In order to reduce the energy consumption of light sources and improve the utilization of energy by lighting, in the past 30 years, countries around the world have invested a large amount of money to develop a variety of light sources to replace incandescent lamps, such as nowadays for a large number of indoor lighting. Fluorescent lamps (energy-saving lamps, fluorescent lamps, etc.), low-voltage tungsten halogen lamps, and semiconductor light source (LED) lamps have been developed in recent years. The emergence and application of these light sources greatly reduce the energy consumption of lighting. With the development of emerging light sources, strengthening the construction of lighting control systems will further reduce energy consumption.
Application energy consumption can not be ignored. Lighting energy consumption is divided into two categories, one is the energy consumption of the light source itself, also called hard energy consumption; the other is application energy consumption, also called soft energy consumption. In human life activities, reducing the energy consumption of the light source does not solve all the problems of lighting energy consumption. Because the energy consumption of lighting fixtures (including light sources and electronic rectifiers, etc.) is only a parameter of lighting energy consumption. Inefficient use of energy and unreasonable use of energy is another aspect of lighting energy consumption. The energy consumed by such lighting appliances is referred to as ineffective energy consumption. The phenomenon of inefficient energy consumption is common in real life, and its survival form is also complex. The main performances are as follows: First, in some public spaces such as underground parking garages and public aisles, whether there is a car or not. The car, whether it is day or night, or no one, no one, the lights are always on, and the inefficient energy consumption is happening all the time. Second, when designing some indoor places, such as office space, public aisles, restrooms, parking garages, computer rooms, warehouses, etc., according to the national illumination standards, the actual illumination of the design often exceeds the national standard. Third, during the daytime, the natural light is radiated to the room, and its light intensity is always uneven. The light near the window (lighting surface) is stronger, and the farther away from the window (lighting surface), the darker the light, to solve this problem. One of the most common methods is to evenly add a certain number of lights to the ceiling of the room. This uniform addition is very meaningful for evening lighting. However, in the daytime, this method produces an unreasonable use in the area of ​​light intensity while filling the dark area. That is to say, the light is often turned on in the area where the light is strong, and thus the inefficient energy consumption is generated. Fourth, most of the existing lighting control systems are not capable of dimming control of energy-saving light sources for technical reasons. Therefore, in some places where lighting control systems are widely used, high energy is still being used to create various special light environments. The consumption of incandescent lamps increases the energy consumption. Therefore, the development of lighting energy management control technology, we have a further understanding of lighting energy consumption issues, clear the direction of our system energy saving. Lighting energy management and control technology can further solve the problem of ineffective energy consumption based on the full use of energy-saving light sources and energy-saving lighting appliances.
Intelligent management of energy-saving effects Highlighting energy-saving light sources means that all energy-saving light sources and energy-saving lighting appliances are used throughout the lighting system. These light sources and appliances (electronic devices) are subject to network intelligent control systems. The electric light source has both performance indicators of electricity and light, and the performance indicators of these two aspects are closely related. However, as a light source, it is mainly a performance index of light, and the indicator of electricity is often more important than its influence on light performance. In practical engineering applications, in order to make the system reach the illumination index within the basic life and offset the attenuation of the light source, the luminous flux index of the selected lighting is always properly improved. Therefore, how to solve this problem through system control technology worthy of study. According to statistics, the control management mode and the effective control of the energy-saving light source on the hardware have obvious energy-saving effects, especially the energy-saving effect in the early stage can reach more than 7%.
Control technology needs to be promoted in all the energy consumption of modern buildings, lighting accounted for 33, is one of the largest power consumption. On the basis of fully adopting energy-saving artificial light sources, the core of further system energy conservation is to achieve comprehensive regulation and management of artificial energy-saving light sources.
The significance of using lighting energy-saving control system: energy-saving and not saving money is a common phenomenon in the field of lighting energy-saving. The root cause of this phenomenon is the backwardness of technology and the incomprehension of light source. Phenomenon 1: The installation of human body sensing switch and frequent switching energy-saving lamps cause early damage of energy-saving light source, which makes the energy consumption and pollution of energy-saving light source more serious. Phenomenon 2: The timer is used for switching control. In the case of rainy days, it is necessary to manually turn on the illumination of each area, which is inconvenient for the user, and the opening and closing times of the year cannot be automatically adjusted by date. The inconvenience of use and inconvenient management make the promotion of lighting energy saving in the foreseeable future. Phenomenon 3: In the same area, in order to meet the requirements of illumination, the illumination of day and night is the same, resulting in insufficient illumination during the day, and the illumination at night is too high, causing visual fatigue and reducing work efficiency. Phenomenon 4: The office or equipment room has forgotten to turn off the lights. The area will not wait until the next working day to solve the problem of lighting closure in the area. There is no reminder in the middle. To solve these phenomena, an intelligent control system is indispensable. For the first phenomenon, the fluorescent lamp dimming technology of the energy-saving lighting control system not only saves energy, but also prolongs the life of the light source, and completely solves the defects of early damage of the energy-saving light source. For the second phenomenon, the energy-saving lighting control system can accurately calculate the daily sunrise and sunset time of the sun according to the astronomical clock determined by the latitude and longitude coordinates. The illuminance sensor can sense the change of the illuminance like the human eye, automatically adjust the illuminance, and satisfy the illumination of the human eye. demand. For the third phenomenon, the energy-saving lighting control system automatically sets the daylight illumination of the same area according to the spectral sensitivity of the human eye circadian rhythm and the visual efficiency of the bright vision and the dark visual spectrum. For the fourth phenomenon, the energy-saving lighting control system can automatically learn the usage habits of each area, count the usage time of each area, and automatically alarm the unreasonable phenomenon to remind the user to check. Finally, through the energy-saving lighting control system, we get a variety of energy-saving effects. First, through reasonable design, reduce inefficient energy consumption and improve power efficiency. The second is the intelligent lighting system control, which improves the management level. Third, the artificial intelligence is powerful and convenient for users. Fourth, it can be incorporated into the building automation system as a subsystem to reduce the workload of property management. Fifth, through the dynamic control of illumination, time and use state, the service life of the illumination source is greatly extended, thereby prolonging the replacement period of the light source and significantly reducing the running cost of the building.
