Study on Noise Distribution Generated from Multiple LED Lights Installed on Duct Rail

The radiation noise from LED lights in the simultaneous use of multiple LED lights is not a simple linear increase with respect to the number of LED lights. The amount of increase in radiation noise becomes more complex with frequency as the number of LED lights increases. To clarify the radiation noise characteristics from multiple LED lights, a radiation model was simulated when multiple LED lights were connected to the same power line. In this study, the change in noise distribution on the power line depending on the installation position of multiple LED lights was investigated to clarify the relationship between the radiation noise and LED lights on the power line.
