Definitions

  • the invention is based on the DE 195 01 327 C2 known light. Similar luminaires are known DE 102 19 328 A1 . DE 100 10 518 C2 and DE-GM 71 29 201 ,
  • such lamps have a transparent tube of glass or plastic, which is closed on both sides with the open ends of the tube to be used lid parts.
  • a bulb holder usually a support profile, within the tube, the light source, usually a fluorescent lamp, with its sockets and the necessary components for operation, such as ballasts, starters and the like, attached.
  • the protective tube light Since the protective tube light is to be used in damp rooms or under certain circumstances even under water, it depends on a tight closure means of the lid parts crucial. Not unproblematic here is the opening and reclosing of the luminaire when it is connected or when changing the bulb.
  • sealing rings For this purpose, usually equipped with sealing rings two-piece cover are used. With the help of provided on the lid parts Spannkonen the sealing ring is pressed radially outward against the inner wall of the lamp tube when contraction of the cover parts and thus sealed the light.
  • the rotational movement of the lid parts can be transferred to the bulb holder and this turn itself, so that the required positioning of the lamp is not always guaranteed. Also, the electrical leads or their connection contacts can be twisted by frequent twisting and damaged.
  • the present invention the object of the invention to provide a luminaire, which does not have the above-mentioned shortcomings, so that it is easy to assemble and use.
  • a two-part closure cap is proposed with a collar in which a plug part and a coupling part is provided for the electrical connection, which are brought into engagement or disengagement upon rotation of the adjusting ring.
  • a radially expandable sealing ring provides the necessary tightness of the closure.
  • the advantage of the inventively designed lid is that when opening or closing the inventively designed lid by rotating the adjusting ring axial movement of the two lid parts against each other or away from each other is effected, so that connected to these cover parts electrical connector or coupling parts automatically connected or be separated from each other. When removing the lamp so the circuit is automatically interrupted when the lid is opened and removed.
  • the embodiment of the clampable sealing ring is the subject matter of claims 6 and 7.
  • Claim 15 finally refers to the realizable in the cover according to the invention cable bushing, while with claim 16, a more easily actuated for the invention protective tube light in the event of contamination adjustable collar is proposed.
  • FIGS. 1 to 3 are the essential elements of the inventively designed protective tube light illustrated in the assembled state.
  • FIG. 1 lets the lid with lid outer part 60, sealing ring 62, collar 70 and connector part holder 20 recognize.
  • This cover is intended in the in FIG. 1 not shown, but in FIG. 3 partially shown transparent light tube 10 is used.
  • plug member 30 is inserted, which is electrically and mechanically connected to the socket 12.
  • the fluorescent lamp 13 here a single-capped fluorescent lamp, with its base 14 is inserted.
  • the version 12 and possibly other necessary for the operation of the fluorescent lamp components, eg. As ballasts, starters and the like, are mounted on the likewise arranged within the transparent lamp tube 10 bulb holder 11.
  • Openings 22 in the plug part holder 20 allow access to the locking means for the plug 30 and the bulb holder 11th
  • FIG. 3 shows the protective tube light in the assembled state
  • the socket 12 is shown offset with the fluorescent lamp 13 to the right
  • FIG. 4 shows the items of the inserted into the lamp tube 10 lid in detail.
  • FIGS. 5 and 6 The essential for the invention training and operation of the electrical connection with the plug part 30 and the coupling part 40 are based on FIGS. 5 and 6 explained in detail below. While FIG. 5 shows the plug with plug part 30 and coupling part 40 in the open state, goes out FIG. 6 the plug in the closed state.
  • the electrically connected to the fluorescent lamp 13 plug part 30 is inserted into the receptacle 21 of the plug-part holder 20, wherein locking lugs 23 and 24 define the plug in its position.
  • the coupling part 40 Associated with the plug is the coupling part 40, which is secured in a recess 54 of the coupling part holder and with this with spring tongues 53 against axial displacement.
  • the plug part holder 50 is connected to the cover inner part 80 in the axial direction and rotationally fixed, wherein the in FIG. 4 engages more closely represented locking tongues 52 of the coupling part holder 50 in the latching openings 82 of the inner cover part 80.
  • an axial displacement of the inner cover member 80 causes the axial advancement or retraction of the coupling member 40 with respect to the male member 30, whereby the coupling contacts 41 of the coupling member 40 with the contacts 32 of the male member 30 are engaged or disengaged.
  • the axial feed of the cover inner part 80 is the threaded portion 81, with which the rotatable collar 70 with its cam 71 is engaged.
  • the cover inner part 80 with the coupling part 40 of the in FIG. 5 represented uncoupled position in the in FIG. 6 shown coupled position to be advanced, wherein the plug holder 20 with the plug part 30 and the in the FIGS. 5 and 6 not shown bulb holder remain immovable.
  • the electrical contact is made to the fluorescent lamp.
  • By rotating the adjusting ring 70 in the opposite direction of the electrical contact is interrupted.
  • the adjusting ring 70 is held captive but rotatable by means of the lid outer part 60 provided, inwardly directed and engaging in the annular groove 72 lugs 64.
  • the outer cover part 60 is provided at its front end with a sealing ring 62, on the inner cone 65 of the clamping cone 83 of the inner lid portion 80 is applied. Consequently, not only the coupling part 40 is advanced during the axial inward movement of the cover inner part 80, but also at the same time pressed against the inner wall of the light tube 10 under the action of the adjacent cones 83 and 65 of the sealing ring 62.
  • This design allows a relatively large expansion of the sealing ring 62, so that a secure seal is ensured even with comparatively large tolerances of the lamp tube.
  • the inventive construction of the lid thus offers two advantages, namely the interruption of the electrical contact between the power cord and the fluorescent lamp, as well a simple and secure sealing of the lid with respect to the lamp tube with simultaneous contact.
  • the grommet 90 with its screwed onto the threaded tube 93 union nut 91 is conventional in nature and requires no further explanation.
  • the threaded tube 93 is screwed or glued by means of a connecting piece 94 in a corresponding recess 81 a of the inner lid part 80.
  • a provided on the cover-side end locking nut 92 allows for screwed threaded pipe assembly and disassembly by means of a simple open-end wrench.
  • the collar 70 distributed over the circumference blind holes 73, which serve to receive a pin wrench or the like tool to operate better with this collar 70, if it should be resinified or dirty after prolonged use.
  • FIGS. 9 to 11 Another special feature of the adjusting ring 70 is based on FIGS. 9 to 11 explained.
  • the feed of the cover inner part 80 should be recognizably limited in the direction of the light tube for the user recognizable.
  • This purpose is provided by a locking cam 86 and the spring tongue 87 on the threaded portion 81 of the inner cover part 80 latching.
  • the locking cam 86 is dimensioned so that it can be passed clearly visible by the radially evasive cam 71 upon rotation of the adjusting ring 70 for the user.
  • the further rotational movement of the adjusting ring 70 is limited by a radial resilient tongue 87 in the bottom of the thread.
  • this tongue can be run over on further rotation of the adjusting ring 70, whereby the cam 71 reach into the region of these corresponding openings 89 in the inner lid part 80. This makes it possible to deduct the adjusting ring 70 for disassembly over the outer wall 88 of the inner lid part 80.
