With the development of economic construction and the continuous improvement of the material and cultural level of society, people are increasingly pursuing high-quality work and living environment. In the modern intelligent office building, the lighting has far exceeded the basic needs of the original lighting, and began to pursue the beauty enjoyment brought by the lighting art; pursue the overall control effect of lighting and other related equipment and systems; pursue the energy-saving effect of lighting control . Intelligent lighting control products are the new generation of lighting control products that have emerged as the times require. It is a new point of indoor and outdoor environmental lighting, providing a new way for lighting control of intelligent office buildings.
1 The positioning of intelligent lighting control system in modern intelligent building 1.1 is the integrated system of lighting control and power supply. The new system and the original building automation system control lighting of the intelligent building are the biggest difference, that is, the building automation system only performs weak electricity. Control, the actuator uses a contactor to switch the lighting circuit; the intelligent lighting control system is an inseparable system that integrates weak current control and high-voltage power supply: it is self-contained and directly supplies power to the lighting load. control. Therefore, for intelligent lighting control systems, users can not only look at the control characteristics, but also pay attention to their performance as electrical equipment. In particular, they should pay attention to whether they have passed the safety certification as the core product quality certification. 31.2 is the lighting control system. Several intelligent building bus integrated systems or centralized control systems with touch screens on the market also have simple environmental dimming functions. From the perspective of ensuring the safety and reliability of the lighting system, the author believes that the independent intelligent lighting control system with integrated functions of other systems is more integrated than the integrated intelligent building bus integrated system or the centralized control system with touch screen. Applicable: The touch screen centralized control system is mostly used in reporting halls, large venues, etc., and is rarely used for the control of the entire building: intelligent building bus integrated systems, such as EIB (Electrical Installation Bus) systems, are in intelligent buildings. A system that combines various control function sets *32*(32) through the same bus. However, the practice of control system engineering tells us that blind pursuit of large integration may not be the direction, and that it is misleading to think that big integration is the latest technology. The development of control must balance the proper dispersion and care of traditional operating habits. Affected by these two principles, people tend to have independent control over lighting.
2 Application examples of intelligent lighting control system in modern intelligent buildings In recent years, more and more new intelligent buildings in China have adopted intelligent lighting control systems. Some are controlled by the whole building system, and some are only controlled by some places.
2.1 Using Intelligent Lighting Control System in China Telecom Communication Command Center China Telecom Communication Command Center is located in Beijing Financial Street, with 19 floors and 3 underground floors. Through fierce bidding, China Telecom selected LUTRON Electronics. Intelligent lighting control system.
2.1.1 Solution Selection When making a solution selection, the first problem is to select the system according to the needs. There are two options to choose from: 1 use the GRAFIKEye 3000/4000 series; 2 use the GRAFIK5000/6000 series: the GRAFIKEye3000/4000 series and the ORAFIK5000/6000 series have different design ideas. The former applies to the complete independent decentralized control of each site; the latter applies to a multi-site building with a lighting monitoring center, or when there are complex overall control requirements for lighting.
There are 126t of intelligent lighting control places in China Telecom Communication Command Center, including 66 dimming control places and 60 intelligent switch control places - requiring the control center to centrally monitor the parallel person building automation system. According to the scale of this system, the GRAFIK 6000 series is selected. The series is designed by LUTRON for high-rise buildings or large commercial spaces. It is especially suitable for centralized management and decentralized control of the entire building.
2.1.2 System Features 2.1.2.1 The system consists of four major components (see the following figure): 1 The upper computer and control panel placed in the central control room. 2Distribution discs and soft switch discs distributed in the distribution areas of each layer. 3 Control and interface components distributed in each place of use. 4 communication links throughout the building.
2.1.2.2 The system is a combination of centralized and decentralized systems. Its communication management is concentrated on the control panel. Control functions are distributed to each disc and loop.
2.1.2.3 Make full use of Lutron GRAFIK system power components to adjust the optical disc, switch panel integration, high reliability, lighting power supply function and other characteristics, the main lighting of the entire building into the same system, unified management, centralized monitoring.
2.1.2.4 For the characteristics of the user, Lutron's unique lighting controller is used in small places. The Lutron 3600 series lighting controller is characterized by a combination of strong and weak electricity, which is equivalent to a combined multi-channel dimmer switch, which is used for both weak current control and strong power supply. On this controller, not only the LED (Light Emitting Diode) light column intuitively displays the illumination brightness of a loop or a light zone, but also has a window and scrolling menu on the controller for the user to set the light intensity, scene, and fade out. (scene switching) time, etc., very intuitive and convenient.
The controller also integrates an infrared receiver that can be operated remotely using an infrared remote control.
Lutron 3600 series can adjust lighting parameters in the lighting control center and on-site, set lighting scenes, can meet the requirements of large and small buildings in a building, and reduce the cost of the system.
2.1.2.5 The building has requirements for linkages with other control equipment or other systems in many locations. For example, in the main control room through the RS-232 interface and BMS (Building Automation Management System) connection; in the auditorium and multi-purpose hall, through the contact control interface and AMX touch screen control system linkage, and then with the conference equipment, stage equipment linkage; In other places where communication with the conference equipment is required, a linkage interface is also added. It reflects the powerful system integration capability of Lutron Lighting Control System.
2.1.2.6 Pay full attention to the characteristics of fluorescent lighting and energy-saving lamps (ie compact fluorescent lamps) in the office building to achieve continuous dimming control of such light sources. Considering the ~1V voltage controlled dimmable electronic ballast in the Chinese market is relatively cheap, choose the corresponding fluorescent light interface.
2.1.2.7 The Lutron 3600 controller and various scene control panels are equipped with an infrared receiver, which can accept the remote control distance of 13.5m signal, and more infrared remote control is used.
2.2 In the ICBC Head Office building using intelligent lighting control system 2.2.1 program selection ICBC Head Office building only designed in several public events theater stage lighting electrical design Ren Hong (Beijing Architectural Design and Research Institute 100045) electricity, control and Problems to be aware of in engineering design.
In recent years, with the development of China's socialist spiritual civilization construction, cultural facilities across the country have developed rapidly, and many conference centers, theaters, and studios have been newly built and rebuilt. Among them, the stage lighting system is an indispensable part of performance venues such as theaters and studios. It changes the time, place, space, atmosphere, character feelings, beauty and ugliness in the program through changes in light intensity, light color, effect and balance. Show it out. The rationality of the layout of the stage lighting and the performance of the lamps and lanterns will directly affect the performance of the various types of dramas and play an important role in the perception of people.
Stage lighting, you are highlighting the four elements of vision, realism, aesthetics and performance. In the theater, the vision is to make the audience see the scenes on the stage well, that is, to correctly understand the intent of the creation of the drama and the dance; the realism makes the stage look like a real life scene, so that the audience is immersive. Sense, that is, the effect of lighting truthfully; aesthetics is to make the stage beautiful, so that the audience can get a pleasing feeling in line with the scene; the performance is to render the thoughts and feelings of drama, dance, etc., mainly relying on harmonious scenes and lights to set off .
The site adopts a dimming control system, such as a large auditorium, a multi-purpose hall, an exchange lecture hall, a large conference room, and an exhibition hall. In this way, the Lutron GRAFIKEye 3000/4000 series is selected, which simplifies the system requirements and reduces the system cost.
2.2.2 System Features 2.2.2.1 This series of products mainly consists of controller, dimming / switch panel, accessories / interfaces.
3000/4000 series lighting controller and loop selector on the power panel. Users can set and adjust lighting parameters independently according to their own wishes in various lighting places, intuitively and easily self-programming, self-setting scenes, and local control. There is no need to rely on dedicated tools and professionals in the background, not to rely on manufacturers. This feature makes the design of the stage lighting equipment and the design of the power distribution in each place should provide more convenient conditions for the stage lighting equipment suppliers. Therefore, in the electrical design of the theater, we should fully understand the various requirements of the stage lighting for the power distribution system, and work closely with the characteristics of the building structure in order to do a good job in design work. Let's talk about some experiences and opinions in the actual situation of the stage lighting distribution design in China's Pingju Theatre and Chang'an Grand Theatre.
1 The success of the stage lighting design of the theater lighting is based on whether the treatment of the stage lighting is appropriate. The stage lighting not only illuminates the actors, but also allows the audience to see facial expressions, expressions and movements. More importantly, it is to fully utilize the lighting technology and mobilize the lighting operation to enhance the artistic effect and make the audience feel immersive.
1.1 Stage lighting installation parts, functions and lighting configuration Stage lighting is mainly divided into two types according to its use functions: dimmable dimming road; non-dimmable direct-discharge loop.
Stage lighting methods are generally divided into three types: fully independent decentralized control becomes possible. It can be a complete system in one place, reducing the requirements of the staff, making the user particularly convenient.
2.2.2.3 The lighting controller is divided into two series, which are suitable for the lighting controller (ie 3000 series) used in small places, integrating strength and weak electricity, both for weak current control and for strong electric power supply. If the site area is large and there are many lighting circuits, a strong and weakly separated lighting controller and a tuned disc system (ie, the 4000 series) should be used. The optical disc replaces the traditional switchboard, and the lighting controller performs weak current control and operation. The two are connected by a communication cable. 3 GRAFIKEye3000/4000 series lighting controller integrates the system's microprocessor and programmer, especially suitable for Decentralized, independent use, especially suitable for the transformation of old places.
