Today, let's demystify what a light flicker is!

General-purpose fluorescent lamps are widely used with operating frequencies typically ranging from 20kHz to 60kHz. Although this frequency is generally comfortable to the human eye, under high-speed cameras or cameras, it can be observed that there is a very noticeable flicker. The flickering of the lights causes the ciliary muscle to continuously contract and relax to adapt to the environment. This prolonged and continuous tension can lead to fatigue in the ciliary muscle, which can have a severe impact on human eyes, particularly causing dryness, tearing, fatigue, and, in severe cases, a decline in vision.

Our Shenyang Runyangyipin Lighting Electrical Co., Ltd. now produces classroom eye-care lamps with no flicker, utilizing a high-frequency flicker-free power supply. Guangpu Rui eye-care lamps protect every student's eyes.
