LEDs (Light Emitting Diode) have been around since the early 1960s and are an essential component of numerous applications. They can be used to give visual display of information, and are found in a variety of lighting fixtures, display boards, and other items. The 5690113300 application field and working principles of LEDs is a very important topic, as this type is increasingly more popular.

Circuit Board Indicators

LEDs are frequently used as status indicators on circuit boards. In such applications the LEDs are used in the same manner as traditional lamps and to replace indicator lights. LEDs require fewer components in a circuit board than a standard indicator light. This makes them far more cost effective, as well as reducing the overall size and complexity of the circuit board.

LEDs used as indicators are typically bi-colour (two coloured) or tri-colour (three coloured). This allows the user to determine the status of an object or system at a glance. When configured correctly they can indicate a range of information, from indicating signal levels, indicating power output or indicating problems.

Arrays

LEDs are often used in arrays. An array is a series of LEDs placed together in a single line, a curved line, a circle or a variety of other shapes. This is often done for aesthetics reasons, as the shaped array will appear more eye-catching than a collection of individual LEDs. An array may also be used to produce a particular effect, such as an advancing line of light or an expanding ring.

LED arrays are also used to create large scale displays. By using multiple arrays together a display can be produced which is visible from a greater distance than a single LED. Such displays can be used for advertising space, events, or other large scale applications.

Light Bars

Light bars are devices consisting of a line of LEDs running along a straight line. These devices are used to backlight advertising signs, displays, signs or to indicate a path or direction in a dark environment. They can also be used to create a “night light” effect in a room when connected to a timer or motion sensor.

Bar Graphs

Bar graphs are used to display data in a highly visual way. LEDs are often used for these purposes, as the bright intensity of LEDs means that information can be clearly seen from far away. Such displays may be used for temperature, humidity and pressure readings, stock market data, or in fact any other numerical data which needs to be portrayed in this way.

LEDs are also commonly used in audio systems, such as those found in vehicles. LEDs are used to indicate volume and other settings, mainly for decorative purposes. LEDs can also be used in television sets, CD players and other audio systems to indicate modes and setting.

The 5690113300 application field and working principle are broad and varied as LEDs can be used in countless situations in modern technology. From simple indicator lights to whole display systems, LEDs are an essential part of the modern world.
