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 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.
According to the present, invention there is provided 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. 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.
