Comprehensive analysis of the status quo and comprehensive advantages of China's intelligent lighting market
The following three aspects introduce the characteristics of intelligent lighting control systems and related products:
First, the control content and scope:
Time control
Different electrical control of the lighting fixtures for normal operating conditions in each zone is achieved by electrical components such as a clock manager.
2. Lighting brightness automatic adjustment control
Through the electrical components such as each dimming module and illuminance dynamic detector, the automatic dimming control of the lighting fixtures for normal working conditions in each area under normal conditions is realized, so that the illumination in the area does not follow the sunshine and the like. Changes in factors change and remain at or around the preset value of illumination.
3. Scene control
The scene switching control of the illumination area in the normal working state in each area is performed by each of the electric components such as the dimming module and the control panel.
4. Automatic switch control
Through the electrical components such as each dimming module and motion detector, automatic switching control of the lighting fixtures in normal working conditions in each area is realized.
5. Control of emergency lighting
Refers to the control performed by the intelligent lighting control system for emergency lighting in a special area. By controlling the electrical components such as the dimming module of each emergency lighting control, it is possible to abandon the dimming control of the lighting fixtures in each area in an emergency state. Make emergency lighting in an accident state 100%.
6. Manual remote control
In the normal state, the infrared remote control is used to realize manual control and regional scene control of the lighting fixtures in each area.
The scope of intelligent lighting control system control mainly includes the following categories:
Urban area lighting, street lighting; computer centers, hospitals, military and other important departments; home foyer and atrium, walkways and elevators and other common parts; in addition, the overall and facade lighting of large buildings are also provided by the intelligent lighting control system to provide switching signals control.
Second, the reliability of intelligent lighting control system:
The reliability of the system involves the structure of the system, the controller and the fault tolerance measures of the system.
1. The structure of the control system has been continuously improved with the development of computer communication technology, and has evolved from the fourth generation of distributed control to the fifth generation of distributed control.
The characteristics of distributed control are that the controller is highly modular in structure, highly dispersible in layout, highly autonomous and intelligent in controller performance, and has self-diagnosis and fault tolerance. Information is transmitted through a simple bus according to standard protocols. Transmission, so the distributed system structure is very reliable and simple, design, installation, operation, maintenance, and very convenient.
2. The reliability of the lighting controller is an important part of the control system. The reliability of the key components, circuit design and protection measures of the controller will directly affect the safety and stability of the lighting operation.
3. In addition to the system structure and the reliability of the controller, it is necessary to take some preventive measures to further improve the safety and reliability of the system. For example, if the WatchDog monitoring software is set on the network, it is checked whether the online communication of each controller on the network is normal. Once a certain controller communication is found to be abnormal, the system will automatically dispose of it.
Third, the comprehensive advantages of intelligent lighting control system:
1. Good energy saving effect
In China's current macroeconomic construction, the task of saving energy and energy is becoming more and more urgent. The intelligent lighting control system uses various intelligent setting control methods and control components to accurately set and manage the illumination of different environments at different times to achieve maximum energy saving effect. This method of automatically adjusting the illuminance makes full use of the natural sunlight outside, and only when necessary, the luminaire is turned on to the required brightness, and the required illuminance level is ensured with the least energy, and the power saving effect is very obvious, generally up to 30%. the above. In addition, the intelligent lighting control system can also perform dimming control on fluorescent lamps, etc. Since the fluorescent lamp adopts the dimmable electronic ballast with active filtering technology, the harmonic content is reduced, the power factor is improved, and the low voltage is reduced. Power loss, also achieve power saving purposes.
2. Extend the life of the lamp
Extending the life of the lamp not only saves a lot of money, but also greatly reduces the maintenance workload of replacing the lamp, reduces the failure rate and operating cost of the lighting system, and makes management and maintenance much easier.
Whether it is a thermal radiation source or a gas discharge source, fluctuations in the grid voltage are a major cause of source damage. Therefore, the intelligent lighting control system can effectively suppress the fluctuation of the grid voltage, and the functions of voltage limitation and yoke filtering can effectively avoid the damage of the overvoltage and undervoltage to the luminaire. In addition, the intelligent lighting control system also has soft start and soft turn-off technology to avoid damage to the light source caused by the inrush current. Through the above method, the life of the luminaire can usually be extended by 2 to 4 times.
3. Improve lighting quality
Good lighting quality is a necessary condition for improving work and learning efficiency.
The intelligent lighting control system replaces the traditional flat switch control luminaire with the dimming module control panel, which can effectively control the overall illuminance value in each room, thereby improving illuminance uniformity. At the same time, the electrical components used in this control method also solve the stroboscopic effect, and will not cause people to feel dizzy and tired eyes.
4. Achieve a variety of lighting effects
In modern architecture, lighting is not simply to meet the visual and dark effects of people. It should also have a variety of control schemes to make the lighting of the building more artistic, so that people can appreciate the beautiful visual effects. If the intelligent lighting control system is equipped in the exhibition hall, lecture hall, lobby, atrium, etc. in the building and the external contours, the corresponding pre-set scenes can be controlled according to different time, different purposes and different effects, so that a rich Artistic effect.
5. Easy management and maintenance
The intelligent lighting control system controls the lighting mainly with modular automatic control. The manual control is supplemented. The parameters of the lighting preset scene are stored in the EPROM digitally. The setting and replacement of these information is very convenient, plus the life of the lamp. The greatly improved, making lighting management and equipment maintenance easier.
6. Higher economic returns
According to experts' estimates, it is only from the two aspects of saving electricity and saving lamps: in three to five years, the owner can basically recover all the expenses added by the intelligent lighting control system. The intelligent lighting control system can improve the lighting environment, improve employee productivity and reduce maintenance and management costs, and save the owner a considerable amount of money.
