Spectroscopic and Oscilloscopic Studies of Commercial LED Bulbs and Their Flickering Measurements
The emission of Ultraviolet radiation and flickering effects are investigated in commercial LED lightings by performing spectroscopic measurement and oscilloscopic study on different LED bulbs. The driver circuits of these bulbs are also investigated for their performance. It is observed that basic rectifier and resistor networks are used in cheap local LED lamps, causing perilous effect and creates fluctuations. This paper is putting light on the path for providing standard tests for efficient lighting system.
