Intelligent lighting systems in intelligent building applications in case the effects - Intelligent

The development of intelligent building has become the mainstream technology, ranging from air conditioning systems, fire systems to improve the security system and computer network and communications systems. But a long time, intelligent lighting in the country have been neglected, most of the buildings still follow the traditional lighting control, part of the intelligent use of a building automation (BA) system to monitor lighting, but only simple area lighting and time switches function. In contrast, intelligent lighting system reflects a strong advantage, it is the application of intelligent building more and more widely. Intelligent Lighting System in Intelligent Buildings effects are as follows:

(1) to achieve control of intelligent lighting. Smart lighting control system, lighting system can work in automatic state, the system will be the first state to set some basic work, the state will pre-set time with each other automatically switch. For example, when a working day, the system will automatically enter the evening's work status, automatically and very slowly dim lights in all regions, while the detection capability of the system will automatically move into force, no one region will automatically turn off lights, Some regions of the light and transferred to the most suitable brightness. In addition, it can be programmed to randomly change the light intensity in all regions to meet the requirements of various situations of different scenarios.

Intelligent lighting can automatically adjust the illumination to the work of the most appropriate level. For example, better lighting near windows and other natural places, the system will make good use natural light, adjusted to the most appropriate level. When the weather changes, the system able to automatically adjust to the most appropriate illumination level. In short, in any place or weather changes, the system can ensure the maintenance of indoor illumination in the pre-set level.

(2) improve the working environment, improve work efficiency. Traditional lighting systems, with a traditional fluorescent lamp ballasts to 100Hz frequency of flashing strobe so that the staff that swollen head, eye fatigue and reduce work efficiency. The intelligent lighting system dimmable electronic ballasts are working in very high frequency (40 ~ 70kHz) not only overcome the strobe, and the elimination of the starter when the brightness of instability for the people to provide healthy, comfortable environment while also improve efficiency.

(3) substantial energy saving. Intelligent lighting control system uses advanced electronic technology, can the majority of lamps (including incandescent, fluorescent, together with the special ballast of sodium, mercury vapor lamps, neon signs, etc.) for intelligent light. When the outside light is strong, the auto-dim interior illumination, outdoor light is weak, the indoor illumination light is automatically adjusted to the indoor illumination remain at near constant value, which can make full use of natural light to achieve energy saving. In addition, intelligent lighting management system is set to light the work of state, etc., to achieve energy saving through intelligent management.

(4) to improve management, reduce maintenance costs. Intelligent lighting control system will be open for general lighting and related artificial converted into intelligent management, managers can not only building awareness of its high-quality management applied to the lighting control system and will significantly reduce the building's operation and maintenance costs and bring greater return on investment.

2 intelligent lighting compared to traditional lighting systems

2.1 Comparison of line system

(1) compare a single control circuit system. One traditional lighting control circuit characteristics: control switch directly connected to the load circuit; When the load is large, for a corresponding control switch capacity increases; When the switch far away from the load, the increased use of large cross-section cable; only to achieve a simple switch function.

Bus intelligent lighting system features a single control circuit: the load circuit connected to the output unit outputs, control switch and the output unit with the EIB bus is connected. Load capacity is large only consider increasing output unit capacity, control switch is not affected; switching distance, the only extended the length of the control bus, saving a large amount of cable cross-section; multiple functions through software settings
