"Generally, power supplies follow LED design trends, not the other way around," Picot points out. "The excep- tion is that loading on class II power supplies is much higher when using 24V LEDs, which is why the industry is shifting toward 24V systems." All added, high-func- tioning LEDs and power supplies have increased the life of an LED sign, causing less headaches and more functionality. "Useable lifespan in terms of lumen mainte- nance and color consistency has increased, meaning the sign doesn't need to be refreshed as often," says Picot, "but several of our customers have Tetra LED systems that have been operating for well over 10 years." Focused on the Future To look ahead several decades, one must look behind as well. Understanding what sort of problems technology was able to fix in the past will give sign professionals an idea of what might be on the horizon. For instance, matching color accuracy and finding the appropriate level of bright- ness have always been two relevant challenges in the lighted sign industry. "In the next 10 years, as technologies continue to improve, we will see new and better sign lighting products enter the market," predicts Riley. "The benefits will be even greater energy savings, even closer consistencies, and more options for challenging sign applications." Ease-of-use for both sign makers and end users continue to be a highly sought-after perk. Installation issues can become hurdles for sign makers and misunderstanding how to manage or maintain signage can plague users. "Recent market trends indicate a continuing demand for greater flexibility in LED products, meaning ever-shrinking module sizes, as well as increased efficiency in response to growing concerns about energy consumption," shares Picot. Salitrero adds, "I see resolutions getting higher and higher, along with a more plug-and-play ready product for our sign company partners. Allowing them to install an LED display with minimal experience." Whatever new features are brought to the market, it's safe to forecast that LEDs are here to stay. And, most likely, will continue to grow as new technologies form. "LEDs will continue to be the dominant source of lighting in signage over the next 10 years," Vincent says. "As lifetime and efficiencies of LEDs reach their ceiling, benefits to sign makers will centrally revolve around novel systems that save installation and manufacturing times." SDG Recent market trends indicate a continuing demand for greater flexibility in LED products, meaning ever- shrinking module sizes, as well as increased efficiency in response to growing concerns about energy consumption.
