Abstract
An omnidirectional LED filament holder and lighting device comprising the same comprises a filament tree supporting a plurality of linear LED filaments having a twisted orientation relative to a central support stalk of the filament tree. When arranged within a globe of a lighting device, the omnidirectional LED filament holder provides a lighting device providing omnidirectional light emission usable for general lighting applications while providing a desirable aesthetic for the lighting device.
