Can anyone tell me about the bridge lighting benefits, that is, the overview, the urgency

Excellent bridge lighting facilities can provide safe, fast and comfortable visual conditions for vehicle drivers to drive at night, so as to ensure the safety of vehicles and pedestrians, facilitate people's lives, prevent criminal activities, and ensure the safety of people and property. It is conducive to the improvement of the city's night image and the effect of beautifying the urban environment.

1. Principles of bridge lighting design.

Bridge lighting design should follow the basic principles of safety, applicability, economy and beauty:

1) All lighting and lighting sources shall not affect the safety of aviation, ships, vehicles and pedestrians.

2) People-oriented, pay full attention to people's visual comfort, and avoid light pollution.

3) The bridge is connected to the urban arterial road, which not only undertakes the traffic function of large flow, but also is the main landscape axis of the urban area. Therefore, the lighting design of the bridge should first ensure the traffic lighting of the bridge deck, and then the landscape lighting of the bridge body.

4) Each bridge has its own morphological characteristics and strong characteristics, distinctive style, modern and classical contrast, which should become the elements of night scene lighting rendering.

5) Consider different directions and angles to carry out the bridge lighting design, select the appropriate brightness, and the lighting effect makes the bridge highlight its size and details in the environment of three-dimensional space; The overall artistic shape of the bridge is combined with a single structure with characteristics.

6) A variety of light sources with different functions will not interfere with each other, resulting in negative effects such as diffraction, flood, and chaos.

7) The lighting facilities and lighting pipelines are as concealed as possible and cannot affect the daytime landscape of the bridge; The shape of the lamp should be novel, the lighting should be efficient and uniform, and the installation and maintenance should be convenient.

The purpose of bridge decorative lighting design is to highlight the overall image and architectural characteristics of the bridge through the intensity and color change of light, and to achieve the effect of beautifying the environment. Therefore, the bridge lighting design should also follow the following principles:

1) The principle of energy conservation should be followed;

2) The design should fully consider reducing the cost of lighting, including the initial investment and operating costs;

3) The design should fully consider the all-round management factors such as maintenance, repair, cleaning and replacement.

2. Key points of bridge night scene lighting design.

Although the basic lighting of the bridge can play a certain role in the night landscape of the bridge, the night lighting of the bridge is an organic combination of the science of lighting and the art of bridge architecture. It expands the landscape performance of the bridge, displays the aesthetic characteristics of the bridge around the clock, and plays an important role in expressing the spatial hierarchy and depth of field of the urban nighttime landscape. Therefore, the design should focus on its own characteristics, and show the personality and essential beauty of the bridge in the way of point, line and surface.

The night scene lighting of the bridge should restore its architectural artistic beauty, and it should not be lit throughout, and there is no sense of hierarchy. In order to carry out targeted lighting design according to the shape characteristics of different bridge types, it is necessary to master the elements of the bridge, such as the characteristics of the main cable, bridge pylon, cable-stayed cable, guardrail, longitudinal beam, bridge arch, bridge pier, etc.

The morphological method is to use static or dynamic light, and dynamic light is to express the dynamic effect of the building with flowing light.

The principle is the same as that of traffic signs, which is to reflect the light so that people can see it from afar.

The bridge lighting project should do a good job in these points:

Lamp placement: the height of the bridge lighting lamps and lanterns directly affects the actual effect of the bridge lighting project and the difficulty of after-sales maintenance management.

Lighting protection: the lighting project used in the lamps and equipment, most of the open-air operations, road and bridge lighting lamps and equipment installation process, to fully do a good job in lamps and equipment line anti-aging, rain and other work.

The main and secondary objects of the bridge lighting design are mainly the night view of the bridge, which should restore its architectural artistic beauty, distinguish the primary and secondary, and not be integrated and bright, and carry out different lighting designs with the characteristics of different bridge types.

Bridge features: With lighting design as a technique, combined with the basic principles of bridge aesthetics and landscape design, the structural characteristics of the bridge are highlighted, reflecting the modeling characteristics of the bridge itself at night, and highlighting the unique form and momentum of each bridge.

First, the landscape lighting project should highlight the structural characteristics of the bridge.

Using light art, the basic elements of the point, line and surface of the bridge are combined, and the color gradation of the bridge at night is increased in the form of a digital dynamic light color system. Fully consider different directions and angles to design the landscape lighting of the bridge, and select the appropriate brightness to make the bridge highlight its parts or details in the three-dimensional environment, so as to express the combination of the overall artistic shape of the bridge and the unique structure.

Second, the bridge landscape lighting project should control the projection angle and range.

In order to establish the composition, sequence and rhythm of light, render the effect of spatial changes, improve the proportion of space, increase the level of space, pay attention to the coordination of local lighting and overall lighting, emphasize color performance, and express the three-dimensional sense of the bridge.

Third, the bridge landscape lighting project should pay attention to the construction quality.

Carefully consider the light source and lamps of functional lighting and landscape lighting, and when installing, it is necessary to prevent the brightness and light color of functional lighting from attaching to the field of vision of motor vehicle drivers, strictly control glare, reduce light pollution, and reduce the incidence of traffic accidents. At the same time, care must also be taken not to affect the navigation of ships under the bridge to ensure the safety of ships.

The engineering elements of bridge lighting should follow the principle of energy saving, and consider reducing the cost of lighting, and at the same time, fully consider the elements of maintenance, cleaning, replacement, etc.

2.By selecting point luminous lamps, linear light luminaires, flood projection lamps or light source type green lamps, etc., the advanced lighting control mode is adopted to flexibly control the entire lighting system, so that it can switch a variety of light color changes and brightness changes for the bridge at different times and seasons. At the same time, it is necessary to consider whether these lighting interfere with traffic indication lighting, whether it meets the road lighting code and other issues.

3.Combined with the basic principles of bridge aesthetics and landscape, the structural characteristics of the bridge are highlighted, and the dynamic and static landscape lighting is used to highlight the charm and momentum of the bridge, so as to expand the landscape performance of the bridge and show the aesthetics of the bridge.

1.The lighting engineering company should follow the original style and structural layout of the bridge, and the bridge can be combined with points, lines and surfaces, and then highlight the characteristics of the bridge through the combination of dynamic and static, so as to interpret the beauty of the bridge itself.

2.As a traffic artery, the bridge needs to avoid over-lighting caused by the pursuit of beauty, so the lighting engineering company should design the light environment according to the scientific scale, and measure the illumination, brightness distribution, uniformity of illumination, shadow, glare, light color and other lighting quality indicators.

3.The bridge lighting project is different from other lighting projects, most of which are open-air operations, and need to be fully done in the process of installing lamps and equipment.

1.Determine the position of the lamps and lanterns Because the bridge lighting project is the construction of the new lamps and lanterns after the bridge has been completed, the lighting project mainly focuses on highlighting the shape of the bridge and achieving the purpose of beautifying the night view of the city. 2.Tray and conduit laying...

The lamps generally used in bridge lighting projects have these:

1. LED buried light.

LED buried lamps have a wide range of applications, both square and round in shape, mostly made of stainless steel, solid and durable, strong water resistance, good heat dissipation performance, sealed with silicone ring, waterproof and high temperature resistance, durable and oxidation resistant;

2. LED flood light.

LED flood lights, also known as spotlights; It is capable of aiming in any direction and has a structure that is not affected by climatic conditions; Luminaires that make the illumination on the specified illuminated surface higher than the surrounding environment, so almost all large-area lighting fixtures used outdoors are called flood lights.

3. LED wall washer.

LED wall washer, also known as linear LED flood light, because its shape is long, also known as LED line light, its technical parameters are generally similar to LED flood light, relative to the circular structure of LED flood light, LED wall washer strip structure of the heat dissipation device appears to be easier to deal with;

4. LED point light source.

LED point light source refers to the light source with LED as the emitting body, which is one of the artificial electric light sources. It has an important position in the design of architectural lighting.

5. LED strip light.

LED strip light refers to the assembly of LED on the ribbon FPC (flexible circuit board) or PCB hard board, because its product shape is like a ribbon name.

General lighting engineering companies can design lighting renderings.

1. Combined with the basic principles of bridge aesthetics and landscape, highlight the structural characteristics of the bridge, and the lighting design should focus on its own characteristics, in the way of points, lines and surfaces. The landscape performance of the bridge is expanded, showing the aesthetics of the bridge.

2. As a traffic artery, the lighting of the bridge must meet the road lighting specifications to ensure the safety of traffic, and the lighting fixtures and lighting brightness must comply with the relevant regulations, so as not to form glare on the traffic and prevent the dazzling effect of pedestrians on the road.

3. The rapid development of bridge structure technology also creates a new stage for landscape design, with lighting as the main means combined with innovative design, and the landscape lighting pattern with dynamic lighting and static lighting highlights the key points of the bridge, and highlights the charm and momentum of the bridge with art and innovation.

The height of the position of the bridge lighting fixtures directly affects the actual effect of the bridge lighting project and the difficulty of after-sales maintenance management. The lighting lamps are arranged too high on both sides of the bridge, so that the light radiation and reflection effect are not obvious, and if the lighting lamps are too high, the lighting lamps are susceptible to external damage, and the potential safety hazards and operation and maintenance costs are increased. If the installation position of the lighting fixture is low, the difficulty of construction operation and future maintenance increases, and the bridge will be poor due to the increase of the influence surface of the light.

What do you need to do to ensure that you don't waste resources?

1.Combined with the basic principles of bridge aesthetics and landscape, the structural characteristics of the bridge are highlighted.

2.The lighting aesthetics is supplemented by the basic elements of the bridge, and the combination of points, lines and surfaces constitutes the lighting system.

3.Increase the nighttime color gradation of bridges in the form of digital dynamic light color system lighting.

4.Fully consider different directions and angles for the night landscape lighting design of the bridge.

1. Determine the position of the lamp.

Because the bridge lighting project is the construction of new lamps and lanterns after the bridge has been completed, the lighting project mainly focuses on highlighting the shape of the bridge and achieving the purpose of beautifying the night view of the city.

The level of the lighting fixture layout directly affects the actual effect of bridge lighting and the difficulty of maintenance management. The lamps and lanterns are arranged too high on both sides of the bridge, and the light radiation and reflection effect are not obvious; At the same time, if the position of the lighting fixture is too high, the lamp is vulnerable to external damage, and the potential safety hazards and operation and maintenance costs increase. The installation position of the lamps and lanterns is low, the difficulty of construction operation and future maintenance is increased, and the bridge has a poor long-distance effect due to the increase of the influence surface of the light.

2. Laying bridges and conduits.

When laying bridges and conduits on bridges, attention should be paid to the damage and impact on the existing bridge structures during the installation of bridges and conduit supports. Therefore, during the construction process, the waste holes generated in the installation of the bracket are closed with epoxy mortar in time to reduce the damage to the structure.

3. Installation of lamps and equipment.

The lighting and equipment set up in the bridge lighting project, different from the working environment of the general lighting fixtures, most of them are open-air operations, and the installation process of bridge lighting lamps and equipment should fully do a good job in the anti-aging and rainproof work of the lamps and equipment lines.

4. Anti-theft facilities for lamps and equipment.

Bridge lighting construction is the construction work of the new lighting installation project outside the existing structure, the new content is all surface-mounted, and the specific amount of some lamps is small, and it is inevitable to be damaged and affected by external man-made beings. In order to maintain the safe use of lamps and lanterns and reduce damage, safety fences and protective covers are added to some lamps and lanterns to carry out necessary protection for lamps and conduits to reduce man-made damage.

5. Safety management of bridge lighting construction.

The lighting construction of urban bridges is difficult to manage safely. On the one hand, as the main passage of the city, the bridge has heavy traffic and large traffic volume, and the construction is seriously disturbed by the outside world. On the other hand, there is water flowing through under the bridge, and the bridge lighting is to lay lamps on both sides of the bridge, which needs to be in the air and work at height, and the danger is greater.

Therefore, in the process of lighting construction, safety management is difficult and safety production requirements are high.
