Uniform surface lighting thanks to LEDs

Large-scale, slim backlighting is used in a multitude of sectors and the demand for high-luminosity solutions is growing continuously. LEDs (Light Emitting Diodes) are an economical solution and thanks to their durability the ideal illuminant for such applications. Typical examples are large-scale luminous displays for furniture, store fixtures and fair booths, picture frames, citylight posters as well as luminous walls and partitions.

Engraving of surface

The panels used are made of a light-conducting material such as acrylic, which generates a uniform light source. Even illumination over the whole material surface is vital in this application, whereby the light must be deflected vertically to the surface. A raster is created on the surface during laser engraving so that the light that is fed in via the cut edges is emitted evenly. The arrangement of the raster dots or lines can be optimised via the software. The number and distribution of the raster dots enables targeted control of the luminosity.
