The evolution of lighting technology has led in recent years to the need to create design objects that were unthinkable until recently. The backlight marking technique allows you to create plexiglass panels illuminated from the side, by means of LED light. It is therefore possible to spread the light on an entire plexiglass panel without necessarily having to install LED lights in the back. In fact, the backlight marking creates an effect in the panel that guarantees the diffusion of light with a led stripe placed on one or more sides, without the effect of dark points and light points. The plexiglass panels with backlight marking allow to effectively illuminate large rooms or printed images by exploiting the maximum diffusion of light, which can start also from only one side of the panel, optimizing costs. The backlight marking of plexiglass is ideal for those who want to offer their customers alternative and design lighting systems, and for those involved in visual communication (signs, displays, shelves for showcases and cabinets, counters and furnishing accessories for shops, signs, etc …).
