(Anhui Institute of Architectural Science and Research, Hefei 230001, China) This paper mainly introduces several forms of outdoor night lighting design in residential quarters, and puts forward some views on the selection and control of lamps. Residential quarters; night lighting; microcomputer time-controlled switches With the rapid development of the national economy, people's requirements for their living environment are also increasing. The outdoor lighting design in the residential area should be comprehensively designed in combination with buildings, terrain environment, and people flow. When designing the night scene, full consideration should be given to the visibility, orientation, safety, dynamic landscape and environmental atmosphere of the lighting. Outdoor lighting in the small area is common in the following types: central landscape (square) lighting; main and branch road lighting; fountain and water lighting lawn and sculpture lighting. All types of lighting fixtures should be reasonably distributed in conjunction with the location of the building. The central landscape square lighting center landscape (square) is the center of personnel activities in the community, and is also the focus of lighting design. The illumination needs to reach 200LX~350LX to ensure that the illumination at this night is significantly higher than the surrounding buildings. Playfulness can also beautified with colored lights. High-color floodlighting is used to highlight the shape and color of the local structure. The lighting design should harmonize the shape, brightness and color of the fixture with the surrounding environment. In the choice of lamps, it should be beautiful, vivid, and try to avoid glare. Taking into account the relatively concentrated personnel, the grounding and leakage protection of the lamps should be taken seriously. In the current situation that green lighting has been increasingly valued by countries all over the world, it is also necessary to tap the energy saving potential from lighting design, lighting products, lighting management, natural light utilization, etc., pay attention to the use of new lighting technology, raise the content of high technology, save energy and save energy. Protect the environment and prevent light pollution as much as possible. High-altitude lights and garden lights are used for road lighting in small areas. The height of the street lights on the main road should be determined according to the arrangement of the street lights, the effective width of the road, the light distribution of the lamps and the power of the light source. The distance between the luminaires is related to the luminaire and the installation height. The installation height is high and the spacing can be large. The distance between the high pole lights is generally around 30, and the lamps are mostly arranged along the periphery of the cell. The light source is usually warm light. The courtyard lights are mostly distributed on the branches and buildings on both sides of the community. The height can be selected according to the single-lane lamp 0.6B and the double-lane lamp 1.2B (B is the road width). The distance between the light poles of the garden lights is generally about 20, and the light source is mostly made of energy-saving lamps. In the design of street lighting for residential roads, the lighting points should be arranged reasonably in combination with each scenic spot and path to achieve good lighting and guiding effects. The selection of lamps should be combined with the atmosphere of the whole community, and the outdoor garden lamps with coordination, beauty and comfort can be used to outline and beautify the community landscape from space and plane. At the same time, pedestrians also have a good sense of security in the night. At present, some high-end sub-districts have set up large water features and some fountains in the community, creating a very beautiful living environment. Usually, there are facilities such as a fountain full of dynamics and water drop, and the water features are static and mobile. In the lighting design scheme, the static water surface and the pond can be immersed in underwater floodlights to illuminate the flow waterfall. The luminaires can be installed at the bottom of the water drop, while the step water curtain has a slower water flow and a lower drop. Small, tubular lamps can be set in front of each step. The local landscape is more lively by changing the color of the light. The direction of the light emitted by the lamps can be horizontal or vertical. The general illumination can be selected with incandescent lamps. Adjustable, color lighting can also be used to make the water scene full of vitality. In order to make the shape of the water spray constantly change, the background music and water pump system can be combined to form a 'sound-controlled fountain' when there are conditions. The fountain lighting fixture is generally installed below the water surface 30rM00ri, the end The illuminance is about 150LX. The illuminance at the end of the water spray can be selected according to the light and dark conditions around the fountain. The environmental characteristics of the water spray end illuminance value (LX) The light and dark fountains have submersible pumps, solenoid valves, underwater lights, etc. The possibility of contact is great to ensure personal safety, and the submersible pump should be protected by an earth leakage circuit breaker. 220V/380V/36V isolation transformer is required for underwater lighting. The lawn lights in the residential area can be used to embellish the landscape environment, and the spacing can generally be 3.5! ~5.0! (! is pole high). The lighting features are a large number of lamps, a wide distribution range, a relatively small single lamp power, a low natural power factor, a long power supply line, and a large current superimposed on the neutral line. It is advisable to adopt sub-item and group control for the opening of the luminaire. The principle is that the group with the primary and secondary functions is switched separately considering the time period and the season. Also due to the long line and single lamp power, the line section is selected to ensure that the voltage is reduced to 5%. Sculptures, gazebos or large trees in the small area can be illuminated by local floodlights. Designers should fully understand the overall concept of the owner and landscape architect when designing the outdoor lighting of the residential community, and conduct on-the-spot investigations to determine the main and secondary landscape observation viewpoints, determine the overall thinking and the content of the key performance, and determine the illumination. Choose the appropriate power supply or control method for the level, lighting method, light source and number of lamps, lighting equipment and materials. The control of various lighting fixtures in the small area should be set by manual and time control. The street lamp time control mainly adopts photoelectric control and time type switch control. Photoelectric control of light control energy saving effect is better, but the stability is poor, there is the possibility of misoperation, because the photoresistor is greatly affected by the weather, so the control time error is also large, and the failure rate is high, the maintenance workload is also Correspondingly larger. Time-type switch control is gradually being widely used with the expansion of the field of computer use. At present, some microcomputer-based time-controlled switches for road lighting, landscape lighting, etc., which need to be turned on and off regularly, have been developed in China. It has the characteristics of no power failure (internal automatic charging), small size, convenient debugging and flexible control modes. In summary, with the development of society and the improvement of material living standards, people's requirements for their living environment are gradually improved. The outdoor lighting in the community is a kind of lighting art that uses lights to shape the night image of the community. In the design process, it should be adapted to local conditions, scientific planning, and careful design to achieve good visual effects.
