The use of Christmas lights goes back to 18th-century Germany where they decorated Christmas trees in wealthy homes. Christmas trees displayed publicly and illuminated with electric lights became popular at the beginning of the 20th century. In Britain, string of lights displayed on Christmas trees, walls and doors are called "fairy lights".



使用圣诞灯饰可以追溯到18世纪的德国，那时候有钱人的家里会装饰圣诞树。公开展示，以及用电灯来装饰圣诞树的习俗则是在20世纪初才开始流行的。在英国，圣诞树上，墙壁上和门上悬挂的长串灯饰被称为“童话灯”。
