Effect of the interaction between two led lamps on conducted emission tests


There is a growing global demand for LED lamps and luminaires. This demand inevitably leads to a greater demand for electromagnetic compatibility tests. These tests, for reasons related to the standard that regulates them – CISPR 15 -, are performed individually in each lighting equipment. Still, what can be observed in situations where this equipment is used on a daily basis is the use of two or more units in parallel. As this type of interaction is not foreseen in the standard it is interesting that tests are conducted to investigate if there is indeed any risk in these cases. To this end, conducted emissions tests were conducted to verify how a lamp that exceeds the permitted emission limits has interacted with one that complies with regulatory requirements.
