6) Landscape lighting used in peacetime, the general holidays, major holidays and other control mode.
2.4 Application of intelligent lighting control system features
2.4.1 use of lighting control system, realization of the intelligent lighting control, lighting systems can run in automatic state.
1) The system will be pre-set to switch a number of basic working conditions, such as: "day", "night", "security" and "clean", "Weekend" and "lunch" and, according to pre-set time automatically in the to switch between various working conditions. For example, work time comes, the system will automatically turn on the lights and the light intensity is automatically adjusted to the most appropriate level of staff. In the window Room, the system can intelligently use of outdoor natural light, when the weather was fine, automatically dimming interior lamp; weather and dark, indoor lamp auto light, to always maintain a constant brightness of room (at pre-set requirements of the brightness).
2) When the end of each working day, the system will automatically enter the "evening" work status, auto slow dimming the lights of the region; the same time, the system function will automatically detect the presence of force, so that no one in the office of the lights automatically turn off ; same time, there can guarantee detection of the office employees to work overtime at the appropriate brightness light.
3) The system of public corridors and staircases and other public areas of the light coordination, when the office has employees to work overtime, the staircases, corridors and other public areas to maintain the basic brightness of the lights, only when the person has completed all the post-office before the light transferred to the "safe" state or turned off.
4) manual control panel or remote control, free to change the illumination of the region.
5) For the reception hall, restaurant, conference rooms, lounges and entertainment venues, may be based on different times of day, different uses of the pre-set lighting scenes, use only the best call to pre-set lighting scenes, to desired visual effects.
2.4.2 maintain the consistency of illumination of new buildings into use, the illumination than the required high illumination. This is taken into account as time goes on, the efficiency of light reflection rate and room walls the sake of continued decay. If the designers in the early design of the standard illumination, then, not how long it will less than the standard room illumination, illumination not meet business requirements. It is because of the high illumination of this new design of the room, not only resulted in use of office space (or twice at intervals decoration) of the illumination inconsistency, and because of the high illumination unnecessary waste of energy. Use of lighting control systems, as can be intelligent dimming, though still high illumination design, but the system will be in accordance with the standard pre-set brightness to the office during the period in the use of constant illumination, without reducing the efficiency of lighting and wall reflection coefficient of attenuation.
2.4.3 create a good working environment, improve work efficiency in the office, with dimmable electronic ballasts for fluorescent lamps in the smart Under the control of lighting control system with the traditional fluorescent lighting systems have significant advantages compared to. Conventional fluorescent ballasts to 100Hz frequency flashing (2 times the grid frequency), this strobe enable staff to head swollen, eye fatigue and reduce work efficiency. The dimmable electronic ballasts are working in very high frequency (40kHz ~ 70kHz), not only to overcome the flicker, but also to eliminate the starter when the brightness of the instability, provides a comfortable environment conducive to health, but also improve the efficiency.
2.4.4 create a good environment for good lighting design service is able to create a warm, comfortable environment, adding to its artistic charm. For example, the customer's first impression of the hotel entrance to the lobby of the hotel reception area, elegant and unique light environment may give care Customers feel at home, add the goodwill of customers of the hotel, friendly and warm to attract a large number of customers; the banquet hall, function rooms such as the use light colors, and different shading intensity projection method can create three-dimensional, layered different color atmosphere, not only the guests have a comfortable living environment, but also to bring art to the guests to enjoy, so that people have the feeling linger.
2.4.5 Open Lighting control system can be integrated into the construction equipment through the network monitoring system (BAS), Building Management System (BMS), the realization of the unified management of the building.
2.5 Technical Analysis
2.5.1 Line Investment savings
Intelligent lighting control system is a system through the control bus to the various input, output and system support unit connected, power cable directly received from the distribution cabinet lighting or other electrical load, and without going through the switch. Do not have to consider when installing any control relationship, and then installed in the system settings through the software code of each unit's address in order to establish relations between the corresponding control. Compared with the traditional control method saves a lot of the original receipt of the switch to cable, but also shorten the time
