Definitions

  • the present disclosure generally relates to the field of emergency lighting.
  • the present disclosure relates to a lighting fixture for emergency lighting and a related system for operating the lighting fixture.
  • Emergency lighting systems generally have four main operation modes: A normal mode, a rest mode, an emergency mode, and an inhibition mode.
  • the normal mode is generally a state of light-source operation, where the power is received from a normal power supply, such as a main switchboard etc.
  • the rest mode is generally the "off mode", where the lighting is intentionally extinguished.
  • the emergency mode is the state of light-source operation, when the power from the normal power supply is not available for various reasons, such as power failure or maintenance break.
  • the power to the lighting fixture(s) is received from another power supply, such as a conventional battery.
  • the battery may be inside the fixture itself or lie outside the fixture (s) and controlled by an external controller device.
  • the inhibition mode is a state, where the light-source of the lighting fixture inhibits the transition between normal mode and emergency mode, and instead transitions to the rest mode, when the normal supply is turned off.
  • Standard-compliant ways of implementing the operating modes are described, for example, in "Luminaires - Part 2-22: Particular requirements - Luminaires for emergency lighting", IEC 60598-2-22:2021.
  • inhibition mode and rest mode controls are achieved by adding additional cabling to the emergency lighting system, which adds additional work for installing a system with inhibition mode and rest mode.
