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

Light emitting diodes (LEDs) are widely used in today\'s technology, from commercial signs to circuit board indicators in consumer products. LED technology has progressed significantly with the development of the LED array, or the LED chip, which contains multiple LED elements. LED lights are highly sought after for their bright light source and longevity. LED arrays are often used in various applications to indicate or control various signals or operations.

LED Circuit Board Indicators

LEDs are primarily used as indicators on circuit boards and are also widely used in automotive, industrial, aerospace, and medical applications. These types of circuit board indicators are commonly used in situations where a low-cost, low-power option is desired. LEDs generally operate at lower voltages than their counterparts, incandescent bulbs, and can last for thousands of hours when used correctly. The color of the LEDs can be changed to indicate different pieces of data or parameters, such as a green LED to show a power on indicator or a red LED to show a fault. LEDs are also used as displays in consumer electronics.

LED Arrays

LED arrays consist of multiple LED elements integrated onto a single chip. This type of LED has several advantages over traditional LED components; typically, LED arrays are brighter, longer-lasting, and more reliable than the individual LED elements. The LED array typically contains an integrated circuit (IC) which controls the individual LED elements, allowing for greater control over the light output. LED arrays are often used in indicator displays, traffic lights, and accent lighting.

Light Bars and Bar Graphs

Light bars and bar graphs are two popular applications for LEDs. Light bars are often used as indicator or warning lights, or are used to display specific pieces of data in the form of a chart or graph. For example, a light bar may be used to indicate the current level of a process variable, such as temperature or pressure. Bar graphs are also used in a similar fashion, but often require the use of multiple LED elements arranged in a specific pattern to create the desired effect.

Conclusion

LEDs have become an integral component of today’s technology, from circuit board indicators to traffic lights and bar graphs. LEDs are highly sought after for their bright light source and longevity, and are also more economical and efficient than other lighting solutions. LED technology has progressed significantly with the development of the LED array, or the LED chip, which contains multiple LED elements. These types of LEDs can be used in a variety of applications, making them a popular choice for component and system designers.
