TECHNICAL ANALYSIS ON REPAIR OF LED TORCHLIGHT

LED torchlights are used in Nigeria as lighting devices. Its components constitute electronic waste and environmental hazard. Hence, there is a need to repair them to elongate their usage period and reduce electronic waste. To enhance repair process, this research was carried out to determine common faults of this device, the cause of the fault and components that technicians need to be stock to ease replacement bad components. Forty samples of faulty LED torchlights were collected from their respectful users while preventing the users from throwing them to refuse dumps. They were diagnosed, identified the cause of the faults and repaired. An hundred percent (100%) success was recorded. Empirical analysis of the faults through repair showed the least and most common faults of the LED switch and the components that must be stocked. Various causes and preventions of the faults were discussed.
