How to avoid cost traps when purchasing LED light pole screens?
Recent data from a smart city project shows that 38% of budget overruns are due to errors in accessory selection. Core cost components include:
How to make a list of materials without getting into trouble?
Three types of certification qualifications are required:
Is online purchasing really reliable?
Compare the risk index of the two procurement channels:
| Evaluation item | Offline channels | online channels |
|---|---|---|
| technology suitability | 92 points | 68 points |
| Delivery on time rate | 85% | 73% |
| After-sales response speed | Within 24 hours | 72 hours |
| It is recommended to ask the supplier to provideReal installation case video, especially to check the actual display effect at night, which is crucial for judging the brightness uniformity. |
How to optimize the installation process to save worry?
The acceptance data of the smart street light project shows that projects using prefabricated structures:
In a smart park in a coastal city, engineers found that the surface temperature difference of light pole screens using active cooling systems in a 35°C environment was 8.2°C lower than passive cooling products. This difference in details directly affects the 12% failure rate fluctuation of the equipment during the rainy season. When selecting equipment, you may wish to touch the heating area of the prototype with the back of your hand. After 4 hours of continuous operation, the temperature should not exceed 45°C. This is a crude way to judge the quality of the cooling system, but it is more intuitive and reliable than the parameter table.
