According to Benbro Electronics , electronic designers must consider several factors to achieve power quality in lighting systems. Since the advent of new technologies, such as LEDS, Compact Fluorescent Lighting, High Intensity Discharge lighting this point is even more significant.
Power quality is the ability of an electrical system to deliver power in the safest, most efficient manner.
Many new lighting technologies, while very efficient, can adversely affect power systems through harmonics, which decrease power quality.
Poor power quality management inevitably leads to an increase in operational costs and places an unnecessary strain on already dwindling resources.
As such, lighting systems should be driven by efficient and sustainable power sources that will not unnecessarily burden the power grid but still provide the ideal electrical environment for advanced lighting systems.
There are several standards, which exist for lighting industry compliancy. The standard which most directly affects power quality is the standard for limitations on harmonic currents, or EN61000-3-2 Class C limits.
