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

Light emitting diodes or LEDs are popularly used as circuit board indicators as they require only low power while producing bright light. LEDs are available in various sizes, shapes, and colors. Among these types, the QBL7YG80D-MP4A LED module is one of the most sought after.

QBL7YG80D-MP4A Application Field

The QBL7YG80D-MP4A is an indicator with 8 monochromatic LED elements in a 12 X 12 mm package. These diodes are generally preferred as, it requires only 3-6 volts to terminate. It is also commonly used in applications such as indicator light, control interface, alarm or so on. These eight colorful indicators are suitable for multiple occasions and hence they are popularly employed in smart next-generation circuit boards.

QBL7YG80D-MP4A Working Principle

The QBL7YG80D-MP4A series includes four basic models YG80D-MP4A, BI-YG80D-MP4A, RG-YG80D-MP4A, and WT-YG80D-MP4A, which represents light colors: yellow, blue, green, and white, respectively. The corresponding working voltage is 3V, 4V and 6V. Depending on the model, the LED module is with 8 pins, making it compatible for multiple circuit board applications.

The construction of the module includes GaAIAS (Gallium-Aluminum-Arsenide) that has a rectangular structure with a reflector and lens. The 8 wires are connected to each of the pins and can either be connected directly or through the process of soldering. The four layers of the device include the anode, active layer, reflective layer, cathode layers.

Upon the application of power, electrons rush towards the anode layer through the active layer and are reacted on the way. This reaction produces photons which are emitted in the form of light. Thus, photons which leave the module are reflected through the reflector while those that don’t reach the reflector pass out through the lens. This results in the lighting of the indicator module.

Generally, the expected life time of the module is about 10,000 hours and it has an operating temperature ranging from -25 degree centigrade to +85 degree centigrade.

Conclusion

The QBL7YG80D-MP4A is a widely used monochromatic LED module with a design of 8 elements. Depending on the color and working voltage, it is available in four types. The module functions by the release of photons on the application of power, which results in the emission of bright light. With a low power requirement and a long life, the module is widely used in indicators, alarms and control interfaces.
