LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs: 5350T7LC Application Field and Working Principle

Light emitting diodes (LEDs) are a type of electronic component made of semiconductor material. They feature a negative (N) terminal, a positive (P) terminal and a small internal gap between them containing a special material called a p-n junction. When activated, the p-n junction produces an excited state at which the electrons and holes recombine radiation in the form of visible light. LEDs are widely used in a variety of applications, such as indicator lamps, displays, warning lamps and for lighting. The 5350T7LC is a high-performance LED developed by Osram, which can be integrated into a circuit board and used to indicate electrical signals and measurements within a system. This article focuses on the application field and working principle of the 5350T7LC.

Application Field

The 5350T7LC is a 2-color LED that is specifically designed for applications requiring a dual indication of process changes. This includes DC voltage monitoring, motor speed indication and pressure measurement. Additionally, this device can be used in numerous other applications such as in automotive and industrial switches, control systems, and audio or video displays.

Working Principle

The 5350T7LC LED is composed of two discrete semiconductors. The first one is a red LED and the second is a green LED. The red LED is activated by applying a voltage greater than 2.7V across the LED terminals. The green LED is activated by applying a voltage greater than 3.5V across its terminals. Thus when a voltage greater than 2.7V and less than 3.5V is applied, both LEDs are imparted with a correct amount of current, resulting in the combination of red and green colors.The emission of light from this device is based on two separate recombination processes that occur at different p-n junctions in the device. In the first process, an electron-hole pair is generated at the first p-n junction when the device is connected to an AC power supply. This electron-hole pair is moved by an external electric field to the second p-n junction. At this junction, the electron-hole pair recombines and emits a photon of light. The second recombination process occurs between the two different semiconductors, where electrons from the red LED recombine with holes from the green LED and result in the emission of two photons of light. The emission of two photons of light gives the LED its two-color output.

Conclusion

The 5350T7LC LED is a versatile device that can be used in a variety of applications requiring dual indication of process changes. It is composed of two different p-n junctions that recombine when a voltage greater than 2.7V and less than 3.5V is applied. This device employs two separate recombination processes, which produce two photons of light, resulting in the two-color output of red and green. Therefore, the 5350T7LC LED is ideal for applications requiring a compact multi-colored output.
