Flicker experimental set up and visual perception of flicker

摘要

This paper talks about the measurements of luminous flux of different light sources and the production of an experimental set up for the purpose of observing light phenomena in LEDs. With the help of measurements, an insight on how luminous flux usually fluctuates in the various types of lamps was obtained. For easy observation and study of temporal light artefacts in LEDs, such as flicker and stroboscopic effect, an experimental set up with an option to adjust the supply voltage signal was constructed. At the end, we also show some of the results of the visual perception of flicker.
