Abstract

A light engine that includes electrical leads extending into a supporting stem and a filament assembly having a V-shaped geometry in electrical connection with the electrical leads. The filament assembly includes at least two light emitting diode (LED) filaments wherein a first end of the filament assembly is in electrical contact with the electrical leads and provides an apex portion of the V-shaped geometry, and a second end of the filament assembly opposite the first end has a second width greater than the first width of the apex portion. An electrically conductive pathway connects the at least two light emitting diode (LED) filaments at the second end of the filament assembly.
