Dimming lighting system

Dimmable lighting systems were developed originally to meet the need for lighting that was easier on the eye. To an increasing extent, these systems are now also being used for cost saving reasons. Users can control the lighting with remote controls and switches, or control circuits with daylight sensors can be used. Leading edge phase dimming is used for low voltage tungsten halogen lamps operated with magnetic transformers. Trailing edge phase dimming is generally used for those lamps operated with electronic transformers. Compact fluorescent lamps (dimming range 3% to 100%) and fluorescent tubes (dimming range 1% to 100%) with electronic control gear are dimmed via a 1-10 V interface. Cables can either be laid separately (recommended for cable lengths > 100 m) or together, provided the requirements of wiring regulations are met.
