Talking about lighting energy-saving design
Quasi Ff Gui 5 Feng, talk about the lighting energy-saving design line Honghuai Institute of Technology Architectural Design and Research Institute. Jiangsu Huai'an 223001 can be characterized and based on the above characteristics. Preferred.
China is a country with relatively scarce energy. Energy conservation is a long-term strategic policy for China's economic development. With the promulgation and implementation of the Energy Conservation Law of the People's Republic of China on January 1, 1998, lighting energy conservation, an important part of energy conservation, has become a serious consideration for every electrical designer. According to statistics, China's lighting power is estimated to reach 100 million per year! This is a very impressive number, and it also has huge potential for energy saving.
Since the 1990s, many countries have paid more attention to research and implementation of green lighting projects that save energy and reduce environmental pollution. China has also proposed this plan in recent years, and has exhibited quite broad development prospects. However, due to the imperfect energy-saving technical measures, energy-saving propaganda, energy-saving products have a considerable part of the quality and price factors, the promotion and popularization of lighting energy-saving, is not smooth sailing, and caused a lot of power waste. As an electrical designer, it is reasonable to solve the problem of lighting energy saving from a technical point of view. The way of lighting energy saving is to ensure the use of electrical energy without reducing the quality of lighting. Generally speaking, lighting energy conservation has the following ways to rationally utilize natural light resources, so that it can be integrated with indoor artificial lighting, thereby saving energy.
1.2 According to the national illuminance standard visual operation requirements and the functions of different places, the lighting design illuminance standard can not be reduced arbitrarily, but it should not be improved without any reason. It is necessary to effectively install the power of the unit surface lamp, and preferentially use the partition 1 lighting. Methods and proven energy-saving technologies For rooms where work locations often change, try to use lighting fixtures that are flexible enough to adjust. Such as rail lights, ducted lights, etc.; in places with centralized air conditioning and large lighting capacity, the combination of lighting fixtures and air conditioning return air outlets can be used to comprehensively utilize energy. Market 1 has such products for sale. When choosing, it should be closely coordinated with the air conditioning profession.
1.3 Under the premise of meeting the quality of lighting. For general rooms and places, the high-efficiency gas discharge lamps such as high-pressure sodium lamp metal halide lamps should be used in the high-rise workshops and outdoor venues of fluorescent stadiums. Unless special circumstances, ballast fluorescent high-pressure mercury lamps should not be used. Basement tunnel elevator entrance and exit theater security gates and squatting places, etc., can be considered for lighting with low power consumption efficiency and easy to clean.
1.1 Make full use of natural light This is the lighting control giant Xie Shengzhi 9 several new energy-saving light source electricians should cooperate with the architects, so that the 2.1 thin tube high-efficiency fluorescent lamp can increase the brightness of the ordinary fluorescent lamp by 20 times and the life is up to 80010. The color-based inner-coating phosphor is fully compatible with traditional thick-tube fluorescent lamps, and can be used by designers to replace the new products. It is becoming less and less, and incandescent lamps have been widely used in the countries of Ogo.
3 Several energy-saving technical measures 2.2 Compact fluorescent lamps This kind of lamp was first developed by Fei Lipu in the 1970s. Developed to this day. There are many shapes, such as type, ball and column type, about several varieties. The compact fluorescent lamp has a high luminous efficiency of 50, which is more energy-saving than the ordinary fluorescent lamp 20 than the traditional incandescent lamp 70; the long life is about 5 times that of the incandescent lamp; the color rendering property is good, and the warm color light similar to the incandescent lamp can be made; Easy to use, it can directly replace incandescent lamps. It has been investigated that if the incandescent lamps of the country 15 are replaced by such energy-saving lamps, the annual electricity saving is equivalent to the annual power generation of the Gezhouba Power Plant.
2.3 The mixed light source is a new lighting technology that began to appear in the world in the 1970s. It is to install the above and above + light sources in the same fixture to give play to the advantages of different light sources, thus improving the light efficiency. Improve light color and save energy. K must have a mixed light single lamp and a mixed light double lamp form. Among them, high-pressure sodium lamps and high-light mercury lamps have higher luminous efficiency and more energy-saving. Twilight illumination is more energy-efficient than white light. It is widely used in high-energy space. 2.4 cold reflection single-end illumination halogen tungsten lamp The compact fluorescent lamp 6 was used in the 8th generation to obtain a rapidly developing seed radiation source with a power of 7 guess. It has the advantages of high luminous efficiency, long life, small volume, small decorative and strong color rendering. It is a modern commercial lighting art culture lighting and even family photo 3.1 promotion using low loss. Electronic accessories with excellent performance. Such as electronic ballast electronic trigger. Fluorescent lamps in public buildings such as electronic transformers should be equipped with reactive power compensation devices; compact fluorescent lamps should be selected as electronic ballasts; high-intensity gas discharge lamps should adopt electronic triggers. The estimated 100 million fluorescent lamps used in the country, if equipped with electronic ballasts, only wear this item. The festival is up to 15 B. 3.2 Improve the lighting control method. The use of various power-saving switches is an effective and important energy-saving measure. According to the characteristics of lighting use, it is possible to take control of the lights or appropriate, and add lighting switch points.
Bedroom ward rooms and other bedside locations as well as the ballroom bar restaurant. Consider the high-end power-saving key switch for the higher-level rooms of the dimming switch; the public places and outdoor lighting can be controlled by the program to be photoelectric and devices; the street lamps should be grouped and screwed. Promote the use of night energy-saving control methods.
Aisle stairway awnings and other personnel for a short stay only Changming bulbs with an average of 35 Jia, using ordinary Xiaoban Khan and time switch. The annual power consumption test is 1461.
18.251. The ratio is 8 times worse! The use of timed switches is a priority.
Touch type delay switch sound and light control delay switch Infrared type delay switch is the current kind of timed switch. It compares the following characteristics. Applicable place switch type characteristics Applicable places Main features touch open. Delayed self-touch touch delay switch Disadvantages 1. The person must go to the switch. The light will turn on more than 1 person touch. The switch face is unsanitary. stairs. Attached to fans, etc. Sound and light space delay switch fault sound. Light control is turned on. Delayed self-satisfaction responds to all the loud sounds in nature, so it is wrong to move more than the walkway stair awning and other infrared delays. The main feature is that the person or animal is open at the incident. Delayed self-extinguishing; can be installed in the city of Dengbian City, less price, slightly more expensive, walkway, awning, toilet, etc. The designer should select according to the above characteristics of the time switch and the applicable place, and should pay attention to the following questions: 1 Long corridor When the switch light control is set, the common rocker switch and the time switch can be arranged at intervals, which can ensure the illumination and save energy.
1 Sound and light control delay switch is not recommended for stairwells that are only used during emergency evacuation. The reason is that such stairwells are not passing when normal, and emergency evacuation may be difficult for many years. If the sound and light are extended, the work is off. Most of the switches, the thundering car called the non-human body to turn on the sound of the light, while the contribution is not at the same time, but the life of the switch itself is consumed, it seems that the fire alarm is linked to the emergency lighting, the fire lighting type should be selected. The time switch is the switch when the line is set. When there is a fire alarm, the timing switch is unconditionally turned on by the linkage signal to ignite the emergency light.
6. In addition to the specific case, the priority meter uses an infrared delay switch.
In short, designers should contribute to our modernization in the spirit of practical, safe, economical and energy-saving switches.
