Análise construtiva e eletroeletrônica de lâmpadas e luminárias LED para interiores

Abstract

This undergraduate dissertation proposes the analysis of commercial models of light bulbs and luminaires that use light emitting diodes (LEDs, from English light emitting diodes) for interior lighting, available in local stores on the present date, in order to subsequently evaluate and compare them. The proposed analysis involves evaluating the overall construction quality of the product (mechanical accommodation, packaging and main connections), determining the accuracy of the information labeled or provided on the manufacturers' websites, identifying the general diagram of the electronic system of interface with the power network and identification of the organization and arrangement of the LEDs of the optical module. Electrical measurements and volumetric analysis are performed, using affordable and low-cost instruments. The evaluations will also survey the possible interventions in the original designs of the manufacturers aiming at the implementation of new functionalities to the products. Some possibilities would be the insertion of visible light communication modules, VLC (visible lighting communication), dimming subsystems, recreational lighting modules (strobe lights linked to ambient music, seasons, hour of the day, or weather), among others. The work developed also aims, through the mechanical and electrical disassembly of the items acquired, to provide subsidies that may contribute to the development of future technical-scientific projects, in view of the difficulty of finding detailed, accessible and comparative information on the main manufacturing methods adopted by the industry. It is important to note that due to the circumstances present at the time of making this work, due to the health emergency condition across the globe, caused by the COVID-19 pandemic, there was a significant difficulty in accessing specialized laboratory equipment (integrating sphere, thermometers and thermal imagers, digital oscilloscopes, watt meters, precision multimeters and others), a fact that limited the achievement of more advanced data and results associated with the study.
