Even if you're an indoor LED expert, outdoor LED displays introduce a new set of challenges and considerations. But don't fret! Our guide will help you navigate these outdoor beasts.
When it comes to technology, it's often said that necessity drives innovation. Similarly, the articles in this blog arise from a need to discuss and dissect pressing issues in the LED world. Today, we tackle a giant of a topic - outdoor LED displays, which have peculiarities that separate them from their indoor counterparts.
Peering into the Deep Waters
Think of an iceberg, with a vast portion hidden beneath the ocean surface. The same principle applies to outdoor LED displays. The core technology may be the same as indoor displays, but the differences are many, and not always visible at first glance. The aim of this post is to dive beneath the surface and bring those differences to light.
Besides application, viewer distance, and pixel pitch, two main factors come into play with outdoor displays. One is the display's resilience against harsh outdoor conditions, and the other involves installation intricacies.
Built to Withstand
Outdoor LED displays are designed to handle extreme weather - be it heavy rain, scorching sun, or dust storms. These displays have higher IP ratings, indicating their superior protection against environmental factors. In simple terms, while indoor displays are created to function in controlled environments, outdoor displays are engineered to battle nature's extremes.
Different Demands
Outdoor LED displays often rely on robust, older LED technologies like the Dual In-Line Package (DIP) due to its rugged design and luminous output. Indoor settings might need 800 to 2,000 nits of brightness, but outdoor displays in sunny locales may need 7,000 or more nits to maintain high-contrast visuals. Besides, outdoor LED displays have hardy cabinets and built-in fans and ventilation systems to keep them functional, even in soaring temperatures.
While the pixel density is typically lower for outdoor LEDs, thus reducing component costs, there are often additional costs associated with securing the display on a building or providing power for a highway screen. Plus, there's usually more paperwork involved in obtaining local permits and approvals.
Permits and Installation
Understanding the challenges of traditional outdoor signage installation requires insights from industry experts. It's clear that specifying and installing outdoor signs is vastly different from indoor signage.
Installations may require certifications that vary by state. Some states require a contractor's license to install electric signs, including LED displays. Code and building permits can differ from state to state, county to county, and even city to city.
Furthermore, power and service issues need careful consideration. The display's power requirements need to align with the available electrical service. Often, adding an LED display to an existing structure demands additional electrical service capacity, thus requiring a licensed electrician.
Overcoming the Challenges
While dealing with outdoor LED displays may seem overwhelming, having a clear understanding of the prerequisites can make all the difference. This guide is not meant to deter you, but rather to highlight potential stumbling blocks on the path to a successful installation.
In the realm of outdoor LED, accounting for environmental rigors, choosing the correct display, and understanding the necessary paperwork will determine your project's success. Get informed, get prepared, and conquer the world of outdoor LED displays!
