LED indication has long been used in a variety of applications, ranging from signalling to aircraft navigation lights. In modern times it is also seen in numerous decorative applications, especially in the automotive and consumer electronics industries. LED indications can be discrete or multipoint (multi-colored and/or multi-state). The QLMP-LM85-34QDD is part of the discrete LED indication range and is used to signify the presence of an electrical current in the circuit that it is connected to.

Operation Principle

The QLMP-LM85-34QDD operates on a principle of DC versus AC. The light emitting diode (LED) within the unit is configured so that it will only light when current flows through it in one direction. This is achieved by the unit being implemented in a differential circuit.

The circuit has two separate conductors, one of which is connected to the anode of the LED and the other connected to the cathode. When sufficient current is input to the circuit and there is little difference between the two current sources, the LED remains un-illuminated.

When, however, the voltage of the anode exceeds the voltage of the cathode, the LED lights up, providing a visual indication. The amount of current being sent through the circuit is irrelevant, as long as the anode current is significantly larger than the cathode current. This is the basic principle behind the operation of the QLMP-LM85-34QDD.

Application Fields

The QLMP-LM85-34QDD is suitable for a variety of applications where a discrete LED indication is required. This includes everything from simple error indications in consumer electronics, to more complex warning signals and even the control of power automation systems.

The LED indication can be used to monitor the status of a system, from electrical current levels to power outlet settings. It can also be used to quickly access critical information such as operational states, system settings and even the temperature of a device.

In medical applications, for example, the LED indication can be used to monitor patient status or to indicate alarms when critical conditions arise. This is especially important when dealing with potentially hazardous equipment, since an LED indication can provide the user with a quick indication of the status of the system.

The LED indication can also be used in industrial environments, to indicate levels of production and limit switches, as well as other indicators such as pressure and temperature. Here again, the quick visual indication provided by the QLMP-LM85-34QDD can be invaluable in controlling the environment.

The wide range of applications in which the QLMP-LM85-34QDD can be used means that it can be implemented in countless different scenarios, depending on the requirements of the particular application. In any case, the flexibility of the device and its ability to provide a quick and reliable indication make it an invaluable asset in any system.
