Definitions

  • This invention relates to a circuit for electric reactively driving in a practical manner and causing to flash on and oft a bank of semi-conductor devices, commonly known as Light Emitting Diodes, (hereinafter referred to as LED's), by means of an alternating current and voltage, (hereinafter referred to as a . c . or a.c. power sources, or the mains), and operating with electrical voltages of upto 11,000 Volts and frequencies of upto 100,000 Hertz.
  • the circuit and LED's together form a practical LEE) Flashing Lamp Assembly, for indication purposes.
  • a ci rcu.it comprising 4 resistors, a metal oxide varistor, 2 capacitors, a zener diode, a flashing type LED with a built-in integrated circuit, (which causes the LED to flash), 2 power diodes, 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.
  • 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.
