To illuminate the facades of buildings use special spotlights that are mounted on special brackets on the roof, walls, buildings and land.
In Russia and abroad produced many types of floodlights to illuminate the facades of buildings ranging from 35 to 2000 Watts. In the latest generation of projectors are commonly used halogen lamps and LEDs.
If you compare LED and halogen floodlights to illuminate building facades on the main characteristics, in many LEDs are absolute leaders. By quantity of light emitted by LEDs in the lead direction of the light radiation - halogen lamps lose up to 60% luminous flux. LEDs win for color purity and wide range of colors - up to 16 million colors (light filters halogen bulbs burn out quickly), ease of operation and energy savings (up to 6 times compared with halogen lamps). In addition, LEDs improve reliability and service life of lamps, as well as reduce maintenance costs (lifetime in continuous operation - 100 thousand hours).
With the help of a certain number of elements and various optical lenses LEDs allow you to create different projectors and lighting with the power required to illuminate the building. Modern control systems use light-emitting diode searchlights dynamic effects that are not available halogen lamps. The only drawback of LEDs - the high price and low unit capacity, ie for obtaining high luminous flux is required to use a large number of LEDs.
Over the past year or two, were first successful installation of LEDs in architectural lighting cities in Europe and the U.S. made the first attempts to use them in Moscow. In the city the use of LED lighting effectively, experts say that for private homes in the next few years this type of lighting would be dominant.
