Existing Lighting Challenges

Before Upgrade

The original municipal lighting system faced several common issues:

1. High Energy Consumption

Traditional street lighting consumed excessive electricity due to lower optical efficiency and outdated technology.

2. Uneven Road Illumination

Existing fixtures created:

  • Dark areas between poles
  • Poor uniformity
  • Reduced pedestrian visibility

3. High Maintenance Cost

Frequent lamp replacement increased:

  • Labor expenses
  • Traffic interruption
  • Municipal maintenance workload
