Overview
Indoor LED displays generate heat during prolonged operation, especially in summer when ambient temperatures are high. This article discusses whether indoor LED displays require dedicated cooling equipment.
Key points
-
Manufacturers typically use indoor-specific LEDs with brightness limits below 1200 cd, commonly set between 800 and 1000 cd. Users can adjust brightness to suit the indoor environment, so overall luminance is relatively moderate.
-
For indoor full-color screens, the supporting steel structure is usually mounted away from the wall, leaving a 5–10 cm ventilation gap to allow some heat to dissipate.
-
Indoor spaces that host LED displays generally use air conditioning during hot weather, which helps cool the display.
Conclusion and recommendations
In summary, additional cooling equipment is generally not required for indoor LED displays, and temperature typically does not have a major impact. Attention should be paid to waterproofing and protection against physical impact. If indoor humidity is very high, inform the display manufacturer during customization so they can coat the PCB to reduce moisture ingress and prevent module corrosion.
