Electronica 2012

The 25th International Trade Fair for Electronic Components, Systems and Applications Messe München (November 13 - 16, 2012) 

Littelfuse's Bharat Shenoy, Director of Technical Marketing, will be speaking at electronica 2012 on Wednesday, November 14, 2012 at 10:00 - 10:30 in Hall B5/B5.351


Safety and Surge Immunity Requirements 

for Indoor and Outdoor LED Lighting 


The adoption rate of safety and surge immunity standards such as IEC/EN 62560 and IEC/EN61547 for LED retrofit lamps and other IEC/EN requirements for outdoor and commercial LED lighting is forecasted to grow substantially over the coming years. Businesses and local governments are now requiring electrical protection in their bid packages.

A retrofit LED lamp connected to AC mains can be damaged by short circuit and overload conditions. In addition surges or load switching transients create voltage spikes or ring waves that can stress and damage components.

Outdoor LED luminaires are far more susceptible to lightning induced transients and must contain robust coordinated electrical protection for surge levels as outlined in IEC61000-4-5 and IEC/EN 61643-11. Given that the value proposition for LED lighting is not only lower energy usage, but longer lifetimes, it will be crucial that transient voltage protection is taken into account in addition to safety.
