  • connection device 60 corresponds to an associated connection device 61 of the mounting rail or is connected to it to provide the respective electrical supply to the two printed circuit boards 15 equipped with LEDs
  • Figure 7 the two optical covers for the direct light component and the indirect light component of the lighting system are removed, the same applies to the retaining spring already described in the area of the lateral sections 24a, 13a and 24b, 14b for connecting the mounting rail and the device carrier to one another.
  • FIG 8 shows, in a sectional view perpendicular to the longitudinal extension, a lighting system designed according to the invention in an embodiment of a damp-proof luminaire.
  • the support rail is designed as an elongated housing 70 with a bottom section 72 and two adjoining, laterally spaced side sections 73a, b, which extend vertically downwards from the bottom section 72 approximately vertically in the installed position.
  • the housing 70 has, at the respective free end of the side section 73a, b, a groove 74a, b delimited by two groove side walls that extend in parallel and are here horizontally spaced apart.
  • the lighting system according to the invention also has a trough-shaped optical cover 90 which has microprismatic structures 91 on the inside for directing light.
  • the optical cover 90 On its free legs, the optical cover 90 comprises springs 92a, b in the form of side leg end sections which, in the installed position, correspond to the respective groove 74a, b of the housing 70.
  • the springs 92a, b of the optical cover 90 are in the assembled state in the respective groove 74a, b of the housing 70 received locked.
  • the respective outer groove side wall 75a, b has a latching element 76a, b on its inside, which corresponds to an associated latching element 93a, b of the optical cover 90.
  • the elongated equipment carrier 80 has laterally spaced apart side sections 83a, b, wherein in the illustration Figure 8 the arrangement of the flexible circuit board equipped with lighting means is not shown.
  • the equipment carrier 80 can have any configuration of an equipment carrier described above.
  • the device carrier 80 is not directly connected to the mounting rail 70 or the housing. Instead, the optical cover and the device carrier are connected to one another, in particular latched to one another, so that the device carrier 80 in this embodiment is connected to the housing 70 via the coupling of the optical cover to the latter.
