Definitions

  • the present invention relates to the technical field of lighting, and in particular to a combination between a light track provided with LED sources and at least one lateral accessory, preferably at least one sound-absorbing element, which can be fixed to said light track after the installation of said light track.
  • Lamps using LEDs as light sources have become very popular, due to LED's low cost and high efficiency.
  • light track are known, which can be fixed to a ceiling both directly and through a hanging system, which use LEDs as light source.
  • Noise pollution is caused mainly by an excessive exposition to high-intensity sounds and noises.
  • Italian law n. 447/1995 art. 2 provides the definition of noise pollution: "the insertion of noise in the living environment or outdoor environment such as to disturb resting and human activities, danger for human health, damage to ecosystems, material goods, monuments, living environment or of the outdoor environment or such as to interfere with the normal functioning of said environments".
  • the level of acoustic pressure (measured in decibel, dB), is the increase, over a logarithmic scale, of air pressure with respect to a state of stillness in the air. Very generally, a level of noise of 50-60 dB can be perceived as unpleasant.
  • US2007058377 of Zampini et al. discloses a light track having a construction similar to the one of the present invention.
  • the box shaped body comprises four sides: excluding the one from which light is emitted, at the other three sides there are provided mortises which are as long as the track in which tenons having different forms can be inserted (see figures 7-22 ) and which allows to secure the track to the ceiling or to the walls or to insert accessories in the mortises.
  • mortises which are as long as the track in which tenons having different forms can be inserted (see figures 7-22 ) and which allows to secure the track to the ceiling or to the walls or to insert accessories in the mortises.
