Problems solved by technology

However, because LEDs require some minimum forward voltage to turn on, the LEDs may only turn on for a portion of the rectified AC waveform, which may cause visible flicker, may undesirably reduce the power factor of the system, and / or may increase the power factor of the system. Resistive losses in

Abstract

A solid state lighting apparatus can include a substrate having first and second opposing surfaces, wherein at least one of the opposing surfaces is configured to mount devices thereon. A string of chip-on-board light emitting diode (LED) sets, can be on the first surface of the substrate and coupled in series with one another. An AC voltage source input, from outside the solid state lighting apparatus, can be coupled to the first or second surface of the substrate.
