Christmas lights consume a lot of electricity. If you have a string of 50 5-watt bulbs, the power consumption of this string is 250 watts! Most people decorate trees with two to three strings of lights and houses with 10 strings of light bulbs, so you can imagine how much power is required!
The whole light string will not flash. Obviously, these bulbs have no shunt (if any, the remaining bulbs will not blink), so when the flash bulb goes out, the rest of the bulbs will go out accordingly, unless you replace the flashing bulb.
More complex light bulbs have 16 function controllers, you can control the light bulbs in various interesting patterns. In these systems, you will usually find a control box that drives four independent mini light strings. The four light strings are staggered, not one after another. If you disassemble the control box, you will find its structure is very simple. It contains an integrated circuit, four transistors or a triac-one switch drives a string of lights. The integrated circuit only needs to open the triac to light one of the light strings. By properly ordering the triacs, various lighting effects can be designed!
For many Americans, a permanent symbol of Christmas is the National Christmas Tree on the Washington National Lawn. During an evening celebration, the President or First Lady usually lights the Christmas lights on this tree. For many Christians, Christmas candles may be the best gift.
