Flickerhäiriö

Flickerhäiriö, also known as flicker disturbance or stroboscopic effect, is a visual phenomenon that occurs when a light source is rapidly turned on and off. This can create the illusion of movement or a pulsating appearance in objects illuminated by the flickering light. The effect is more pronounced with certain types of lighting, such as fluorescent lamps or some LED lights, and depends on the frequency of the flicker.

The perception of flicker häiriö is influenced by several factors, including the frequency and intensity of the light source, the observer's visual system, and the nature of the object being viewed. High-frequency flicker may not be noticeable to the human eye but can still cause visual discomfort or fatigue in some individuals. Lower frequencies, however, can be perceived as distinct flashes.

Flicker häiriö can have various implications. In industrial settings, it can pose safety risks, particularly in environments with fast-moving machinery, as it can distort the perception of speed and motion. This can lead to accidents if workers misjudge the movement of equipment. In other contexts, it can be a source of annoyance or discomfort, affecting concentration and potentially contributing to headaches or eyestrain.

Efforts to mitigate flicker häiriö include using lighting technologies with higher flicker-free performance, adjusting lighting frequencies, and implementing visual shielding where necessary. Regulations and standards in some regions address flicker levels in lighting installations to ensure workplace safety and public well-being.
