In applied lighting engineering it is appropriate to associate the luminous temperature of different types of candlelight sources with natural sources of light.
To provide comprehensible classification of white lamps chrominance it is customary to divide all the sources into three groups: warm white, neutral white and cold white, or daylight.
Light emitting diodes are the best variant for the evening and nightly illumination of the buildings, constructions and other territories with different functions that will organically blend with any landscape and emphasize the most unordinary ideas of the architect. LED can be applied both for the background illumination and for the bright accentual lighting of the buildings, squares, streets and tunnels, architectural compositions, fountains and other objects. Tremendous durability, longevity and high economy of LED make it possible to use it successfully for the illumination of the cities and private landownership. One more indubitable advantage of LED illuminators is its capability of being used with a wide variety of transformers and drivers with direct or alternating voltage.
