Abstract
A transparent lighting system for a conveyance includes a transparent light active sheet material and an adhesive disposed on the transparent light active sheet material. The transparent light active sheet material includes top and bottom electrically conductive transparent substrates, a pattern of light emitting diode (LED) chips sandwiched between the electrically conductive transparent substrates, and a non-conductive transparent adhesive material disposed between the top and bottom electrically conductive transparent substrates and the LED chips. The LED chips are preformed before being patterned in the light active sheet material as an unpackaged discrete semiconductor device having an anode p-junction side and a cathode n-junction side. For the LED chips, either the anode or the cathode side is in electrical communication with one of the electrically conductive transparent substrates, and the other of the anode and the cathode side is in electrical communication with the other of the electrically conductive transparent substrates.
