The buildings on the People's Street, such as the Jilin Provincial Party Committee, the Provincial Government, the People's Bank of China Jilin Branch, the City Netcom Company, the Municipal Public Security Bureau, and the Jilin Province Hotel, are a unique landscape on the People's Street. It mainly uses point light source or linear LED light belt to display the outer contour of the building. It uses local floodlighting to highlight details and enhance the effect of three-dimensional space, adding rhythm to the composition of the whole street.
The modern-style architecture of People’s Street pursues the cooperation of architectural form and internal functions. For each building's different shapes, we use different lighting techniques to light its features. Small and medium-sized buildings, such as Datang Power, Northeast Electric Power Design Institute, Jilin Expressway, etc., use floodlighting to render the whole facade while using low-power special lights or LED modeling lights in the area between the panes. Projecting a little mottled on the top, it is ingenious. For large-scale high-rise buildings, such as Jilin Water Conservancy Building, Provincial Publishing Bureau, Bauhinia Hotel, Weifeng International, Xinji Grain Building, etc., the design of point, line and disc LED arrays is arranged on the façade, according to the building function Different digital transformation programs, the top of the building, especially the extraordinary and unique details of the façade, with eye-catching floodlights and soft interior lighting, in order to show the magnificent temperament of the building, to achieve the "finishing the finishing touch, lead the way The effect of the global".
Renmin Street is known as the “Green Corridor†because of the lush trees on both sides. It is the symbol of “Forest City†and “Eco-City†in Changchun City. It is also the most distinctive lighting and color carrier for night landscape lighting. We designed a set of “Urban Light†landscape lights every 20 meters on the pedestrian walkway, using a warm white light source; under the main color of warm yellow street lights, a line of beads, giving people a light, elegant feeling. In the "City Light" landscape light, the green light is used to illuminate the trees, and the trees are color-adorned with high-tech new lighting products such as digitally-changing LED lights and snow-shaped LEDs. The heavy, dark image uses the art of light language to express its inner beauty.
A bird's eye view of the People's Street, the "yellow, green, white" colored light belt perfectly shows its elegant posture, and the architectural lighting around the road reflects each other, highlighting a flowery and magnificent urban style, reflecting a thriving , a harmonious urban spirit.
Second, the South Lake water system landscape group
The water body is the most natural natural factor in the composition of the city's night scene. The light and ripples of water are the visual and imaginative landscapes of the city's night scenes. The night scenery of the Nanhu water system is to use the river water system as the landscape carrier, to reflect the cultural characteristics of the city, to improve and beautify the night image around the South Lake, and to create a fresh and beautiful urban nighttime function and environmental landscape system.
Projecting the colorfully-changed lights onto the water curtain from the top down, the spectacular Nanhu Bridge is like a colorful rainbow across the water, giving the illusion of being separated from reality and fantasy. Floodlighting, and the reflection reflected on the water surface, the shape of the bridge is thick and stretched. The seagull-type LED on the railing is chasing and flashing, which injects new vitality into the whole bridge.
