Darfon Electronics the turnkey green energy total power solutions provider, new launched a whole series of built-in 10KV lightning surge protected rugged & ultra efficiency outdoor LED lighting driver 60W ~ 270W smart series. To catch the conversion is well under way in many municipalities to convert roadway lighting to solid-state LED streetlight technology. Nowadays rapidly increasing demands for LED-based light sources for outdoor applications bring new challenges to system durability. In order to maximize the durability and reliability of LED lighting systems, it is critical to protect them from damage due to high current surges on the main lines.
Surge damage becomes evident in partial or complete failure of outdoor LED modules
Lightning surge protection is always essential for LED streetlight applications to extend lifetime of LEDs, reduction of maintenance work and replacement costs. A suitable and particularly efficient surge protection concept should be incorporated at the design stage. Although LED technology has a lot of advantages, it has the disadvantage over conventional luminaries technologies that replacement costs for equipment are higher and the surge immunity is lower.
An analysis of surge damage to LED street lights shows that in the majority of cases not individual, but several LED lights are affected. The consequences of damage become evident in partial or complete failure of the LED modules, destruction of the LED drivers, reduced brightness or failure of electronic control systems. Even if the LED light is still operational, surges normally negatively affect its lifetime.
Surge damage becomes evident in partial or complete failure of outdoor LED modules
LED Outdoor Luminaires (Street Lighting, Parking Lot Lighting) IEC/EN 61643-11 IEEE C62.41.2 6kV/3kA 10kV/5kA LED roadway lighting model specification, effective from December 2011, calls out surge immunity requirements for outdoor lighting systems. Model specifications become mandatory ANSI/NEMA requirement. Cities, municipalities and utilities in North America are adopting this model specification in their Requests for Quotes (RFQs) for lighting retrofit projects. North America - Commercial and Industrial Outdoor LED lighting Dept of Energy Surge Requirements with reference to IEEE C.62.41-2002, Europe/Brazil/Asia Outdoor LED Surge Requirement Suggested 10kV/5kA Level Surge Immunity.
