The purpose of this study is to investigate the increase of common mode noise due to unbalanced wiring pattern of indoor LED lighting. The common mode current was measured in the cascade wiring model, which was studied by increasing the number of LED bulbs, and in the wiring pattern in which the power line was branched assuming the actual usage environment. A switch line was provided to turn the LED on and off, and the change in current flowing through the power supply line was measured according to the length of the switch line. Cascading and branching increase the current at 100MHz or less because the wiring length is longer in cascaded connection, but current noise increased in the branched range from 100 to 300MHz. When the switch wire was lengthened, the current flowing to the LISN side decreased and the current to the LED1 side increased. As a result of measuring the current distribution on the switch line, the current is large on the LED side and decreases when approaching the switch. |
