnidirectional solid-state emission source capable of dispersing light in flexible distributions or custom-intensity distributions which throw more light forward, to the side alternatively, or in all directions. This optical light control requires multiple-surface manipulation of the directions of the light energy bundles emerging from solid-state light sources. Producing uniform light up to 325 degrees in the vertical direction through the combined implementation of multi-stage light guiding for remote source elongation and multiple-tiers of TIR, refraction, and scatter for remote source emission and control. Combining the efficient light production of an LED chip with that of a directly coupled optic results in high efficiency custom distribution to direct light where required. The optical light manipulator consists of a dielectric or reflector collector section, spline light-pipe section used to clear the cross-sectional area of a thermal dissipation device and a section which either externally, internally, or combinatorially feeds multiple-tier TIR/refractor elements.

主权项

1. A multiple-tier omnidirectional solid-state emission source comprising:
a dielectric TIR optical control surface which directs and concentrates light to a secondary TIR lightguide surface; a secondary concentration occurs near a first zone after which a portion of the light is allowed to exit; light emanating after control surface fills indirect intensity zones and additional light traverses through air before re-entering the optical device in a second zone; and the end result is an omnidirectional field of light as a result of catadioptric control of a plurality of surfaces.
