  • the chimney-like design of the housing causes a reinforcement of the air flow or convection, which is also here is called chimney effect. This cooling effect is supported by the fact that heat loss is transmitted directly to the housing in the area of the adjacent creeks.
  • Another advantage of the invention is that the inventive design of the lighting device in different positions or positions is effective because a congestion of air is prevented by the chimney effect acts not only in the longitudinal direction of the housing but also in the front and rear of the housing.
  • the lighting means is designed as an LED module with at least one LED and fixed to the end wall.
  • One of the advantages of the invention is that a light source with a long life and advantageous light properties in a particularly compact design with the acting as a carrier module end wall of the heat spreader is directly connected.

  • the end wall has at least one radially inwardly directed channel which opens into at least one orifice in the end wall, the mouth preferably being arranged approximately centrally in the end wall.
  • One of the advantages of the invention is that the removal of heat loss by air thereby improves and the formation of heat build-up is prevented.
  • the reflector protrudes into the trough and / or the reflector projects at least partially into the housing.
  • the lighting device can be realized in a compact design, wherein the cooling of the lamp or the dissipation of heat loss is still efficient.
  • the chimney effect described is always guaranteed.
  • each cam has a width b which is related to an imaginary outer mean diameter D of the trough such that effective heat loss of the luminous means can be dissipated via the cams to the housing and to air flowing through the channels so that both effects are advantageously combined.

  • the heat spreader made of light metal, in particular aluminum, is formed.
  • the heat spreader with trough, cam and / or réelleverfeilettin can be produced by die-casting. A reworking of the die-cast heat spreader, in particular the end wall, cams, bores and / or heat-conducting elements is possible with known processing methods.
  • the heat spreader can also be subsequently surface treated for improved heat conduction.
