The Complete Guide to Fiber Optic Backlighting
Backlighting is a common feature in many devices. Keypads and switches, for instance, often feature backlighting. It's able to illuminate the interface buttons on keypads and switches so that they are easier to see. There are different types of backlighting, though, one of which is fiber optic. For a better understanding of fiber optic backlighting, keep reading.
What Is Fiber Optic Backlighting?
Fiber optic backlighting is a lighting solution that leverages glass or plastic fibers. These fibers are ultra thin, with many of them measuring about the same diameter as a strand of human hair. Fiber optic backlighting consists of bundles of these ultra-thin strands.
Whether made of glass or plastic, the strands used in fiber optic backlighting are transparent. Transparency, of course, allows light to shine through them. This is essentially how fiber optic backlighting works. It doesn't necessarily produce light. Rather, fiber optic backlighting distributes light across the keyword or switch with which it's used.
How Fiber Optic Backlighting Works
As previously mentioned, fiber optic backlighting doesn't produce light. It's designed to distribute light. Most fiber optic backlighting systems work in conjunction with light-emitting diodes (LEDs). The LEDs produce light that travels through the fiber optic backlighting before ultimately reaching the keypad's or switch's buttons.
