“…The tests executed were performed at LabLux, a laboratory of Federal Fluminense University (UFF-RJ/Brazil); it has INMETRO accreditation to perform conformity tests on lighting products and has a great experience in research related to lighting devices, as reported in several academic documents [13][14][15][16][17][18][19][20]. The laboratory has a shielded room for conducting and radiated EMC tests and a seasoning room to measure LED and fluorescent lamp life.…”
Wi-Fi technology is present in homes, universities, restaurants, and pubs worldwide, thus gaining notorious space in communication systems, especially due to smart technologies improvement. However, several devices can interfere with this network, reducing or even causing data loss on transferences. The Electromagnetic Interference (EMI) caused by lighting equipment is a bad-known and little-analyzed phenomenon in Brazil. The massive use of these technologies needs to be evaluated, remarking a critical analysis of its permitted limits. This study aims to verify and evaluate the possible influences that lighting technologies can generate on communication networks (Wi-Fi) through Electromagnetic Interference (EMI). The following article is the result of several tests under the influence of seven different types of lighting sources among thirteen samples to assess the influence of lighting systems on Wi-Fi networks. The tests were made in a shielded environment, on the LabLux -UFF (Laboratório de Luminotécnica da UFF), using the Iperf3 software.

The Brazilian economic scenario promotes sustainable development by, among other actions, reducing the pressure on the expansion of electricity capacity. Furthermore, efficiency and reliability may be achieved through regulations and standardised production. From this perspective, there is a steadfast need for continuous improvement in the process of certification of products in the country. This shall apply to the energy sector, in which certifications of LED (light-emitting diode) lamps are part of the Brazilian Labelling Program (PBE), coordinated by Inmetro (Brazilian accreditation body). PBE seeks to provide technical information about the products to support consumers’ choices, stimulating industry competitiveness and improve equipment reliability. From this standpoint, this article seeks to present an analysis of the certification process of LED lamps to propose reviewing requirements into the current label which might help to change the consumers’ energy consumption-related decision-making using the multi-criteria decision-making method (MCDM), TOPSIS. To this end, not only energy efficiency was observed but also other aspects of generated light quality and power quality currently considered as requirements for compulsory LED lighting certification.
“…No Brasil, alguns estudos sobre a melhoria da eficiência energética, da qualidade da iluminação e considerando aspectos de qualidade de energia foram realizados, citando-se neste texto alguns de nosso grupo de pesquisa (Oliveira et al, 2018;Pereira et al, 2015;Fassarela et al, 2014).…”

O presente trabalho apresenta um estudo para a melhoria da eficiência energética do sistema de iluminação pública da cidade do Rio de Janeiro através da substituição da tecnologia atual de descarga pela tecnologia LED com uma proposta de controle de dimerização. No primeiro cenário foi analisado apenas a substituição para a tecnologia LED e no segundo foi explorado o potencial da dimerização na melhoria da eficiência energética do sistema. De posse destes cenários, o estudo avaliou os impactos energéticos, econômicos e ambientais.
