Signify Illuminates ‘Imperial City’ of Huế

Signify reported that Vietnam’s most important historical and cultural monument, the ‘Imperial City’ of Huế  has been illuminated with Philips Color Kinetics technology from Signify. (The city coincidentally has a similar name to that of Philips’ popular smart bulb Hue.) The thick stone walls of Huế fortress provided protection to citizens of the ‘Imperial City’ for almost a century and a half. Construction on the site began over 200 years ago after Nguyễn Ánh took over Vietnam and declared himself Emperor Gia Long in June 1789. China recognized his rule in 1804.

Gia Long consulted with geomancers to decide upon the best location to build a new palace and citadel. The geomancers picked a site in Huế. Building began in 1804. Gia Long ordered thousands of workers to construct a wall and moat, 10 kilometers wide. At first, the walls were made of earth, but later these earthen walls replaced with 2-meter-thick stone walls. The emperor then constructed a second set of tall walls and a second moat around his palace. Subsequently, he added many more palaces and gates and gardens, and courtyards.

Signify reported that Imperial City, which was once only accessible to royalty, has been revitalized with the latest LED lighting technology. The City of Huế intends for the new illumination of the monument to preserve and honor its history and create a special attraction at night for locals and tourists.

Deep purples, bright pinks, and vivid greens illuminate the walls and the ‘Flag Tower’, which is visible from miles away along the Perfume River. The new lighting can also create dramatic light shows that include simulating the firing of ‘cannons’ set in the walls of the tower. Signify anticipates that the LED lighting system will be up to 75% more energy efficient than conventional lighting systems.

Signify worked closely with Vietravel Company, which commissioned the project. The Chairman of Thua Thien-Hue provincial People’s Committee also sponsored the revitalizing lighting project. The lighting installation was completed in March 2018
The installation features 270 Philips Color Kinetics Vaya linear RGB LP and 155 Philips Color Kinetics Vaya Flood RGB LP controlled via LSM gen5 1000.

Other Vietnam landmarks lit by Signify include the Dragon Bridge in Da Nang, the Ha Long Bridge in Bai Chay, as well as the Hang Dau Bridge and Nhat Tan Bridges in Hanoi.

As of May 16, 2018, Signify became the new company name of Philips Lighting.
