LED Indication - Discrete: LN85RP Application Field and Working Principle

Discrete LEDs are some of the most commonly used indication component across the world. They are simple, reliable, and low cost. The LN85RP is a discrete LED developed by Nichia Corporation to address the wide range of discrete LED applications. This article seeks to provide an overview of the LN85RP's application field and its working principle.

Application Field of the LN85RP

The LN85RP is a red-oriented, low-current rated discrete LED with a 2.1V maximum forward voltage. This component finds its most common applications in automotive lighting as a point source of light and as a light source in indicator panels. Because of its low-current nature, it can also be used in areas where energy conservation is important, such as solar powered systems or signal lights. The LN85RP can also be widely applied in more diverse areas such as smartphones, digital cameras, and household lighting. The LED's compact size make it suitable for applications with limited space. Its low-current nature and precise light output also make it a popular choice for display panels or backlight source.

Working Principle of the LN85RP

The LN85RP discrete LED is a gallium indium phosphide (GaInP) light emitting diode. The LED consists of a semiconductor light generating element and a lead frame which connects the electrodes. The GaInP alloy acts as a semiconductor and generates light. The forward voltage of the device is around 2.1V, and it has an average power dissipation of 0.08W.The working principle of this LED is simple. When an electrical current is applied to the electrodes, the electrons and holes formed in the semiconductor recombine and the energy released is emitted as light. The color of the light is determined by the material used to produce the semiconductor. In the case of the LN85RP, this is a red-oriented light.

Conclusion

The LN85RP is an efficient and easy to use discrete LED for a wide range of application fields. Its low-current nature and precise light output make it an excellent choice for automotive, consumer, and solar automation applications. The device's simple working principle ensures a low power dissipation and a long life span of up to 10,000 hours. Thus, the LN85RP is an ideal choice for high efficiency and reliability.
