ABSTRACT:
An interlocking lens structure comprising two opposed lens pieces is disclosed. Each of the lens pieces has a top portion including an edge having a first region formed with a groove and a second region formed with a projection. The first region of each of the lens pieces is adapted to mate with the second region of the other of the lens pieces. Each of the lens pieces further includes a side portion connected to the top portion and having two edges. One of the side portion edges is formed with a groove, while the other of the side portion edges is formed with a projection. The groove of each of the side portion edges is adapted to mate with the projection of the other of the side portion edges. The depth and the length of each of the groove/projection combinations can be varied to determine the amount of color separation between the lens pieces. The grooves and the projections also prevent light from escaping from the interior of the lens structure at the junction of the lens pieces.
