Three common misconceptions about bridge lighting design

Bridge lighting design is a hot topic in recent years, rapid development. With the deepening of China's urbanization and infrastructure, has developed from simple pedestrian bridge, overpass bridge is more complex and cross-sea bridge across a river, its form and function has become increasingly diversified.

bridge is not only a transportation hub, more a symbol of the city development of economy and technology level, often become a landmark landscape. Therefore, the nightscape lighting has become one of the important landscape of urban nightscape lighting. In long-term bridge lighting design work, intellectual beauty lighting designers have found some common misconceptions, influence the bridge lighting effect.

one of myth, road lights too much, influence the whole lighting effect.

most of the Bridges in the city with motor vehicle driveways, non-motor vehicle driveways, pedestrian access, even the function of the railway channel. Lighting design of this kind of Bridges usually continues road lighting design specification, extend street light from the street to the bridge, and throughout the whole of the bridge. It is meet the requirements of the functional lighting, but also caused the whole lighting effect of the bridge.

the reason on the one hand is the landmark of the bridge lighting have been fully, and even the detail structure of the bridge structure of the elements have been illuminated, the bridge of the decorative lighting for pavement also provides indirect lighting also; Motor vehicle itself, on the other hand, also has its own lighting system, for a motor vehicle on the roadway driving, actually there is no shortage of illumination.

so, bridge street lamp design how can not only ensure traffic safety, and reduce the impact on the bridge at night landscape?

in the first place, reduce the amount of street lamps, lower density. For there must be some street lighting, can proper widening street lamp installation space, in order to reduce the street lamp installation density and the total number. Approach is gradually widening installation space, form the street lights to the transition of the bridge street.

second, reduce the height of the installation of lamps and lanterns. More energy consumption, high street lamp lighting efficiency is lower, and its the glare could destroy the whole lighting effect. During the day, high street lamp lighting can also affect the bridge landscape effect.

play footlights, LED by adopting methods such as, the lights directly projected on the pavement, not only can improve the efficiency of lighting, also can avoid the influence on the driver line of sight. Right amount using dot LED, draw the road line, can not only for the driver to form the warning role, improves security, and lighting arrays are added to the road landscape effect.

the above method not only reduced the street light effects on the landscape, also ensure the driving safety, reduce the difficulty of installation and maintenance, reduce the lamps and lanterns of lamps and lanterns and adopts low power can also reduce power consumption, lower operating costs.

the second myth, dynamic lighting effects of abuse, cause light pollution.

with the rapid development of LED lighting, we have entered the era of dynamic lighting. In bridge lighting, also USES a large amount of dynamic lighting, make the bridge lighting more sporty and sense of science and technology.

but we should not ignore is that relative to the traffic on the river under the bridge, the bridge, stream of people, the bridge itself is an absolutely static landscape. Under the water sparkling, reflection, the deck on the traffic and pedestrian flow, its perspective is in itself a moving body, and on the basis of this, if again as a bridge lighting gives frequent changes of dynamic effect, can make the whole lighting effect of the bridge is dazzling, serious and even produce light pollution.

so, to be cautious with the bridge lighting dynamic lighting effects, instant use also as far as possible choose change cycle is long, slow the effect of the change process, let near to feel comfortable, make far more sense of looking forward to the viewer.

myth # 3, the color is too much, cause eyestrain.

LED lighting light colors have more options, make lighting are more diversified. Bridge also like commercial building lighting, lighting gradually adopt this new technology.

but the bridge is not a commercial space, usually is main style with concise, lively, grand bridge, subject to such structure with colourful business atmosphere, more or less.

no more ignore the Bridges in the environment, is often a river, the river or the mountains, the climate background brightness is low, usually so bridge lighting can easily stand out, if the illumination brightness and colour too, is very easy to form too strong contrast.

bridge lighting design should be treated as a work of art, colour is gorgeous, contracted and the atmosphere more beautiful. Colorful lighting is can give a person a feeling of content, novelty, but were also more likely to cause visual fatigue, with the passage of time, gradually into the aesthetic fatigue, thus fell into the pulp cycle.

to sum up, the bridge is the important element of urban nightscape lighting, it is important to urban public space, in order to create works of art, create comfortable, beautiful, reasonable bridge lighting design scheme, is the common goal of our lighting designer.
