The application of intelligent lighting control system in architectural lighting The lighting in Xu Modern Architecture of Nanjing Transportation Vocational and Technical College of Jiangsu Province not only requires good visual conditions for people's work, study and life, but also can be used to create a harmonious use of luminaire modeling and light color. An indoor environment with a certain style and aesthetics to meet people's psychological and physiological requirements.
1 In the public area, the intelligent lighting control system is adopted. 1.1 Public areas such as elevators, garages, bicycle garages, etc. Intelligent lighting control systems are used for elevators, garages, bicycle garages and other areas with high frequency of lighting, which can ensure the most suitable lighting for residents. At the same time, achieve reasonable energy saving.
At night, the “floor manager†selects the “safe†state. At this time, the lighting system usually only lights the ordinary low-energy lamp, which is used to ensure the basic illumination required for emergency or security inspection, thus achieving reasonable energy saving and reduction. The purpose of operating and maintenance costs.
1.2 Property management office area and residential equipment area In the equipment area of ​​the house, such as elevator machine room, pump house, underground power distribution room, etc., the lights are usually closed, and only when the management personnel enters, the static and dynamic detectors will automatically The light is on. When the person in the room enters, the static and dynamic detector will automatically light up the light. When the person in the room finishes walking, the detector will automatically turn off the light after a delay.
Property Management The office lighting system differs from the traditional BAS energy management system in that the intelligent lighting management system allows the staff to change the working state of the lighting system at any time to suit the task at hand. Photocells and motion detectors constantly monitor the illuminance and motion of the area, and use this information to make adjustments or select more appropriate conditions, thus providing managers with a comfortable working environment while avoiding unnecessary energy waste. For each pre-set light sensor, whether it responds to high illumination or low illumination or responds to static and dynamic sensors, it can be set remotely using hand or PC.
2 The effect that intelligent lighting control system can achieve 2.1 Realize the intelligent control of lighting After adopting the intelligent lighting control system, the lighting system can work in the automatic state, and the system will work in several basic states that the illuminance is automatically adjusted. These states automatically switch to each other at a preset time and automatically adjust the illuminance to the most appropriate level for the job. In places with natural light, such as near windows, the system will make good use of natural light lighting to adjust to the most appropriate level. In addition, you can manually change the illuminance of each area by manually programming the control panel and remote programmer to adapt to different scene requirements in various occasions.
2.2 Consistency of illuminance When lighting designers design new buildings, they will consider that the luminaires will be decayed over time, efficiency and room wall reflections. Therefore, the initial illuminance is set higher. This design not only causes inconsistencies in the illumination period of the building (or the interval between the two decorations), but also causes unnecessary energy waste due to the high illumination. After the intelligent lighting control, although the illumination is still high, but because of the intelligent dimming, the system will maintain a constant illumination of the illumination area according to the preset standard brightness, without being reduced by the efficiency of the lamp and the attenuation of the wall reflectivity. influences.
2.3 Scene Transformation Flexibility The intelligent lighting control system can preset different scenes in the module. When necessary, the corresponding control panel can be adjusted to the corresponding scene. The user can also adjust the scene in time through the programmable control panel to adapt to different scene requirements. In addition, the user can also use the portable programmer to perform transformation settings for different scenes through the programmable interface.
2.4 Considerable energy-saving effect The intelligent lighting control system uses advanced power electronics technology to intelligently dim most lamps (including incandescent lamps, fluorescent lamps, sodium lamps with special ballasts, mercury lamps, neon lights, etc.) Make full use of nature to achieve energy saving. The photoelectric unit is installed in an area that utilizes natural light. When the outdoor light intensity is strong, the indoor illumination is automatically dimmed, and when the outdoor light is weak, the indoor illumination is automatically brightened, so that the indoor illumination is always maintained at a constant value, and at the same time, considerable energy saving is achieved. effect.
2.5 Extending the life of the light source It is well known that the main cause of damage to the light source is the overvoltage of the power grid. As long as the working voltage is properly reduced, the life of the light source can be prolonged. The intelligent lighting control system adopts the soft start method, which can control the surge voltage and surge voltage of the power grid to protect the filament from thermal shock, thereby prolonging the life of the light source, and has special significance for a large number of light sources and difficult installation areas.
3 Intelligent lighting control system economic analysis After adopting intelligent lighting control system, the owner's one-time input cost will greatly reduce the actual input cost due to the reduction of operating costs and maintenance costs. Let's take an office building with an area of ​​about 1000 square meters as an example to estimate the economics of the regional intelligent lighting control system.
3.1 System basic situation Luminaire 1! 0 sets of 2x36W fluorescent lamps, total power 9.6kW, the number of loops is 1! The working time is 10 hours/day, 300 days per year, and the electricity fee is 0.5 yuan/kWh.
3.2 Intelligent system investment return estimation The basic configuration price of the intelligent system is 41,000 yuan. The cost of the conventional grid control device for the original lighting system is 5,000 yuan. The cost of using the intelligent system is 36,000 yuan. The system annual operating electricity fee; 10 hours/day x 300 days x 0.5 Yuan / kWh x9.6 kW = 14400 yuan, the annual savings of electricity costs according to the savings of 50 to 7! 00 yuan (expanding the life of the light source to 3 times), if not using the intelligent system, change once a year, need 1680 yuan, using After the intelligent system, it will be changed once every 3 years, and the annual lamp saving cost is 11!0 yuan. Reduce the cost of use in the year:! 00 yuan c 11! 0 yuan = 83! 0 yuan intelligent control system recycling period; increase costs / year to reduce operating costs "4 years.
4 Conclusion Intelligent lighting can not only improve the quality of the building, but also match the lighting system with other intelligent equipment in the building. It can also improve the working environment, improve work efficiency, save energy, save lamps, reduce operating costs, and thus obtain huge economy. Return. (column editor / Luo Bin)
