The article is devoted the basic ways of forming a light image of city and aspects of the relationship architectural and luminous image of objects of architecture. The general trends of modeling light image of public buildings with modern means of artificial lighting. Analyzed and described to possibility of light-emitting-diode technologies, and also major their applications in practice of light design domains are examined. The article considers the prospects of LED modules. tapes, spotlights and lamps in the manufacture of tubular elements of outdoor advertising. The first Light Emitting Diode came to life 50 years ago as a semiconductor light source. LEDs then were used as indicator lamps in a number of electronic devices and principally as warning devices. With continuous development LEDs are now increasingly being used in all types of general lighting where the technology is proven in terms of energy saving. This trend is likely to continue as purchasers become aware of the substantial benefits LEDs have when compared to conventional lighting solutions. Initially the LED lighting industry targeted the commercial and military aerospace industries where the benefits of applying LED lighting technology have already achieved substantial acceptance. The energy savings produced are compounded by massive reductions in maintenance costs and the application of LED lighting is now commonplace in both retrofit and new build aircraft as the commercial benefits of this technology are proven beyond doubt. In general, current lighting in the public domain is dominated by traditional incandescent filament bulbs or fluorescent tubes and these processes have barely changed in more than 100 years. Those technology types and systems are fully understood and most people are comfortable with the range of fittings and versions available along with the associated cost implications. Common applications are virtually endless. However, the cost and efficiency of conventional lighting is now being questioned more broadly as people become more aware of the alternative means of lighting that are available. This awareness is expanding rapidly as changes in education, environment and law mean that new alternatives in lighting technology are more necessary than ever. Since 2008, LED lighting has been developing as a more generally accepted form of lighting with a number of big brand name traditional lighting manufacturers opening separate divisions focused on this new technology. Its application can make a major contribution to reduced running costs of both exterior and interior lighting whether it is in a private home, a public building or a commercial premises. Shock Resistance: Unlike conventional light sources, LEDs are not subject to sudden failure or burnout as there are no filaments to burn out or break. The light in LEDs emits from encapsulated silicon diodes immersed in phosphor which can be energised from a very low voltage input The application of LEDs to create light offers many opportunities to make, not only substantial savings in cost of general lighting, but also a significant reduction in environmental impact over conventional mains power generation. Light Quality: The quality of the LED white light can be tailored to suit the human eye, eliminating the eye strain that can have adverse and costly implications in certain working and living environments together with Health and Safety issues. LEDs do not produce ultraviolet light (however there are UV variants) and can be perfectly matched to a specific colour rendering index.
