Surge Protection Device for Led Street Lightings, LED technology has become the reference technology for lighting, mainly because of four characteristics: efficiency, versatility, energy savings and longer life. In spite of these benefits, the technology has a number of drawbacks: Higher cost of implementation (initial investment) and internal electronics (LED optics and drivers), much more complex and sensitive to overvoltages than in the case of traditional light sources.
