Flicker in LEDs

Written on

Many home owners have concerns about using automated dimmers and LED lighting loads because of flickering issues. Needless to say, flicker in LED lighting is a main issue which several home owners face. However, new-age LEDs have changed it all for good, as they are hardly subject to flicker. Many companies provide power-efficient LED lighting solutions that enlighten your premises like never before.

Flicker is basically a constant fluctuation of the light output between its transitions from on to off. In other words, it is a quick and repeated change in light intensity and it appears as a light that flutters and appear unsteady. Flicker is caused when voltage supplied to the source of light changes or the power line itself fluctuates.
Flicker in LEDs can make people uncomfortable, and might cause headaches and harm to the human eye. Flicker can also lead to malaise and visual impairment. The retina can sense flicker up to 200 Hz, but numerous tests have shown that flicker above 160 Hz can be harmful to our health.

LED requires little power as compared to traditional lighting. Keeping up with the trend of replacing incandescent and fluorescent lights with improved solutions, LEDs strive to provide more efficient and longer-lasting solid-state lighting (SSL). LEDs are more resistant to flicker ensuring your health and the safety of your home.
LEDs use solid-state lighting (SSL) which is a direct-current output module. This means that as long as consistent current is supplied, the LED will stay illuminated without any chances of flicker. However, in rare cases, LEDs may also oscillate in light output causing it to flicker.

A lot of home owners ask themselves how they can avoid flicker in LED lights. A well designed driver can reduce the flicker coming from an SSL LED luminaire. Drivers are equipped with capacitance that filters out the AC ripple component. The current is then filtered providing anti-flicker light output.
Choosing an LED without flicker comes with trade-off of reliability in many cases. This is because certain companies use low-quality capacitors in LEDs. However, there are still companies that stick to quality perfection and offer impeccable LED lighting solutions.
