LED Indication – Discrete

LEDs, or light-emitting diodes, are semiconductor devices that are used to emit light when an electric current applied to them. Discrete LEDs are often used for indicator lights in a variety of systems and applications, from low-cost hobby projects to critical military and industrial applications. The HLMP-AD87-RU0DD discrete LED is a bright green LED available in a 3-mm through-hole package that is popular for use in very tight spaces.

Applications of HLMP-AD87-RU0DD

The HLMP-AD87-RU0DD discrete LED is often used in a variety of applications. Its small size and high efficiency makes it suitable for use in:

• High-speed and high-accuracy electronic instrumentation;
• Vibration measuring systems, motion sensors and motion control systems;
• Electronic signage and alarm systems;
• Navigation systems, GPS devices and monitoring systems;
• High-speed industrial computing applications;
• Interactive gaming systems.

The HLMP-AD87-RU0DD is also popular for use in repair and troubleshooting applications, as its small size allows for easy diagnosis of issues in the field or on the factory floor.

Working Principle

LED devices are composed of two semi-conductive layers of material, with a thin dielectric layer between them. In a discrete LED, a thin semiconductor junction is placed between the base layer and the emitter layer, forming a p-n junction diode. When a voltage is applied across the junction, electrons are emitted from the emitter and fall into the base, releasing energy as a photon of light. This process is known as “electroluminescence” and is the basis of all LED operation.The HLMP-AD87-RU0DD LED falls into the class of through-hole LED devices, which means that it has three leads; an anode, a cathode, and a ground. The anode and cathode connections are used to apply a voltage across the LED junction, and the DLMP-AD87-RU0DD can be powered from a DC voltage source ranging from 1.8V to 3.6V.

Conclusion

The HLMP-AD87-RU0DD is a discrete LED made from a 3-mm through-hole package. Its small size and high efficiency make it ideal for tight spaces and for a wide variety of applications. It is often used in high-speed and high-accuracy instrumentation, vibration measuring systems, electronic signage, navigation systems, and more. Its working principle is based on Electroluminescence, wherein electrons are emitted from the emitter and fall into the base when a voltage is applied across the junction, releasing energy as a photon of light.
