Definitions

  • the invention relates to an elongated lamp according to the preamble of claim 1.
  • a generic lamp to which the present invention relates, has at least one mounting body, a circuit board and a cover.
  • the mounting body and cover can jointly form a housing which encloses an interior space in which all the essential lighting components are contained.
  • a luminaire can also be of a more complex construction, for example the luminaire can also have a mounting rail which can be fastened to a component, for example a wall or ceiling, the mounting body being able to be attached to the mounting rail and, for example, also essential components within the mounting rail the lamp, for example cables for power supply and control gear, can be arranged.
  • the cover forms the light emission side of the lamp.
  • LED units arranged on the circuit board emit light which occurs on the inside of the cover and is emitted by the cover.
  • the cover of a generic luminaire has a light outlet section which is arranged vertically, ie along a vertical direction, above the circuit board and within its horizontal extent the board is arranged.
  • a plurality of LED units which are arranged next to one another in the longitudinal direction and spaced apart in the longitudinal direction and are designed to emit light upwards which strikes the cover and is emitted to the outside from the light exit section of the cover.
  • the cover also has wall areas which, starting from the light exit section, extend vertically towards the mounting body and which are supported on the mounting body.
  • the wall areas thus enable the cover to be mounted on the mounting body.
  • the wall areas are in direct contact with the assembly body, for example are pressed vertically against the assembly body, for example via known snap-in, clamp, screw or other suitable connections.
  • Embodiments are also known in which wall areas are in direct contact with an intermediate element, which in turn bears against the mounting body, for example on a circuit board, which is fixed on the mounting body.
  • the wall areas ensure that the cover is supported against the mounting body.
  • the LED units are arranged between the wall areas in a transverse direction that runs perpendicular to the longitudinal direction and perpendicular to the vertical direction.
  • the wall areas thus form a transverse section between them in which the LED units and the light exit section are arranged without a further wall area formed by the cover ensuring that the cover is supported on the mounting body within this transverse section, as a result of which the highest possible luminous efficiency can be guaranteed.
  • Preferred is over at least 50%, especially over at least 70% of the vertical extent of the wall areas, which is defined by the lower vertical end of the wall areas and the transition of the wall areas to the light exit section, no cover area covered by the cover is arranged in the transverse section formed between the two wall areas.
  • the wall regions preferably also extend in the longitudinal direction, in particular continuously over an elongate longitudinal section, in particular over at least 80% of the longitudinal extent of the cover, so that the cover can be supported as well as possible with respect to the mounting body.
