Lighting Renovation of Tianjin Joy City

Tianjin Joy City, as a commercial landmark that has been completed for nearly 14 years, holds an important place in the mind of the citizens. However, the curtain wall has gradually aged with the passage of time while the lighting fixtures suffered varying degrees of damage. As a result, the Joy City has also lost its former charm at night. This renovation project, centered on lighting design, aims to breathe new life into the building while aligning with urban renewal, energy efficiency, environmental sustainability, and modern aesthetics.



This renovation maximizes the principle of "making the best use of existing resources" by fully utilizing the existing pipelines, control systems, and lighting positions. The overall visual effect is significantly enhanced by simply replacing the lighting fixtures. In the case of the "Chinese Rose" glass structure had lost its brilliance due to the damage of the original lighting fixtures. By means of replacing them with specially designed light distribution and constant power luminaires, three sides of the structure frame can be effectively illuminated. which significantly reduces energy consumption. The lighting fixtures that illuminate the structure of the "Chinese Rose" are coordinated with the dot lighting, presenting various dynamic effects through programming.



• Daily Mode: The lighting gently fades from top to bottom, resembling the layered blossoming of petals. The flickering effect of the dot lights is like raindrops on the petals, adding a sense of liveliness and vitality to the overall dynamic lighting

• Festive Mode: Lighting effects change with the city’s moods during celebrations or rainy days. The dynamic lighting effects are sometimes as lively as bubbles rising and at other times as elegant as the aurora spreading, infusing the building with a diverse range of visual expressions.



This renovation project not only revitalized the architecture but also rekindled residents’ precious memories of this landmark, which demonstrates the unique charm of coexistence with the city.
