Intelligentization has become the mainstream technology of today's building development, ranging from air conditioning systems, fire protection systems to security systems and sophisticated computer networks and communication systems. However, for a long time, intelligent lighting has been neglected in China. Most buildings still use traditional lighting control methods. Some intelligent buildings use building automation (BA) systems to monitor lighting, but only simple area lighting and time switches can be realized. Features. In contrast, intelligent lighting systems show great advantages and are increasingly used in intelligent buildings. The application effect of intelligent lighting system in intelligent buildings is as follows:
î—¥ (1), to achieve intelligent lighting control
î—¥ î—¥ Intelligent lighting control system, the lighting system can work in a fully automatic state, the system will work according to a number of basic conditions set first, these states will automatically switch to each other according to a preset time. For example, when a working day is over, the system will automatically enter the working state at night, automatically and extremely slowly dim the lights in each area, and the system's motion detection function will automatically take effect, automatically turn off the lights in the unmanned area. And adjust the lighting of the area to the most appropriate brightness. In addition, the illuminance of each area can be changed at will by programming to adapt to different scene requirements in various occasions. Intelligent lighting automatically adjusts the illuminance to the most appropriate level of work. For example, in places with good natural light, such as near windows, the system will make good use of natural light lighting to adjust to the most appropriate level. When the weather changes, the system can still automatically adjust the illuminance to the most appropriate level. In short, the system ensures that the indoor illumination is maintained at a predetermined level no matter where it is or how the weather changes. î—¥
î—¥ (2) Improve the working environment and improve work efficiency
In the traditional lighting system, the fluorescent lamp with the traditional ballast flashes at a frequency of 100 Hz. This strobe makes the staff's mind swell and the eyes are tired, which reduces the work efficiency. The dimmable electronic ballast in the intelligent lighting system works at very high frequencies (40~70kHz), not only overcomes the stroboscopic, but also eliminates the instability of brightness during the gliding, providing a healthy and comfortable environment for people. At the same time, it also improves work efficiency.
(3), considerable energy saving effect
î—¥ 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.). When the outdoor light 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 kept at a constant value, so that the natural light can be fully utilized to achieve energy saving. In addition, the intelligent lighting management system adopts the method of setting the lighting working state and realizes energy saving through intelligent management.
(4) Improve management and reduce maintenance costs
The intelligent lighting control system transforms the general lighting artificial opening and closing into intelligent management, which not only enables the building managers to apply their high-quality management awareness to the lighting control system, but also greatly reduces the operation of the building. Maintenance costs and a large return on investment.
