What is stroboscopic
Stroboscopic refers to the fluctuation of the luminous flux of an electric light source at a certain frequency. Pointing a mobile phone at a light source can often reveal a stripe distribution, which is caused by stroboscopic flashes. Some levels of stroboscopic activity are not noticeable and do not cause physical discomfort; But some stroboscopic things are a real problem.
As early as the 1990s, a large number of studies have found that light source stroboscopic lighting is closely related to neurological diseases such as migraine, headache, autism, visual fatigue and discomfort, and serious illusions can be caused by the human eye, leading to accidents. Do not underestimate the stroboscopic, different frequency and wave depth of the impact on people is not the same!
1. Stroboscopic stroboscopic effect, stroboscopic meaning,stroboscopic light,
stroboscopic effect psychology, a high speed stroboscopic,advantage of stroboscopic effect,stroboscopic definition
Human eye is a very complex system, individual differences are very large, for the vast majority of people, can detect the light flicker below 80Hz, when the human eye can perceive the change of light and dark, flicker frequency below 80Hz is also known as visible flicker (visible flicker). Visible stroboscopic is unacceptable for normal lighting or display.
2. Stroboscopic effect
For strobe above 80Hz, the human eye is not easy to detect, but it has a greater impact on the spatial perception of the human eye. For example, viewing moving objects as a series of still images is known as the Stroboscopic effect. Because of the stroboscopic effect, people can create the illusion that some fast-moving devices are running slowly or even stationary.
3. Phantom phenomena
Similarly, when the flashing frequency of the light source is 80Hz-2kHz, and the object in the environment remains static, the human eye is moving in the position or direction, the static light source will appear the extended light spot of the system, known as the phantom phenomenon, such as car taillights, or scanning the outdoor LED display.
4. The harm of stroboscopic
Stroboscopic light source has a close relationship with migraine, headache, autism, eye fatigue, blurred vision and other neurological diseases.
