Definitions

  • the invention relates to a recessed luminaire with a square housing, which has a front opening and pairwise parallel side walls and end walls and a rear wall attached thereto and which contains as light bulbs elongated filament with the associated holding means and a ballast, the ballast so resiliently movable on a support element is stored in the housing that at least one outer side of its housing block or the heating components of the ballast with at least one cooling surface is thermally conductive on an outer wall or on the rear wall of the housing or abut, wherein the front opening of the housing through a glass transparency plate or Acrylic glass is tightly closed.
  • Out DE 202 12 411 U1 is a recessed luminaire of the type mentioned above, in which the pairwise parallel longitudinal walls and the end walls of the housing each consist of separate extruded wall profiles, which are interconnected by a bolted back wall. At the corners of the housing, the longitudinal and end walls are each mitred so that they can be joined together without a gap.
  • the back wall on which the bulbs and as in a metal shell molded block formed ballast, consists of a sheet metal part which is screwed from the outside to the longitudinal and end walls.
  • the wall profiles are provided on the back with screw channels.
  • the ballast is usually screwed with its usually only slightly warming bottom with the interposition of an insulating board on the back wall. Effective heat dissipation via the back wall therefore hardly takes place.
  • a light guide or anti-glare screen is arranged in the housing, which rests on support ribs of the housing walls.
  • the translucent lens covering the front opening of the housing is fastened to the glass carrier strips by means of a contiguous adhesive bed.
  • Such recessed lights are usually installed in machine tools, which have in a housing wall in which the recessed light is to be attached, a corresponding rectangular mounting hole.
  • the front sides of the recessed luminaires usually come into contact with chemically aggressive coolants and lubricants. It is therefore essential to hermetically seal the entire housing, so that no aggressive gases and / or liquids can penetrate into the housing interior. Because the currently available adhesives used to attach the translucent lens to the glass support bars are not sufficiently resistant to the aggressive coolants and lubricants, it is also necessary to use the adhesive bed disposed between the translucent glass and the glass support bars. protect against contact with the aggressive coolants, lubricants or gases emitted by them.
  • the invention has for its object to provide a simple and inexpensive to produce recessed light of the type mentioned, in which the housing parts can be assembled both at the initial assembly and subsequent repairs in a simple way by means of simple sealant to a reliable waterproof housing on all sides and at the formation of a caused by electrical components of the ballast heat accumulation within the housing are at least largely prevented.
