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

The HLMP2400 is a highly versatile and commercially available LED light unit designed for general lighting applications. It can be used for general lighting such as in a factory, but it is especially valuable for circuit board indicators, arrays, light bars, and bar graphs. This article will outline the applications of these LED lights and the working principle behind them.

Applications of LED Lights

LED lights are increasingly popular as they are significantly more efficient than other forms of lighting. LED lights also offer a variety of applications. While they are often used as general lighting in a household, they are also useful in many commercial and industrial sectors. For instance, they are frequently used to indicate the status of an electrical circuit such as circuit board indicators, or as part of an alarm system. They can also be used to indicate the level of fluid in a machine. As such, LEDs can be used for many markets, including automotive, consumer electronics, industrial, signage, and aviation.

LED lights also have applications in decorative lighting, such as holiday and party decorations, as well as in art works and architectural displays. In addition, LEDs are widely used for the backlight for LCD display and for text message displays. Furthermore, LEDs are increasingly being used for indoor and outdoor display and sign applications, including billboards, awnings, corporate logos and signs, and menus in restaurants.

Working Principle of LEDs

LEDs are illuminated by the application of direct current (DC) power, using the principle of electroluminescence. When voltage is applied to the LED, electrons in the p-n junction structure of the LED move around in a way called electron-hole injection. This creates electron-hole pairs, and the electrons combine with the holes to produce photon emissions. The light emitted depends on the type of junction material used in the LED.

When low voltage is applied, the LED emits infrared light, which may not be visible to the human eye. As higher voltage is applied, the LED will produce visible light of different colors. For example, the HLMP2400 LED is available in various wavelengths, ranging from 275nm to 470nm, and is used for applications such as red, orange, yellow, green, and blue circuits.

Conclusion

The HLMP2400 is a versatile, commercially available LED light unit designed for many general lighting and circuit board indicator applications. It is used extensively in commercial and industrial sectors, as well as in decorative lighting and display applications. The LEDs are illuminated through the application of DC power and produce infrared and visible light depending on voltage.
