Anti-collision lights, also called beacon lights or strobe lights, are a set of lights required on every aircraft to improve visibility to others, as well as collision avoidance measures by warning other pilots. [1] Historically they have used incandescent light bulbs, but recently LED lamps have been used.
Flicker vertigo, sometimes called the Bucha effect, is "an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light." [ 1 ] It is a disorientation -, vertigo -, and nausea -inducing effect of a strobe light flashing at 1 Hz to 20 Hz, approximately the frequency of human brainwaves .
A strobe light flashing at the proper period can appear to freeze or reverse cyclical motion. Special calibrated strobe lights, capable of flashing up to hundreds of times per second, are used in industry to stop the appearance of motion of rotating and other repetitively operating machinery and to measure, or adjust, the rotation speeds or ...
An embedded flashing-light system, or an in-pavement flashing-light system, is a traffic safety device installed at pedestrian crossings or intersections to enhance driver awareness of pedestrians or traffic signals. These systems typically consist of LED lights embedded within the road surface, positioned to face oncoming traffic or pedestrians.
Solutions include deploying the lighting over a full 3-phase supply, or by using high-frequency controllers that drive the lights at safer frequencies [15] or direct current lighting. [citation needed] The 100/120 Hertz stroboscopic effect in commercial lighting may lead to disruptive issues and non-productive results in workspaces such as ...
