The strobe of the light source fluctuates due to the intensity of the light radiation of the light source, causing frequent and harmful flicker interference to the human eye, and infringes and interferes with the activity of the human brain.
Although the human eye has a phenomenon of persistence of vision, when the object moves quickly, when the image seen by the human eye disappears, the human eye can still retain images of the visual image for about 0.1-0.4 seconds. However, the human brain responds faster, so the light flicker still interferes with the human brain. The "strobbling damage" of lighting sources is extremely dangerous. E.g:
1) Migraine: Flashes of lighting can easily cause migraines. The 100 Hz flicker frequency is considered to cause migraine. In general, slow flashing is more harmful than fast flashing. And many migraine sufferers are just as sensitive to the strobe light.
2) Tired of anxiety: For the 120Hz frequency of the flashing light source may affect people's emotions, appear bored, anxiety and so on.
3) Photosensitive epileptic diseases: In light-sensitive people, epilepsy can occur even with short-time exposure to visible light in the range of 3-70 Hz. About one in 4,000 people are between the ages of 5 and 24, usually starting around puberty, and 75% of people are sensitive to light throughout their lives.
4) Eye fatigue decreased visual acuity: Illumination light scintillation tends to cause eye fatigue in some people. Students are prone to falling asleep under strobe light sources.
5) Attention Dispersion: It is easier for people to be more sensitive to stroboflash around the field of vision of the human eye. For example, on the way of the driver, the flashing of the signal light or the rapid flashing of the tail of the vehicle will always be attracted and affect traffic safety. A strobe light source illuminated by a running machine will produce erroneous judgments and cause an accident. Students are not able to concentrate in the class under the strobe light source.
6) Autism: Children with autism are particularly sensitive to changes in the environment, and the strobe in lighting increases the recurrence of this behavior.
Therefore, how to avoid strobe light is very important. Of course, it is best to avoid the strobe at the same time it is best to eliminate blue light hazards. At present, there are many types of LED lighting on the market. Although there are many kinds of LED lighting, there are many related exposures, such as the blue light exceeds the standard. Now that we have a new generation of OLED lighting, we can get more healthy and safe lighting, which is one of the hot technologies in the lighting industry. Compared with LED lighting, the spectrum of OLED lamps is close to natural light, which solves the problem of blue-violet ultraviolet damage. Moreover, OLED is a surface light source with a more uniform light distribution and no ghosting problem of point light sources. OLED lighting provides a better visual experience. It is due to the fact that OLED luminescent materials have a wide half-wave width and do not have much gaps, resulting in excellent color rendering index of OLED lamps and higher natural color reproduction. It can be said that OLED light sources have No glare, no glare, direct vision, even and soft light, is an artifact that protects the health of eyesight.
OLED lighting can be described as a promising industry. In 2015, OLED lighting global sales will reach 150 million US dollars, and it is expected to grow at an average annual growth rate of 75%, and it will reach 2.4 billion US dollars by 2020. By 2023, the total output value of OLED lighting is expected to soar to a maximum of US$6.7 billion.
