Beijing Tianningsi Bridge Night Lighting Project Beijing Liangye Lighting Engineering Co., Ltd. Tianning Temple Bridge is an important hub connecting West Railway Station, Guang'ankou to Fuxingkou and Qiankou. The length of the bridge is 5 meters and the traffic volume is large. The bridge body is a cloud overpass, two main bridges, and one side road bridge. The shape is majestic and magnificent.
In April 1999, the Beijing Municipal Commission of Management presided over the bidding for the night view of the bridge. Finally, the design proposals of Beijing Beixong Electric Co., Ltd. and Beijing Liangye Lighting Engineering Co., Ltd. jointly won the bid. The division of the bridge, 23 layers of Beixong design and construction, the auxiliary bridge was designed and constructed by Beijing Liangye Lighting Engineering Co., Ltd. The 23-story lighting is illuminated by red, yellow and white color lights, and the auxiliary bridge is illuminated by white light. There are rivers passing under the bridge, and the decorative lights on both sides of the river are designed and constructed by Beijing Liangye Lighting Engineering Co., Ltd.
Characteristics of 2 Tianning Temple Bridge Analysis There are rivers passing under the Tianning Temple Bridge. There are Lanzhou Interchanges on the road. The structure is complex and the space level is rich and magnificent. This creates favorable conditions for the three-dimensional sense of the night light of the bridge and the multi-layer lighting effect.
The Tianning Temple Bridge is different from the overpass. The length of the bridge is long and the height is high. It is difficult for the main person to look at the whole bridge in the vicinity, but the whole picture must be seen in the movement. Sending requires the designer to have a larger lighting scene and continuous visual effects.
Due to the multi-level bridge, the shadow cover is more serious, and it is necessary to illuminate the pillars and the site lighting under the bridge.
There are no large green belts in the surrounding environment of the bridge, but there are many small resting places. Therefore, in addition to the lighting facilities of the bridge itself, the integration of lighting and rest places should be considered.
The background of the whole bridge is dark, and the beauty of the environment should be set off. In addition to illuminating the structure of the bridge itself, the lawns on both sides of the river bank should be brightened, and the lighting landscape and the shape of the lawn should be set up to beautify the artistic conception of the bridge.
3 Advantages of using a light bulb with illumination The bridge bar is low but long and has a limited distance from the illuminator. With the use of point light source illumination, the cost is high and the energy consumption is large, and continuous uniform illumination on such a length cannot be realized; due to the lateral illumination, the vehicle or pedestrian on the bridge surface does not have any glare interference; and from other parts, only when the bridge and the main body In the case of near vertical and the viewpoint is higher than the bridge surface, the residual light after partial blocking by the grille will cause weak dawn. According to the field analysis, there are almost no cases in which the above conditions are satisfied along the driving direction, and only in the partial arc angle when the side angle of view is greater than 60 degrees.
The strip light source is the most utilized here, and the energy consumption per unit length is also the smallest. Although the secondary investment is large, the subsequent operating costs are lower.
The high color temperature of the light bulb forms a white light band, conspicuous, expressive, and elegant.
Since the luminaire itself is hidden between the guardrail and the bridge, the daytime landscape is not affected.
This kind of smart light has been successfully applied to the largest single building Chinese pavilion in Kunming World Horticultural Exposition Park, achieving excellent results. This type of lighting was also applied at the arrival and exit of the new terminal of the Capital Airport.
Due to the difficulty in starting the light at low temperature, the light efficiency is reduced. When manufacturing the lamp, we take the following measures; it is a high-performance electronic ballast, the second is the sealing and heat insulation of the luminaire, and the third is the long-life import. Light tube.
4 The bridge column is a support point in the vertical direction. The patchwork runs through the four levels, just like the music's staff, which best reflects the theme of the building is silent music. This scheme intends to use the 250400 chemical pressure steel lamp to carry out local illumination from top to bottom of the bridge column, and dye the warm yellow vertical lines on the horizontal lines of white or warm white. Due to the low color rendering of high-pressure steel, Keke can conceal the roughness and defects of the bridge body to a certain extent, making it possible to recreate the building by lighting. At the same time, the overflow light of the downlight fixture can play the following role: eliminating the shadow cast by the separation layer of the bridge body on the lower layer and eliminating the blind zone; secondly, implementing limited fill light on the bottom road surface, the illumination is between 20 and 1 Easy to walk and rest.
5 Rivers on both sides of the slope landscape lighting The turf on the slopes of the two banks of the river is a large area of ​​gray concrete in the entire bridge area. According to the overall design illuminance requirements, and taking into account the beautiful environment of the river itself, the illumination here should not be too embarrassing.
The shape of the swallow on the lawn is made of red and yellow with a beautiful light, highlighting its flat shape on the green lawn.
The lawn lamp scheme is planned to be installed on the banks of the river every two meters. The two-way bean sprouts turf lamp is specially made by the company. The lamps themselves are low and the light is obliquely down, which will not cause glare to the vehicle. According to the structure and layout of the luminaire, we can imagine that the overall effect will be a soft spot like a staves, with a strong sense of rhythm, which is very harmonious with the above overall effect.
6 Conclusion After the completion of the night lighting construction of Tianningsi Bridge, it achieved good results. Due to the different upper and lower layers of the upper and lower layers, the upper layer is discolored, the lower layer is discolored, the whole bridge is rich in color and the lights are beautiful; the auxiliary bridge railings are bright and bright, and the shape is clear and beautiful. . The scenery on both sides of the river bank is pleasant, and the reflection in the water makes the whole night scene more beautiful, creating a long-term attraction for the Beijingers. This successful night scene case will inspire us to continue to struggle and work hard to create even better results.
