Stroboscope is the constant fluctuation of light during the switching cycle. It's a flicker that occurs because of the frequency. A stroboscope is a light source that blinks quickly and repeatedly over time. Popular speaking, is the feeling of light beating, unstable, this phenomenon is the so-called stroboscopic.

Almost all types of lights are prone to flicker, including incandescent bulbs, halogens, and even LED bulbs. But each light has a different effect. In incandescent and halogen lamps, for example, the filament temperature responds slowly to changes in current, so you won't notice the flicker. The LEDs respond almost immediately to the current change, so the blinking will be even more noticeable.

Relative to LED lighting products, dimming is an essential function, and dimming is exactly one of the causes of stroboscopic flashing. When the dimming function is added to the dimmable led power supply, the strobe is often further aggravated. Especially when the dimming is dark, the depth of fluctuation is relatively large.
