Definitions

  • Explosion-proof lights have higher requirements are sufficient than usual in the industrial or household sector used lights.
  • a housing needed in which the illuminant in the form of fluorescent lamps are accommodated. This housing may only then be opened when the socket contacts with certainty are without tension. That's why there is one in the housings contain relatively complex mechanism that the Locking the housing mechanically with a switch couples to de-energize the lamp holders, as soon as the housing is to be opened.
  • a lamp of this type is for example in DE-C-39 11 901.
  • the lamp housing is there from two long tubs, according to the length of the fluorescent tubes to be accommodated.
  • a mounting plate attached that doubles as a reflector serves for the illuminant.
  • On this mounting plate sit u.a. the ballasts and the connection clamps.
  • This consists in the installation of the ceiling adjacent tub from an opaque extruded profile, on the End pieces are attached.
  • the second tub is there made of a translucent material and is congruent on the edge of the top tub. Both tub are hinged together.
  • In the closed Position is the housing with slide Hooks that are longitudinally displaceable in the upper tub are led.
  • the length of the sealing surface is relatively very large and it's not easy to ensure the necessary sealing.
  • the plastic material the housing tends to be in the area between the hook-shaped closures slightly through the seal to be deformed so that over time the contact pressure subsides.
  • the housing of the new lamp essentially consists from a housing tube that is translucent at least on one side is. Are on both ends of the casing tube Lid attached. Because of this design, they are limited the necessary seals on the axial annular gap, between the housing tube end and the cover. The length of the Annular gap is relative to the size of the lamp very small and therefore easy to seal.
  • the strength and stability of the Gap geometry high because the housing tube through the seal is loaded in the longitudinal direction and do not dodge can, while the lid is easily stable enough can be designed in the area of the sealing rebate. About that In addition, it is even possible to end up on one To do without the seal, in which the lid immediately with the housing pipe is cohesively connected.
  • the new design makes it possible to build a luminaire which is at least splashproof. You can even seal so far that it can also be submerged.
  • the desk is coupled with the locking mechanism and provides for switching off the voltage at the ballast and thus also on the lamp holders when the cover is opened becomes.
  • a particularly great strength and security against Deformation is achieved when the body tube is essentially is cylindrical.
  • the housing of the new lamp can be particularly inexpensive establish if the casing tube is a section an extruded profile.
  • the support plate is held with the tie rods, so that no additional holding links on the housing tube or the covers are required.
  • the mounting plate can also be a section of a Extruded profile as well as this for the reflector applies.
  • a mounting plate which sits on the other side of the support plate like that Reflector.
  • the attachment of this mounting plate to the Carrier plate can be done in a similar way as the connection between the reflector and the support plate.
  • the Switch coupled to the locking device in such a way that when the locking device is in the open position is transferred, the switch inevitably in the OFF position brought.
  • a very simple locking device is in one rotatably mounted in the cover or the intermediate piece Shaft to be operated from the outside and a cam that cooperates with the switch.
  • the locking device can have a hook, which cooperates with the abutment and the cover pulls against the adapter.
  • Replacing the lamp is particularly easy if the reflector is provided with connectors that with other lamp-proof connectors that work together in turn when pulling out the reflector in the lamp remain. These other connectors are more convenient Way arranged on the mounting plate, which is also the ballast wearing.
