Patented Sign Hero Technology

US Patent #10,883,669



Sign Hero is Keystone’s inventive solution for sign illumination featuring a unique, patented light emitting diode (LED) light tube technology (U.S. Patent No. 10,883,669). Among the product’s innovations are rotatable end cap assemblies featuring a locking mount with a rotation cam, allowing the tube to be adjusted regardless of socket orientation in the sign. Coupled with Keystone’s DirectDrive technology, which eliminates the need for an external driver or ballast while retaining existing sockets, this technology makes LED tubes more versatile and the easiest lighting solution to install. It’s the ideal solution for retrofits or new sign installations, and delivers on Keystone’s promise of Light Made Easy®.
