Definitions

  • the invention relates to a recessed light.
  • Recessed lights are known in various forms, for example in residential construction, but also for swimming pools, whirlpools or the like.
  • the invention is directed to a recessed luminaire with a halogen lamp arranged therein, which can be detachably inserted into a socket, the halogen lamp being covered by a glass attached to the housing and / or the socket.
  • a major problem of the generic recessed luminaires with halogen lamps is the high heat generated by the halogen lamp, which can lead to heat accumulation below the cover glass and, in extreme cases, to the destruction of the luminaire.
  • the difficulty of heat dissipation increases, the smaller the design of the recessed luminaire, because the space between the halogen lamp and the cover glass or the housing and the area of the cover glass suitable for heat dissipation is correspondingly reduced.
  • the invention is based on the object of offering a recessed luminaire, in particular for swimming pools, whirlpools or the like, which enables improved heat dissipation compared to known embodiments.
  • the aim is to keep the design of the luminaire as small as possible without neglecting the technical safety requirements of halogen luminaires.
  • This includes, for example, when used as a swimming pool headlight, the watertightness and generally the request to permanently attach electrical connection cables for the consumer within the housing to the socket for the halogen lamp.
  • the invention is based on the finding that an increase in the heat transfer surface can be achieved despite the reduced design in that the front glass is drawn into the housing at a distance from the inner wall, thereby forming a type of open annular channel into the air or water Cooling / heat dissipation can flow.
  • the invention relates in its most general embodiment to a recessed luminaire, in particular for swimming pools, whirlpools or the like, with an outer housing, a halogen lamp arranged therein, which can be detachably inserted into a socket, and one which overlaps the halogen lamp at least at its free end and detachable from the housing and / or the socket, but sealed from the surroundings in the mounting position, in which the housing and the front glass are formed such that partial sections face each other directly but at a distance and between the corresponding outer surface of the front glass and the corresponding one Inner surface of the housing formed space to the light exit end of the lamp is open.
  • the partial sections mentioned are cylindrical.
  • an annular gap is then formed between the housing and the front glass, through which water can flow, because it is open in the direction of the liquid in the swimming pool. In this way, the coolant (water) is continuously fed.
  • the front glass can be attached in a particularly simple manner at its open, lower end via a seal in a gas-tight and water-tight manner with respect to the corresponding inner wall of the housing.
  • This embodiment has the further advantage that the front glass is practically fixed only to static friction relative to the housing, so that it can be easily removed at any time, for example to replace the halogen lamp.
  • a seal in the form of an O-ring is arranged between the front glass and the corresponding housing section.
  • a groove for partially receiving the seal can be provided in one of the corresponding surface sections of the front glass or the housing.
  • a recessed luminaire in which the halogen lamp is at least partially surrounded by a reflector which widens in the direction of the light exit end of the luminaire and is at least at its free end a short distance from the front glass or bears against it.
  • a further improvement in heat dissipation can be achieved by creating a more or less continuous thermal bridge from the halogen lamp to the cover glass via the reflector.
  • the lamp is designed so that the halogen lamp is in flat contact with the reflector or directly next to it and the reflector itself lies directly against the inner wall or the free end of the cover glass or runs in its immediate vicinity.
  • the reflector is usually made of metal, it is particularly suitable for dissipating the heat from the inside to the outside.
  • the reflector bears at its open, free end against the inner wall of the front glass.
  • the reflector is preferably formed with a small cylindrical area, so that not only a linear but also a flat contact with the inner wall of the front glass is produced.
  • the positioning of the reflector itself is preferably carried out in a cylindrical receptacle which is itself attached to the socket for the halogen lamp or to the housing.
  • Both the receptacle and the reflector preferably have a circular cross section, the reflector, starting from the holder, preferably first of all having a cylindrical section which bears against the halogen lamp and which is then adjoined by an expanded reflector section.
  • This can be hemispherical, for example.
  • an advantageous embodiment of the invention proposes to arrange the reflector in a height-adjustable manner along the receptacle.
  • Various embodiments are available to the person skilled in the art for this purpose.
  • the connection of the receptacle and the reflector by means of a bayonet catch is an example.
  • a further embodiment of the invention proposes to design the luminaire with a second reflector which, in the direction of the light exit end, is arranged in an extension of the first reflector on the inner wall of the housing. Doing so - viewed in the axial direction of the lamp - the upper free end of the first reflector and the lower free end of the second reflector overlap over a certain section to ensure that scattered radiation is also completely reflected.
  • This embodiment has the important advantage that no disturbing reflections occur in the field of view of the user due to the "double reflector design", even if the user looks directly into the spotlight. Due to the intersecting beams, the user may perceive a dark point.
  • the second reflector can be positioned from the outside by simply attaching / plugging it onto the free end of the housing.
  • the second reflector can also be retrofitted. The following exemplary embodiment illustrates this embodiment in detail.
  • the socket for the halogen lamp be attached to the housing.
  • a further alternative embodiment provides for the socket at the lower receiving end for the electrical connection cable to be formed with a cylindrical receiving part which has one or more latching projections on the inside, which are in the assembled state protrude from the socket in the sheath of the connection cable.
  • the receiving part of the socket is designed so that the locking projections clamp the sheath of the electrical connection cable in the assembled state.
  • the receiving part tapers circumferentially towards the free lower end and the housing is formed in this area with a corresponding opening, the cross section of which, however, is at least at the lower end smaller than the corresponding cross section of the receiving part. This leads to the fact that when the socket is inserted into the opening of the housing, the receiving part is pressed inward, which at the same time pushes the locking projections into the cable sheathing and thus fixes it.
  • the receiving part must consist of a deformable material.
  • various plastics are available to the person skilled in the art, for example, which simultaneously have electrical insulating properties.
  • An additional seal can be used to seal the luminaire to the outside via the cable connection.
  • the inventive design of the recessed luminaire makes it possible to design it in a particularly small size without the risk that the heat generated can no longer be dissipated.
  • Embodiments with a maximum diameter of less than 70 mm are easily possible.
  • the single figure shows a recessed luminaire according to the invention, partially in longitudinal section, which is inserted into the wall of a whirlpool.
  • the recessed luminaire has a pot-shaped, cylindrical housing 10, which at the upper free end is bent outwards and with the protruding edge section 10a surrounds the opening 14 provided in the wall 12 of the whirl pool (not shown in the rest) and is fixed in the region of the opening 14 by means of a holder 16.
  • the cylindrical wall section 10b there is a materially thickened, conically tapering section 10c, which in the middle has an opening 18 which tapers conically towards the lower end and which serves to receive a receiving part 20 of a socket 22, which in turn is used for releasable recording of a halogen lamp 24 is provided.
  • the receiving part 20 also has a cylindrical shape. While the inner opening is largely cylindrical, the outer circumference is tapered towards the lower end, whereby - in the unmounted state - the outer diameter of the receiving part 20 at the lower end is slightly larger than the inner diameter of the opening 18 in the housing part 10c at the corresponding point in assembled condition.
  • the latter - like the housing 10 - is made of plastic.
  • the socket 22 is fastened to the housing part 10c by means of screws 30.
  • the screws 30 are arranged at an angle of 120 degrees to one another. At the same time, they fix the horizontally running edge 32a of an otherwise cylindrical receptacle 32 for a reflector 34 for the halogen lamp 24.
  • the reflector 34 has a cylindrical lower part 34a, which has two diametrically opposite projecting knobs on the outside in the lower part, which lie in corresponding, thread-shaped grooves in the inner surface of the receptacle 32, and thus a vertical displacement of the reflector 34 along in the manner of a bayonet lock enable the cylindrical receptacle 32.
  • the cylindrical section 34a is followed by a hemispherical further section 34b, the upper free end of which is again approximately cylindrical and bears against the cylindrical inner surface 36a of a front glass 36 covering the halogen lamp 24.
  • the front or cover glass 36 has a pot shape that is inverted relative to the housing 10, so that the open free end projects into the housing 10.
  • the cover glass 36 is approximately half as high / long as the housing 10.
  • the cover glass 36 has an annular groove 38 on the circumferential side, in which a seal 40 partially lies, which seals the glass 36 against the inner wall of the housing 10 and it stipulates there at the same time about static friction
  • To prevent the glass 36 from slipping the housing wall is formed on the inside with an annular projection 42.
  • the glass 36 with the seal 40 lying in it can be guided past the projection 42 by squeezing the seal 40; then the projection 42 ensures that an unintentional detachment of the glass 36 from the housing 10 is prevented.
  • the figure further shows that there is a distance between the cylindrical outer surface 36b of the cover glass 36 and the corresponding cylindrical inner surface of the housing 10, through which a cavity 44 is formed which is open towards the front (towards the light exit end).
  • the vertical section of a second reflector 46 also extends into the space 44 and is guided around the part 10a of the housing 10 and bears against the outer surface of the wall 12. It can be retrofitted by simply placing it on the corresponding housing section 10, 10a and thus lengthening the reflector 34 in the direction of the end on the light exit side.
  • the highest temperatures are reached in the area of the socket 22 or the halogen lamp 24.
  • the heat is transferred directly to the highly heat-conducting reflector 34, from there again by means of surface contact to the front glass 36, which is continuously rinsed with cold water in the area of the room 44, but of course also in the area of the front plate 36c when used in the whirlpool that ensures appropriate heat dissipation.
  • the space 44 enables the arrangement of a further reflector, so that, despite the miniaturized design, a significantly improved heat dissipation and, at the same time, excellent lighting quality can be achieved.
