Stroboscopic Effect of LED Lights

The concept of healthy lighting is becoming more and more popular, and more and more people pay attention to the stroboscopic problem of LED lights. Today we will take a look at the in-depth analysis of the stroboscopic effect of LED lights.

In addition to being annoying, the flickering light can cause serious illnesses such as headaches, visual impairment. Even if the flicker is slight, for example at a high frequency of 100 to 150 Hz, it is invisible to our eyes, but the brain can still detect and react to it, with potentially negative consequences.

Almost all types of lights have stroboscopic, but each light has a different effect. For example, in incandescent and halogen lamps, the filament temperature reacts slowly to changes in current so you won't notice the effect of flickering. However, the LED strobe is caused by the driver. For current changes, the LED responds almost immediately, so the flicker is more noticeable.

And in daily life, you can see the strobe by using the mobile phone camera, but this is not a way to judge whether the product is qualified. The phone is not a strobe detection tool because the phone lens has a rolling shutter effect, but it can be a reference tool. If you use your phone camera under severely strobed lights, it's easy to find the light and dark ripples on your phone screen.

In recent years, the public's voices and requirements for health lighting are getting higher and higher. In order to effectively improve the quality of light, more and more consumers have already learned about the potential damage caused by stroboscopic. The stroboscopic problem must be faced with solve. Having a healthy light environment is a basic requirement, and choosing a good LED driver can minimize the negative effects of the strobe. Creating a healthy lighting environment requires the joint efforts of LED lights manufacturers and power supply manufacturers.
