With the continuous advancement of LED lighting technology, its energy-saving advantages have become increasingly prominent, making it the preferred choice in the field of outdoor advertising light boxes and contributing significantly to the building of a green, low-carbon and environmentally friendly society. Today, LED bead advertising light boxes have been widely adopted in major commercial plazas, metro stations and bus stops. By contrast, traditional older advertising light boxes are prone to various failures once they reach the end of their service life, damaging the city's appearance and posing safety risks to the surrounding public. Advertising light boxes must therefore never be kept in service beyond their service life. The main reasons are as follows:

1. Overdue and Dilapidated Light Boxes Damage the City's Image

      Advertising light boxes are meant to beautify the urban environment and showcase the city's character. However, damaged and outdated light boxes on the streets not only lose their promotional value, but also undermine the city's overall appearance.

2. Overdue and Damaged Light Boxes Pose Safety Hazards

      In severe weather such as rain, snow, high winds or extreme cold, outdated light boxes still in service are prone to electric leakage, short circuits and power failures, and may even suffer component detachment or structural collapse. This is especially true for light boxes suspended at height, which must be replaced promptly once aging or damage occurs.

      Upgrading traditional fluorescent-tube light boxes to LED lighting has been tested by national-level professional testing institutions: light box brightness increases by approximately 125% compared with before the upgrade, and illumination uniformity improves by approximately 50%. Higher brightness and greater uniformity make advertising images clearer and more transparent, with soft light and vivid colors that strengthen the visual impact of the advertisement. Colorful LED advertising light boxes also adorn metro stations, offering passengers a better visual experience during their journeys.

      Beyond the upgrade in visual performance, the core value of the retrofit lies in energy conservation and consumption reduction. After the upgrade, the energy saving rate of the light boxes can reach around 70%, with a substantial drop in power consumption and remarkable energy-saving results. Putting the concept of “energy conservation and emissions reduction, with the metro taking the lead” into practice, the energy-saving retrofit of advertising light boxes helps deliver a genuinely low-carbon, green metro.

      Combining visual appeal with environmental protection, the energy-saving retrofit of advertising light boxes contributes to building a beautiful and green metro.
