Abstract (en)
[origin: GB2239746A] A plurality of series connected LED's are caused to flash simultaneously by means of an integrated circuit flasher built in to one of the LED's. There may be from 1 to 1000 LED's in addition to the one with the flasher circuit. The LED's may be energised from an A.C. power supply via a diode-capacitor voltage doubler D1, C1, D2, C2 and a zener diode Z1 regulator. <IMAGE>
Abstract (fr)
L'invention se rapporte à un circuit qui comprend une unité de lampe DEL (lampe à diodes électroluminescentes) clignotante, qui est capable de fonctionner à partir de diverses formes et divers types de signaux c.a. sinusoïdaux ou quasi sinusoïdaux et de sources de courant avec des tensions électriques allant jusqu'à 11 000 volts et des fréquences allant jusqu'à 100 000 Hertz appliquées à son entrée. La figure illustre le circuit de base.
