LED PCBs are specific types of printed circuit board, designed for use in a wide array of lighting modules and applications. A number of light emitting diodes (LEDs) are mounted to a PCB forming a completed circuit, allowing full control of their behaviour through various types of chips or switches.

Countless industries and applications rely on LED PCBs to control lighting arrays in multiple devices and setups. Common examples include:

• Automotive lighting

• Street and tunnel lighting

• Indicators and display panels used in telecoms devices and computing

• Torches, flashlights and work lamps

• Signal lighting

• Medical room and device lighting

LED PCBs have a number of distinct qualities and characteristics that make them especially well suited to these kinds of uses. Among the most important are:

• Economy – LED components are fairly cheap to buy, and very efficient to run

• Reliability and longevity

• Low power draw

• Low profile, lightweight

• Fairly resistant to the effects of dirt and moisture ingress

• Versatile – highly programmable, and sold in a diverse array of colours/sizes
