<p>The invention concerns the field of lamphouses. More particularly, it concerns a diffusing coating designed to be deposited on a substrate to homogenise a light source. The inventive coating consists of particles agglomerated in a binder and is characterised in that the particles have a mean diameter ranging between 0.3 and 2 microns, the binder being in a proportion ranging between 10 and 40 % by volume, the particles forming aggregates whereof the dimension ranges between 0.5 to 20 microns, and preferably less than 5 microns and the coating having a contrast attenuation higher than 40 %. The invention also concerns uses for producing lamphouses and more particularly planar light plates.</p> |
