Abstract
A circuit board arrangement assembled by at least a first and a second circuit boards, each circuit board comprising: a portion of a circuit; and a first and a second electrical terminals to be electrically connected to a respective first and a second electrical terminals of the other circuit board of the first and the second circuit boards, so as to couple the portions of the circuit of the first and the second circuit boards, wherein the first and second electrical terminals on the circuit board are coupled with each other via the portion of the circuit on the other circuit board of the first and the second circuit boards, at least one board further comprising: a voltage suppression element (TSS, TSS) in the board connected across the first and second electrical terminals of the board, said voltage suppression element (TSS, TSS) is adapted to become conductive when a voltage thereacross reaches a threshold; characterized in that the portion of the circuit comprising at least one LED, and said LED (LED) of the first circuit board (B) and said LED (LED) of the second circuit board (B) are forwarded in the same direction and to be series connected between a first interconnection (LED+) of the first electrical terminals of the first and the second circuit boards and a second interconnection (LED−) of the second electrical terminal of the first and the second circuit boards. The voltage suppression element is able to prevent overvoltage/arcing due to a disconnection of the series connection of the LEDs of the first and second circuit boards, as well as a disconnection of a interconnection of first terminals, and a interconnection of the second terminals.
