Özet:

A phenomenon of luminous flux flicker of artificial light lamps of general and industrial use is analyzed in the article. The analysis shows that luminous flux flicker adversely affects the human condition. However, most manufacturers of lamps not knowingly induce flicker performance for their products. Difficult professional devices are used to check the availability of flicker and measure its depth in the market of electronic devices. They are virtually inaccessible to the public taking into account the producing countries and pricing. On this basis, relatively simple device for analyzing the luminous flux flicker is proposed. It is based on a converter of optical radiation – photodiode and detector-oscilloscope. With the developed device, studies of the most common artificial light lamps that are present in the domestic market were conducted. The resulting waveforms of changes for luminous flux in time were obtained and flicker coefficients were calculated. Studies were found that certain examples of widely used lamps have unacceptable level of luminous flux flicker. Thus it is shown that it can’t trust the manufacturer advertising when designing of high-quality lighting systems, and should, if possible, check for flicker.
