Definitions

  • the invention relates to an explosion-proof lamp according to the preamble of claim 1.
  • the fluorescent lamps of such explosion-proof lights have a limited lifespan. For this reason, it is necessary to change the fluorescent lamp from time to time.
  • the lamp has two units, namely a power supply unit that is located in a potentially explosive atmosphere (see VDE regulation 0165), whereas the second unit with the light part is plugged into the first unit that contains the power supply unit via connection contacts.
  • the object of the invention is to provide a lamp of the type mentioned, in which the replacement of the fluorescent lamp can be carried out according to the regulations and in which the risk of breakage of the lamps is eliminated.
  • each housing consists of a housing base body and a coupling ring which can be screwed onto it, an elastic seal being provided between the base body and the coupling ring which, after the two have been screwed against one another, lies sealingly against the tube and is pressed against it.
  • the configuration according to the invention virtually forms a cassette in which the fluorescent lamp is located, which can be removed in a simple manner from the connection contacts on the unit containing the power supply unit by being perpendicular to the fluorescent lamp axis or extension from the connection contacts on the power supply unit can be pulled out.
  • the fluorescent lamp remains in the atmosphere inside the tube, which can ensure from the outset that an explosive atmosphere does not surround the fluorescent lamp itself.
  • the fluorescent lamp used is advantageously locked in the assembled state.
  • the coupling rings each have a nose between the base bodies, into which one end of a locking and fixing gear engages in the assembled state.
  • An embodiment of the invention can be such that the locking gear has two rods which can be displaced relative to one another in a manner known per se and which additionally operate a switch for interrupting the power supply. It is possible to use a switch in the supply line to the connection terminals of the lamp, with which the supply line can be interrupted, which switch can be actuated by the actuation of the locking and fixing gear. The switch is expediently switched on during the locking process and switched off during the unlocking process.
  • cylindrical guide bodies made of elastic material, preferably made of foam, can be provided within the tube and are located between it and the inner surface of the tube, surrounding the fluorescent lamp. This also results in an elastic mounting of the fluorescent lamp in the tube, which helps prevent damage to the fluorescent lamp during transport.
  • the tube can be made with reflective material be coated so that the luminance is increased in certain areas of the radiation. In order to then change this radiation characteristic, only the coating of the material needs to be changed. Instead of a coating, a reflective film can also be attached to the inside of the tube.
  • At least one recess is expediently formed on the union ring or the base body, into which the nose engages to fix the tube against twisting.
  • the power supply unit 14 of an explosion-protected lamp 16 is fastened below a ceiling 10 by means of fastening means 12.
  • the explosion-proof lamp 16 has a single-pin fluorescent lamp 18, which is held at its two ends in a housing 20 and 21, respectively.
  • the two housings 20 and 21 are described with reference to the housing 20.
  • the housing 20 has a housing base body 22 which is approximately pot-shaped with a receiving space 24.
  • the free end of the base body 22 ends in a cylindrical collar 26, the outer surface of which has a thread 28.
  • a coupling ring 30 is screwed over the thread 28, a seal 32 being arranged between the bottom surface of the coupling ring 30 and the free edge of the collar 26.
  • the collar 26 On the inner surface, the collar 26 has a shoulder 34 'against which a transparent tube 36 serving as a protective tube strikes with its edge.
  • a contact connection 36 is held, to which the socket 38 for the contact pin 40 of the fluorescent lamp 18 connects.
  • the mounting of the contact 36 in the housing base body 22 and the mounting of the socket 38 are of no further importance for the understanding of the present invention.
  • the fluorescent lamp 18 is held at its end in the region of the coupling ring 30 or the collar 26 with a flexible foam cylinder body 42 serving as a bearing. This cylinder body 42 keeps the fluorescent lamp 18 at a distance from the tube 36 and is also used for shockproof, elastic mounting for the fluorescent lamp 18 in the interior of the tube.
  • a further contact piece 44 is provided which is received in a bore 46.
  • the electrical galvanic connection between the contact body 36 and the socket 44 takes place by means of a flexible line 48.
  • a connection contact element 50 is then located on the power supply unit 14, to which the entire unit or to which the entire unit can be attached in an explosion-protected manner perpendicular to the longitudinal extension of the fluorescent lamp 18 is.
  • the tube 36 is made of transparent, translucent material and, as shown in FIG. 1, can be partially coated with a reflective layer 60.
  • This reflective layer is expediently arranged on the inner surface of the tube 18 and covers a partial segment on the circumference behind the fluorescent lamp 18, wherein the tube 36 can be rotated so that the reflection through the layer 60 can be effected in different directions.
  • the seal 32 which is an elastic seal, is pressed together by the two parts 30 and 22 and pressed inwards against the outer surface of the tube 36.
  • the seal 32 is pressed together by the two parts 30 and 22 and pressed inwards against the outer surface of the tube 36.
  • molded lugs which engage in grooves provided on the base body 22, whereby a security against rotation of the tube 36 is achieved.
  • FIGS. 3 and 4 show two side views of the lamp arrangement according to FIGS. 1 and 2, the lamp arrangement according to FIG. 4 being shown without broken away areas.
  • FIG. 5 It can be seen from FIG. 5 that two lights according to FIGS. 3 and 4 can easily be arranged side by side.
