Definitions

  • the invention relates to a built-in luminaire according to the preamble of claim 1.
  • Such built-in lights are primarily used as indirect lighting in furniture, with the light body fitted with LEDs as light sources being inserted into a recess on the underside of a furniture panel. On the visible side, the luminaire body is covered by a connected panel.
  • the power line is routed through a core hole provided in the furniture panel to an electrical supply unit, for example a transformer, which is often located behind the rear wall of the furniture.
  • an electrical supply unit for example a transformer
  • the core hole is guided from a narrow rear side of the furniture panel to the recess receiving the lighting element, the power line having to be routed into the core hole before the lamp is inserted, which, however, makes assembly of the furniture panel significantly more difficult.
  • a recessed luminaire is disclosed, with LEDs that are held in a housing.
  • contact elements are arranged in the housing, into which a current conductor is inserted with its stripped end and is held in a clamping manner. The problem described above also arises with this known built-in lamp.
  • a comparable recessed luminaire is from the DE 20 2015 106378 U1 known.
  • the conductor of this recessed luminaire is positively held in the luminaire body.
  • a spring terminal connection deviating from this type is in the DE 10 2015 115 425 A1 thematized.
  • This spring clamp connection has a receiving cage with a spring leg and a contact plate, between which the stripped end of a conductor is clamped.
  • the US 2011/021061 A1 thematizes an electrical plug connection, in which electrical contacts connected to an electrical conductor are arranged on an insulating carrier plate, the carrier plate being inserted into a contact receptacle, with contacting of contact elements.
  • a lamp is known, in particular for a motor vehicle, whose power supply also takes place via a plug connection, an extension connected to a lamp part with contact strips corresponding to contact elements of a counterpart which is connected to a power line.
  • the invention is based on the object of further developing a recessed luminaire of the generic type in such a way that it can be used while maintaining the built-in luminaire State optimized design is easier and therefore cheaper to assemble.
  • the connection of the luminaire body to the conductor is now possible transversely to its longitudinal extension, i.e. in the direction of insertion of the built-in luminaire into the recess of the furniture panel.
  • the conductor is positioned in such a way that the connection with the built-in lamp takes place immediately when it is inserted or pressed into the recess.
  • the end of the conductor facing the built-in lamp is provided with a contact plate, which is frictionally held in it after connecting the lamp body, ie after it has been plugged on, for which purpose the lamp body preferably has resilient contact clamps resting on the contact plate of the current conductor on both sides, which are part of a Are making contact.
  • the contact plate For easier introduction of the contact plate into the contact receptacle of the luminaire body, according to a further concept of the invention, at least in the pushing-on direction transverse to the longitudinal extension of the conductor, it can be provided with insertion bevels, which can be formed by appropriate shaping of the contact terminals.
  • lead-in bevels in the simplest case a single lead-in bevel, can be provided on the outer edge area of the contact receptacle, whereby when two lead-in bevels are arranged, these are V-shaped to each other and merge into an introduction slot for receiving the contact plate.
  • the contact clamps which face each other as flat contacts and thus form an insertion slot - both in the longitudinal extension of the conductor as well as transversely to it - can be applied directly to an LED board if the built-in lamp is designed as an LED lamp.
  • the LED board can be equipped with a rectifier bridge for a non-polarized line connection.
  • an insulator piece is fixed in the luminaire body, which receives the contact clamps.
  • the conductor is provided with a rigid support at least in some areas, preferably in the area associated with the contact plate, which significantly simplifies the introduction of the contact plate into the contact receptacle of the lamp body.
  • the current conductor can be dimensioned particularly small in cross-section in this way, so that the diameter of the core bore can be minimized accordingly.
  • centering means are provided on the conductor, which ensure radial alignment within the core bore.
  • An exact positioning of the conductor in the core bore can be done by a rotation angle coding, which also forms an insertion aid, for which purpose a nose can be formed on one end of the conductor or the rigid area, in particular on a provided strain relief, which can be inserted into one of the Core bore provided longitudinal slot engages so that a rotation lock is formed.
  • the rigid area extends into the rear insertion area.
  • the contact conductor protrudes with a connection tab, which is also designed as a contact plate and onto which a plug connected to a cable can be plugged.
  • the connection lug can have a recess into which the rear wall of the piece of furniture is inserted, creating a restriction for the electrical conductor to be pushed in.
  • the plug can have a cable connector which is connected to a rigid rod in a current-carrying manner and which rests on the outside of the rear wall.
  • such an insertion limitation can also be achieved in that the plug is firmly connected to the connection lug before the conductor is inserted into the core hole, with the plug or the connected rod then with the cable connector on the rear panel.
  • a cable can be connected to the plug, preferably with a holder with which the looped cable is kept in an orderly manner until it is connected to a power supply unit.
  • the current conductor can also be firmly positioned in a holder which is inserted into a receptacle in the furniture floor, preferably adjacent to the lamp body, wherein this holder can be pot-shaped or cuboid.
  • the flexible part of the current conductor which emerges from the holder on the side facing away from the lamp body, is guided along a groove in the furniture base, which can optionally be closed by a cover strip.
  • a cover strip In the case of the cuboid design of the holder mentioned, it can also be positioned in the groove, adjacent to the lamp body.
  • a built-in lamp is shown, which can be built into a furniture panel 11 ( Figures 3 and 4).
  • the built-in lamp has a lamp body 2 to which a current conductor 1 is connected.
  • the luminaire body 2 is covered by a cover 14 resting on the furniture panel 11 on the visible side.
  • the conductor 1 has, at least at its end facing the lamp body 2, a contact plate 3 which is held in a contact receptacle 4 of the lamp body 2 in a frictionally engaged manner.
  • two opposing resilient contact terminals 5 provided with contact surfaces are provided in the luminaire body 2, which delimit a slot open in the direction of extension of the conductor 1 and transversely thereto, through which the contact plate 3 can be inserted into the contact receptacle 4.
  • the contact terminals can be arranged on a circuit board of the lamp body 2.
  • the conductor 1 is in the in the Figures 1 , 2 , 4th , 6th and 7th
  • the examples shown are supported over its entire length by a rigid area 6, for which the current conduction is embedded in a corresponding material, in particular in a printed circuit board.
  • the conductor 1 is shown as a detail, the end of the conductor 1 facing away from the contact plate 3 can be connected to a transformer, not shown, via a contact receptacle 9 and a cable connector 10 connected to a cable 8.
  • the associated end of the conductor 1 can be provided with a contact plate for contacting, onto which the contact receptacle 9 can be pushed.
  • the Figure 4 very clearly shows the lamp body 2 pushed in, while the conductor 1 with its rigid area 6 is guided in the core bore 12.
  • a radial support 7 is provided at both ends of the rigid area 6, the largest diameter of which corresponds to the clear diameter of the core bore 12.
  • This radial support 7 can moreover be provided, for example, with an integrally formed nose which, for the exact alignment of the conductor 1, engages in a slot (not shown) in the core bore 12 and thus forms a rotation angle limitation.
  • the radial support 7 facing away from the contact plate 3 can also be designed as a strain relief.
  • a lamp body 2 is shown as a detail.
  • an insertion aid 15 is provided which has two insertion bevels 16, both of which merge into a slot 17. This enables the lamp body 2 to be particularly easily plugged onto the contact plate 3 of the conductor 1, while at the same time aligning the lamp body 2 and the panel 14, which may be connected to it, precisely.
  • the design of the built-in lamp for feeding current into the conductor 1 is shown.
  • the current conductor 1 is guided with its rigid area 6 to the rear of the furniture, which is formed by a rear wall 18.
  • a connection lug 19 firmly connected to the conductor 1 protrudes outwardly beyond the rear wall 18, with a plug 21, which is an angled, rigid and current-carrying connector Has rod 22, is slipped onto the connection tab 19.
  • the plug 21 can be seen in an exploded view.
  • a recess 20 in the connection lug 19 accommodates the associated edge area of the rear wall 18, so that the conductor 1 is held in a manner that is secured against displacement and is precisely positioned.
  • the rear wall 18 can also be provided with a corresponding notch through which the connection tab 19 passes.
  • the conductor 1, together with the plug 21 and the rod 22, to which a cable connector 10 is connected can already be firmly connected to the connection lug 19 before assembly, or the rod 22 is located after the conductor 1 and the rod have been inserted connected plug 21 to the already mounted rear wall 18, which also creates a push-in limit.
  • a comparable variant is in the Figure 7 recognizable, although here a flexible cable 8 is connected to the plug 21.
  • a cable holder 23 is provided on the latter, which holds the cable 8 laid in loops in an orderly manner.
  • the conductor 1 can also be provided with a contact plate 3, while the plug 21 is configured accordingly, i.e. with a contact which is connected to the cable 8.
