Energy saving transformation of the old building from the first energy consumption under the knife

[introduction] lighting system is building, especially the second largest energy consumption of hotels, restaurants, and entertainment.

　　Lighting system is a building, especially in hotels, restaurants and entertainment places of the second major energy consumption, which is characterized by various types of lamps and lanterns, variety, a small single lamp power. According to statistics, the current global lighting energy consumption accounts for about 1/5 of the total electricity consumption, so starting from the energy-saving lighting to be able to contribute to the energy saving and emission reduction.

　　In recent years, with the progress of science and technology, people lighting energy conservation and scientific management of proposed higher requirements, making the lighting control in the field of intelligence is becoming more and more important, the artificial lighting luminous environment comfortable, personalization, safety, energy saving, etc. the demand have become increasingly prominent. At present, the construction of the new building are also aware of the importance of intelligent lighting, in the old building renovation, lighting systems have also been updated in the first place.

　　Why the old building needs intelligent lighting

　　Energy saving is the biggest advantage of intelligent lighting control system, traditional building regional public lighting mode, only using a simple switch control, turning off lights in the daytime, night lights. Intelligent lighting control system with a variety of different "pre setting" control mode and control components, the different time of the different environment of light illumination for accurate setting and reasonable management, to achieve energy saving.

　　The automatic adjustment of the illumination, make full use of the natural outdoor light, the lamp or light to the required brightness only when necessary, use the least energy to ensure that the required illumination level, energy-saving effect is very obvious, usually ranging from more than 30%.In addition, because the LED as a new generation of light source, with low voltage, low power consumption, small volume and quick response a series of characteristics, higher efficiency than the traditional light source, is a good green lighting source, coupled with the intelligent control can do more energy-saving, is old buildings reconstructed and replaced the old light source preferred. Such as adjustable central optical control: through centralized control, dimming, timing closure LED; daylight compensation control: make full use of natural light, reducing the LED lighting time and brightness; infrared induction: the human infrared sensor to achieve light, people walk lamp; event control: through special events programming, precise management of lighting.

　　Not just energy saving

　　Intelligent lighting is not only refers to the intelligent lighting to reduce energy consumption, but also covers a variety of modern technology, such as sensing, communication, and Internet of things. A single LED lamp even after the adoption of green intelligent LED lighting technology, only a point, the effect is relatively limited. If we can realize multi-point LED lamps and lanterns, the networked control, the centralized lighting control, namely, by the main control computer in the network lighting equipment for control and management, and timely feedback to the operator, to give full play to the intelligent LED green lighting technology advantage and potential has important significance.

　　Intelligent lighting control system as a modern building technology, a part, in the intelligent control software, complete control protocol and control method, perfect man-machine interface, fault self diagnosis and prompt; in hardware, with multiple communication capabilities. Such as wireless, power line carrier, visible light, infrared light. Through intelligent control to realize the intelligent lighting control, and other system linkage intelligent lighting can control with linkage to other system, such as BA system, alarming, monitoring and controlling system, garage card system, so as to improve the management level, reduce maintenance costs.

　　On the other hand, intelligent lighting control system in a variety of lighting control mode, the same building can have a variety of artistic effect, the building considerably. Modern buildings, lighting is not only for meeting people's visual effects of light and shade, should have more control of a variety of programs, to make buildings more vivid, more artistic, to enrich the visual effects and aesthetic.

　　Typical intelligent lighting system products

　　The progress of technology, making people of high-quality light source demand more and more diverse, by adjusting the light to create a warm, comfortable living environment, now LED lighting adjustment in the market stage light control system more, from the use of the coverage to consider can be divided into three categories:

　　1, the C-Bus system is a kind of unshielded twisted pair as the carrier of the bus. It is widely used in building lighting, air conditioning, fire detection, intelligent control system of integrated control of the entrance, security system and integrated energy management. Its product design and manufacturing processes to meet the standards of electrical safety and electromagnetic compatibility in Australia and europe.

　　Using EIB (Electrical Installation Bus) standard 2, i-BUS system can the various control objects of control: lights on closing and dimming, electric curtains and shading, air conditioning temperature control and heating, background music, smart appliances, video intercom and anti interaction and so on.

　　3, Dali (digital addressable lighting interface) intelligent control system, Dali is dedicated lighting control protocol, in addition to defining the means of communication between the electronic ballast and the controller that allows communication between the controller and the lighting lamp, Dali technology also addresses the control of each LED lamp, feedback and networking. In the digital control signal of lighting, DALI has the incomparable superiority of other digital control signals, and it is also the mainstream of the digital control signal applied in the lighting industry.

　　Conclusion: local people need lighting, old buildings energy consumption in buildings lighting design is not suitable for the modern society, and the more advanced a society of lighting demand is even greater, lighting monomer although modest, but the influence to the society, the energy-saving contribution should not be overlooked. Intelligent lighting control system to bring the greatest benefits in addition to energy saving, the first is to achieve a humane, two is to make the maintenance cost of lighting facilities greatly reduced, the construction of a conservation minded society is of great significance.
