LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar GraphsLight Emitting Diodes (LEDs) are small light sources that can be used to indicate the state of a circuit. The majority of LEDs available today use a semiconductor-based system to convert electrical energy into a light energy. The LED is a popular choice for lighting applications as they are low cost, require very little power, and are incredibly reliable.LEDs are typically used for indicators on circuit boards to provide a visual indication that a circuit is powered, or that it is in some particular state. The indicator lights can consist of single LEDs mounted on a board or array of LEDs in different configurations, from small sequences of three in line to large arrays of rows and columns of LEDs. Depending on their configuration, the lit LEDs can be used to show the status of a number of different parameters, such as temperature, pressure, or voltage.Light bars are LED arrays that are used as an alternative to single LEDs. A light bar can display patterns of light to indicate the state of different circuits or to provide a general indication of overall system status. Commonly used in automotive, home and medical applications, light bars are typically static and are used to show a fixed set of lights that indicate a particular condition.Bar graphs are another type of LED array commonly used in applications where more information needs to be displayed than a single light or a lightbar can provide. Typically composed of ten to fifteen rows of LEDs, the lights are laid out in a rectangular pattern and each row can be programmed to display a range of different levels of brightness, which can then be used to indicate the value of a parameter being monitored or of a specific status.In summary, LEDs are a reliable and versatile way to visually indicate the status of a circuit. Single LEDs, arrays of LEDs, light bars, and bar graphs are all used to display information such as temperatures, voltages, or the status of an individual circuit. Their low power consumption and cost make LEDs an attractive choice for designers, and their long operational life ensures that these indicators will continue to provide accurate information throughout the life of the circuit.
