Energy efficiency in the replacement of fluorescent lamps by led: Application in a store

摘要

This article presents a study carried out in a medium-sized store in the city of Juazeiro do Norte, State of Ceará, where its fluorescent lamps are replaced by Leds. The analysis was performed by comparing yield between the types of lamps and the economy in Kwh generated, savings in real obtained with the substitution, through analyzes and comparisons. Three replacement situations were verified, the first with tubular T5 of 20W and Led of 9W, the second of Tubular T8 of 25W and Led of 10W, the third a general explanation linking the two previous situations to show the total saving of electrical energy Monthly and annual income, respectively. It was also possible to show the cost with energy that each type of lamp generates. According to the data obtained, it is possible to minimize up to 65% of the annual expenses with electricity, obtaining a return of investment of 3.5 months, based on all the studied situations, the study deepens the reduction of electric power for each case, In addition to emphasizing the return on investment and the value that each type of lamp costs.
