LUMINESCENT PLANAR SHEET

摘要

A luminescent planar sheet is constructed to provide illuminated alphanumeric characters particularly suitable for mounting upon the planar surfaces of a vehicle. Preferably the luminescent planar sheet can produce visible light, infrared light, or both. A switching system is connected to the luminescent planar panels for selectively controlling power to produce visible light and/or infrared light. The luminescent planar sheet includes a protective coating which permits the passage of both visible light and infrared light, but substantially blocks most or all ultraviolet light.

1. A planar light panel comprising:
a planar light panel having a bottom surface and a top surface for producing light; and a protective coating covering said planar light panel's top surface, said protective coating blocking at least 60% of ultraviolet light below 350 nanometers (nm), but allowing at least 80% of visible and infrared light above 450 nanometers.
