Replacing traditional lights with LED lights in buildings and streets saves up to 80% of energy.

Associate Professor, Dr. Nguyen Hong Tien, Chairman of the Vietnam Lighting Association, said that green lighting consists of three components: high-performance LED light sources, smart lighting control systems, and the use of clean energy sources. This model brings comprehensive benefits to the economy , the environment, and human health.

“In terms of economics, green lighting systems using LED lights only require about 10-20% of the electricity compared to traditional lighting equipment. The average lifespan of LED lights is from 30,000 to more than 50,000 hours, significantly reducing replacement and maintenance costs. In terms of the environment, LED lights contain almost no toxic substances, can be recycled and help reduce up to 1/3 of carbon emissions compared to many traditional lights. In addition, the long lifespan also contributes to saving materials by reducing the need for frequent replacement,” Associate Professor, Dr. Nguyen Hong Tien analyzed. He also said that optimizing lighting efficiency not only helps reduce costs but also improves the quality of life, while contributing to creating a harmonious and modern urban landscape.

In the context of urban areas moving towards green, smart and sustainable development, smart lighting systems play a key role in building modern cities. Many cities nationwide such as Hanoi , Ho Chi Minh City, Can Tho, Da Nang, etc. have implemented green lighting application projects with LED technology on many scales. Replacing traditional lights with LED lights in buildings and streets helps save up to 80% of energy. At the same time, the public lighting system is remotely controlled via IoT software, allowing programming of on/off times, adjusting light intensity and integrating many other smart functions.

In Hue , Hue Urban Environment and Construction Joint Stock Company (HEPCO) is the unit that manages and operates the lighting system in the city, with more than 478km of main streets lit, the lighting rate is 98% and 242km of alleys and lanes lit, the lighting rate is 65%. Hue is currently the city with the highest LED lighting rate in the country, with about 18,864 LED bulbs, accounting for about 68% of the total number of bulbs used in the city.

Mr. Hoang Van Tien, Director of the Lighting Electric Enterprise under HEPCO, shared that to control the large-scale lighting system, HEPCO operates a large-scale public lighting control and monitoring center, connected to 341 lighting cabinets, operated using GSM/GPRS/3G wireless communication technology. Therefore, the connection and control from the center to the cabinets throughout the city is almost instantaneous, allowing the lights to be turned on and off in accordance with the daily weather changes of the city. HEPCO is also in charge of the decorative lighting systems at Truong Tien Bridge, Ky Dai, and Dai Noi at night, creating more highlights and modernity for the city.

Efforts in developing green lighting have helped Hue save energy, reduce emissions and beautify the urban landscape at night. The city not only creates a green - clean - bright space, harmonizing modernity and identity, but also affirms its pioneering role in the trend of building sustainable urban areas, becoming a model worth referring to for many other localities.
