light diffusing acrylic
Endlighten is an acrylic sheet infused with colorless light diffusing particles. While regular acrylic only diffuses light around the edges, endlighten illuminates evenly across the entire surface. The images above show 1 sq foot of the material with a strip of RGB LEDs wrapped around it.
This material is available in a few different thicknesses and grades. The most relevant distinction between them has to do with the size of the final application. For example, for applications up to 24″ the L size will suffice, but applications over 51″ will require the XXL. The manufacturer also offers the material in two grades: regular and T. The T is specially formulated for LEDs and optimized for vertical viewing with a surface 250% brighter when viewed from the front.
Besides its light diffusing properties, endlighten has the same aspect and properties as regular clear acrylic: it can be laser cut, etched, etc.
Known applications for endlighten include interior decoration and multi-touch surfaces.
