  5. Power-line flicker - Wikipedia

    en.wikipedia.org/wiki/Power-line_flicker

    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.

  6. Light characteristic - Wikipedia

    en.wikipedia.org/wiki/Light_characteristic

    A Morse code light is light in which appearances of light of two clearly different durations (dots and dashes) are grouped to represent a character or characters in the Morse Code. For example, "Mo(A)" is a light in which in each period light is shown for a short period (dot) followed by a long period (dash), the Morse Code for "A".

  7. Temporal light artefacts - Wikipedia

    en.wikipedia.org/wiki/Temporal_light_artefacts

    Temporal light artefacts (TLAs) are undesired effects in the visual perception of a human observer induced by temporal light modulations. Two well-known examples of such unwanted effects are flicker and stroboscopic effect. Flicker is a directly visible light modulation at relatively low frequencies (< 80 Hz) and small intensity modulation levels.

  8. LED tube - Wikipedia

    en.wikipedia.org/wiki/LED_tube

    The 4th generation of LED tubes offers a solution to the flickering problem. The flickering is measured using so-called flicker index or flicker percentage value. Elimination of flickering allows high-quality video recording and slow motion capture, as well as certain machine vision applications in premises equipped with flicker-free lights. [3 ...
