• Maintenance

    Thinking for people, with our best, consistently


Maintenance type

  • Regular inspection: Installation conditions of the signs, illumination performance, solar cell power generation efficiency, precision inspection by each unit
  • On-time inspection: Check signs for abnormal operation, degradation or stoppage, and damage

Regular checkpoints

Conditions of signsExterior damage, contamination, variation of installation angle, pillar support
Illumination performance (nighttime) light emitting part illumination, brightness, chromaticity, uniformity, flickering, optical fiber holder elimination
Solar power generation efficiencyPower generation, installation angle variation, surface contamination, presence of surrounding sunlight shield
Precision check for each unitInternal wiring insulation and connection state, control box sealed state, battery performance
