【正文】 e United Kingdom in this way to solve the underground construction and lighting, windowless building. Selection of highquality lighting Underground construction in the traditional, monly used incandescent and fluorescent lighting as a light source, highintensity gas discharge lamp is also used. unremitting efforts, incandescent light efficiency and life expectancy has been significantly improved, and prices fell Of particular note is the use of ceramic materials for the inner tube of the ceramic metal halide lamp, lightefficient, light colors better, more stable, and small size, high brightness, easy to do light projector. Recently, there was more advanced than the traditional source of new light source, which is the most typical of semiconductor lightemitting diodes. It has a highbrightness, low power consumption, fast response, long life light source can not be more than the traditional and the characteristics of the 21st century is recognized as the most promising source. Innovation is the neverending, we should not only familiar with the early development has been widely used in traditional light sources, but also should pay close attention to the improvement of traditional light sources, development and continuous emergence of new sources. In the design and construction, according to the nature of underground construction, size, characteristics and requirements, a prehensive parison of different sources of technical and economic indicators, selection of energy efficient lighting, using highquality green lighting, lighting distribution system optimized to maximize the effectiveness of lighting to play, allowing users more satisfied. To carry out various types of lamp dimming level for ease of scene change control Traditional lighting are necessary to open, do not need toclose, mode and control methods for rigid, it is very difficult to change the illumination and the scene, the user, even if not satisfied, just can not do it, if modified, would result in duplication of investment. With the advent of the information age, intelligent lighting system came into being, its plete control features and a variety of preset scenes can be switched to meet the needs of different users. Switches and dimmers are two control methods of intelligent lighting control system . control system through the rational management of time according to different people39。s programming interface, you can modify the parameters of the lighting condition. Field Control Often work in some places (such as conference rooms, control room, the main channel, it is important to office space) to install the smart switch instead of ordinary mechanical switches, the central monitoring puter does not work, we could also control the lighting at the scene. It consists of 230V AC power supply directly, rather than pressing the button switch can be used as an ordinary use of the switch。 lights, the lights gradually dimmed by the light. Softstart, soft turnoff can also protect the light bulbs, long life, save maintenance funds. In addition, the brightness of lights can be equipped with memory function, so as not to be repetitive settings. Fire control emergency lighting Demanding underground fire, the fire should be automatically activated emergency lighting the corresponding region, forced the closure of the general lighting circuit. Lighting fire incidents Center may choose to only ban the use of putercontrolled monitoring puter or site control, can also choose to have control over it. In addition, the control system to have good scalability, openness and electromagic patibility. Intelligent lighting control system is the underground construction of the subsystems of intelligent system can be through a standard interface patible with other control systems to the Inter. In order to suppress electromagic interference, letting the system has good electromagic patibility, bus transmission distance can be taken the following measures: with the possible electromagic interference near the electrical equipment (such as motors, power transformers, photocopiers, etc.) necessary to maintain segregation。 rise time, or voltage from the rated voltage of 5% to 95% of the time used to be more than 200μs. Intelligent lighting control system effectiveness and prospects Intelligent lighting control system using the benefits of the main problems: intelligent lighting control。 scenes transform flexible。 extended life light sou
