Abstract
Solid state lighting apparatuses and related methods are described. In certain embodiments, a solid state lighting apparatus adapted to operate with alternating current (AC) received from an AC power source is provided. The lighting apparatus can include a substrate and an array of solid state light emitters arranged on or supported by the substrate. Multiple solid state light emitter sets of the array can be arranged to be activated and/or deactivated at different times relative to one another during a portion of an AC cycle. The lighting apparatus can also include at least one reflective structure arranged between one or more solid state light emitters and at least one driver circuit component, to reduce or eliminate absorption by the driver circuit component(s) of light generated by the solid state light emitter(s).
