A versatilidade, durabilidade, robustez, eficiência e possibilidade de associação a sistemas de controlo de iluminação, Smart Lighting, para dimerização da intensidade da luz proporcionada pela tecnologia LED tornou-a na fonte de luz mais usada nos dias de hoje. Apesar da aparente menor amplitude de potência, há contribuição harmónica produzida por estes equipamentos, não devendo ser desconsiderada dada a sua influência na qualidade da energia elétrica. Assim, à luz da norma IEC 61000-3-2, analisa-se os conteúdos harmónicos gerados por diversos equipamentos de iluminação em cenários distintos e com a associação de sistemas de dimerização.
The versatility, durability, robustness, efficiency and possibility of association with lighting control systems, Smart Lighting, for dimming the light intensity provided by LED technology has made it the most used light source today. Despite the apparent lower power amplitude, the presence of harmonic contribution by these equipment should not be disregarded given their influence on the electric power quality. Thus, in light of the IEC 61000-3-2 standard, harmonic contents generated by different lighting equipment are analysed in different scenarios and associated with dimming systems.
