发明名称 Electroluminescent lamp-based greeting cards
摘要 An illuminated card device formed from sheet stock, for use as a greeting card or the like. One or more EL lamps are attached either flat against the card or mounted as pop-up elements. Two wires lead out from the EL lamps to a high voltage driver circuitry that converts a low voltage signal into an AC high voltage signal (approximately 40V to 300V peak to peak.) This circuitry is mounted on a PCB, hidden from view. A sliding tab in the shape of a 't' slides through two slits in the card. Metal elements are mounted to the tab and between the two slits. When the card is opened, the two metal elements make contact, creating an electrical short to allow the battery to supply current to the high voltage conversion circuit. The high voltage driver circuit provides signals to illuminate the EL lamps.
