LED displays or LED floodlights are recommended for exterior wall illumination advertising. The specific choice depends on the budget and installation environment.
1. LED Display Screens: Suitable for dynamic advertising, offering high resolution and vibrant colors. Small-pitch LED screens (P2.5-P4) are suitable for close-range viewing, while standard pitch (P6-P10) is suitable for long-distance displays. Note that a waterproof rating of IP65 or higher is required, and a brightness of 5000 cd/m² or higher is recommended to cope with strong daylight.
2. LED Floodlights: Lower cost, suitable for static pattern or text projection. High-power RGBW mixed-light fixtures (100W or higher) can achieve color changes, and dynamic effects can be programmed using a DMX512 control system. The projection angle and distance need to be calculated during installation to avoid light pollution.
3. Other Alternative Solutions: Laser projectors are suitable for temporary events, but are greatly affected by ambient light; neon tubes are suitable for retro styles, but have high energy consumption and complex maintenance. For high-rise buildings, lightweight LED modules with wind-resistant design should be prioritized, and fragile glass tube-type light fixtures should be avoided.
