CONDUTA ECOLÓGICA E EFICIÊNCIA ENERGÉTICA FAZEM DO LED A LUZ DO FUTURO

Abstract

Humans have struggled for long to master and save light, while obsessed for beating darkness. The human kind experienced from fire to electric lamps, varying materials, sizes and light intensities – always aiming at a common goal: light serving man. Technologies have evolved remarkably, currently providing excellent lighting – e.g., fluorescent light bulbs, widely used, since they consume little energy and simulate daylight. However, they use mercury (a toxic element) inside – so, their growing consumption, combined to inadequate disposal, yields new concerns. The paper contributes to show the environmental harmfulness of fluorescent lamps – thus, affecting humans – and presents most acceptable alternatives for replacing them. Current technologies permit to change from fluorescent lamps to LED lamps, which allow for considerably higher sustainability levels, bearing several benefits and advantages as compared to fluorescent lamps. A feasibility study, here, focus on school environments, understood as an ideal site to promote true environmental awareness.
