Abstract: A non-hermetically sealed LED system containing an active composition having an amount between 0.06 and 2.5 mg per cm2 of the system optical window area is described. The active composition contains an active material in powder form, wherein at least 75 wt % of the active material is chosen from one or more of active carbons, silver, copper, zinc, copper oxide, zinc oxide, calcium oxide, and silver oxide.

Abstract: A composite transparent lighting device is described. The device has a transparent substrate, an uniform distribution of low concentration dielectric particles, reflective perimeter and perimetral discrete light sources, of improved appearance both in the inoperative state of the device, and at the same time capable of providing good quality lighting when the device is active, i.e. when the discrete light sources on the perimeter of the device are turned on.

Abstract: Compositions containing a mixture of non-evaporable getter alloys are described. The compositions, after having lost their functionality in consequence of the exposure to reactive gases at a first temperature, can then be reactivated through a thermal treatment at a second temperature that is lower than the first one.
