Edge Type
Backlights are positioned behind objects...
Backlights are positioned behind objects to create a silhouette. This technique is excellent for creating contrast on edges, detection of holes or voids in an object or to separate transparent from opaque.
Array type backlights use LED’s directly behind the diffuser. This produces very high intensity – (depending on the diffuser). Typical uniformity is +/- 10%. The construction of array type backlights makes them thicker than edge type backlights. They are typically 15-30mm thick but they have very thin/no frame around them in comparison so that they can often be butted together to cover large areas.
