<p>An illuminated sign (10) that produces a luminescent display that is especially suitable for attachment to an article of clothing such as a jacket (60) or cap (70). The sign (10) consists of an electroluminescent lamp (12) that produces a luminescent cool light, in either, white, yellow or green/blue, that is visible through the openings of an indicia stencil (26) affixed to the front of the lamp (12). The lamp is encapsulated in a film (24) that is further protected by a sign protecting cover (28) having an opening (30) into which is inserted the stencil (26). The signs power circuit consists of an inverter (46) that is powered by a battery (44). The inverter produces an output of 140-volts a-c at 400 Hz that is applied directly to the input of the electroluminescent lamp (12) and that is controlled by a power switch (48). The problems inherent with using protruding LEDs and the limitation of the displays that can be made with the LEDs is eliminated by using the stencil (26) in combination with the electroluminescent panel (12).</p> |
