Christmas lights

A light chain consists of several lined up against a common carrier bulbs, especially bulbs or light emitting diodes.

It was operated (eg 230 V) earlier with mains voltage; For safety reasons they are today with a network connection device and low voltage ( eg 24 V) in the trade. Applies to the European Union that lights that are suitable for outdoor use, have to satisfy a specific type of protection, such as IP 44, represented by this string or the symbol of a water droplet in the triangle.

Thus in from chains in series powered bulbs in case of failure of a lamp does not fail the entire lighting and the defective lamp is locatable, is located in each bulb as a varistor current bridge, which ensures the current flow even when broken filament.

Traditional lights, which are used for Christmas, often have bulbs in candle form and attached instead of candles on the branches of a Christmas tree.

Especially in light of the fact that is more and more attention to energy efficiency, more and more lights come on with LEDs. Due to their higher efficiency, these have a much lower power consumption (up to 80 % less compared to incandescent lamps ) and are less harmful to the environment. There is a wide range of colors, also are used by some providers already "warm white" LEDs offered.
