Now he is a professor at the School of Architecture and Urban Planning of Chongqing University. His doctoral tutor 1 has a background in the central and western regions and an important economic and cultural center in the upper reaches of the river. It is also a historical and cultural city with the culture of the cultural heritage of Rongba, and it has a strong regional cultural characteristics and heavy weight. The word water lantern refers to its beautiful night scene, which is the ten scenes of the Bayu. At night, the stars are dotted with stars, and they are reflected in the vast rivers. The landscape lamps together constitute a landscape painting with endless aftertaste. The scenery is amazing and enjoys a high reputation at home and abroad.
From the topography and geomorphology, Chongqing provides a unique carrier for urban nightscape lighting with its topographic features surrounding the peaks and peaks of the two rivers. Chongqing Sushan City, the city of Jiangcheng, is located at the intersection of the Changjiang River and the Jialing River. The city is built on the mountain, the roads are drowning, the buildings are scattered, and the sense of space is very rich. On the other hand, the terrain is fluctuating. It has formed a multi-level and multi-faceted viewpoint of Gaofu and Riverside, and has become the unique advantage of the construction of the night view of the mountain city. Since 995, it has implemented seven brilliance projects in the main city, and its night illumination has been greatly improved, but there are still many Asked about the lack of scientific and rational planning and unified construction of the building alone. Make the city's lighting environment overall poor, content list. Lack, owe; the brightness distribution of night lighting is unreasonable, the illumination in some areas is dark, and some important buildings are caused by excessive light pollution and energy waste. The night lighting does not reflect the inherent 4 laws of Chongqing, lacking dynamics and high Scientific lighting means, improper use of color, poor artistic effect, not suitable for its own connotation.
In order to live up to the reputation of the night view of the mountain city, promote the development of urban tourism resources, and shape the image of the municipality of the municipality directly under the central government. Entrusted by the Chongqing Municipal Party Committee and the Municipal Administration Committee, we are from the South Bank Tree Observation Deck of the most important viewpoints in the urban area. K, systematically plan the night view of the city in the main urban area within its line of sight and make architectural lighting design for the important nodes.
2 Night lighting planning and design goals and principles In the planning and design, we draw on the domestic night lighting concept, and follow the following principles to make overall considerations for the night scene components of the planning area, such as mountain river buildings and structures, and point-to-face combination. Coordinating, and changing the key points to render the group center node, relatively weakening the group combination, highlighting the key points, concealing the unique combination of landforms, enriching and reshaping the urban contour line outline and water contour, and strengthening the layering. Form a three-dimensional night landscape; planning and design tour (4) through high-tech means to strive for the perfect combination of technological advancement and artistic innovation. Implement green lighting plan, reduce light pollution, achieve environmental protection and save energy, and achieve sustainable development of night lighting; night, 1 lighting planning specific measures 3.1 main view area façade stratification from the unique terrain of the main city, combined The different characteristics of the current building are within the scope of the plan. The carrier is widely distributed. The first level is the skyline of Yuzhong District; the first level is the buildings along Jiefang Road and Shaanxi Road; the first level is along the Changbin Road complex; the first level is the river embankment along Changbin Road; the first level is Nanping. New Street marble stone construction 1. Through the stratification of the façade, the horizontal direction tends to be unified, and the longitudinal direction is rich in change effect, forming a mountainous night landscape with a clear overall focus and clear focus. The skyline of the Yuzhong District at the first level is mainly composed of high-rise buildings, which is the priority to be dealt with in this plan. Adopting, yellow light to regulate the skyline, åŸ use the fading technique to gradually move down, through the gradual change of brightness color, the climax of the current night scene. For this layer of electricity to be 0 points, the use of red and blue colored light and neon dynamic space lights into the hall interspersed with the embellishment, shaping the skyline of the changing and changing. In order to avoid light pollution to the households, the white house is mainly used for natural lighting. The level is gorgeous. Most of the façades of the first-level buildings are not ideal. Therefore, some buildings with certain connotation and strong individuality, such as the Huguang Hall, will be selected for key lighting, while other buildings with lower grades will adopt the method of weakening the illuminance of the façade. It is hidden in the night. The first level is supplemented by other shades of orange and yellow light, which not only strengthens the two rivers and echoes the skyline. The specific measures are floodlighting on the riverside embankment of Binjiang Road, color lighting on the riverside barge, and mobile color fountain in the river. The above-mentioned chemical carrier and the milk-sucking structure are used to strengthen the environmental characteristics of the central part of the Suizhong Peninsula.
The first level is located at the side of the viewing area, the role of the scene, so it should not be too bright, so as not to lick the sheep. The plan only highlights several mountain walks in the close-up, with green floodlights reflecting the greenery of the mountains, and outlines several ancient buildings on the hills, setting off the magnificent artificial landscape on the other side. This plan seeks to pass the night scenes of Chongqing with a landscape of mountains and waters.
3.2 Planning area lighting classification According to the nature of the building group in the planning area, the important group nodes and the main viewing area are illuminated and graded, and their brightness levels are determined separately to avoid the feeling of monotonous dullness caused by brightness. There is a focus on the whole, and there are bright spots in the area with the main night view.
The planned brightness is divided into a relative level, and the top level of the highest level of the 10th generation of the Peninsula flag at night. According to the regulations on night lighting such as 01, the weather and energy requirements for environmental protection, we specify the absolute brightness of the brightness level corresponding to 48, 2, and in turn specify the other, the absolute value of the brightness of the level. The Jiefangbei Jiaochangkou Linjiangmen and other urban nodes are the most prosperous commercial districts in the city, and the terrain is relatively high. There are many high-rise buildings. We have made key treatments with a lighting grade of 8.9. The Chaotianmen and the North Bridge of the Yangtze River Bridge are all tourist traffic nodes, and they are located on both sides of the viewing range. They are the key points for the lighting of the planning area, taking 7 as its lighting level. Although the area along Jiefang Road and Shaanxi Road is in the center of the viewing area, its buildings are mainly residential and should not be too bright. The area along the Changbin Road is the bottom line of the peninsula. It plays an important role in the overall view of the landscape. It should be treated as a sub-key. The lighting level is 6. The upper Xinjie area is the edge of the viewing area, and the brightness should be reduced. Its lighting level is 22.
In addition, in order to avoid the nightscape of the 4 prominent city features due to sudden changes in brightness, each city has its own characteristics in terms of cultural and traditional topography and other architectural forms. Therefore, in the lighting design, the characteristics of the city itself should be explored and Highlight innovation to form a unique style, which is the benchmark for creating the overall effect of the city's night scene.
4.1 Strengthening the city towel hub The Chongqing city skyline is quite rich. The outline of the mountain is intertwined with the multi-level architectural contours to jointly build the characteristics of the mountain city. This nightscape lighting design is designed to meet the advantages of nightscape lighting, to strengthen the important and beautiful characteristic contours of the city, to weaken the spots that hinder the visual and damaging visual effects, and to create more through these artistic processing. Charming mountain city night view.
4.2 Highlighting the urban structure In the night scene, it is the key to attracting tourists to clearly reflect the main nodes of the city and the important roads to show the urban context. Therefore, in the lighting design, the various elements of the city should be carefully treated, and the urban structure is highlighted and easily identified by the comparison and coordination of the point-like linear features.
This plan will be the city's landmark nodes, such as the Hongxing Pavilion Liangjiang Pavilion at the commanding heights of the Jiefangbei Commercial Street Peninsula in the center of the Chaotianmen Square Peninsula at the junction of the two rivers, the North Bridge Head of the Yangtze River Bridge and the front square of the railway station station. The line is illuminated by Changbin Road road lighting and river embankment. The bridge and street lighting of the Yangtze River Bridge form a solid line. The neon lights on the top of the high-rise buildings on the peninsula form a dotted line with several bright lines and multiple bright spots embedded in the home lighting. On the background of the tens of thousands of lights formed, the urban structure of the main city is vividly displayed in the night.
4.3 Creating a dynamic urban landscape into a constant case is likely to cause visual fatigue. This is the important guarantee for the formation of vivid night scenes. In the lighting design, the potential of urban landscape factors should be fully explored.
In this plan, a space light ball is set up above the Jiefangbeihuan Island to change the shape. In the important buildings, the neon light translucent lamps and the follow-up contour lights are set in color, and the floating island color fountain is set on the river surface. The lighting of the high-rise buildings on the river cableway, such as elevators and vehicles and ships, is used to form a dynamic and static combination of rich and lively overall landscape effects.
4.4 Using high-tech to apply high-tech to the design of night scenes, it can not only reflect the characteristics of the metropolis, but also achieve the novel and lively artistic effects. In this plan, we use the following technology: 1 fiber technology, which is characterized by It is decorative, safe, waterproof and has a long service life. It is planned to adopt this technology on the glass curtain wall of important buildings such as Chaotian Hotel, and it will give people a magical and beautiful artistic enjoyment through the regular changes in the brightness and color of the luminous points.
(2) Use bright and colorful laser beams to move regularly in the night sky to form a case to enrich the skyline, such as the top of Zhongtian Building. For some important buildings along the commercial pedestrian street, the laser beam is projected onto the mountain wall to form various cases and texts to enhance the dynamic and beautified night scene.
The illuminating pole tube can be assembled into a public place where people flow in a commercial street station, such as a wharf hotel, and the like, can be assembled into different areas of display screen.
The holographic technology, on the solid walls of some important buildings on both sides of Jiefangbei Commercial Street, the shape obtained by holography under the illumination of the laser, produces an image that is synchronized with the original and has a three-dimensional effect.
5 heavy-duty building night lighting design 5.1 design points building landscape design, should emphasize the coordination with the surrounding environment, including it into the night view planning. In addition to playing a prominent point, we must also adjust the tone to ensure the overall effect of the night zone. 5. In addition, the choice of lighting should be consistent with the nature of the building features, to enhance its inherent characteristics through design, to avoid abuse of lighting, such as office buildings and commercial Architectural lighting should have a large difference in color brightness and lighting fixture selection. At the same time, the lighting design must consider the interaction between the light source and the material.
5.2 Lighting design measures Building lighting lighting methods mainly include contour lighting, floodlighting, and high-tech lighting. In the specific lighting design, we can reasonably combine according to the characteristics of various lighting methods to shape the building ceremony in various ways.
