LED indicators are discrete light sources that have become increasingly popular as an alternative to traditional incandescent and fluorescent lighting. They are available in a wide variety of shapes, sizes and colors, and offer a variety of light source types. One of the more common types is the QBLP679E-IGK series. This particular series is capable of functioning in a variety of application fields, has a long lifetime and is energy efficient.

The QBLP679E-IGK series is most commonly used as a means of providing an indicator of the power or load being supplied to an electrical device. This indicator acts as a way of easily identifying the state of the device at a glance, thus allowing for easy troubleshooting should the device require it. The series features a single color (red, green, blue or white) that is visible from any angle. It is also highly resistant to shock or vibration.

The external appearance of the QBLP679E-IGK series is that of a small, rectangular or cylindrical lens encased in a solid-state plastic housing that is then secured to a board or surface. Inside the lens are three LED (Light Emitting Diodes) components that are sealed against a protective epoxy shell. The entire assembly is usually waterproof and has an electrical current rating of 40mA. Each LED has a maximum forward current rating of 10mA.

In order to ensure its reliability, the QBLP679E-IGK series is designed to only work when the device is under a certain predefined load. For example, if the device is drawing more than 16mA, then the LED will not light. This is done to protect the LED from being damaged by any excess load placed on the device.

The working principle of the QBLP679E-IGK series can best be described as “on/off”. When the LED is in its “on” state, it will emit light at its peak brightness. It will revert back to its “off” state when it no longer detects an electrical load that is above its predefined threshold. This threshold is adjustable and is generally set at 16mA.

The QBLP679E-IGK series is ideal for a variety of applications, such as: power supply monitoring, power supply determination, voltage/load regulation, over-current protection and motor control. In some instances, it may also be used to provide a visual cue to the user with respect to the device’s operational status. This can be achieved by using the appropriate colour to flash at different rates.

In summary, the QBLP679E-IGK series is a robust, energy-efficient and reliable LED indicator that is used in a variety of application fields. It has a single, powerful LED output and can be used to provide a visual cue to the user to indicate the state of the device and its various parameters. Combined with its resistance to shock and vibration, the QBLP679E-IGK series is an excellent choice for any application requiring discrete light output.
