Firstly, bridge lighting mainly refers to the lighting of the main body of the bridge.
The main body of a bridge is the soul of the bridge and must be represented by light. The biggest feature of the bridge deck is its sharp contrast with the railing above and the bridge opening below, which is the goal of the entire bridge facade lighting design. There are many lighting methods for the side walls of bridges, and there are basically two commonly used ones: one is floodlighting, which can fully display the entire side wall of the bridge by the light, making it spectacular from a distance; Another way is to use the side wall of the bridge to install light emitting elements. When using floodlighting schemes, the power consumption is high, and the lighting fixtures are in a very obvious position during the day, resulting in poor aesthetics; At night, the entire bridge is illuminated without any omissions, lacking a sense of hierarchy and expressiveness.
The second is the lighting of bridge guardrails.
Guardrail is usually a place that requires lighting rendering to showcase the style of the entire overpass. There are two ways to brighten the guardrail: one is to use continuous RGBW led linear lights to outline the guardrail, which can be expressed in various forms: for example, single or alternating colors can be used, or computer controllers can be used to achieve various forms of flowing colors such as fixed flashing, random flashing, gradual alternating flashing, chasing, etc., making the entire bridge area full of vitality. Another method is to install led point lights at regular intervals, which can outline the guardrail and give a lively feeling.
Thirdly, the lighting of bridge columns.
The columns of overpasses are an indispensable part of lighting landscape design. Generally, floodlights - metal halide light sources are used to depict the nighttime characteristics of columns, showcasing the grandeur, strength, and distinctive features of bridges. Metal-halide lamp is a good light source for large area floodlighting. Due to its good color rendering and high color temperature, adding various filters to its light source can achieve ideal colors.
The above is the key points for bridge lighting, hoping to be helpful to everyone. In fact, when lighting bridges, in order to highlight the layering and beauty of the lights, we can display the characteristics of the bridge by rendering the light of the bridge guardrail, bridge body, bridge columns, etc., instead of lighting all the bridge components of the same overpass, making the entire bridge shine.
