What factors should I consider when constructing a light box with ACRYLITE® EndLighten acrylic sheet?

ACRYLITE® EndLighten acrylic sheet uniformly distributes the light entering through its edges and redirects it over the entire surface with the highest possible optical output ratio. The brightness of a luminous display therefore depends largely on the power and number of light sources employed, as well as on the size of the edge surface (thickness of the chosen ACRYLITE® EndLighten acrylic sheet).

The distance between the light source and the edge of the ACRYLITE® EndLighten acylic sheet must be as small as possible so that plenty of light directly enters the sheet. An ideal distance is 0.040” – 0.118” (1mm - 3mm).

The light source can be provided with a reflector to ensure that a maximum amount of light enters the edges (see drawing).

Edges that are not lit should be covered with reflective material such as adhesive tape. The luminous displays can be installed with one or two radiant surfaces. If only one side is light-emitting, a highly reflective cover should be provided on the back. The lit edges should have smooth surfaces. Edge polishing improves light entry via the edge.

The motif carrier should be made of light-diffusing material so as to distribute the light exiting the ACRYLITE® EndLighten sheet uniformly towards the observer. Printable film is suitable as a motif carrier, but paper can also be used. Practically all types of glazing are suitable for protecting the motifs, particularly tough, impact-resistant ACRYLITE® AR acrylic sheet.

ACRYLITE® EndLighten sheet is available in the standard size of 120” x 80” (3,050mm x 2,030mm) and thickness of 0.236” (6mm), 0.315” (8mm), 0.394” (10mm), and 0.472” (12mm).
