Laboratorio de ensayos de iluminación Luminotest

Abstract

This report presents the results of an internship carried out at the Luminotest S.A.S. laboratory, accredited under ISO/IEC 17025:2017, as part of the Electrical Engineering Technology program (Medium and Low Voltage) at Universidad Distrital Francisco José de Caldas. The work consisted of evaluating the conformity of LED lighting equipment against the requirements of Colombia's Technical Regulation for Electrical Installations (RETIE) and the IEC 60598-1 standard, through direct participation in electrical tests (dielectric strength, insulation resistance, protection against electric shock, and tracking), thermal tests (heating, glow-wire, and needle-flame), mechanical tests (IK impact and vibration), and environmental tests (IP protection and corrosion). Recurring nonconformities were identified during the practice, mainly in the glow-wire test at 850 °C and 950 °C, in product labeling and marking, and in insulation resistance values below the required thresholds. The technical analysis showed that electrical safety results from the interaction of multiple factors electrical, thermal, mechanical, and environmental and highlighted the role of laboratory accreditation as the technical and legal backing of product certification processes in Colombia.
