According to different working conditions, intelligent lighting control system can be divided into single-phase and three-phase two types .

Species distribution

1. Intelligent lighting control system with one grid and two lines.

It can set or change individual control, group control, scene mode control and time control at any time on the host computer of the system without complicated programming.

Main Effect Editor

1. Automatic lighting control

The most important feature of the system is scene control. There are multiple lighting circuits in the same room. It is called scene after adjusting the brightness of each circuit to achieve a certain lighting atmosphere. It can set different scenes in advance and change the fade-in and fade-out time of the scene to make the light soft and changeable. Clock control, the use of clock controllers, so that the light presents a daily sunrise, sunset or time-dependent changes. Using various sensors and remote controllers to achieve automatic control of lighting.

2. Beautifying the Environment

Indoor lighting uses scene changes to increase the artistic effect of the environment, create a sense of three-dimensional and hierarchical, create a comfortable environment, which is conducive to people's physical and mental health and improve work efficiency.

3. Extend lamp life

The main factors affecting the lamp life are overvoltage and cold shock, which greatly reduce the lamp life. The LT series intelligent dimmer has the output voltage limiting protection function: when the grid voltage exceeds the rated voltage 220V, the dimmer automatically adjusts the output to within 220V. When the bulb is connected in cold state, it will produce 5-10 times of the rated current, which greatly affects the lamp life. Intelligent dimming control system adopts slow-opening and fade-in and fade-out dimming control, which can avoid cold impact on lamps and prolong lamp life. The system can prolong the lamp life by 2-4 times, save a lot of bulbs and reduce the workload of replacing bulbs.

4. Energy conservation

The brightness sensor is used to automatically adjust the intensity of the light to achieve energy-saving effect. Using mobile sensors, when people enter the sensor sensing area, the light gradually rises, and when people leave the sensing area, the light gradually decreases or extinguishes, so that some corridors and corridors can be controlled, so as to achieve the purpose of energy saving. For example, in order to save electricity, a hotel replaced all corridor lights with 5W energy-saving lamps to reduce energy consumption, but the problem is that the comfort of energy-saving lights is very poor, the illumination is reduced, and the hotel grade is reduced. Mobile sensor control is recommended.

5. Consistency of illumination and illumination

Using illumination sensor, indoor light can be kept constant.

For example, in the school classroom, the intensity of light near the window and the wall is the same. Sensors can be installed at the window and the wall respectively. When the outdoor light is strong, the system will automatically reduce or close the light near the window and adjust the brightness of the light near the wall according to the wall sensor. When the outdoor light becomes weak, the sensor will adjust the brightness of the light to the pre-set illumination according to the induction signal. Value. The luminous efficiency of new lamps and lanterns decreases gradually with the use of time, and the reflectivity of new office buildings decreases with the use of time. Thus, the inconsistency of illumination between the old and the new will occur. The illumination can be adjusted to achieve relative stability through the control of intelligent dimmer system, and energy can be saved.

6. Integrated Control

The whole system can be monitored by computer network, such as understanding the working status of current lighting circuits, setting and modifying scenes, and controlling the whole system and issuing failure reports in case of emergencies. LT-net intelligent lighting control system can be connected with BA system or fire fighting system, security system and other control systems of buildings through gateway interface and serial interface. It is usually composed of dimming module, switching power module, scene control panel, sensor and programmer, programming interface, PC monitor and so on. The above-mentioned modules with independent control functions are connected to a computer. On the data line, an independent lighting control system can be formed to realize various intelligent management and automatic control of the lighting system.

General characteristics

1. The system can control continuous dimming or switch in any circuit.

2. Scenario control: multiple different scenarios can be set up in advance, fading in and out during scene switching. 3. All kinds of sensors can be connected to automatically control the lighting.

4. Mobile sensors: infrared detection of human body to achieve the control of light; if people come to light, people go out of the light (dark).

5. Light illumination sensor: For some occasions, indoor light can be adjusted according to the intensity of outdoor light, such as constant illumination control in school classrooms.

6. Time control: In some cases, the brightness can be adjusted with the time of commuting.

7. Infrared remote control: The light can be controlled by hand-held infrared remote controller.

8. Systems networking: Systems networking, using the above control means for integrated control or networking with building intelligent control systems.

9. Lighting control can be achieved by moving detection of sound, light, heat, human and animals .

Connotation demand

connotation

Voltage varies from place to place in China, so the design voltage of various lamps is generally lower than the standard phase voltage 220V in order to satisfy their normal start-up and luminescence under different conditions. In order to facilitate power transmission, power system often increases the transmission voltage, resulting in higher actual working voltage of lighting lamps. These excess voltages not only can not make the lamps work more efficiently, but also have two negative effects: wasting energy and shortening the lamp life.

In view of the fatal defect of the existing lighting circuit, Dr. Baowa DL series intelligent lighting energy-saving control system optimizes the input voltage of the power supply system by electromagnetic induction. AC-AC direct conversion technology is used to adjust the voltage. The voltage transmitted to the lighting load is the optimum value of the design voltage of the lamps. This not only saves electricity, but also prolongs the life of the lamps. It also guarantees the triple purposes required by lighting standards.

According to the basic electrical principle P=U2/R, the voltage applied on the lamp is U, and the impedance of the lamp is R. Then the power consumed under the original voltage U0 is P 0. When the voltage is appropriately reduced to U1, the power consumed will decrease with the square relation of the voltage. Its active power saving rate is expressed as follows: e%= 1-(U1/U0) 2 x 100%.

As far as fluorescent lamp tubes are concerned, only sufficient rated voltage is required to excite fluorescent substances to make them luminous at start-up. In the preset time, the intelligent lighting control system senses that the power of the lamp has been fully exerted, that is, automatically adjusting the load voltage, the lamp can be transferred to the power-saving mode, and the intelligent lighting power-saving control system also enters the automatic online detection state. According to a large number of experimental results, the illumination of fluorescent lamp decreases by only 7% when the power supply voltage decreases by 10%, while the human eye's perception of light is logarithmic: that is, when the illumination decreases by 10%, the human visual perception brightness decreases by only 1%. Therefore, the human eye can hardly feel the slight change of illumination caused by reasonably reducing the input power of lamps, and the intelligent lighting control system is prolonging the lamp life. Both life and maintenance cost are of positive significance. demand

1. Humanized and Intelligent Management

This requires better user experience and integration of software and hardware. In hardware, ZigBee wireless technology, combined with GPRS (or 3G/4G) technology, can achieve close ZigBee operation, long-distance GPRS control, far-near combination of communication methods, can be thousands of miles away, still within a short distance. In software, it is highly integrated with scalable functions, basic requirements (lamps and switches), expanded requirements (current, voltage, power factor detection), innovative requirements, and flexible composition. It not only meets the lighting needs, but also expands more functions to bring better user experience.

2. Energy saving and environmental protection

Intelligent lighting control system must conform to the current concept of energy saving and environmental protection, because lighting has always been a major consumer of urban power consumption, if the premise of ensuring lighting demand to achieve energy saving and environmental protection, it is a problem that must be solved. The emergence of intelligent lighting control system solves this problem. More cities use energy-saving lamps to replace, hoping to solve this problem, but with the large-scale expansion of the city, more and more lamps and lanterns can not be fundamentally solved, but the use of intelligent control system can solve this problem, in order to achieve secondary energy-saving LED lamps, LED is to support the function of adjustable light, intelligent lighting control system can be in accordance with the time period of lamps and lanterns. Or adjust light and control according to demand, and can realize single lamp control and multi-lamp control of lamps and lanterns, further save energy. And because LED belongs to environmental protection products, it can ensure that the environment is not polluted. Through data comparison, the use of intelligent lighting control system can save electricity on a large scale.
