We all know people like to decorate there houses, stores, trees, streets... in celebrating days or holidays, especially in Christmas and New Year. And actually there are several different christmas lights and each are being used in different places and holidays. But we are sharing with youy gus today about what wikipedia showing us christmas light is!
Main Meaning: Christmas lights (also known informally as fairy lights) are lights used for decoration in preparation for Christmas and for display throughout Christmastide. The custom goes back to the use of candles to decorate the Christmas tree in Christian homes in early modern Germany. Christmas trees displayed publicly and illuminated with electric lights became popular in the early 20th century. By the mid-20th century, it became customary to display strings of electric lights as along streets and on buildings Christmas decorations detached from the Christmas tree itself. In the United States, it became popular to outline private homes with such Christmas lights in tract housing beginning in the 1960s. By the late 20th century, the custom had also been adopted in non-western countries / regions, notably in Japan and Hong Kong.
In many countries, such as Sweden, people start to set up their Christmas lights, as well as other Christmas decorations, on the first day of Advent. In the Western Christian world, the two traditional days when Christmas lights are removed are Twelfth Night and Candlemas, the latter of which ends the Christmas-Epiphany season in some denominations. Leaving the decorations up beyond Candlemas is historically considered to be inauspicious.
Technology: The technology used in Christmas lighting displays is highly diverse, ranging from simple light strands, Christmas lights (a.k.a. Fairy lights), through to full blown animated tableaux, involving complex illuminated animatronics and statues.
Christmas lights (also called twinkle lights, holiday lights, mini lights or fairy lights), that are strands of electric lights used to decorate homes, public/commercial buildings and Christmas trees during the Christmas season are amongst the most recognized form of Christmas lighting. Christmas lights come in a dazzling array of configurations and colors. The small "midget" bulbs commonly known as fairy lights are also called Italian lights in some parts of the U.S., such as Chicago.
The types of lamps used in Christmas lighting also vary considerably, reflecting the diversity of modern lighting technology in general. Common lamp types are incandescent light bulbs and now light-emitting diodes (LEDs), which are being increasingly encouraged as being more energy efficient. Less common are neon lamp sets. Fluorescent lamp sets were produced for a limited time by Sylvania in the mid-1940s.
Christmas lights using incandescent bulbs are somewhat notorious for being difficult to troubleshoot and repair. In the 1950s and 1960s, the series circuit connected light sets would go completely dark when a single bulb failed. So in the fairly recent past, the mini-lights have come with shunts to allow a set to continue to operate with a burned out bulb.
However, if there are multiple bulb failures or a shunt is bad, the string can still fail. There are two basic ways to troubleshoot this: a one by one replacement with a known good bulb, or by using a test light to find out where the voltage gets interrupted. One example made specifically for Christmas lights is the LightKeeper Pro. For additional information, see the troubleshooting section of the Holiday lighting technology article.
When Christmas light manufacturers first started using LEDs the colors seemed very dull and uninspiring. Even the white lights, which were typically single-chip LEDs, glowed with a faintly yellowish color that made them look cheap and unattractive.
