  • the Platinenfixierzunge 12 are still bent to the device carrier 1 and the top of the board 4 to press the board 4 to the mounting side of the device carrier 1, whereby the board is also fixed with respect to the longitudinal direction relative to the device carrier.
  • the device carrier 1 with Platinenfixierzunge 12 and tongues 11 can be particularly preferably made of sheet metal. Because in this case the respective tongues 11 or platinum fixing tongues 12 can be produced in a simple manner by stamping and forming processes.
  • FIG 5 including the Figures 5a , 5b , 5c and 5d a second embodiment of a lamp according to the invention is shown. Similar components are marked with identical reference numbers.
  • Essential difference between the embodiment according to the Figures 1 to 4 and according to the embodiment figure 5 consists in the different design of the adapter 3. While the adapter 3 according to the first, in the Figures 1 to 4 illustrated embodiment is formed in one piece, there is the adapter 3 in the embodiment according to figure 5 from two separate elements 31, 32.
  • the two elements 31, 32 each form an adapter section 30 of the adapter 3 from.
  • Each of the elements 31, 32 has a step-shaped cross section perpendicular to the longitudinal direction X.
  • each of the elements 31, 32 has a first transverse section 312, 322, which rests against the plate 4, and a second transverse section 313, 323, which forms part of the first part of the positive connection and rests on the cover 2.
  • the second transverse section 313, 323 is further spaced along the vertical direction Z from the mounting side of the equipment carrier 1 than the first Transverse section 312, 322.
  • This first transverse section 312, 322 presses vertically from above onto the circuit board 4 in the direction of the mounting side of the device carrier 1.
  • the cover 2 in the exemplary embodiment shown exerts a pressing force upwards on the second transverse section 313 of the separate element 31, which, due to the fixing of the element 31, over the web 314 and the projection arranged thereon on the equipment carrier 1, a contact pressure is exerted vertically downwards on the circuit board 4 by the first transverse section 312.
  • the corresponding function is also in particular in Figure 5b recognizable.
  • the LEDs 41 of the circuit board 4 are located in a transverse section in which the adapter 3 does not overlap the illuminant comprising circuit board 4 and LEDs 41, since the two separate elements 31, 32 are spaced apart from one another by a transverse distance .
  • the illuminant emits light through the cover 2 by means of its LEDs 41 without the light being significantly influenced by the adapter 3 .
  • the inventors have recognized that the provision of such a two-part adapter 3, which does not appreciably influence the light emitted by the light source, is particularly well suited to exerting contact pressure on the circuit board 4 with the adapter. This is because, unlike in the case of optically effective adapters 3, in this case a deformation of the adapter 3 caused by the contact pressure does not lead to undesired optical effects.
