Definitions

  • Such night-lights are known and are used mainly in stair-wells and childrens bedrooms where they serve as a point of orientation and/or serve to distinguish the contours of objects present near the night-light.
  • Such a night-light can be provided directly on a wall socket.
  • a favourable embodiment of the night-light according to the innovation is characterized in that the tube is secured to the cap so as to be rotatable.
  • the night-light may also be used in a bedroom in which a wall socket is located in an unfavourable location relative to the bed because the illuminated part of the envelope can be blanked out by rotation.
  • the glow-discharge lamp may be a neon lamp emitting red light as well as a lamp emitting a green light and containing a gas and mercury and of which the wall of the envelope is covered with a fluoresent layer.
