Intelligent outdoor street lighting

Traditionally street lights were simple timer based solutions, but to further increase efficiency and reduce costs intelligent outdoor street lighting has increasingly becoming the norm. This enables lights to be automatically switched on and off depending on various sensor data - ambient light conditions, approaching vehicles or pedestrians, etc. While high pressure sodium vapor (HPS) lamps can still be found in many industrial and agricultural applications, to further reduce costs street lamps are increasingly switching to LED lamps. In addition street lamps can include functionality such as public WIFI, video surveillance, alarm detection, and 5G base stations.

Highlighted components are Nexperia focus products

Design considerations

  • LED lamps tend to be more efficient that older HPS systems which need an electronic ballast or ignitor
  • LFPAK series of low-voltage MOSFETs together with high-performance CFP Schottky Diodes help deliver high-efficiency DC/DC converter solutions
  • Nexperia's reliable clip-bonding CFP and LFPAK package technology ensure high robustness and outstanding thermal performance
