What is a Dimmer?

Dimmer


Below are various definitions for a dimmer.
  • A remote device which reduces the light output of a stage lighting fixture by reducing the total wattage it receives, commonly grouped in banks, panels or packs. Present technology usually has a dimmer per circuit, as opposed to systems where a limited number of high-wattage dimmers are patched to a larger quantity of circuits.

  • In lighting, the electrical device (technically known as a potentiometer) that regulates the current passing through the bulb filaments and, thereby, the amount of light emitted from the lighting instruments.

  • Electronic controls that allow stage lighting to fade up or down slowly, as opposed to being on or off only.

  • A control that regulates light levels.

  • Device which provides adjustable voltage to a lighting fixture to control light output. Can also be a term to refer to a mechanical device, such as a shutter, that controls output.

  • An instrument used to change the voltage of lights on the set, regulating in this way thier intensity. NOTE: Not recommended for color cinematography, as the color temperature of the lights will also change.

  • Controls the brightness of a particular fixture. A dimmer pack is a device used to control a fixture from a remote control panel. Dimming may also be a feature within an intelligent light or a specific control device.

  • A device that controls levels of light by varying the electric current.

  • a device in the electrical circuit used for varying the brightness of lamps in a lighting installation. Dimming controls are ideal for any number of rooms because they allow you to change design the lighting to suit each mood and activity.

  • an electronic device designed to regulate light output of incandescent and halogen lamps; and fluorescent lamps in fixtures equipped with special dimming ballasts.

  • To change the brightness of the display e.g. during night driving.

  • a rheostat that varies the current through an electric light in order to control the level of illumination
