Our team embarked on a study tour in Australia and New Zealand. In this event, we explored cities or attractions such as Sydney, Melbourne, Auckland, Brisbane, Gold Coast, Warner Bros., Rotorua, Hunter Valley, and Sydney Opera House. In this activity, I saw the roads, road lighting and night lighting of urban cities in economically developed western countries, municipal construction of urban greening, and industrial and civil construction. From the experience to the design of road lighting and night lighting Many aspects are well worth learning about their humanistic ideas and advanced technologies. Let's talk about some of the experiences after the Sydney night view.
The importance of urban night lighting
Urban night lighting is an important part of the urban landscape, and it is a nighttime comprehensive system composed of many elements of nature and humanities. Urban night lighting is the use of technical lighting as the carrier in the urban space environment under the night, and the artistic creation of the urban night landscape environment is the creation of unique urban landscape resources and artistic re-creation. The nighttime reappearance of a city's daytime landscape pattern can make the city's night sky more colorful, life more intense, and the business economy more prosperous. The development of urban night lighting can reflect the historical and cultural heritage of the city to a certain extent, the social and economic development, the living standards of the residents and the government's ability to build cities. It has important social, economic and environmental significance.
People's appreciation of the night scene seems to be an indispensable tourist project. The huge luminous five-color ring on the Sydney Bridge and the night view of the city of Sydney Harbour are long-lived in the hearts of people all over the world.
Inspecting in Sydney, especially at night, the deepest feeling is the lighting conditions and lighting effects. The street lighting here and the window lighting on both sides of the street are extremely obvious. The orange lights tend to emerge from the transparent window, revealing various objects inside and standing or sitting and shaking. This kind of light brings a warm atmosphere to the city, attracting pedestrians to stop and gather. Even at midnight, where the shadows are scarce, the lights on the street of the town will still give a warmth to the people driving through it, encouraging to find the light that belongs to them. It can be said that urban night lighting is an important time and space to display the image of the city.
With the continuous development of the world economy and rapid social progress, the construction of urban lighting facilities has increasingly attracted the attention of cities in various countries and the extensive attention of all sectors of society. Urban night lighting is a kind of lighting technology that uses lights to shape the image of the city at night. It is also an art that shows the development of the city and reflects the personality of the city. Night lighting has been used since ancient times. It was mainly used to set off festive atmospheres for holidays and businesses. For example, the Lantern Festival held a lantern commemorative meeting. Various lanterns were hung at the meeting and the lights were shining. With the advancement of science and technology, the development of society and the improvement of people's quality of life, night lighting has been further developed. Night lighting, for the landscaping of the city, improve the city's visibility, optimize the living environment, travel environment, improve the investment environment, ensure urban night traffic safety and social security, and promote the development of tourism, transportation and other industries play an active role. .
Urban night lighting performance
Typical urban form: landscape city and natural conditions, landmark city conditions, section city conditions, municipal city conditions, graphical city conditions, and comprehensive urban conditions.
There are many ways to express urban night lighting: the performance of night lighting should be around the theme, in the form of simile and metaphor, with direct and indirect lighting methods. After determining the overall guiding ideology, it is necessary to give the shape effect and arrange the elements in space. There are many ways to express night lighting, mainly floodlighting.
Contour lighting, internal light, neon lighting, tree string lighting and light box lighting. There is no general mode for the selection of the method. It depends on the specific situation of the subject, and the appropriate method is selected according to the function, characteristics, style and surrounding environment of the object.
Sydney night lighting performance
Sydney mainly has:
Floodlighting: Night lighting in the Sydney Opera House is illuminated by floodlights outside the building. From the effect of night lighting, the highlights of the opera, the highlights of the opera, one virtual and one real, one bright and one dark, one light and one heavy, its characteristics are obvious, which makes people have a wonderful echo in the contrast.
Inner light-transparent lighting: For example, the night scene in Sydney uses the room window of the building to design the night scene, allowing the light to pass through the window to form a so-called inner light-transmitting illumination, which is a typical lighting method in night lighting. This kind of lighting can create a bright, transparent and deep inner light effect into the night, and the building window reveals bright light, creating a vibrant night city scene.
Advantages of internal light transmission:
1. Eliminate a large number of lamps exposed to people's sights due to night lighting to beautify the city.
The first is that there is no need to install lamps outside the building to ensure the appearance of the building is neat. When designing the façade lighting of a building, if floodlighting is used, many luminaires are usually installed. In most cases, these luminaires should be exposed to the outside, or installed on the ground support, or installed in the building. On the surface, although the building components and the changes on the facade of the building are used to hide the lamps, it is generally impossible to ensure that the lamps or parts thereof are not fully visible, and the exposed lamps destroy the neatness and perfection of the building landscape. Looking at the night lighting of various cities, this is a very prominent problem. If this is the case, such lighting fixtures will inevitably become a very negative impact on the development of urban landscape lighting in the construction of urban landscape environment. Since the inner light-transmitting illumination is to install the light fixture indoors, this problem will be avoided in the light-transmitting illumination.
2, the use of internal light illumination can maximize the impact of glare.
Floodlights used for facade lighting generally have a high surface brightness. Once they enter the line of sight, they will have a dazzling feeling. When flooding the building wall with floodlights, no matter how the lamp position and the beam angle of the lamp are selected, Controlling the projection angle may cause more or less glare interference in certain directions or certain locations, especially for more serious light damage in the illuminated building room; internal light transmission is selected due to low power The low-intensity light source, while the lighting fixture can be installed in a good concealed manner, thus making it an illumination method with very little glare interference.
3, the inner light transmission can minimize the light pollution to the urban environment and the urban sky.
Floodlighting on the facade of a building creates a nightscape effect by reflecting and scattering light from the building wall. Normally, the facade lighting is projected from the bottom to the wall, and a large amount of reflected light is directed at the opposite direction of the line of sight. The sky not only pollutes the sky, but also weakens the design effect of the night scene. If the wall surface is a glazed brick or a metal plate with a high reflectivity, the amount of reflected light that hits the sky will be more. The night sky lighting caused the city sky to shine has become a prominent negative problem. The direction of light used for internal light illumination is just the opposite, because its light is concentrated in half of the space below the horizontal line, effectively improving the light efficiency, making the design light of night lighting mostly effective. In the landscape lighting, we often discuss green lighting problems. In fact, the rational use of the internal light transmission design in night lighting may be an effective manifestation of the green lighting concept.
4, the inner light transmission can create more landscape changes.
Since the inner light-transmitting illumination is designed as a single unit as a separate unit, and then constitutes a whole landscape, the mutual combination of different units can evolve a lot of changes, which makes the design of the inner light transmission. The night landscape can evolve a lot of patterns, which can better satisfy the people's desire to seek new changes and hope to see more scenery, so that the buildings can display their own images with different night scenes at different times. To set off the atmosphere.
5, convenient maintenance and management, equipment safety.
External projection lighting sometimes installs the luminaire on the building body, which makes maintenance and repair a great inconvenience; the outdoor environment easily causes the lighting equipment to be fouled, which increases the workload of maintenance; sometimes the illuminating equipment is mounted on the ground. In addition, it may increase the probability of human damage, and at the same time bring hidden dangers to environmental safety. Although the lighting facilities are arranged in many places and are relatively scattered, they are mostly located in the indoor window, and the maintenance is relatively easy; the lighting equipment installed indoors is not affected by environmental pollution or artificial damage, increasing the period of use. .
6. Beautify the city and save investment.
Since the inner light-transmitting illumination utilizes the original indoor lighting equipment, which is both an integral part of the normal lighting and an integral part of the night lighting, the night lighting does not need to additionally set the night lighting fixture and the control system for the night lighting. In addition to the night lighting, it also saves investment in equipment for night lighting, so it not only beautifies the city but also saves investment.
Some experiences after studying and examining:
1. After studying and studying in Sydney night scene lighting, night lighting should be incorporated into the overall urban planning, unified construction, unified management, and lack of close connection with the socio-economic development model. The development of the economy has led to changes in the urban spatial form, and the development of urban night lighting should also be closely followed.
2, night lighting, the effect of the first to bring comfort and beauty to the viewer, while at the same time to bring comfort and beauty to the viewers should also save energy, which is probably the first thing that every night lighting designer should consider problem. In the design of night lighting, some cities are not designed by the designer but the competent department is planning and guiding. Under the premise of the night scene lighting project, without considering the city's natural and human elements, the urban space environment under the night, blindly Emphasize the grandness and brightness of the night scene lighting, causing serious dislocation of the main body of the city night lighting environment. The function of night lighting is not to brighten, but to create a living environment that reflects the urban night environment and is beneficial to the physiology and psychology of the citizens. The basic starting point is to create a leisure environment and create a different color of leisure space for different groups of people, reflecting " The principle of people-oriented.
3. Light pollution problems in night lighting. After the city's night lighting design, the city becomes a beautiful city, but the light pollution caused by night lighting has affected people's lives and health. The high-brightness light environment brightens the interior and affects people's sleep quality. This is probably the first question that every night lighting designer should consider.
4. Through the study of urban night landscape design, it should be recognized that the night space of the city is different from the urban functional space during the day, and it is not a simple lighting plan. It is part of the urban space and should better optimize our urban functional space. Create a comfortable, colorful, vibrant city night lighting environment.
