Definitions

  • the present invention relates to a luminaire, preferably emergency luminaire, with an indicator and an antenna as well as to a lighting system comprising at least such a luminaire.
  • a luminaire, such as an emergency luminaire, with one or more lighting means for light emission may comprise an indicator comprising one or more indicator lighting means for indicating by light emission information, such as the status of the luminaire, to the outside of the luminaire. Therefore, the indicator of the luminaire is arranged such that its light emission is visible to the outside of the housing of the luminaire and, thus, to the outside of the luminaire.
  • An emergency luminaire is a luminaire configured to emit light in an emergency case, such as mains failure, from an electrical energy storage, such as a battery.
  • the energy storage e.g. battery, may be rechargeable.
  • such an indicator may be mandatory in order to inform a user about the functionality of the emergency luminaire via the indicator, in particular via the light emission by the indicator.
  • the luminaire is configured for a wireless communication using an antenna for transmitting and receiving electromagnetic waves.
  • the luminaire comprises such an antenna within its housing, which is usually made of material preventing or damping electromagnetic waves, such as metals, the antenna may be shielded by the housing and, thus, the wireless communication by the antenna may be disturbed or even not be possible.
  • Providing an opening in the housing at the place (location) of the antenna for overcoming the problem of the antenna shielded by the housing has the disadvantage of reducing the protection offered by the housing against ingress of solid objects, such as dust, ingress of liquids, such as water, and accidental contact.
  • This protection is classified by the IP code (also referred to as “International Protection Rating’’ or “Ingress Protection Rating’’) and may be referred to as IP protection.

Since the indicator has to be visible to the outside of the luminaire and, thus, to the outside of the housing of the luminaire, the antenna arranged together with the indicator of the luminaire is not shielded by the housing of the luminaire. Therefore, the housing of the luminaire does not disturb the wireless communication by the antenna with the outside of the luminaire.
  • the invention proposes to arrange the antenna at the place of the indicator, i.e. to arrange the antenna together with the indicator at least partly in the opening of the housing for the indicator.
