LED, or light-emitting diode, is a small signal light that is widely used in modern applications. They come in a variety of colors and sizes and can be used for many different purposes. In order to better understand how LEDs work, let’s focus on the specific type of LED, known as the LNJ8L6C18RA, a device used in discrete LED indication. The application field and working principle of this type of LED will be discussed in this article.

Application Field

The LNJ8L6C18RA is typically used in pushbutton switches as a discrete indicator light. As the current is increased, the brightness of the LED increases, helping the user to clearly identify when the switch is pressed. This type of LED is also used in keypads, panels and other types of switches, where it can provide direct feedback on the switch’s position or state. The LNJ8L6C18RA is also well-suited for illumination in car interiors, providing a clearer and more even light than traditional white LEDS.

Working Principle

To understand how the LNJ8L6C18RA LED works, it is important to understand how LED works in general. An LED is a diode with a forward voltage drop such that electrons flow from the cathode to the anode, resulting in the release of energy in the form of a photon. This photon makes the LED emit light. In order for the LNJ8L6C18RA LED to emit light, the current must be increased- the greater the current, the brighter the LED will be. The efficiency of the LED is determined by the amount of current that is applied to it. The current can be regulated using a current limiting resistor.

The LNJ8L6C18RA LED has a forward voltage of 1.8V and a maximum current rating of 20mA. This indicates that the LED will require at least 1.8V to turn on and no more than 20mA of current should be applied to it. To power the LED, a voltage source is needed, either a battery or a voltage regulator. In addition, a current limiting resistor must be used to prevent the LED from being overdriven, which can lead to damaging it.

Conclusion

The LNJ8L6C18RA LED is a type of light-emitting diode that is commonly used in discrete LED indication applications such as Pushbutton switches, keypads and panels. The working principle of this device is based on its forward voltage drop- when the current is increased, the brightness of the LED increases. To power the LED, a voltage source and a current limiting resistor are needed. With its versatility and low cost, the LNJ8L6C18RA is ideal for many applications and provides a bright and reliable source of light.
