Voltage-limiting and reverse polarity series type LED device
Abstract:
The present invention provides LEDs and zener diodes that are homopolar and connected in parallel to constitute the first set of LED and zener diode and a second set of LED and zener diode; the first LED and zener diode set and the second LED and zener diode assume a reverse polarity series connection to constitute the tandem LED device with voltage limited and reverse polarity; through the selection of connecting pins, it is used on direct current power source or alternating current power source which is its characteristics.
