1 the use of intelligent lighting control system for the superiority of
1.1 good energy saving effect
Intelligent lighting control system using the main purpose is to save energy, smart lighting control system with a variety of "pre-set" control mode and control components, at different times on different degrees of illumination for accurate set-up and rational management of energy-saving. This automatic adjustment of the illumination means, take full advantage of the natural outdoor light, only when necessary when the la
mp or light to the required brightness, use the least energy to ensure that the required illumination level, energy-saving effect is very clear, usually ranging from more than 30%. In addition, the intelligent lighting control system for fluorescent lamp dimming control, etc., due to the use of a fluorescent active tunable filter electronic ballast technology and reduce the harmonic content, to improve the power factor and reduce the low-voltage reactive power loss.
1.2 to extend the life span of light source
Light source can not only extend the life savings, but also significantly reduce the workload of lamp replacement, reducing the operating costs of lighting systems, management and maintenance becomes simple.
Both the thermal radiation source, or gas discharge light source, voltage fluctuations are a major cause of light damage. Therefore, the effective suppression of the fluctuations in voltage can extend the life of light sources.
Intelligent lighting control system can successfully suppress the surge voltage power grid, but also have a voltage limit and the conjugate stream functions of filtering, to avoid over-voltage and under-voltage damage to the light. The use of soft-start and soft turn-off technology, to avoid the impact of cu
rrent damage to the light. Through this method, the light source to extend the life span of usually 2 to 4 times.
1.3 to improve the working environment, improve efficiency
Good working environment is to improve the efficiency of a necessary condition. Good design and reasonable choice of light source, lamps and lighting quality control systems, can improve the quality of lighting.
Intelligent lighting control system dimming control panel module to replace the traditional lighting of the level switch control is an effective way to control the overall room illumination value, thereby enhancing the uniformity of illumination. At the same time, this control method used in electrical components have also solved the stroboscopic effect, will not create uncomfortable, confused, feeling eyestrain.
1.4 to achieve a variety of lighting effects
A wide range of lighting control, the same building can have a variety of artistic effect, for a lot of construction hyperchromic. Modern buildings, lighting is not simply to meet people on the visual effect of light and shade, they should have control of a variety of programs to make buildings more vivid, mor
e artistic, giving a wealth of visual effects and aesthetics. As an example of a project, building the exhibition hall, lecture hall, lobby, atrium, etc., if with intelligent lighting control system, according to different times, different uses, different effects, using the corresponding pre-set scene control, can achieve the wealth of artistic effect.
1.5 facilitate the management of maintenance
Intelligent lighting control system for the control of lighting based on the automatic control of modular-based, supplemented by manual control, preset lighting scenes to the parameters stored in the EPROM Digital, these information is very convenient to set up and replaced, so that building lighting management and maintenance easier.
1.6 have a high economic rate of return
Our reference point for the Shanghai region, from energy-saving lights and provincial estimates of the two made a come to this conclusion: with three to five years, the owner can recover the basic intelligent lighting control system to increase the total costs. Intelligent lighting control system can improve the environment and improve employee productivity and reduce maintenance and management costs, but also for the owners to save a substantial amount of costs.
2 intelligent lighting control system components
We know that the intelligent lighting control system of building control system is only one part of the. If you want to focus on the various control systems to the control center to control, then the control system must have the standard communication interface and protocol version. Although such a system integration is feasible in theory, but it is very difficult to put into practice. Thus, in engineering, intelligent management of our building a distributed system, distributed, that is relatively independent of each control subsystem, self-contained, the implementation of specific control, intelligent building management system control subsystem of the relative independence, self-contained, the implementation of specific control, intelligent building management system from the control subsystem is a signal collection and monitoring role.
At present, the intelligent lighting control system in accordance with sub-network topology, the following two forms, namely, bus and star-shaped structure-based hybrid. Both forms have the characteristics of a number of bus more flexibility, easy expansion, control of relative independence, lower costs; mixed some high reliability, fault diagnosis and rule out the simple, easy access to the agreement, transfer rate higher.
Engineering design, we consider the building of intelligent lighting control system as an independent subsystem, use of international standards and agreements of the communication interface text, into the intelligent building management systems. Intelligent lighting control system uses a distributed, distribution-based approach, that is, the dimming control unit is relatively independent, self-contained, non-interfering, through centralized management and information interfaces, and intelligent building management
system linked to the achievement of the building control center subsystem of the collection and monitoring of the signal. In short, the intelligent lighting control should be the main system is a centralized management, and the main trunk and information interface components consisting of the regional implementation of the same sample of control and signal networks; its subsystems should be a dimmer by the various types of modules , control panels, illumination detector dynamic and static and dynamic components consisting of detectors, respectively, of the regional implementation of the specific control of different networks, the main system and subsystems, such as between the components through the interface to connect, to achieve data transmission.

1.1 良好的节能效果
采用智能照明控制系统的主要目的是节约能源,智能照明控制系统借助各种不同的"预设置"控制方式和控制元件,对不同时间不同环境的光照度进行精确设置和合理管理,实现节能。这种自动调节照度的方式,充分利用室外的自然光,只有当必需时才把灯点亮或点到要求的亮度,利用最少的能源保证所要求的照度水平,节电效果十分明显,一般可达30%以上。此外,智能照明控制系统中对荧光灯等进行调光控制,由于荧光灯采用了有源滤波技术的可调光电子镇流器,降低了谐波的含量,提高了功率因数,降低了低压无功损耗。
1.2 延长光源的寿命
延长光源寿命不仅可以节省大量资金,而且大大减少更换灯管的工作量,降低了照明系统的运行费用,管理维护也变得简单了。
无论是热辐射光源,还是气体放电光源,电网电压的波动是光源损坏的一
个主要原因。因此,有效地抑制电网电压的波动可以延长光源的寿命。
智能照明控制系统能成功地抑制电网的浪涌电压,同时还具备了电压限定和轭流滤波等功能,避免过电压和欠电压对光源的损害。采用软启动和软关断技术,避免了冲击电流对光源的损害。通过上述方法,光源的寿命通常可延长2~4倍。
1.3 改善工作环境,提高工作效率
reactive翻译良好的工作环境是提高工作效率的一个必要条件。良好的设计,合理地选用光源、灯具及优良的照明控制系统,都能提高照明质量。
智能照明控制系统以调光模块控制面板代替传统的平开关控制灯具,可以有效地控制各房间内整体的照度值,从而提高照度均匀性。同时,这种控制方式内所采用的电气元件也解决了频闪效应,不会使人产生不舒适、头昏脑胀、眼睛疲劳的感觉。
1.4 实现多种照明效果
多种照明控制方式,可以使同一建筑物具备多种艺术效果,为建筑增不少。现代建筑物中,照明不单纯地为满足人们视觉上的明暗效果,更应具备多种的控制方案,使建筑物更加生动,艺术性更强,给人丰富的视觉效果和美感。以某工程为例,建筑物内的展厅、报告厅、大堂、中庭等,如果配以智能照明控制系统,按其不同时间、不同用途、不同的效果,采用相应的预设置场景进行控制,可以达到丰富的艺术效果。
1.5 管理维护方便
智能照明控制系统对照明的控制是以模块式的自动控制为主,手动控制为辅,照明预置场景的参数以数字式存储在EPROM中,这些信息的设置和更换十分方便,使大楼的照明管理和设备维护变得更加简单。
1.6 有较高的经济回报率
我们以上海地区为参照点,仅从节电和省灯这两项做过一个估算,得出这样一个结论:用三至五年的时间,业主就可基本收回智能照明控制系统所增加的全部费用。而智能照明控制系统可改善环境,提高员工工作效率以及减少维修和管理费用等,也为业主节省下一笔可观的费用。
