dimmer

In order to be able to dim a lamp, you usually need a so -called dimmer. A dimmer is a control unit that regulates the brightness of the luminaire or lamp. At Table- and Stand -up a dimmer is often already installed in dimmable Pendulum- or Ceiling lights On the other hand, an external (LED) dimmer is usually required. There are different ways to dim a lamp, accordingly there are also different types of Dimmer.

On the one hand, there are phase intake dimmers that are suitable for light bulbs and halogen lamps with 230 volts (HV-Halogen lamps) and for Niedervolt-Halogenlampen (NV-Halogen), which are operated with conventional magnetic transformers. The principle behind this dimmer is that the current is switched on after the so -called zero passage of the sinus curve until it flows to the next zero.

On the other hand, phase section dimmers are also used, which are mainly used for dimming Niedervolt halogen lamps on electronic transformers, but are also suitable for incandescent lamps and HV halogen lights. This dimmer has a somewhat more complex functionality, which is exactly the opposite as with the phase intake dimmer. The current starts to flow immediately after the zero and ends shortly before it reaches the next zero.

There are also universal rooms who independently recognize the right method for dimming. However, fluorescent tubes cannot be dimmed to any of these wise men, which is why they need an electronic ballast (EVG dimmer). A dimmer can then be controlled by a rotary control or with a touch or touch dimmer.
