Flicker Free Led Driver

Light strobe, even when the radiation is still life, the naked eye can not detect the strobe, but also prone to visual fatigue, damage vision.

If it is to observe the moving objects (especially faster) and in the light under the fine work, not only depending on the material is unclear, the greater the damage to the eyes.

Questions about flicker-free light may arise at this point. To be fair, it should be pointed out that fluorescent tubes operated with conventional or low loss ballast also flicker at 100 Hz and the light output is reduced at lower ambient temperatures. Fluorescent lamps operated with an ECG, including energy saving lamps, work at 44 – 50 kHz so that the lamps normally do not flicker. In reality, however, things are a little different. While a higher switching frequency is used, the input capacitors are to small for cost reasons. This causes the high frequency circuit in the lamp to be supplied with a strongly pulsating voltage. This pulsation creates a brightness modulation in the emitted light which is why these lamps often have a rather high level of flicker at 100 Hz.
