LEDs produce light by the process of Electroluminescence. This is the phenomenon where by light is emitted from a material when an electrical current is passed through it. An LED chip is made from a material doped with 'impurities' to create a p-n junction between two types of semiconductors and electron holes. Electrons can only flow one way across the junction and as they do they fill electron holes causing their energy level drops and the release of photons (light).
Copper garden lights are a good way to complement a lighting layout that includes unique or artistic features such as statuary, fountains, wishing wells, and so forth. To keep the copper finish shiny and like new, you can protect it from the elements with a coat of clear lacquer. If however you want the copper to achieve a weathered, natural appearance, just leave it as is and let the forces of nature take its course. After some time exposed to the elements, the finish will eventually change into a blue-green "verdigris" sheen that has an elegant and vintage appeal.
This makes it a perfect alternative to a 120-volt system that must be installed by an electrician or lighting technician. Solar lights do not require the use of external cables and transformers because they are powered by the energy of the sun. The sun's rays are collected by small solar cell panels attached to the lights, which is converted into electricity and stored in batteries to power the fixtures at night. It is a self-generating power supply, which enable the lights to be used in many areas where it would have otherwise been too expensive or impractical.
