LEDs, or Light-Emitting Diodes, are among the most widely used types of circuit board indicators. They are available in a variety of shapes, sizes, and colors; have low power requirements; and provide a range of performance options. Among the numerous applications are backlighting, display indicators, status signals, and architectural lighting.The most common type of LEDs are the surface mount (SMT) types, which provide a low profile solution with minimal board space requirements. These are available in a variety of sizes, ranging from 0603 to 3810. Furthermore, specialist LEDs are available for medical and military applications.The wide variety of LEDs also extends to their operation. Single color, multiple color, and white-balance LEDs are available, each with its own peculiarities. Single-color LEDs are usually simply on or off, used for power and mode indication. Multiple color LEDs can display multiple colours but require external control to do so, such as current sources and multiple PWM controllers. White-balance LEDs are usually capable of variable brightness, allowing for a wide range of performance options.Another type of LED is the array, which is a series of individual LEDs mounted in a single housing. These are often used in robotics and control panels, primarily because they can be laid out in any shape or form, and they are easy to read and define. The most common type of LED arrays are LED bar graphs and LED light bars, which can be used to display numerical values or progress bars, respectively.Finally, there are the specialty LEDs, which are not always used on circuit boards. These include super-flux LEDs, which have a wide beam angle and intense light output, making them suitable for special applications such as automotive lighting, backlighting, and status signals. Other examples are rectangular LEDs and dot-matrix LEDs, which are used in advertising displays and LCD panels, respectively.In summary, LEDs are among the most versatile types of circuit board indicators, providing myriad performance options and suitable for a wide variety of applications. Single color and multiple color LEDs are ideal for power and mode indication, while white balance LEDs can be used for variable brightness control. LED arrays are widely used in robotics and control panels, and specialty LEDs such as super-flux LEDs can be used for automotive lighting, backlighting, and other signage applications.
