  2. Dimmer - Wikipedia

    en.wikipedia.org/wiki/Dimmer

    A thyristor dimmer rack An electrical schematic for a typical SCR-based light dimmer Solid-state , or semiconductor , dimmers were introduced to solve some of these problems. Semiconductor dimmers switch on at an adjustable time (phase angle) after the start of each alternating-current half-cycle, thereby altering the voltage waveform applied ...

  3. Compact fluorescent lamp - Wikipedia

    en.wikipedia.org/wiki/Compact_fluorescent_lamp

    The dimmer switch used in conjunction with a dimmable CFL must be matched to its power consumption range; [58] many dimmers installed for use with incandescent bulbs do not function acceptably below 40 W, whereas CFL applications commonly draw power in the range 7–20 W. Dimmable CFLs have been marketed before suitable dimmers are available ...

  4. Electrical ballast - Wikipedia

    en.wikipedia.org/wiki/Electrical_ballast

    A dimmable ballast is very similar to a rapid start ballast, except that the autotransformer is connected to a dimmer. A quadrac type light dimmer can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled. A resistor of about 10 kΩ is required to be connected in parallel with the ...

  5. 0-10 V lighting control - Wikipedia

    en.wikipedia.org/wiki/0-10_V_lighting_control

    Dimming devices may be designed to respond in various patterns to the intermediate voltages, giving output curves that are linear for: voltage output, actual light output, power output, or perceived light output. Receivers have a nominal input impedance of 100±20 kΩ (i.e., maximum 1.0±0.2 mW at 10 V) 0-10V dimmer

  6. Stage lighting - Wikipedia

    en.wikipedia.org/wiki/Stage_lighting

    A dimmer is a device used to vary the average voltage applied to an instrument's lamp. The brightness of a lamp depends on its electric current, which in turn depends on the applied lamp voltage. When the applied voltage is decreased, a lamp's electric current will also decrease, thus reducing the light output from the lamp (dimming it).

  7. Touch-sensitive lamp - Wikipedia

    en.wikipedia.org/wiki/Touch-sensitive_lamp

    Video demonstrating the operation of a touch-sensitive lamp. A touch-sensitive lamp is a combination of a lamp and a touch switch. They act on the principle of body capacitance, activated by human touch rather than a flip, push-button, or other mechanical switch. They are popular as desk and nightstand lamps. Touch-sensitive lamp switches may ...

    en.wikipedia.org/wiki/Philips_Hue

    Philips Hue is a line of color-changing LED lamps and white bulbs which can be controlled wirelessly. The Philips Hue line of bulbs was the first smart bulb of its kind on the market. [3] The lamps are currently created and manufactured by Signify N.V., formerly the Philips Lighting division of Royal Philips N.V. [1] [4]
