More safety everywhere for everyone
Luminous flux oscillations (causing output voltage ripple) generated in certain environmental conditions, both under sudden light variations and constant light, even if not consciously perceived, create a disturbance and may cause hazards in the workplace.
Recent research has shown that a stable lighting increases the safety and productivity of workers. According to some studies, about one person out of 4000 is particularly sensitive to flashing lights at a frequency between 3 and 70 Hz. This flicker can induce serious disorders.
More stable images
Luminous flux oscillations have clear impacts on monitors where images may appear fuzzy or blurry. Therefore, light stability is a key requirement for obtaining high quality videos. Interference with TV/photo camera is usually within the 60 Hz to 1k Hz interval.
No more eye strain
A long-term exposure to flicker at high frequencies (between 70 and 160 Hz) may result in discomfort, headache and damages to the retina. A good high-frequency switching driver will minimize the alternate current component of the voltage ripple and of the output signal. With flicker-free lamps featuring minimal glare (UGR<19) and good colour rendering (CRI 90), you can create a healthier and more comfortable lighting environment.
Clarifications on Low Optical Flicker products
UL has been studying the issue and is getting prepared to issue a dedicated regulation. In the meantime, it is developing a standard that will classify luminaires based on their level of flicker.
The approval mark is identified with the “low-flicker risk” logo that calculates the maximum percent of flicker to 8% at 50Hz and to 10% at 60Hz.
Visible flicker
Flicker produced by Led fixtures at frequencies below 60hz and that depend on several factors including the ripple of the direct current output of a power supply.
