Lighting technology talk about lighting control Shanghai Mechanical and Electrical Design Institute Liu Guangliang buildings are inseparable from lighting, but also inseparable from lighting control. In actual use, due to different use places and different requirements, different effects are required, and lighting control is required. The so-called lighting control is to use a set of components to control the device, control the lighting system to meet people's use requirements, create a different atmosphere, and produce satisfactory results. The correct lighting control method is an effective means to achieve comfortable lighting, and is also an effective measure for energy saving. Lighting Control 1. Manual control uses components such as switches to control the on and off of the illuminator with the simplest manual operation. The utility model has the advantages of simple structure, convenient operation and low cost, and the illuminator is only turned on when needed, saving energy and eliminating waste. It is the most commonly used control method in engineering design, and is suitable for general civil buildings and industrial plants. It includes the control method of the seesaw switch control. Can be divided into manual control, automatic control and intelligent control. In the lighting engineering design, we must select the reasonable lighting control body 25688m and stamping 24925m2 large workshop lighting design manual control according to different building type requirements. The main circuit and control principle, because the intersection 21 back to the Weizhou circuit, plus 0 road 迢枧 明 明 Because the workshop area is large, the design first divides the workshop into several areas according to the process flow, and then according to the setting system of each area, the control button is set at Main passages and entrances to the workshop. Considering that the lighting source in the workshop is metal halogenated several lighting distribution boxes. The whole workshop lighting is divided into general lighting and patrol lighting. Considering the night duty patrol, the lighting control adopts the centralized lighting control, and the control buttons are set on the corresponding distribution box panel. The patrol illumination decentralized control light has a stable time of 4 after startup and a restart time of (3) in order to prevent the continuous operation and continuous shutdown of the misoperation, affecting the life of the lamp, and adding a power-off delay function in the control loop. In the main circuit, each outlet circuit is equipped with a single-pole circuit breaker to prevent a loop failure from affecting the normal operation of other circuits. At the same time, it can control the continuity of the circuit according to the changes in the use requirements, and save energy. 2. The automatic control system is based on manual control, making full use of photoelectric sound and other technologies to control the lighting system. It transmits the optical signal acoustic signal through the sensor, is amplified by the amplifier, and is converted into an electrical signal after filtering. The guinea triggers the conduction to achieve the purpose of voltage regulation, thereby controlling the loop current and adjusting the light output of the illuminator. It can be controlled in a wide range and can be controlled in a small range. It is flexible in use; it not only controls the on-off, but also continuously dims, and the control is more effective scientific and accurate. It is the control method commonly used in office buildings today. The control method includes timing control through an 8-person 5 interface, optical loop electrical induction control, and the like. Control system details 3. With the continuous development of science and technology, lighting control technology has entered a new stage of intelligence. That is to say, mainly based on computer and network technology, using microprocessor technology and storage technology, the information from the sensors and sensitive components on the lighting condition of the building is processed, and the devices in the lighting circuit are controlled by predetermined program instructions. By programming different control procedures, different lighting levels can be provided to create a different atmosphere. The intelligent lighting control system is an all-digital block-distributed distributed control system. The whole system consists of various modules such as the management module dimming module detection module operation module. Each module contains a microprocessor memory or just a memory, and each function of the system is stored in a module. The system network connection only needs ordinary telephone line or unshielded twisted wire. 1. In addition, it acts as a subsystem of the intelligent building automatic control system, and through the computer network, not only can the lights of various areas be controlled at the scene, but also The central monitoring system monitors the lighting conditions and connects with other control systems to achieve building management. The following is an example of a 08-bar bus lighting control system for the lighting design of a large-scale automobile factory's quality control center using the Australian 13-inch Qisheng Company. The lighting system participates in the steel structure, the glass curtain wall of the main entrance lobby, and the office integrated floor of the inner layered concrete structure is a functional area for the open living and office and inspection center. Due to the large area of ​​each area and the uncertain internal layout, it is considered to divide the illumination into several areas in the design, and each area is divided into several loops. This way, the lighting circuit can be adapted to the requirements no matter how the layout changes. Lighting control is adopted, and the output components of the 3 fat bus lighting control system control each circuit. For a large area, the relay module circuit output control circuit contactor realizes lighting control. For small office inspection rooms, etc., the relay modules are directly controlled in the main circuit, but each output capacity of 750 inductive loads must be guaranteed. The dimmer module mainly provides the ceiling fan speed control and the individual process detection room module in the rest locker room. The entire building is only equipped with a panel switch input button at each major entrance and exit, a small office inspection room, a rest locker room, etc., and all lighting is controlled by software programming. The system output component relay module dimmer module power supply unit and other distributed installations are installed in the lighting distribution box of each area, which reduces the length of the strong electric cable and facilitates maintenance. If you rely on Zhou Ming 2 by Zhou Ming asked 3 large office lighting large office lighting, lobby lighting 7 by the curtain wall lighting, 8 by the curtain lighting 10 12 small office lighting detection lighting, changing clothes, 1 fan, the layout changed again When you do not need to modify the line, you only have to reprogram. The entire quality control center lighting is automatically controlled by the central monitoring computer. It is controlled by the timing program. It automatically lights up during working hours and automatically turns off the lights after work. When some areas need lighting, the corresponding circuit may be opened by the panel switch input button on the site. In the vicinity of the glass curtain wall and the window, an infrared brightness sensor is set to collect the field illumination, and the information is transmitted to the relay module, and the relay module automatically controls the switches of some circuits to achieve the purpose of energy saving. In short, with the continuous development and improvement of lighting control technology, we will get a more comfortable lighting environment and lighting space, and achieve better economic and social benefits.
