Only by fully considering the particularity of the bridge lighting, combined with the general decorative lighting and road lighting methods and principles, it is possible to carry out a reasonable, safe and comfortable lighting design for the bridge. So, how does bridge lighting reflect the idea of green lighting? 1. Pay attention to lighting quality, seriously consider the light sources and lamps of functional lighting and decorative lighting. When installing, prevent the brightness and light color of decorative lighting from interfering with the vision of motor vehicle drivers, strictly control glare, and reduce light pollution to ensure vehicle dealers. smooth and reduce the traffic accident rate. 2. High-efficiency lighting equipment and high-efficiency light sources are the important basis for lighting energy saving. In the design, lamps and equipment with high protection level, advanced and good energy-saving characteristics should be fully used, lighting products with the best light distribution curve should be selected, and high-efficiency light sources (luminous efficiency, color rendering, life, etc.). 3. Adopting advanced lighting control methods, under the condition of ensuring visual conditions and meeting the needs of the visual users, reducing the time of turning on the lights and saving energy reasonably; using advanced control and energy-saving equipment not only ensures good visual conditions, improves the life of the light source, but also saves energy, Improve the power factor of the line and reduce the power loss of the power grid and lighting lines.

Architecture and lighting should complement each other. Lighting is often a supporting role, and of course sometimes it will be the protagonist. But as a supporting role, it should be willing to be a supporting role and do it properly. Sometimes investing a lot of money and using a lot of high-tech to make the city lights very fancy and gorgeous, will make a city lose its original connotation and charm. What should the night of a city look like? How does the urban night scene reflect the national character and culture? Is it only lively with lanterns, gongs and drums? Can the urban night scene in Beijing have ink and wash feelings, and can it be more elegant? How should the scale of "dynamic" and "quiet" of city lights be grasped? The "movement" and "quiet" of the light should be appropriate. Dynamic things will make people excited. Some commercial buildings and public places that require constantly changing information are themselves places where people gather, a place where people can experience the city`s feasting and feasting. , but it will make people feel very excited, because this is what a metropolis should look like. On the other hand, if it is an ordinary residential building, it would be terrible to design the lights to flash, or if it is a cultural building, it will only make people feel the lack of culture. When dealing with city lights, you should be aware of: learn to be delicate and low-key, and the power of calm is often more lasting and sustainable. My ideal city lighting should be rational and restrained, with soft and warm lighting, appropriately refined and low-key.

1. Determine the desired lighting effect Buildings may have different lighting effects due to their different appearances, or a more uniform feeling, or a feeling of strong changes in light and shade; It depends on the properties of the building itself. 2. Choose a suitable light source The choice of light source should consider factors such as light color, color rendering, efficiency, and life. The light color has an equivalent relationship with the color of the exterior wall material of the building. Generally speaking, bricks and yellowish-brown stone materials are more suitable for irradiation with warm color light, and the light source is high-pressure sodium lamp or halogen lamp. White or light-colored marble can be illuminated with cool white light with a higher color temperature (complex metal lamp), but high-pressure sodium lamps are also used. 3. Determine the required illuminance The required illuminance mainly depends on the light and shade of the surrounding environment and the color of the exterior wall material of the building. Generally speaking, the illumination of the secondary facade is half of the main facade, and the three-dimensional effect of the building can be expressed by the difference in light and shade between the two sides. 4. Decide how to illuminate the subject According to the characteristics of the building and the current condition of the building base, the most appropriate lighting method is determined to achieve the desired lighting effect. 5, choose the appropriate lamps Generally speaking, the light distribution angle of square-shaped floodlights is larger, and the angle of circular lamps is smaller. Wide-angle lamps have a more uniform effect, but are not suitable for long-distance projection; narrow-angle lamps are suitable for long-distance projection, but have poor uniformity when used at close range. You can also choose LED point light sources, line lights, grid screens, wall washers, etc.In addition to the light distribution characteristics, the selection of lamps and lanterns is also a factor that must be considered.

Commercial, leisure, and cultural themed public spaces should focus on analyzing their functions, properties, and categories, and comprehensively consider the characteristics of street lighting, storefronts, urban sculptures, theme squares, advertisements, signs, municipal public facilities, and other landscape elements, and make unified planning. , carefully designed to provide unified and harmonious lighting, play the function and artistic effect of lighting. Lighting can reproduce the volume of large cities and small landscape sketches at night. It can express the sense of scale and layering of objects through factors such as volume, shape, and density in the design. According to the overall design, grasp the details. Shape and theme style rendering. The night scene lighting design of leisure public spaces should first be designed in accordance with the nature, scale and main functions of the square, so that the square can better play its role. The night scene lighting design of leisure public spaces should fully reflect the comfortable atmosphere of the space. In the case of meeting the functional requirements, the lighting brightness should be relatively weakened, and it can play the role of embellishment and basic lighting. Themed cultural public space is more cultural and thematic. The lighting should be aimed at the lighting carriers in the space (theme buildings, landscape sketches, public facilities, greening, etc.) to contrast the night scene lighting, especially landscape sketches, theme buildings, etc. The lighting of the carrier, the choice of lighting angle and light color are very critical. When designing, it is necessary to fully analyze the structure and connotation of the carrier, and combine the virtual and the real, so as to strengthen the cultural theme and create a cultural and artistic atmosphere. It should be noted that in many places, this type of design is likely to cause cluttered light and color, without focus, which affects the design quality and also causes serious light pollution. Surrounded by large-scale urban commercial spaces with dense buildings, important buildings are usually selected as the design expression carrier to use lighting to complement and contrast the building groups, create a commercial cultural atmosphere, and make the urban commercial space environment in the night space more colorful and full of vitality. The lighting environment layout of urban commercial space should also consider the scale and scale of the space, so that the lighting can better decorate the theme, beautify the environment, shape the image, and provide citizens with a place for nighttime activities that is different from the daytime and full of vitality.

Commercial streets are a very important organic part of the city as a whole. Commercial street lighting is based on modern lighting technology and artistic means, under the unified urban planning and design, to realize the reshaping of commercial streets. Commercial street lighting is based on the idea of night landscape planning and design, in accordance with the inherent characteristics of local politics, economy and culture, taking into account the architectural context, terrain, style and nature and the formation of various iconic "objective objects". "Existence", starting from the management regulations and artistic requirements of controlling urban night space, carry out "secondary design" of commercial street at night, and its specific content includes "secondary performance" such as appearance, color, style, material texture, etc. The commercial street lighting planned and designed according to the characteristics of the night landscape, follows a standardized, scientific and artistic track, and performs professional night performance for the street inside and outside and its environment, so that those objects shaped by light can be used in scientific, Three-dimensional lighting in a variety of styles. Many examples of commercial street lighting have proved that the "secondary shaping" business environment completed through "secondary design" and the use of "secondary performance" is very important for inheriting the traditional urban lifestyle, protecting ancient buildings, and improving civilization. , establish a new image, etc. have played an important role. The magical charm of commercial lighting has also greatly increased the sales of commodities and directly promoted the doubling of the commercial economy.

Urban night scene design is based on the analysis of the behavior and psychological state of people in each space of the urban landscape, combined with the characteristics of the landscape and the surrounding environment, and expresses the unique form and spatial connotation of the landscape in the form of light. At night, it reshapes the style of the landscape during the day. , And beautiful unique visual effects at night. The use of lights to reshape the image of the city in the city night scene design is an important manifestation of the characteristics of the city's social progress and economic development. A good night scene design can significantly improve the urban environment, improve the quality of life of urban residents, reduce crime rates, enhance residents' sense of security, highlight urban highlights, and show urban style. Urban night scene design is an organic combination of lighting science and art. It expands the expressive power of the urban landscape and shows the charm of the all-weather city. In order to create unique urban night scene lights that meet the requirements of green lighting and technology, night scene design must follow some scientific laws of urban landscape planning and design, and should respect the urban structure and reflect the inherent characteristics of the city. In order to make the night scene design consistent with the main scene of the city, we should start with the master plan of the night scene, and according to the strategic deployment of the city master plan, combine the current and future urban space layout, and formulate the city night scene from the perspective of the overall art development goal In the future, determine the methods, steps and technical safeguards to achieve the goals.

1. The lighting project needs to be established from planning to design The sequence of the lighting project from the overall to the details, in order to shape the beauty and satisfy the visual art. In this process, our main focus is not "what to do", but "what to control to ensure effective completion". From the point of view of control purpose, it is necessary to avoid disorderly development and excessive development of the lighting project. From the control method, it is necessary to control the lighting level of buildings and open spaces, such as brightness and illuminance. Control the color of light, such as color temperature and colored light; give requirements for lighting methods; provide guidance for detailed planning and design. 2. The lighting project must also reflect the vitality of the city The vitality of a city comes from the needs of construction and management. It should rise from demand to the level of humanistic care, and pay attention to the development of the city. This is based on the pursuit of visual arts, adapting to urban development plans and guiding the transformation of citizens' lives. The lighting project based on this must be consistent with the management of the city and meet the needs of the city. Three, the lighting project should implement the concept of energy saving and environmental protection Lighting engineering should pay attention to two main aspects: one is the application of energy-saving lighting products and intelligent control systems, and the other is to focus on lighting economy. The promotion of energy-saving lighting products has long been recognized in the industry. Lighting designers should use high-efficiency light sources, high-efficiency lamps, energy-saving ballasts, lighting power distribution and intelligent control systems as much as possible, and make full use of natural light.

Light sculpture is a new form of artistic expression that has emerged in recent years. It presents different artistic atmospheres through the interpretation of light, illuminates the night view of city parks, breaks the single park night view appreciation mode, and greatly increases the fun of residents going out at night , And become the highlight of the urban landscape, making urban life more colorful. Light sculpture plays a very important role in shaping the night scene of city parks. It combines the night scene lighting of the park with the sculpture art, gives full play to the charm of artistic lighting, and creates a leisure place with individuality, taste and rich cultural connotation. The public enjoys the beauty of art and culture, which makes residents' lives better. The dynamic photoelectric elements of light sculpture are added to the static sculpture design. The combination of movement and silence makes the sculpture art glow with the breath of a new era. Sculptures with cultural connotation and artistic beauty become warmer and more artistic with the rendering of lighting, which injects rich connotations into the park night scene and increases the utilization rate of the night park. Park lighting sculptures can not only improve the cultural taste of the city, but also become a new business card for urban tourism and landscape construction, and can attract new highlights to attract tourists for night tours. With the advancement of science and technology, the combination of lighting and sculpture will become better and better, which not only has a beautiful appearance, but also can further express the meaning of the work and improve the recognizability of the work.

The garden lighting project integrates into nature through lighting art, realizes the harmony and unity of natural and artificial light environment, so that people can see more creativity and possibilities of light and shadow, and the charm of lighting makes people feel more pleasant. The garden lighting project aims to add color to the monotonous night sky, like a sea of joy, which can relax people and eliminate worries. Garden lighting projects should make full use of natural landscapes, using trees and vegetation as light sources to form a quiet landscape and increase the atmosphere of the garden. The lighting should conform to the theme of the garden, give people a sense of texture and style, and create a warm and bright atmosphere for people's nightlife. The garden lighting project must fully understand the design ideas of each scenic spot, determine the lighting method, and use the changes in light and shade and color to express the garden landscape. Some parts or scenic spots that need to be emphasized need local lighting, such as the gates of the garden, the facade of the main building, sculptures and some ornamental plants, etc., using color and light and shade changes to highlight the beauty or theme of things. The garden lighting project uses water landscaping, shore railings and reflections of trees on the water surface. For some waterfalls, fountains and other landscapes, underwater lighting can be designed. Underwater lighting fixtures of the same or different colors can be specially arranged to illuminate upwards according to needs. The lighting effects are magical and interesting. In short, no matter whether the garden is vigorous or not, its cultural connotation plays a very important role. Therefore, the core of the garden lighting project should be to highlight the theme culture of the garden and enhance the cultural connotation. Through the application and construction of light art such as light sculpture, landscape sketching, light projection, etc., a unique leisure place is created.

1. Park plant landscape lighting needs to pay attention to lighting techniques The basic lighting methods of plants include top lighting and bottom lighting, and more abundant lighting methods can be selected according to the type and location of plants. The position of the light, the light source and the beam angle should be selected and controlled according to the height of the plant, the overall texture and the characteristics of the branches and leaves. Using hybrid methods to illuminate plants can produce a more dramatic effect and produce the effect that the environment needs to form. 2, park plant landscape lighting needs to pay attention to the choice of light source The light color of the light source is particularly important in the park plant landscape lighting. The same plant may have different color appearance and detail performance under different light sources, and it will give people a completely different feeling. Using colored light to illuminate plants is also a more artistic lighting method. White light can express the natural colors of plants more naturally and in more detail, making people feel that plants are clear and transparent. It will be better for plants that need to highlight the color sense. Effect. 3, park plant landscape lighting needs to pay attention to the selection and layout of lamps and lanterns When choosing lighting fixtures for park plant landscape lighting, the main consideration is the light control ability of the fixtures, that is, the beam angle. Generally, the appropriate beam angle should be selected according to the height, density, shape, etc. of the plants to irradiate the plants. At the same time, special attention should be paid to the placement of lamps and lanterns to ensure safety. Where underground lights are used, the temperature of the light-emitting surface should not be too high to avoid burns to pedestrians. Try not to install floodlights directly on tree poles. Overweight lights will adversely affect the growth of trees. Wires entangled in tree trunks will not only cause leakage, but also affect the vision during the day.

The urban lighting project is mainly based on lighting planning, artificially reproducing the natural or human phenomena of the day.
