Abstract
A vehicle lighting system is provided primarily for use with emergency response vehicles. The vehicle lighting system includes at least one luminescent planar sheet affixed to a vehicle's mounting surface. The luminescent planar sheet includes a non-luminescent printed circuit board in the shape of a letter or number which has a top surface of a color which contrasts with the mounting surface's color. The luminescent planar sheet includes a plurality of light emitting LEDs which are surface mounted upon the printed circuit board so as to be arranged in the shape of the desired letter or number with the LEDs covering no more than 20% of the printed circuit board's top surface. Preferably, the LEDs cover no more than 7% the printed circuit board's top surface.
Claims12
A luminescent indicia assembly comprising:
- a luminescent planar sheet constructed to provide a non-luminescent indicia and a luminescent indicia, said luminescent planar sheet including a non-luminescent printed circuit board, said printed circuit board having a shape providing said non-luminescent indicia and having one or more layers of non-electrically conducting substrates and a plurality of electrically conducting pathways;
- said luminescent planar sheet including a plurality of light sources surface mounted upon said printed circuit board which are electrically connected to said electrically conducting pathways, said light sources are mounted substantially uniformly upon said printed circuit board to provide said luminescent indicia which is substantially the same shape as said non-luminescent indicia, said light sources covering no more than 20% of the surface area of said printed circuit board's top surface so that at least 80% of said printed circuit board top surface can be seen.
