1 The advantages of the use of the intelligent lighting control system
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 lamp 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 current 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, more 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 onlyone 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 利用智能照明控制系统的优势
1.1 良好的节能效果
智能照明控制系统的主要目的是节约能源,智能照明是用“预先设定的“控制模式和控制元件的控制系统,在对不同时间的不同光照度进行准确的设置和合理的节能管理。这种自动调整照明方式,采取充分利用室外的自然光,只在必要时当灯或光所需的亮度有要求时,用最少的能源,以确保所需的照明度,节能效果十分明显,通常是超过30%不等。此外,智能照明荧光灯调光控制灯等,由于使用荧光灯电子镇流器有源可调谐滤波器技术,减少了谐波含量,提高了功率因数,降低了低压无功损耗。
1.2 延长光源寿命
照明光源不仅可以延长使用寿命,而且还大大减少更换灯泡的工作量,减少照明系统的运作成本,使得管理和维修变得简单。 无论是热辐射光源或是气体放电光源,电压波动是光损伤的重要原因。因此,有效的制止波动电压可以延长光源的寿命。 智能照明控制系统可以成功地抑制电源网络的浪涌电压,但也有限制电压和共轭电流滤波的功能,以避免过电压和欠电压损坏光源。通过使用软启动和使用软关断技术,可以避免损害到光电源。通过这种方法,光源寿命通常可延长为2至4倍。
1.3 改善工作环境,提高工作效率
良好的工作环境,是提高效率的一个必要条件。良好的设计和光源,灯具和照明质量控制系统的合理选择,可以提高照明质量。 智能照明控制系统使用的调光控制面板模块,用以取代传统的液位开关控制照明是一种有效的方式来控制整个房间照度值,从而提高照度均匀性。同时,这种控制方法在电器元件使用,也解决了频闪效应,也不会产生不舒服的,混乱的感觉和眼睛疲劳。
1.4 实现了多种灯光效果
一个广泛的照明控制,同样的建设可以有不同的艺术效果并为建筑增色不少。现代建筑,照明不仅是为了履行对光影的视觉效果,设计师们应该有多种方案的控制,使建筑物更加生动,更加美观,给人一种视觉效果和美学的财富。作为一个工程实例,例如展厅,报告厅,大堂,中庭等,如果能利用智能照明控制系统,对不同时期,不同用途,不同的效果采用相应的预设置场景控制,就可以实现丰富的艺术效果。
1.5 便于维护管理
智能照明控制系统的控制基础为自动照明控制模块,由人工控制为辅,把预置的灯光场景的参数存储在EPROM中,这些信息可以非常方便的设置和更换,使建筑照明管理和维护更加容易。
