The development of the real estate industry sets off the field of building intelligent LED lighting energy saving
In the process of building lighting, in addition to the electricity consumed by the light source itself, the LED lamps will also generate corresponding heat. This part of the heat is also one of the main heat sources that constitute the largest energy consumption of the building's "air conditioning and heating". This series of facts not only showed people the high energy consumption of lighting, but also sounded the alarm for us. Currently, energy conservation and emission reduction are vigorously advocated throughout the country. As a large electricity consumer, architectural lighting is the first to become the "backbone force" in energy conservation.

Energy-saving led lighting is a systematic project, which involves many aspects such as the selection of lighting fixtures and intelligent control after completion. As an indispensable part of this system, led light source uses a simple way to achieve the expected energy-saving goals. Therefore, it has become the first choice for electrical engineers to save energy. At present, the light sources commonly used in civil buildings in my country are incandescent lamps, fluorescent lamps, and HID lamps. With the development of technology, some new light sources, such as fiber optic lighting, LEDs, etc., will gradually be adopted.
In the actual application process, various light sources have their advantages and disadvantages, and have a certain range of applications. Designers can flexibly choose matching energy-saving light sources according to the nature of the venue and the visual requirements of the personnel. For example, in offices, classrooms, meeting rooms and other occasions that do not require high illuminance, try to choose three-primary-color fluorescent tubes with high luminous efficiency, long life, and good color rendering. Because the efficiency of the straight tube lamp is better than that of the curved tube, and the smaller the tube diameter, the higher the light efficiency and the better the power saving effect. In addition, the combination of the three primary colors of red, green and blue becomes a warm white light. The light color of the tri-primary fluorescent tube is close to the sunlight, the light is comfortable, and the luminous efficiency is high, which meets the conditions of high-quality light source. In the case of satisfying the basic use, it can also achieve the effect of energy saving. This product should be the first consideration for designers.
As a new type of green semiconductor light-emitting diode, the LED product that has received widespread media attention now has an effective luminous rate higher than that of ordinary light sources under the same circumstances; and it does not contain harmful substances such as mercury and lead. Recycling, there is no ultraviolet and infrared in the spectrum, and no pollution to the outside world during production and use. The advantages of the light source are very obvious, and it is called the fourth-generation new green light source by the outside world. However, LED products also have some problems, such as uneven secondary optical distribution, color decay caused by poor heat dissipation, and problems with its optical fiber use. These problems have not been effectively solved in the industry, so they are affected during use. Some restrictions. But this does not mean that we cannot use the product. At present, such LED products can be widely used in areas where the contrast is not strictly required, such as urban landscape engineering, corridors in the community, indoor decoration, etc., to better utilize the characteristics of the LED light source and achieve the goal of energy saving. .
Advocate the use of intelligent lighting systems
These light sources provide our designers with a broad application space. Designers should fully understand the characteristics of various products and give full play to the advantages of LED energy-saving light sources to create a green and environmentally friendly lighting space for us.
As a simple and effective energy-saving measure, led energy-saving light source mainly plays a role in small buildings or home lighting. But in large public buildings, its energy-saving effect is a bit insignificant.
1. Programming on the integrated management platform can realize the automatic lighting control of the lighting circuit of each lighting zone, automatically adjust the indoor illuminance, and maintain it at the set value. Through the graphical interface, it can be flexibly modified by clicking the mouse. Switch control of lighting circuit and continuous adjustment of illuminance.
2. In the operation and management of public buildings, in order to achieve the effect of energy saving, the use of intelligent lighting systems is advocated. The lighting control system is an intelligent device, which is included in the building equipment automation system BAS (Building Automation System). Computer integrated system, complete daily operation and management work on the computer operating platform in the main control room. According to the daily scheduled schedule, annual scheduled schedule and schedule of holidays and specific dates in the integrated management software, time program programming is performed, and a full-year lighting schedule is provided.
3. After the system adopts this kind of intelligent control, it can control the lighting conditions of the entire building on the computer platform without being restricted by the light source and LED lamps. This can achieve the expected LED energy-saving target while improving the lighting utilization rate, saving a lot of power resources for the entire building.
4. The intelligent control system can also calculate the running time and illuminance level of the lighting led lamps according to the summary report provided by the software on the running time, illuminance value and other parameters of the led lighting system (to distinguish the lighting circuits in each lighting place), and Fully combine the working cycle schedule preset in the software, automatically switch the operation of each lighting circuit led lamps, so as to balance the running time of the lamps of each led lighting circuit, and perform regular maintenance and repair of the led lamps according to the summary report to extend the LED lamps Service life.
Reasonable layout of construction projects to fully improve lighting quality
5. Lighting energy saving is achieved on the basis of ensuring and improving the quality of lighting. When designing LED lighting, first determine the corresponding lighting scheme according to the different functions of various buildings. At present, the design scale of various types of buildings is getting bigger and bigger, the functions are getting more and more complicated, the facilities are getting more and more complete, and the interior decoration is getting more and more high-end. Residential buildings need to create a warm and comfortable feeling for people; office buildings need a bright and relaxed atmosphere; shopping malls need to increase the illuminance, illuminate the goods, attract customers' attention, and stimulate public consumption; dining places need to be quiet and increase appetite; Entertainment places need to make people relax and so on. Although these functions can be embodied by the architectural design, they largely depend on the coordination of the LED lighting design. Therefore, the architectural functions should be fully considered when determining the LED lighting design plan.
6. Determine reasonable illuminance standards according to the requirements of visual operations. Different places should be illuminated purposefully. The same room can be divided into working area, traffic area, non-important area, etc., in order to treat differently when choosing illuminance. When a certain part or several parts of the work area need high illuminance, the "zonal general lighting" method can be adopted. Places that require high illuminance can be equipped with local LED lighting; in rooms where the working position often changes, try to use a flexible lighting solution that can adjust the position of the LED lamp. Natural light should also be fully utilized. During the day, natural lighting is the mainstay. When natural light is not enough, constant artificial lighting is supplemented so that the natural light from windows and indoor artificial lighting can be properly and reasonably coordinated to form a good lighting environment. To save energy.
Energy-saving architectural lighting runs through the entire process of project design, construction, and commissioning. Therefore, the energy-saving potential of the LED lighting system is still quite large. When designing the lighting system, choosing reasonable lighting products, advanced intelligent lighting control systems, and adopting scientific and standardized management in the later daily operation, starting from various channels, can effectively alleviate the current situation of power shortage in my country , To achieve the goal of LED energy saving.
