研究目的
To evaluate the energy performance of LED bulbs with integrated driver in the Brazilian market using a multicriteria analysis approach.
研究成果
The multicriteria analysis provided a comprehensive evaluation of LED lamps, considering not only energy efficiency but also energy quality and light quality. The best-performing lamp achieved high scores across all parameters, demonstrating the importance of a holistic approach to evaluating LED lamp performance. This methodology could be beneficial for regulatory bodies in improving product evaluation and classification methods.
研究不足
The study focuses on LED lamps available in the Brazilian market and follows the specific regulations and standards applicable in Brazil. The multicriteria analysis may not capture all subjective preferences of end users.
1:Experimental Design and Method Selection:
A hybrid multi-criteria approach TOPSIS with entropy weights was used to evaluate the energy performance of LED bulbs.
2:Sample Selection and Data Sources:
Ten different suppliers with similar technical characteristics were chosen. The tests required by the Technical Regulation of the Quality in LED lamps with integrated driver, Inmetro Order no 389/2014, were carried out.
3:List of Experimental Equipment and Materials:
Not specified.
4:Experimental Procedures and Operational Workflow:
Tests were performed in the Luminotécnica Laboratory of the Universidade Federal Fluminense (LABLUX), accredited by Inmetro for LED lamp testing. The tests included measurements of energy efficiency, energy quality, and light quality.
5:Data Analysis Methods:
The TOPSIS method was applied to rank the lamps based on their total energy performance.
