LED Lighting Design Guide 2015 Littelfuse LED Lighting Design Guide www.littelfuse.com LED Lighting Compliance with Global Standards Many countries are in the midst of developing protection standards for LED lighting. As this lighting technology matures, these requirements in are in a state of flux and may become more stringent. Table 2 is a matrix of current safety and surge standards prevalent in key geographic areas of the world. United States Europe S.

Summary matrix of global protection standards for LED lighting Safety refers to overcurrent protection, particularly short circuit and overload protection. In North America, UL8750 is the Standard for Safety of LED Equipment, which pertains to residential LED lamps and outdoor luminaire assemblies. The purpose of this requirement is to minimize the risk of shock and fire. It calls out the use of an overcurrent protection device to interrupt or limit the current during a short circuit or overload condition. Fuses are the most widely used and reliable protection technology to protect against such conditions. Outside the US, the IEC/EN 61347 LED driver (power supply) specification and IEC/EN 62031 for LED arrays/modules contain safety requirements for these power supplies. In Europe and other countries outside the United States, the surge immunity requirements are referenced in documents such as IEC/EN 61547 that references IEC/EN 61000-4-5, which delineates different surge testing levels based on 8x20s short circuit current combination waveform. For outdoor lighting applications, these levels can range from 4kV/2kA in many Asian countries up to 10kV/5kA in Europe. LED Lighting Compliance with Global Standards 12
