Luminous diffused light panel with low energy consumption and limited thickness

DETAILED DESCRIPTION This invention has the aim to obtain a luminous diffused light panel characterized by low energy consumption and limited thickness, requiring only a limited number of led's.
According to this invention, the luminous panel consists of a plate assembly and accessories implemented as follows.
The first plate consists of transparent material, for instance metacrylate, polycarbonate, glass, crystal or any other light conducting material, provided along one, two or more of its edges with a linear led assembly mounted on a suitable support and sequence energized.
This support may be a printed circuit and a reflecting element, further securing the perfect positioning of the led's, is inserted between the support and the polished edge of the plate.
The back side of this first transparent plate is prepared to reflect and diffuse the led emitted light by covering this surface with a white paint coat or with a glued or adhesive film of suitable thickness and material.
This first plate is usually flat but it may also be curved.
In this way, the light of the led's propagates through the light conducting plate and reflects on the paint or film, coating its back surface, thus diffusing the light outwards.
A second opaline plate, placed at a few millimeters from the first transparent plate, will further diffuse the light from its surface at an extraordinary high emission uniformity.
The latter plate may be replaced by two plates having a lower opacity grade but which will be positioned nearer to the first plate so as further to reduce the thichness of the luminous panel.
A third protective plate in transparent material will be placed in front of the second plate at a few millimeter distance or will be resting on the second plate, while another protective plate, which needs not be transparent, may be placed behind the first plate.
The luminous panel thus described will diffuse the light only from the second opaline plate surface.
The case is also considered in which a luminous panel diffuses the light from both sides
