What are LED backlit signs?
LED backlit signs are custom metal letters and logos lit from behind by LED. Each separate piece has its own light source and its own circuit, made as a hollow, three-dimensional metal sign shell (called a channel in the U.S.) closed with an opal acrylic back-panel, rather than cut from solid metal. The light leaves through the back-panel and washes across the wall, so the halo traces the shape and the sign seems to float off the wall. In the sign trade the same product goes by halo-lit signs, reverse-lit signs, or backlit channel letters, and many buyers simply ask for a sign with backlight. The same build makes LED backlit logo signs, LED backlit letters, and, with deeper returns (the side walls of each letter), 3D LED backlit signs.
A complete LED backlit sign is generally made up of the following parts:
- Metal sign shell: A hollow metal sign shell fabricated from 304 stainless steel by default, marine-grade 316 stainless steel for coastal outdoor sites, and aluminum on large backlit signs to cut weight. See backlit metal signs for the two metals side by side.
- LED light source: The sign is lit by LED. Depending on the project we use LED modules, LED strips, or LEDs on custom circuit boards (PCB) to suit your custom sign, running on a safe 12V DC supply by default, with a bright output and an LED rated for over 100,000 hours.
- Acrylic back-panel: The acrylic back-panel closes the metal sign shell and works as the light-transmitting layer, letting the LED light spread evenly from inside the metal sign shell to avoid visible LED hot spots, for a cleaner, more even look.
- Wiring and power: Each separate piece comes with about 78-3/4 in (2,000 mm) of UL-certified flame-retardant two-core copper wire, one lead for 12V DC positive and one for negative. By default we use a quality Mean Well power supply to give the whole backlit sign stable power.
- Mounting: The sign mounts to the wall with stud bolts by default. If it needs to sit off the wall, we also provide stainless steel tube spacers to hide the studs and wiring and to set the off-wall distance.
