Digital homes, as a gathering place for human communication, networking, building materials, security, and home industries, have received great attention from the society.
Smart Lighting Market Status
Foreign related products operate smart lighting as part of their smart products, positioning the high-end, creating a high-profile situation. Like the home appliance market in the 1980s and 1990s. However, with the rapid development of the domestic economy and the maturing of technology, some international brands such as Dynalite, Lutron, WIELAND, e-bfb, etc. have entered the Chinese market, prompting the development of the industry. In the 21st century, domestic intelligent lighting manufacturers and merchants have mushroomed rapidly. Emerging from dozens of companies such as Ruilang, Baifen Lighting, Tsinghua Tongfang, Sobo, and Haier, smart lighting has entered a new stage of development.
The following describes the characteristics of intelligent lighting control systems and related products in three aspects:
First, control content and scope:
1, time control
By means of electrical components such as a clock manager, different time control of the lighting fixtures used in the normal operating state in each area is achieved.
2, automatic control of lighting brightness adjustment
Through the electrical components such as each dimming module and illuminance detector, the automatic dimming control of the lighting fixtures used in the normal working state in each region under normal conditions is realized, so that the illumination in the region will not be affected by sunlight, etc. Changes in the factors change, and always remain around the preset value of illumination.
3, scene control
Through the electrical components such as each dimming module and control panel, scene switching control of the lighting area in the normal working state in each area is performed.
4, automatic switch control
Through the electrical components such as each dimming module and the dynamic and static detectors, the automatic lighting control of the lighting fixtures in the normal working state in each area is realized.
5, the control of emergency lighting
Refers to the intelligent lighting control system for the implementation of the control of emergency lighting within a special area, through the control of each emergency lighting control of the dimmer module and other electrical components, to achieve in the emergency state of the district lighting fixtures to give up dimming control Make emergency lighting in an accident reach 100%.
6, manual remote control
In the normal state, through the infrared remote controller, manual control and area scene control of the lighting fixtures in each area are realized.
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 sectors; home halls and atriums, walkways and elevators and other common parts; In addition, the overall size of large buildings and Facade lighting is also controlled by intelligent lighting control systems that provide switching signals.
Second, the reliability of intelligent lighting control system:
The reliability of the system involves the system structure, fault-tolerant measures of the controller and system.
1. The control system structure has been continuously improved with the development of computer communication technology. It has evolved from the fourth generation of distributed control methods to today's fifth generation of distributed control methods.
The characteristics of distributed control are that the controller is highly modular in structure, highly distributed in layout, highly autonomous and intelligent in controller performance, and has self-diagnosis and fault-tolerant functions. The information is processed through a simple bus according to standard protocols. Transmission, so distributed system structure is very reliable and simple, design, installation, operation and maintenance are also very convenient.
2. The reliability of the lighting controller is an important part of the control system. The reliability of the key components of the controller, circuit design and protection measures will directly affect the safety and stability of the operation of the lighting fixture.
3, in addition to the system structure, controller reliability, to maintain reliable and stable operation of the control system must take some preventive measures to further improve the system's safety and reliability. If WatchDog monitoring software is set on the network, check whether the online communication of each controller on the network is normal. If a controller communication is abnormal, the system will automatically handle it.
Third, the comprehensive advantages of intelligent lighting control system:
1, good energy-saving effect
At present, China's macroeconomic construction, the task of saving energy is becoming more and more urgent. The intelligent lighting control system uses various “smart settings†control methods and control elements to accurately set and manage the illuminance of different environments at different times to achieve maximum energy savings. This way of automatically adjusting the illuminance makes full use of the outdoor natural sunlight. Only when necessary, the luminaire is turned on to the required brightness, and the required illuminance level is ensured by using the least amount of energy. The power saving effect is very obvious, generally up to 30%. the above. In addition, intelligent lighting control system for fluorescent lamps can also be dimming control, because the fluorescent lamp uses an active filter technology adjustable optical electronic ballast, reducing the harmonic content, increasing the power factor, reducing the low voltage The power loss also achieves the purpose of power saving.
2, extend the lamp life
Extending lamp life can not only save a lot of money, but also greatly reduce the maintenance workload of replacement lamps, reduce the failure rate and operating costs of the lighting system, and make management and maintenance easier.
Whether it is a heat radiation source or a gas discharge light source, fluctuations in grid voltage are a major cause of light source damage. Therefore, the intelligent lighting control system can effectively suppress the fluctuation of the power grid voltage. Through the system's function of voltage limitation and yoke filtering, it effectively avoids damage to the lamps caused by over voltage and under voltage. In addition, the intelligent lighting control system also has a soft start and soft turn-off technology to avoid the impact of the impact current on the light source. By the above method, the life of the lamp can usually be extended by 2 to 4 times.
3, improve the 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 lamps with the dimmer module control panel, which can effectively control the overall illuminance value in each room, thereby improving illumination uniformity. At the same time, the electrical components used in this control method also solve the stroboscopic effect, and will not make people feel drowsy and eye fatigue.
4, to achieve a variety of lighting effects
Modern architecture, lighting is not simply to meet people's visual brightness and darkness, but also should have a variety of control programs, so that the lighting of the building more artistic, so that people appreciate the beautiful visual effects. If intelligent lighting control systems are equipped in the exhibition halls, lecture halls, lobbies, atriums, and external contours of buildings within the building, different preset uses of different time, different purposes, and different effects can be used to achieve control. Artistic effect.
5, convenient management and maintenance
Intelligent lighting control system control of lighting is mainly based on modular automatic control, supplemented by manual control, lighting preset scene parameters are stored digitally in the EPROM, the setting and replacement of these information is very convenient, plus the lamp life Greatly improved, making lighting management and equipment maintenance easier.
6, higher economic returns
According to experts' calculations, only from the two aspects of saving electricity and saving lamps and lanterns: in three to five years, the owner can basically recover all the increased costs of the intelligent lighting control system. The intelligent lighting control system can improve the lighting environment, improve the staff's work efficiency, and reduce maintenance and management costs. It also saves the owner a considerable amount of money.
