Protecting sensitive power supplies, LED drivers, and outdoor LED luminaires is a challenging task. The typical power products used for these applications is not designed to handle the lightning surge transients for highly exposed installations like LED roadway lighting. We will explain the phenomenon of lightning surge and how is leaks into the power circuit and then show optimal protection schemes that will increase the long term reliability of outdoor installations.

Attendees Will Learn:

  • What is lightning surge ; how is it modeled ; what are the relevant standards ; how do you protect against it
  • Optimal protection solutions for surge protection of outdoor applications ; using LED streetlighting as an example.
  • Protection module based solutions and the advantages of specific configurations
  • How to maintain long term reliability of outdoor equipment, specifically LED lighting
  • End-of-life maintenance solutions for external protection modules
