ABSTRACT:
There is disclosed herein a new form of sign or graphic display which simulates a neon sign. The same comprises a hollow tube or tubes which are formed into desired shapes, such as letters, graphics and the like. These tubes are lit along the side edge by directing illumination to the side thereof, preferably through colored material, paint or dye to provide a colored display. Several arrangements for illuminating the sides of the tubes are disclosed. In the case of flexible vinyl tubing, a method is disclosed for forming the same into the desired shapes by inserting a solid Teflon rod in the tube prior to bending, bending the tube to the desired form, and applying suitable heat in order that the tube will assume the desired shape, then cooling the tubing and removing the solid rod.
