20100045186DUAL BRIGHTNESS TWINKLE IN A MINIATURE LIGHT BULB - A circuit for high-low flashing in a series-wired light string circuit. The series-wired light string includes miniature incandescent bulbs disposed in respective light sockets. A resistive element connected in series with a bi-metallic thermal switching element is mounted—as a shunt—either inside the light socket or inside the bulb, so as to be connected in parallel with the bulb filament. The bi-metallic thermal switching element, in series with the resistive element, electrically switches the resistive element off and on across the bulb filament. The bi-metallic thermal switching electrical contacts are in the normally closed position. Because the resistive element is in parallel with the bulb filament when the bi-metallic switching element is in its normally closed position, the bulb filament brightness is at its low state. As current flows through the resistive element and the bi-metallic thermal switching element, the bi-metallic switching element is warmed and activated and moves from its normally closed position to an open position. The shunt is now removed from across the bulb filament and the bulb illuminates brighter. Since the resistive element no longer passes current through it when it opens, it cools. When it cools sufficiently, the bi-metallic switching element moves back to its normally closed position. The cycle is repeated.02-25-2010
