QTLP9124YR Optoelectronics

LED indications unit play an important role in most of the applications like panel lighting, test and measuring instruments. In the past few years, discrete components for panel indications have been used in many applications. Amongst all the discrete components, the QTLP9124YR is the latest innovation. This article will discuss the QTLP9124YR application field and its working principle.

Application Field

The QTLP9124YR is a 12V, 8mA rated LED used in the panel indication market. It features an amber light with a full 180 degree viewing angle. It has a built-in photocell and a negative temperature control circuit which makes it an ideal choice in a wide variety of applications. The QTLP9124YR can be used in medical, automotive, industrial and consumer products. It is a suitable choice for controlling switches, electrical connections, wiring and lamps. It can also be used in dimmable lighting in homes to allow users to adjust the light levels according to the desired atmosphere. Its amber light adds a softer and warmer glow than white or other colors.

Working Principle

The QTLP9124YR works based on the principles of LED technology. When the LED voltage is connected to a power supply, the LED emits a specific wavelength of light. Depending on the applied current, the emitted lights will vary in brightness. To ensure proper operation, the voltage of the power supply should not exceed the breakdown voltage of the LED. A voltage regulator is necessary to ensure that the correct voltage is applied. The photocell and negative temperature control circuit of the QTLP9124YR help to regulate the intensity of the light emitted. The photocell allows the QTLP9124YR to adjust its light brightness as the ambient light levels change. The negative temperature control circuit ensures that the light emitted is consistent across different temperatures.

Conclusion

The QTLP9124YR is the latest in the market of discrete components used in panel indication. It is especially suitable for applications where accuracy and reliability is extremely important. It is used in medical, automotive, industrial and consumer products and is capable of regulating its light emission in synchronization with the ambient light levels. The QTLP9124YR works based on the principles of LED technology through the use of a voltage regulator, photocell and negative temperature control circuit. With its superior features, the QTLP9124YR is a great choice for LED indication customers.
