  • the contact body K12 has a mounting structure B12 which cooperates with the opening L12 of the circuit board PL2 in order to connect the contact body K12 mechanically and preferably also electrically at the same time to the circuit board PL2.
  • a connection is preferably provided by a riveting, but such a connection can also be done in other ways.
  • the contact body K12 in the connection via the opening L12 and the mounting structure B12 is pivotable relative to the board PL2 transverse to the central longitudinal axis of the arrangement.
  • a contact tab BK11 for contacting one of the battery terminals of a battery BA is formed.
  • a second contact tab BK12 for contacting the other pole of the battery BA is formed on its side facing in the longitudinal direction of the circuit board PL2 side.
  • brackets KL2 formed which comprise the battery BA in the assembled state over an angular range of more than 180 ° and bear resilient projection on the jacket of the battery. In the circumferential direction, the brackets KL1 and KL2 extend only so far that a mutual electrical insulation of the contact body is ensured.
  • a bracket-like ring structure KR is formed, which can serve to make a clamping connection of the insert assembly with the extension body FO, for example, the cylindrical portion FZ of the extension body FO has an inner wall, in which the ring structure KR can be used under radial stress.
  • the insert assembly can be handled uniformly together with the extension body FO.
  • the extension body FO in turn shows a flame body FK for a battery-operated candle as a luminaire arrangement and in the example sketched in FIG. 7 an approximately conically extending towards the flame body plate section FV.
  • the contact body K11 is mechanically and electrically connected via the attachment structure B11 in cooperation with the aperture L11 and the contact body K12 is connected via the attachment structure B12 in cooperation with the aperture L12 in the board, the contact body K12 relative remains pivotable to the board.
  • the battery BA is preferably first attached to the contact body K12 by the battery over the brackets KL2 snapped across the longitudinal extent of the contact body or inserted in the longitudinal direction of the contact body KL12 through the brackets KL2. Thereafter, the contact body K12 together with the battery is pivoted about the connection between the mounting structure B12 and the opening L12 in the direction of the first contact body, wherein the brackets KL1 are bent resiliently by the battery body and in the sketched in Fig.
  • the insert assembly thus again forms a self-contained and the individual components self-holding assembly, which can be handled uniformly for the further assembly process.
  • the preassembled insert assembly EZK, the sleeve HU of the main body and the extension body FO are assembled in the longitudinal direction of the central longitudinal axis ML to form the finished luminaire arrangement.
  • the special ease of installation results from the separate pre-assembly of the individual components of the insert assembly EZK to a self-holding assembly and the simple further composition of sleeve, insert assembly and extension body.
  • the luminaire arrangement for a replacement of a defective battery can be easily dismantled by the user himself, as indicated in FIG. 9.
  • the insert body FO is removed from the sleeve HU, wherein in the example sketched with the described clamping connection between the ring structure KR and the cylindrical portion FZ of the extension body FO at the same time a removal of the insert assembly is connected from the sleeve.
  • the extension body FO and the insert assembly EZK can be removed one after the other from the sleeve.
  • FIG. 10 shows two sectional views of a fully assembled battery operated candle with components corresponding to FIG. 7 to FIG. 9 in two mutually perpendicular sectional planes through the central longitudinal axis, wherein in FIG. 10 (A) the sectional plane A - A is vertical and in FIG 10 (B) the section plane B-B is parallel to the plane of the circuit board PL2.
  • the light-emitting diode LED is coupled to the flame body FK in that the potting body of the light-emitting diode LED itself has a surface acting as a concentrating lens, the flame body FK facing and the light bundling is thus primarily through this surface of the potting of the light emitting diode.
  • the features indicated above and in the claims, as well as the features which can be seen in the figures, can be implemented advantageously both individually and in various combinations.
  • the invention is not limited to the described embodiments, but within the scope of expert Can be modified in many ways.
  • the realization of the light entry surface in the form of a lens surface at the base of the flame body can also be implemented advantageously independently of the other construction features.
  • the extension body can also be connected to the sleeve and / or to the insert body in other ways, in particular via a thread arrangement.
