In visual perception, flicker is a human-visible change in luminance of an illuminated surface or light source which can be due to fluctuations of the light source itself, or due to external causes such as due to rapid fluctuations in the voltage of the power supply (power-line flicker) or incompatibility with an external dimmer.
Power-line flicker is a visible change in brightness of a lamp due to rapid fluctuations in the voltage of the power supply. The voltage drop is generated over the source impedance of the grid by the changing load current of an equipment or facility. These fluctuations in time generate flicker.
A common dual dimmer module used in stage lighting A dimmer. A dimmer is a device connected to a light fixture and used to lower the brightness of the light.By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.
I am having an electrical problem with my 2008 Nissan Altima — all the lights on the dashboard flicker on and off at random times.
In a cathode-ray tube television, the reduced output voltage will make the screen image smaller, dimmer and fuzzier. A linear DC regulated supply will maintain the output voltage unless the brownout is severe and the input voltage drops below the drop out voltage for the regulator, at which point the output voltage will fall and high levels of ...
Joel Solon Spira (March 1, 1927 – April 8, 2015) was an American inventor, entrepreneur, and business magnate.. He invented a version of the light-dimmer switch for use in homes around the United States and led his Lutron Electronics Company into the production of lighting controllers.
