Flickering Lights? You Might Have Chosen the Wrong Dimming Power Supply!

Beware! These Phenomena Are Stealthily Harming Your Visual Health

Unexplained headaches among students

These could all be caused by light flickering!

From desk lamps and classroom ceiling lights to mall spotlights and electronic screens, the modern world is filled with lighting fixtures that may harbor hidden flickering risks.

What Causes Light Flickering?

Light flickering refers to unstable fluctuations in light intensity over time. This phenomenon can stem from multiple factors:

Power Supply Fluctuations: Periodic changes in alternating current (50/60Hz) can cause brightness fluctuations. However, modern electronic ballasts and driver technologies (e.g., high-frequency drivers, DC conversion) have significantly reduced perceptible flicker.

Fixture Design: Certain lighting types, such as fluorescent lamps and older LED lights, are more prone to flickering due to their working principles. This often results from unstable energy conversion processes in electronic components.

Driver Circuit Issues: Poor-quality driver circuits may cause current fluctuations, leading to low- or high-frequency flickering.

The Hidden Dangers of Flickering

Though often imperceptible, flickering poses serious risks:

Eye Strain: Prolonged exposure to flickering lights can cause dry eyes, irritation, blurred vision, and fatigue.

Sleep Disruption: Severe flickering in nighttime lighting can interfere with circadian rhythms, suppressing melatonin production and impairing sleep quality.

Headaches & Migraines: Flickering may trigger or worsen neurological symptoms like headaches.

Psychological Impact: Physical discomfort from flickering (e.g., eye strain) may lead to irritability or reduced focus.
