An electronic holiday light controller usually has a diode bridge followed by a resistor-based voltage divider, a filter capacitor and a fixed-program microcontroller. The micro-controller has three or four outputs which are connected to transistors or thyristor which control interleaved circuits, each with lamps of a single color.
A chase is an electrical application where strings of adjacent light bulbs cycle on and off frequently to give the illusion of lights moving along the string. With computerized lighting consoles, building chase sequences has become easier, while previously chases used mechanical means, such as a wheel with an electrified spindle which strikes electrical contacts for each circuit.
On DC, polarity can be switched back and forth so as to change the color of the lights, such as in Christmas lights that can be either white or colored. Battery-powered lights, which are wired in parallel, can also create a simulated "chasing" effect by alternating the polarity for each LED attached to the string, and controlling the positive ...
A popular Christmas tree light controller, which was sold at a number of national retailers, is being recalled due to a possible fire hazard. More than 44,000 controllers from Mr. Christmas were ...
1. Always Inspect Lights Before Hanging Them. The first thing you should do before hanging the Christmas lights is to inspect the plugs, wires, and sockets for any problems.
A New York teenager is spreading holiday cheer in an inspiring and sustainable way this Christmas. For the fourth year running, Andrew Reid, 19, has constructed a giant dazzling holiday light ...
Electroluminescent wire (often abbreviated as EL wire) is a thin copper wire coated in a phosphor that produces light through electroluminescence when an alternating current is applied to it. It can be used in a wide variety of applications—vehicle and structure decoration, safety and emergency lighting, toys, clothing etc.—much as rope ...
