Power supply failure is one of the most common long-term problems in LED displays.
وهذا صحيح بشكل خاص لـ:
- اللوحات الإعلانية الخارجية
- high-brightness systems
- long-hour operation environments
- high-temperature regions
Why Power Supplies Fail
Power supply aging may accelerate because of:
- ارتفاع درجة الحرارة
- unstable voltage
- moisture
- سوء التهوية
- 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.
ويصبح هذا الأمر بالغ الأهمية بشكل خاص في:
- مشاريع الشرق الأوسط
- المناخات الاستوائية
- الهياكل المغلقة
Poor ventilation is often a bigger long-term risk than direct rain exposure.
ملاحظات مهندس 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.
