Concept
Landscape lighting
Summary
Landscape lighting or garden lighting refers to the use of outdoor illumination of private gardens and public landscapes; for the enhancement and purposes of safety, nighttime aesthetics, accessibility, security, recreation and sports, and social and event uses.
Light pollution exacerbated by excessive, misdirected or obtrusive use of light, but even carefully used light fundamentally alters natural conditions. As a major side-effect of urbanization, it is blamed for compromising health, disrupting ecosystems and spoiling aesthetic environments.
The public landscape and gardens have been illuminated for as long as interior structures have – for beauty, security, circulation, and social occasions; since ancient times by firelight from wood, candles, and animal-plant oil fells in torches, sconces and lanterns. Since the 17th century's introductions of new interior illumination fuels, the technology has then been used outdoors and in gardens. As systems were developed for power delivery, Gas lighting of the 19th century and electric light of the 20th century became part of exterior functioning and design.
Conventionally generated and sourced electricity remains the most used source for landscape lighting in the early twenty-first century. With the combination of increasing demand for more efficient lighting, increasing availability of sustainable designs, global warming considerations, and aesthetic and safety concerns in garden and landscape design the methods and equipment of outdoor illumination have been evolving. The increasing use of LEDs, solar power, low voltage fixtures, energy efficient lamps, and energy-saving lighting design are examples of innovation in the field.
There are many different types of landscape lighting systems, controls and switching, wiring connections, fixture types, functions-purposes-styles, and light sources.
