Definitions

  • the present invention relates to a LED lighting device, particularly but without limitation to a low voltage supply LED lighting device as defined in the preamble of claim 1.
  • LED lighting devices are known in the art, which comprise a concave reflector designed to reflect the light emitted by the LED along one axis of the reflector.
  • LED lighting devices are also known, which are mounted to a support secured via more or less articulated systems to additional supports, to be coupled to an electrified track. Such articulated systems allow the light beam generated by the LED lighting device to be oriented as needed by the user.
  • This constraint is an apparent limit whenever the LED lighting device should be oriented to define an appropriate light beam direction.
  • the present invention provides a LED lighting device that can rotate relative to the articulated coupling system even through an angle greater than a round angle.
  • numeral 1 generally designates a LED lighting device having a support 2 secured by a more or less articulated securing device 3 to a wall, such as the ceiling or a vertical wall of a room, or a walkway surface; in the example of Figure 1 , the securing device is adapted to be mechanically and electrically coupled, via the securing device 3, to an electrified track (not shown).
  • This boss 20 is designed to engage with one of the two seats 16A and 16B only.
  • one seat 16A is designed to be appropriately shaped at a portion 16C thereof, preferably its end portion, for unique coupling of the boss 20 and the portion 16C.
  • the second power supply means 17B comprise:
  • the container 34 preferably has a cylindrical symmetry.
  • the invention provides a LED lighting device that can adequately dissipate the heat generated by the LED, even when a high-power LED is used.
