Power supply failure is one of the most common long-term problems in LED displays.
C'est particulièrement vrai pour :
- panneaux publicitaires extérieurs
- high-brightness systems
- environnements de travail impliquant de longues heures
- high-temperature regions

Why Power Supplies Fail
Power supply aging may accelerate because of:
- surchauffe
- unstable voltage
- moisture
- mauvaise ventilation
- excessive brightness settings
Many outdoor projects underestimate long-term thermal pressure.
Why Heat Is Often the Real Problem
In many high-brightness outdoor installations, trapped heat inside cabinets gradually damages power systems over time.
Cela revêt une importance particulière dans les cas suivants :
- Projets au Moyen-Orient
- climats tropicaux
- structures fermées
Poor ventilation is often a bigger long-term risk than direct rain exposure.
Notes de l'ingénieur DDW
Many customers focus heavily on waterproofing while underestimating thermal management.
In reality, stable airflow and proper ventilation are among the most important factors affecting power supply lifespan.
