Discussion on energy saving application of rocker

Abstract: This paper briefly introduces the classification and control methods of indoor lighting control in civil buildings, and focuses on some energy-saving and humanized design schemes using traditional wall rocker switches in lighting control. One is the summary of the author's study, and the other can be used as a reference for colleagues with a view to attracting jade

key words: green lighting, people-oriented, energy saving lighting control

at present, saving requires choosing and designing different fixtures according to different experimental forces and the shape and size of samples Energy has become a top priority. In modern buildings, due to the continuous improvement of people's living standards, lighting energy consumption has accounted for a considerable proportion. At present, the concept of "green lighting" vigorously advocated is actually advocating energy conservation, pollution reduction, environmental protection, and improving the quality of work and life in lighting projects. The urgent requirement for energy conservation is that the quality is (200 ± 20) g and the bottom end is cut into a square device with a side length of (25.5 ± 0.1) mm, which makes lighting control more and more important. This requires that practitioners should not simply repeat previous experience in lighting design and creation, but should vigorously carry out investigation and research, constantly update technical knowledge, push through the old and bring forth the new, and explore and use better lighting control methods, Make a contribution to the construction of an economical and harmonious society

lighting control can be divided into two basic categories: Static Control (also known as on-off control or switch control) and dynamic control (also known as dimming control) of ACR foaming processing aids 5.0~8.0. Switch control uses wall rocker switches, circuit breakers, relays (Contactors), solid-state switches (thyristors, etc.), timers, sensors (including photoelectric sensors, human body sensors, sound sensors, infrared sensors, etc.) to control lighting; Dimming control is the use of dimming devices for lighting control. Dimming control can save energy, improve work efficiency, enhance flexibility, and play a good aesthetic effect. Lighting control can be divided into manual and automatic. Manual control is the use of switches or dimmers or by switches and dimmers to achieve the control of lighting; The automatic control system is composed of clock elements, photoelectric elements, human body sensors and other components or computers, or they work together to realize the automatic control of lighting

lighting design should be people-oriented, on the premise of creating a good visual environment, according to the different characteristics of different building types, and from the perspective of ergonomics, to achieve the purposes of convenient use, improving work efficiency, benefiting activity safety and visual health, and saving energy consumption. The user of lighting is human, so great efforts must be made to study the behavior of "people using lights" when formulating lighting control strategies and determining lighting control systems. The setting of switches shall be based on the basic principle of facilitating management and energy saving

next, the author focuses on the energy-saving and humanized design of the wall rocker switch, which is the most widely used in civil buildings, in lighting control. First of all, the number of lamps controlled by each rocker switch should not be more than 4 (its purpose is to reduce the index of electric energy consumption). In terms of control mode, zoning and grouping without lamp separation can be adopted Separate single lamp control and separate double lamp control, etc. (separate lamp control can easily achieve the purpose of "constant brightness" and energy saving in different scenes. Compared with advanced intelligent lighting control, it hardly increases the investment cost, and there is no problem that the construction unit accepts it or not); Two place single connection control and two place double connection control; Three ground single connection control, three ground double connection control, etc. Double control switch and intermediate switch (also known as intermediate switch) are very good products. The author highly recommends that they are widely used in civil buildings. It is easy to control lamps in two places by using single (double) double control switch, and it is not difficult to control lamps in three or even four places by adding intermediate switch. In public buildings (or when measuring electricity bills in public), if people can easily turn on/off the lights everywhere without running around for turning on the lights (especially turning off the lights), they will turn off the lights after using them (in general, few people will turn off the lights after taking a few more steps, just like turning off their own lights). Since people can turn off the lights easily on the premise that designers have done a good job in the design of lighting control, the lighting energy consumption will be reduced accordingly. In the long run, the energy-saving effect is considerable

the following are several schemes of using wall switch to control lights that the author often uses in lighting design and creation, which are summarized and sorted out for reference

I. common two place lighting scheme: the principle is shown in the attached figure (I), which is the simplest and most commonly used two place lighting scheme

II. Common three ground control lamp scheme: figure (II) shows the legend of Midway switch and its equivalent circuit diagram, and figure (III) shows the common three ground control lamp scheme, which uses two single Gang double control switches and one midway switch to realize the control of the same (Group) lamp from three places. No matter which of the three switches acts, it can cause the light on/off change

III. common four ground control lamp scheme: the lamp control principle is shown in the attached figure (IV). When the switch at any place of ground a, B, C or D can control the light on and off (this lamp control scheme is used in few occasions)

IV. the downward rotation scheme of the jacking hook and swing mechanism of the multi ground group control lamp: as shown in the attached figure (V), the multi ground group control of lamps is realized by using the double control switch and the double midway switch. When one of the double half-way switches of ground B or ground C is removed, the attached figure (5) becomes the three ground grouped lighting scheme; If the double half-way switches of ground B and ground C are removed, the attached figure (V) changes to the two-way grouped lighting scheme. The two place or three place grouped lighting control scheme is especially suitable for the lighting control of some building corridors and some multi door rooms (empty rooms). It is not only convenient to use, but also can play a good role in saving energy consumption

v. lighting control scheme of emergency lighting: there are many types of emergency lights, such as continuous type (also known as normal ignition type), non continuous type (also known as normal non ignition type) and normal emergency dual-use type. The author himself advocates the normal emergency dual-use type (usually, the ignited type wastes not only electric energy but also the life of the lamp because the lamp is always on; usually, the non ignited type may "strike" at the critical moment because of its lack of "care" when it is needed because it is always "useless for heroes"), Normal emergency dual-use type can be divided into single lamp with battery type and centralized power supply type (using ordinary lamps). The following mainly discusses the use of EPS as a single lamp controllable lamp control scheme in the centralized power supply emergency power supply:
