When contacted, Murata described, from among its numerous noise suppression solutions, its “solutions for suppressing noise in LED lighting,” which have been the subject of an increasing number of inquiries. In regard to noise suppression measures for ensuring compliance with “radiation noise” levels under international standards, which are expected to be enforced in the future, it suggested carrying out various verifications by having prototype products brought to Murata and placed in Murata’s anechoic chamber.
In the anechoic chamber, Murata carried out evaluations and checks for the “noise terminal voltage” that had already been successfully suppressed. This confirmed that there were no problems in this respect, and after ascertaining the characteristics of the LED bulbs made by Company N, Murata instigated measures to ensure compliance with “radiation noise” standards.
As a result, it was found that the design of some circuit components would need to be reviewed and that the standards could be satisfied by using noise filters where they were needed. The required action was achieved with only a slight cost increase.
Teaming up with Murata, a competent partner, paid off, and Company N was able to ascertain how to make the products concerned at a low cost and ahead of schedule. As a consequence and with a higher level of quality added to the results achieved, the company won the competition.
