LIGHT DIFFUSING OPTICAL FIBERS AND LIGHT EMITTING APPARATUSES INCLUDING LIGHT DIFFUSING OPTICAL FIBERS

摘要

Light diffusing optical fibers and light emitting apparatuses including light diffusing optical fibers are disclosed. In one embodiment, a light emitting apparatus includes a base, a transparent or translucent enclosure affixed to the base, a light diffusing optical fiber including a coiled filament enclosed within the enclosure, and a light source optically coupled to the light diffusing optical fiber. The coiled filament includes a glass core, an outer surface, and a plurality of light scattering structures situated within the coiled filament for scattering light through the outer surface of the coiled filament. The coiled filament has a loss in a range of 0.5 dB/turn to 10.0 dB/turn at a turn radius of less than 50 mm.

1. A light emitting apparatus comprising:
a base; a transparent or translucent enclosure affixed to the base; a light diffusing optical fiber comprising a coiled filament enclosed within the enclosure, wherein:
the coiled filament comprises a glass core, an outer surface, and a plurality of light scattering structures situated within the coiled filament for scattering light through the outer surface of the coiled filament;the coiled filament has a loss in a range of 0.5 dB/turn to 10.0 dB/turn at a turn radius of less than 50 mm.; and a light source, wherein the light source is optically coupled to the light diffusing optical fiber, such that at least a portion of light emitted by the light source enters the light diffusing optical fiber and is scattered away from the glass core and through the outer surface of the coiled filament by the plurality of light scattering structures.
