Because the residential quarter is an important place for people's lives, the environment of the residential community will have an important impact on people's quality of life. Most of the residential communities now under construction are beautiful in environment, equipped with facilities and comfortable to live in, which are very popular among urban residents. The outdoor lighting of the residential area can be said to be the crowning touch of the community environment construction, and the role of the community environment, especially the night scene environment, has been paid more and more attention.
The outdoor lighting of the residential area should not only meet the lighting function of the residential area, but also should have the beautiful function, that is, it should be integrated with the landscape design of the community, so that the illuminating and beautiful outdoor lighting at night becomes an important part of the community landscape, and The outdoor lighting of the residential area should also be a green lighting project that is healthy, safe, efficient, energy-saving and environmentally friendly, and establish a suitable, harmonious, humanistic and friendly lighting environment for the community. The main content of the outdoor lighting design of the residential quarters The outdoor lighting design of the residential area mainly includes the landscape lighting and road lighting of the residential community. The landscape lighting landscape lighting of the residential community mainly plays the role of beautifying, setting off and rendering the landscape design effect, and at the same time has some functional lighting.
When selecting the layout of these lighting fixtures, it should be closely coordinated with the landscape designer. Not only the light type itself is required to look good, but also to make the position of the lamp type, the light and the lamp coordinate with the surrounding environment, giving a beautiful feeling. Generally, different lighting methods such as buried lights, garden lights, flood lights, lawn lights, etc. are used to meet the requirements of the community landscape design. Road lighting road lighting in residential areas must meet certain lighting technical requirements, not only to meet the convenience of travel, but also to create a pleasant and pleasant environment for the residential community.
The above two aspects complement each other. Among them, functional lighting is a must for residential outdoor lighting as a public facility, and its basic attributes, while landscape lighting is to further reflect the level of community landscape design, creating a more beautiful and comfortable residential environment. Example of road lighting design in a certain district The road width of a certain district, concrete pavement, several entrances and exits connecting the community are the main traffic routes of the community. The motor vehicles are mainly driven by mini vehicles, as well as non-motor vehicles and pedestrians. Illumination Illumination Determination When selecting the illumination standard of a residential road, the requirements of road users such as motor vehicles, non-motor vehicles and pedestrians should be considered comprehensively, and the surrounding ambient brightness should also be considered.
The road in this district is not far from the residential building. The parking area and the landscape garden are surrounded by high brightness. Therefore, the lighting standard of the residential road should be higher. We take the value of the urban secondary road lighting standard as one. The selection of lighting fixtures also plays a role in beautifying the community environment due to the residential road lighting. Therefore, the district lighting fixtures should take into account the effects of daytime and nighttime. The appearance, scale, lighting of the lamps, brightness of the light source, color table and The color rendering index should be carefully considered.
Therefore, the road lighting of the residential area is based on the combination of decorative and functional. The lamp is made of steel light pole, the tilt angle is the type of lamp head, and the light source efficiency and energy saving requirements are comprehensively considered. The light source is selected from high pressure sodium lamp.
When lighting is arranged, it is necessary to avoid excessive light from entering the windows of the roadside building. In the design, the installation position and height of the lamp should be selected in a targeted manner, the light distribution of the lamp and the illumination angle of the lamp, etc. . The installation height of the street lamp of the residential area is the distance from the side of the road. The road surface is narrow according to the cell road, and the street lamp adopts a single-side arrangement method with good inducibility and low cost, and the spacing is skillful. At the crossroads of the residential roads and the T-junctions, increase the number of street lights to improve the illumination level of the intersections.
Use the method introduced by more than one point. Therefore, when designing the distribution system of public facilities such as community clubs, outdoor lighting circuits should be reserved. In the lighting line with a long distance of power supply, the voltage loss is large, and should be checked. The voltage loss of the lamp at the end of the line should not exceed one. Otherwise, the power supply radius should be reduced. The section of the neutral line of the distribution system shall not be smaller than the section of the conductor of the phase line, and shall meet the requirements of unbalanced current and harmonic current. The road lighting distribution circuit shall be provided with a protection device. When using three-phase power supply, it should be Balance the three-phase power supply. The control circuit for lighting control road lighting should be simple to wire, easy to switch when faulty, and can be manually controlled when the control device is damaged.
The road lighting in this district adopts a combination of photoelectric and fixed clock control. The photoelectric controller is a street lamp main control device, which can control the opening of the street lamp according to the illumination of the outdoor season. The fixed clock can prevent the photoelectric controller from malfunctioning, and strictly guarantees that the street lamp line will not be powered during the day to ensure the personal safety of the maintenance personnel. It can also be used as the main control device when the photoelectric controller is damaged. When the lighting power source is attracted by multiple points, the control line is sent to multiple control boxes to achieve centralized control requirements.
Energy saving of lighting In order to save electricity, reduce line current and reduce voltage loss, this project adopts three-phase four-wire power supply, grounding system, using the buried part of each set of steel rods as the grounding pole, and directly grounding the exposed conductive part of the lamp. . The street lamps of the three-phase power supply are evenly distributed on the line, and two of them are used as the midnight light phase line, and the street lamp arrangement is shown in the figure. Calculation of intersection lighting layout lighting After determining the layout of lamps, light sources and street lamps, use the formula to check the average illuminance of roads. One of the average illuminances is the total luminous flux of the light source, and the utilization factor is determined by the luminaire utilization coefficient curve. A maintenance factor is used. The installation interval of the street lamp is two. The width of the road is related to the arrangement mode. The project meets the design illuminance value requirement.
The power supply for lighting is long due to the long-distance lighting of the residential area, and the landscape lighting location of the residential area is also relatively scattered. Therefore, the outdoor lighting power supply of the residential area should not be introduced from a point. Instead, the street lighting layout should be controlled by a fixed clock, and the clock contact at zero point at night. Disconnect, cut off the street lights on the mid-night phase line to achieve energy-saving purposes, the street light control wiring diagram is shown in the figure. For the convenience of inspection, each street light should be separately provided with fuse protection.
The street lamp is used to lay out the lighting diagram of the wiring diagram. Because the outdoor lighting fixtures and power supply lines are located outdoors, it is greatly affected by the temperature difference of the year and the wind and the sun, and is vulnerable to lightning strikes. The operating environment is relatively harsh.
Therefore, the lighting power supply line usually adopts a laying method along the luminaire arrangement and straightening the cable. The buried depth of the cable should not be less than that, and the steel pipe should be protected across the road.
Conclusion With the advancement of science and technology and the development of social economy, various advanced lighting technologies are widely used in the field of outdoor lighting, especially some new energy-saving and environmentally friendly lighting.
