Energy consumption in commercial buildings is expected to drop significantly. The energy regulations of buildings have become more and more stringent, and commercial lighting system integrators have begun to combine the building's original HVAC control network with the lighting system to allow the control center to automatically use the space. Condition and lighting conditions, adjust temperature and brightness to improve energy efficiency. Since the lighting system in the building consumes a lot of energy, the relevant regulations have been revised and the lighting energy loss has to be reduced, which will also affect the design and application of the lighting system. In the past, the energy control of lighting systems was difficult to manage, and the switches had to be manually operated. Although a small amount of space has been automatically controlled by low-cost passive infrared (PIR) sensors, there is still a lot of energy consumption and improved architectural lighting control systems to provide a comfortable environment and good experience. Great effort space. The major countries in the world are demanding a comprehensive reduction in energy consumption, and it is unrealistic to build more power plants that will cost a lot of money. State governments like California, which follow the country's advanced environmental protection, stipulate that in the next 10 years, the goal of significantly reducing energy consumption should be achieved. The California Global Warming Resolution Act (AssemblyBill32) requires buildings to have a 50% reduction in energy consumption by 2018. Other building regulations such as the CaliforniasTitle24 further stipulate energy savings from daylight harvesting and automatic lighting controls for windows and skylights. Of course, the United States is not the only government that wants to improve energy efficiency in commercial lighting. The EU is currently discussing a plan to phase out ineffective light bulbs and develop commercial lighting regulations that require time to control automation. A new generation of LED lighting systems came into being. First, a brief look at where energy is used: in a traditional commercial building's electricity bill, lighting costs account for 40; among all the lighting energy used, commercial lighting accounts for nearly 70. Other energy sources, including HVAC systems, account for 40% of energy used in commercial buildings, and other energy sources such as electric motors consume 20%. The HVAC system was adopted by the building network control in the 1980s, and the patented FieldBus network such as ProfiBus evolved into the standard network that BacNet uses to connect to HVAC systems. BACnet is an ASHRAE, ANSI and ISO standard agreement for building automation and network management. It not only allows system automation, but also heating, ventilation, air conditioning control, lighting control, access control, fire detection systems, and other application-related control systems. It is only natural that lighting and HVAC systems are centrally controlled by the network. What systems can control lighting better than existing building control networks? Today's lighting systems are developed from pulse-width-modulated (PWM), single-junction field-effect transistors (FETs), resistors, capacitors, sensors, and other difficult-to-control discrete power components, so as in the past, various technological revolutions, lighting The system also needs to be reformed to enter a new era of digitalization. Connecting and integrating power electronics with a network that controls lighting will dramatically reduce energy consumption for next-generation lighting systems such as light-emitting diodes (LEDs). HVAC/lighting management is more intelligent with the building control network. If the brightness of the lighting system is adjusted from 0 to 100, it can also be connected to the control network of the building, which can not only meet the needs of use, but also develop into a building autonomous control system. (figure 2). In addition, smart sensors that can detect space usage and lighting conditions can also raise public awareness of environmental protection. The building's usage information is transmitted to the central control via the network, and the lighting controller can receive the message. As a result, the central control office can automatically manage the lighting and HVAC system based on time and space usage. These networked lighting systems powered by smart sensors can save a lot of energy. Suppose there is an underground parking lot where the lights are fully illuminated 24 hours a day, and when no motion is detected, the lights are automatically dimmed, saving more than 50 energy. The system can also be integrated with adjacent sensors to help detect parking spaces and inform driving where to park, shortening the process of finding empty spaces, reducing gas consumption and carbon footprint. Other major applications include street lights and outdoor parking lots. In both environments, the lighting is fully illuminated from dusk to early morning, with or without vehicles or pedestrians. The streetlights driven by the sensors can reduce the brightness by 50 after two in the morning, and the sensors are connected to each other. The coverage range covered is long. If the detection arrives at the vehicle, the street lights will be automatically turned to full light. Other environments, such as offices and high-rise buildings, are usually fully lit even if no one uses the lighting system. Therefore, it can be set to darken the lights in these places when "no motion is detected" or "after 8pm". shut down. Adopting an Automated Energy Saving Strategy Commercial Lighting Efficiency Enhancing Commercial Lighting focuses on efficiency while also requiring a new digital architecture to provide new features and reduce costs. Autonomous controls and sensors reduce maintenance costs and significant energy savings, saving ample resources to help replace obsolete traditional lighting systems. LED lighting has a lifetime of 30,000 to 50,000 hours, compared to 10,000 to 25,000 hours for fluorescent lamps and 5,000 to 11,000 hours for halogen/incandescent lamps. . Fluorescent lamps have a slight flicker at the AC (AC) line frequency, and its spectrum is limited to present all colors, so some people don't like to use fluorescent lights. Although today's fluorescent lamps operate efficiently, they can become very expensive when added with adjustable low-brightness components. In addition, the fluorescent lamp stabilization system cannot shorten the on/off loop time, and the motion sensor or proximity The ProximityControl solution is not ideal. When LED lighting is properly designed, it can achieve up to 30,000 to 50,000 hours of life, better spectrum, no flicker, and faster brightness adjustment. An automatic energy-saving strategy in a commercial lighting environment that examines space usage and proximity detection, and detects when people in the room are leaving, control time, and ambient light sensing adaptation. The detected information can be controlled in a variety of ways: The dimming lighting controller uses standard feedback loops and control mechanisms to reduce the lighting output of the fixture when not needed to avoid wasting energy. Works best with LED lighting. Optional light conversion in large rooms, with fixed steps such as turning on the second or third source to enhance the illumination output or reduce the brightness. Autonomous lighting controls low-energy wireless networks such as ZigBee, Wi-Fi, or wired networks such as DALI, DMX, which can provide specific lighting solutions for individual locations, as well as central control based on policies and requirements. System to control lighting. Improving Energy Management Building-Connected Lighting Systems Designers of commercial luminaires and lighting systems are facing new challenges. In addition to new government-defined specifications, customers are beginning to become interested in high-performance green products. Building-connected lighting can be applied to HVAC energy management and lighting management, making total energy management within the enterprise easier. Building-connected lighting systems allow companies to control the overall temperature and lighting required for each room, and automatically review the space and time they have taken to improve overall energy management.
