Definitions

  • the invention relates to a lamp according to the preamble of patent claim 1.
  • Such protected lights are known in a wide variety of configurations.
  • the requirements for the degree of protection can vary. There are lights that must be protected against dust and splash water. If the requirements are higher, protection against splash water is no longer sufficient, but the lights must be water-tight.
  • the housing must be more or less tight. If the lamp and thus the housing are heated by the lamp, the pressure rises. If it suddenly cools down, for example due to rainwater, there is an equally sudden decrease in pressure, which can lead to water and dust getting into the interior of the lamp. In the event of a very sudden cooling, the lamp cover glass may even implode. A pressure equalization through a simple hole is not possible with the corresponding requirements for the protection class.
  • the invention is therefore based on the object to provide a luminaire of the type mentioned, which in any case meets the requirements for the corresponding protection type and is in particular protected against the ingress of moisture and dust, without the risk of damage or destruction by there is an implosion.
  • the pressure compensation device is advantageously designed as specified in claims 2 to 5.
  • the arrangement and design of the individual rooms forming the labyrinth and the corresponding connection openings are carried out in such a way that the task of pressure equalization is reliably fulfilled, but that possibly with sucked-in water emerges again from the labyrinth before it reaches the interior of the lamp.
  • a dust filter can be arranged in the area of the transition from the pressure compensation device into the housing in order to prevent even fine dust particles from penetrating into the interior.
  • the pressure compensation device can be designed in a wide variety of ways.
  • the pressure compensation device consists of a main part 1 and a cover 2 fastened thereon.
  • main part 1 two annular spaces 3 and 4 are formed which surround a central space 5.
  • the middle space 5 in turn leads into an opening 6, which establishes the direct connection with the interior of the lamp.
  • the main part 1 is screwed into the indicated housing 12 via a thread 7.
  • a thread 7 Of course, other types of fastening are also conceivable.
  • the annular space 3 is connected to the surroundings via openings 8.
  • the annular spaces 3 and 4 are connected to one another by openings 9.
  • Openings 10 lead from the annular space 4 into the central space 5.
  • the individual openings 8, 9 and 10 are offset from one another.
  • the openings are further arranged and designed so that any water drawn in can emerge from other openings under the influence of gravity.
  • the openings are dimensioned so that the water does not get caught by adhesive forces.
  • the pressure compensation device shown is screwed into a housing, it ensures pressure compensation in both directions.
  • the water sucked in, for example, through an opening 8 can exit again through an opening 8 below.
  • a dust filter 11 sits directly in front of the opening 6 and thus reliably prevents even the smallest dust particles from entering.
  • the two-part design is practically eliminated, since the outer wall of the housing forms the corresponding end wall of the pressure compensation device.
  • the cover can have the different passages of the labyrinth, so that only a simple part for connection to the housing is then attached to this "labyrinth part".
