Using generic software, when modules need to be repositioned to achieve optimal, uniform illumination—or added to or removed from the layout—it is a manual, individual task. Each module needs to be moved, added or removed before other modules are adjusted to maintain proper spacing. There is no way to select multiple modules at the same time.

Similarly, generic design software can be used to import a power supply as an ‘object’ and position it in the layout, with a rectangular or polygonal selection of modules connected to it. This involves manually counting all of the modules to include with that power supply, however, as well as adding the wattages of each module to ensure they do not exceed the supply’s capacity. This can be time-consuming and error-prone, especially when planning large channel letters and/or sign cabinets.

For these and other reasons, generic design software is only a limited option for laying out LED designs. Sign-specific design and layout tools, on the other hand, are a logical choice. They can create vector paths for LEDs, each evenly populated with modules, with a priority placed on the corners.

As LED-based signage has become more popular, the industry has seen the emergence of LED-specific sign design software, with new tools that streamline the process for creating complete LED layouts, including modules and power supplies. Automatic layout routines and editing tools support a wide range of channel letter fonts and sizes.

Winning in the market
As more channel letters and sign cabinets are lit with LEDs, rather than with traditional neon or fluorescent technology, it is safe to say they have largely ‘won’ in the market. So, while the process of generating layouts of LEDs necessarily started out with their suppliers, it only makes sense that electrical sign companies have brought these tasks in-house over time, for reasons of control and quick turnaround.
