The QLMP-EJ58-XZ0DD belongs to the broad category of LEDs that are used for discrete indications better known as point indicators. This type of LED has a wide range of applications in industries and several other professions. Additionally, their working principle make them extremely useful when communicating important messages.

Application Field

Typically, the QLMP-EJ58-XZ0DD is used in industrial applications as an indicator of a status of an equipment, system or process. It’s such an effective point indicator because, due to its wide angle beam and relative power output, it can be seen from large distances and always be clearly visible no matter what type of environment it’s exposed to.

For example, it’s often used in mechanical overheating to indicate whether maximum temperature is about to be reached or exceeded. It is also used in pumps to mark status points of the cycle, switchboard, control panels, and other types of equipment. Moreover, this LED is also a popular choice in alarm systems and status signalling, particularly in high security areas such as manufacturing plants and other areas where precise indicators are required.

Working Principle

The QLMP-EJ58-XZ0DD is usually powered by a 12 volts-5 amps power supply. A circuit is used to limit and regulate the current flow to the LED which typically requires 150mA and 2.8 volts. It works by allowing current to flow through the LED when the power is applied, thus illuminating it. At the same time, it prevents the LED from burning out due to its low forward voltage drop.

The LED itself consists of three parts: the emitter, the collector, and the base. When current passes through the emitter, it then flows to the collector, which controls the intensity of the light. The base is the negative electrical connection that limits the current flowing through the LED. Together, these three components create a uniform and consistent light that is easy to read from a distance.

Conclusion

Discrete LED indicators, like the QLMP-EJ58-XZ0DD, are incredibly useful in providing simply and straightforward on/off status indicators for equipment and systems. When the current is flowing, the LED emits a distinct, intense light giving the user an easy way to tell when something is working. By regulating the current that passes through the LED, users can be sure that they will not have to worry about burning out the device.
