Artistic lighting on the Cable-Stayed Bridge over Hieu River

The cable-stayed bridge across Hieu River - the project connecting the North Hieu River Urban Area with the center of Dong Ha City - is an artistic highlight that highlights the urban river landscape. Visitors to this cable-stayed bridge space will experience the lighting art of emotions between light and architectural space.

Lighting can add emotional value to architecture, helping to create a spatial experience for people, drawing attention to the structure, color and form of a space. Vision is the most important means through which we enjoy architecture, lighting helps us perceive architecture more clearly.

At night, when the sun sets, the architecture of the building is engulfed in darkness, and exterior lighting plays an important role in expressing the architectural form. This is especially important for buildings - especially those that act as focal points and have an orienting meaning in urban space.

There are three types of lighting. They are focal lighting, ambient lighting and highlight lighting. Focal lighting is called task lighting, which highlights important elements and draws attention to areas. Ambient lighting (also known as general or ambient lighting) is background lighting that illuminates the entire space, leaving no shadows so that people feel safe, creating a sense of freedom and limitlessness in space. Highlight lighting (also known as accent lighting) is a type of lighting that is variable and colorful, stimulating human emotions. The cable-stayed bridge across the Hieu River uses this type of lighting. Highlight lighting stimulates the optic nerves, arouses curiosity and attracts and captivates viewers.

The lighting solution for the cable-stayed bridge over Hieu River not only simply illuminates the project but also cares about the surrounding landscape, harmonizing colors, contrasting brightness, layout, and shape, thereby clearly depicting the characteristics of the project in the general landscape.

The elements of lighting, light direction and light color on the modern cable-stayed bridge over Hieu River and the lighting effects of the project make the functional relationships clear.

Creative lighting elements help viewers to admire the building and bring a diverse, interesting and emotional scene. To do this, lighting must be based on the scale, nature and characteristics of the building.

Here, lighting is not simply installing lights but also satisfying requirements such as: highlighting the main view of the project, clarifying the limits of the project, depicting specific details such as patterns, decorative lotus symbols, cable-stayed bridges, arches, columns, reliefs...; at the same time creating contrasts of light and dark, color, and depth. The lighting system of the cable-stayed bridge across Hieu River is a lighting system that goes deep, stable, and sustainable. It creates an attractive, lively, and brilliant look for the bridge.

To make this project more effective, should we classify the scenario for the project with different lighting levels, divided into different times of the week and year to reduce monotony and avoid wasting energy?
