Renovation of energy-saving lighting in old buildings
The lighting system is the second largest energy consumption in buildings, especially in hotels, restaurants and entertainment venues. According to statistics, the current global lighting energy consumption accounts for about one-fifth of the entire electricity resource consumption, so starting from lighting energy saving can bring invaluable contributions to energy saving and emission reduction.
In recent years, with the advancement of science and technology, people have put forward higher requirements for lighting energy saving and scientific management, making lighting control more and more important in the field of intelligence, and for the comfort and personality of artificial lighting environment. The needs of chemical, safety and energy saving are becoming more and more prominent. Now new building builders are also aware of the importance of intelligent lighting. In the renovation of old buildings, the renewal of lighting systems is also in the first place.
Why do old buildings need smart lighting
Power saving is a major advantage of the intelligent lighting control system. The traditional lighting operation in public areas of buildings can only be controlled by simple switches, turning off the lights during the day and turning on the lights at night. The intelligent lighting control system uses various "preset" control methods and control components to accurately set and reasonably manage the illuminance of different environments at different times and achieve energy saving.
This method of actively adjusting the illuminance makes full use of the outdoor natural light, and only turns on the lights or lights up to the required brightness when necessary, and uses the minimum power to ensure the required illuminance level. The effect of saving electricity is very significant, usually up to more than 30%. In addition, because LED is a new generation of light source, it has a series of characteristics such as low voltage, low power consumption, small size, and fast response. It is more efficient than traditional light sources and is an excellent green lighting source. Coupled with intelligent control, it can do To be more energy-efficient, it is the first choice for the renovation of old buildings to replace old light sources. Such as central dimming control: through centralized central control, dimming, and punctual closing of LEDs; sunlight compensation control: make full use of natural light, reduce LED lighting time and brightness; Off; event control: Pre-programmed with special events to accurately manage lighting.
Smart lighting not only refers to smart lighting to reduce energy consumption, but also includes a variety of modern technologies such as sensing, communication, and the Internet of Things. Even if a single LED lamp adopts intelligent green LED lighting technology, it is only one point, and its function is relatively limited; if the network control of multi-point LED lamps can be completed, so that the lighting management control can be centralized and centralized, that is, the main control computer can control the network. It is of great significance to give full play to the advantages and potential of intelligent green LED lighting technology.
As an integral part of modern building technology, the intelligent lighting control system has complete control protocols and control methods, perfect man-machine interface, self-diagnosis and prompting of faults in intelligent control software; in hardware, it has a variety of communication capabilities method. Such as wireless, power carrier, visible light, infrared light. Intelligent lighting control is achieved through intelligent control, and it can be linked with other systems. Intelligent lighting can be linked with other systems, such as BA system, monitoring and alarm system, garage card swiping system, and then improve the management level and reduce maintenance costs.
On the other hand, the intelligent lighting control system has a variety of lighting control methods, which can make the same building have a variety of artistic functions, adding a lot to the building. In modern buildings, lighting is not only to satisfy everyone's visual effect of light and shade, but also to have a variety of control schemes to make the building more vivid, more artistic, and give people a rich visual effect and beauty.
Typical smart lighting system products
The advancement of technology has made people's needs for high-quality light sources more and more diverse. By adjusting the light, a warm and comfortable living environment is created. At this stage, there are many LED lighting dimming control systems on the market, considering the coverage of the application. Can be divided into three categories:
1. The C-BUS system is an intelligent control system that uses unshielded twisted pair as the bus carrier and is widely used in the comprehensive control and comprehensive energy management of lighting, air conditioning, fire detection, entrance and exit, security and other systems in buildings. . Its product design and production technology meet Australian and European electrical safety and electromagnetic compatibility specifications.
2. The i-BUS system adopts the EIB (Electrical Device Bus) standard, which can control a variety of control objects: lighting on and off and dimming, electric window cloth and sunshade, air conditioning temperature control and floor heating, background music, smart home appliances, optional Video intercom security and defense linkage and so on.
3. DALI (Digital Addressable Lighting Interface) intelligent control system, DALI is a dedicated lighting control protocol, in addition to defining the communication method between the electronic ballast and the controller, it allows the communication between the controller and the lighting fixtures , DALI technology also solves the control, response and networking of each LED luminaire. In the digital control signal of lighting, DALI has the unparalleled advantages of other lighting digital control signals, and it is also the mainstream and open international standard for the application of digital control signals in the lighting industry.
Lighting is needed in places where there are people. The lighting design of old buildings with high energy consumption is no longer suitable for today's society, and the more prosperous the society, the greater the demand for lighting. The contribution of energy saving cannot be underestimated. In addition to energy saving, the major advantages brought by the intelligent lighting control system are that one is humanized, and the other is that the protection cost of lighting equipment is greatly reduced, which has serious implications for building a conservation-minded society.
