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.
