  • Luminaire systems for roadways, parking lots and other outdoor or industrial areas typically use plug twist-lock external modules containing different control blocks and/or sensors, e.g. a light sensor for sensing the light level of ambient light to automatically control the light sources of the lighting equipment.
  • electrical receptacles for receiving such external modules are mostly made according to specific standards such as standards approved by American National Standards Institute, Inc. (ANSI).
  • ANSI American National Standards Institute, Inc.
  • Such receptacles are typically mounted in an opening of the luminaire housing and are electrically connected to various components of the luminaire system.
  • the receptacle has a connection interface located on an external side of the housing, so that an external module can be plugged into the receptacle e.g. to provide control for the luminaire system.
  • An external module typically comprises at least three standard prongs or plug contacts which are inserted into corresponding apertures in the receptacle. After the prongs are completely inserted, the external module is rotated to lock it in place. This can be done without tooling, allowing luminaires to be simply and quickly upgraded.
  • the external module may comprise further contacts in the form of conductive springs for cooperating with receptacle contacts in the form of conductive plates.
  • the receptacle and the external module fulfil the requirements of the ANSI C136.10-2017 standard or of the ANSI C136.41-2013 standard or of the Zhaga Interface Specification Standard (Book 18, Edition 1.0, July 2018, see https://www.zhagastandard.org/ data/downloadables/l/0/8/l/book_l 8.pdf).
  • a receptacle When a receptacle is mounted in an opening of a luminaire housing and is electrically connected to components of a luminaire system, the presence of water at an interface between the receptacle and the luminaire housing may perturb the electrical connections between the receptacle and the components of the luminaire system.
