Abstract

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>

Description

A FLASHING LED LAMP ASSEMBLY This invention relates to a circuit for electric reactively driving in a practical manner and causing to flash on and off S bank of semi-conductor devices, commonly known as Light Emitting Diodes, (hereinafter referred to as LED's), by me of an alternating current and voltage, (hereinafter referred to a.c. or a.c. power Sources, or the mains), and operating with electrical pressures of upto 11,000 Volts and frequencies of upto 100,000 Hertz. The circuit and LED's together form a practical LED Flashing Lamp Assembly.
According to the present invention there is provided a circuit comprising 4 resistors, a metal oxide varistor, 2 capactiors, a zener diode, a flashing type LED with a built-in integrated circuit, (the built in integrated
circuit causes the LED to flash), #and an unspecified but finite number of light emitting diodes connected in series with the flashing LED. The whole lamp assembly and circuit is configured and arranged in accordance with figure 1.
According to the present invention the salient points of the circuit described are as follows:- 1. Identification of the fact that it is the flashing LED which causes the other non-flashing LED's, which are connected in series with the flashing LED, to flash.
2. The incorporation of resistor R1 connected across the flashing and nonflashing LED assembly.
