Flikkeringen

Flikkeringen is a Swedish term that translates to "flickering" or "flashing" in English. It is most commonly used to describe a visual phenomenon where light sources appear to repeatedly turn on and off or change in intensity rapidly. This can occur with natural light, such as the intermittent rays of the sun through clouds, or with artificial light, such as a faulty light bulb or a strobe light.

In a technical context, flikkeringen can refer to the temporal variation in luminous intensity of a light source. This variation can be caused by various factors, including fluctuations in power supply, the characteristics of the light-emitting device itself, or external environmental conditions. In some applications, such as visual displays, controlled flikkeringen is used for specific effects or to convey information. However, uncontrolled or excessive flikkeringen can be distracting, cause discomfort, or even trigger photosensitive epilepsy in susceptible individuals.

The perception of flikkeringen is influenced by the frequency and amplitude of the light variations, as well as the observer's visual system and the surrounding visual context. Standards and regulations exist in many countries to limit permissible levels of flikkeringen in lighting systems to ensure visual comfort and safety. The term is also sometimes used metaphorically to describe any fleeting or intermittent occurrence.
