LED 입력전원에 따른 광플리커 분석

Today, LED lighting is very famous as lighting source. But the situation is going because many LED lights as a light flickering ill effects on the human body loses the confidence of the performance. The flickering light is determined by the current waveform injected into the LED. Temporal light intensity of the light flickering is changed due to the change with time of the current waveform. In this paper, we analyzed how the flickering light based on the waveform of the current changes. This paper is considered to help circuit designers considering the flickering light.
