LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs

Light Emitting Diodes (LEDs) are semiconductor devices that are increasingly being used as reliable, efficient, and colorful indicators for circuit boards, arrays, light bars, and bar graphs. LEDs provide users with a visual indication that requires minimal power and are available in many shapes and sizes.LEDs are essentially one-way conduits for electricity. A LED chip is surrounded by a transparent, plastic indicator that allows the light from the LED to pass through, thus providing both visual and optical indicators of the LED\'s state. LED chips are built on a special type of semiconductor material that emits light when a current passes through it. When the LED is in the "on" state, an electrical current passes through the LED and electrons become “excited” and move to higher energy levels. As they move to higher energy levels, they release the energy in the form of light. Once the electrons return to the original energy level, the LEDs is "off" and there is no longer a current. LEDs are capable of providing high intensity lighting in a very compact space. This makes them well suited for a variety of applications. For circuit board applications, LEDs are used to indicate various states of the board, such as power on/off, data transfer, and alarm state. LEDs can also be used in arrays of individual LEDs to create light bars and bar graphs. The use of an array of LEDs allows an end user to keep track of a variety of conditions on a single display. LEDs have also become popular for use in automotive and aerospace applications. LEDs are capable of providing bright, easily visible lighting in these applications due to their efficient use of power and small form factor. Additionally, LEDs are well suited to these applications due to their robustness and reliability. LEDs can be used to display the condition of the vehicle or aircraft and serve as a visual warning indicator for low fuel, oil, or other critical states. The efficiency of LEDs make them ideal for use in portable electronics and other battery operated applications. Because LEDs require minimal current to operate, they provide an efficient way to extend battery life in handheld electronics such as medical devices, radios, and cell phones. Additionally, LEDs are more durable and resistant to shock, vibration, and other environmental conditions than other indicators such as incandescent lights. In addition to their visual indications and energy efficiency, LED indicators can also be programmed to display multiple colors. This feature makes LED indicators well suited for commercial applications, including traffic signals and warning signs. Additionally, some LED indicators are capable of being programmed to flash or change color to indicate different states. LEDs have become an essential component in the modern electronics industry. Their ability to provide visual indication in a small form factor, along with their powerful energy efficiency make them well suited for a wide variety of applications. LEDs have enabled engineers to create faster, smaller and more efficient devices without increasing power consumption. LEDs are ideal for automotive, aerospace, circuit board, portable electronic, and commercial applications and can enable users to access critical information or warnings in a convenient and efficient manner.
