LED driver potting

LED drivers are electronic circuits that convert input voltage (mains grid 127V/220V) to voltage and current suitable for LEDs (typically 24V-48V at specific currents), controlling luminaire operation. In outdoor applications (street lighting, industrial, external architectural, stadiums, tunnels, parking lots), drivers are subjected to severe conditions: ambient temperature from −30°C to +55°C, variable humidity, rain, dust, salt spray in coastal regions, vibration (applications such as bridge lighting). Total driver encapsulation with PU potting is standard in premium outdoor drivers — it protects all electronic components, provides IP67 or IP68 protection class, and works as a thermal dissipator for power components. Difference between driver with quality potting vs. without potting: service life of 50,000-100,000 hours vs. 10,000-20,000 hours, respectively.
