Abstract:
1. A reverse polarity series type LED is formed by two sets of LED and diode assemblies in reverse polarity series connection wherein a first set consists of at least one or multiple homopolar series or parallel connected or series and parallel connected LEDs, and a second set consists of at least one or more homopolar parallel or series connected or series and parallel connected LEDs for further connection to the drive circuit formed by current-limiting impedance and/or power storage and discharging devices and/or voltage-limit circuit devices in order to produce required operational characteristics, its main formation consisting of: a LED ( a LED ( diodes ( by means of parallel connection between the LED ( by means of a reverse polarity series connection between the first LED and diode assembly with the second LED and diode assembly, a reverse polarity series type LED device is formed; wherein an independent connection terminal of the first LED and diode assembly is designated as the (a) terminal, the reverse polarity series connection terminal between the first and the second LED and diode assemblies is designated as the (b) terminal, and the independent connection terminal of the second LED and diode assembly is designated as the (c) terminal; a current-limiting impedance element ( the series positions of the impedance elements include: 1) the impedance element is connected in series with individual LEDs after which the impedance element is connected in parallel with diodes; and/or 2) the impedance element is connected in series between the power source and the reverse polarity series type LED; and/or 3) the LED connects to the diode in parallel and then connects to the impedance element in series.
