Claim Text:
1. A low power bypass circuit for use with a string of series-connected LEDs, the low power bypass circuit comprising: a zener diode connected in series with a resistor which zener diode and resistor combination becomes conductive upon the failure of an LED or the connection of the string of series-connected LEDs to a reverse polarity flow of electrical energy; said zener diode and resistor combination causing a triac to become conductive upon the failure of an LED so the flow of that electrical energy no longer flows through said zener diode and resistor combination is reduced by the flow of electrical energy through said triac; said zener diode and resistor combination causing a triac to become conductive upon the connection of the string of series-connected LEDs to a reverse polarity flow of electrical energy so that electrical energy flows through said zener diode long enough to cause said triac to become conductive, thereby reducing the flow of electrical energy through said zener diode.
