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.
This fir comes pre-lit with more than 250 warm-white lights adorning its more than 756 branch tips to give it a full, lush appearance. Use the included controller to alternate between eight ...
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 ...
Christmas lights vary in energy usage. For many people, LED lights are the most energy and cost-efficient way to light a home, since shese bulbs produce little heat, translating into energy saving ...
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 lighting control console (also called a lightboard, lighting board, or lighting desk) is an electronic device used in theatrical lighting design to control multiple stage lights at once. They are used throughout the entertainment industry and are normally placed at the front of house (FOH) position or in a control booth .
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 ...
