Evaluation of the Energy Performance in LED Lamps with Integrated Driver through Multicriteria Analysis

Abstract

The lighting industry is having a great change with the advancement of LED technology, allowing the consumer use a more efficient product with longer lifespan, varied colors and shapes. These facts are beneficial to the consumer, but bring with them, a greater difficulty in choosing the product of better energy performance. In this work, a multicriteria analysis will be performed to evaluate the energy performance of LED bulbs with integrated driver in the Brazilian market. In this research, a hybrid multi-criteria approach TOPSIS with entropy weights was used. For this, ten different suppliers  with similar technical characteristics were chosen and the tests required by the Technical Regulation of the Quality in LED lamps with integrated driver, Inmetro Order nº 389/2014 that regulate these product in Brazil were carried out. In addition to the energy efficiency results, the results of energy quality and the quality of the emitted light were also evaluated. Through these analyzes, a ranking was elaborated with the total energetic performance of the evaluated lamps, with the objective of support the end users about the best product, since; there are several technical parameters to be considered
