LED indications are used for many different purposes, from displaying information about a product, or being used as warning indicators, to being used for general illumination. LED indicators are used for both digital and analog applications, and the type of indicator used will depend on the application. TLHB5401 is a type of LED indication developed for discrete applications, and this article will cover its application field and working principle.

TLHB5401 Application Field

TLHB5401 LED indication has been designed for discrete applications, meaning that they usually have one LED per input or output. The UL recognized LED indication has a 1.2cc package, allowing it to be used in environments which may have vibration, shock, or exposure to chemicals. The TLHB5401 has an operating temperatures range of -25 to +105 degrees Celsius, and a maximum reverse voltage of 6V. This LED indicator also has a wide range of standard colours, from red, green, yellow and blue, as well as white and wide range of pure colours. The standard chromaticity of the TLHB5401 is ±0.0020 CCT, meaning that colours stay the same, regardless of supply voltage.

The TLHB5401 can be used for many applications, such as automotive, industrial, medical, and military. The UL recognised indicator is also used for electrical products testing and process control, home appliances, and instrumentation. It is designed to be used in products which have limited space, have a rugged environment, or have static dissipation requirements, as the TLHB5401 has excellent static dissipation.

TLHB5401 Working Principle

The TLHB5401 LED indication uses a hysteresis control circuit, meaning that the current for the LED is increased when input voltage is increased, and vice versa. This allows for stable, consistent illumination of the LED, at a range of different voltages. The hysteresis control also has the added benefit of eliminating the power source noise which may affect the LED indicator’s output. The TLHB5401 LED indication also has a built-in temperature compensation circuit, which helps to keep the temperature of the LED stable and reduce the need for cooling of the LED indicator.

The LED indication also has a wide range of LED emission intensities, with luminosity ranging from 10 mcd to 110 mcd, depending on the supply voltage and LED used. This allows the LED indication to be used in any environment, providing the required brightness of the LED indicator.

Conclusion

The TLHB5401 LED indication is designed for discrete applications and is UL recognised, allowing it to be used in a wide range of environments. The LED indicator has a hysteresis control circuit for stable, consistent illumination, and a temperature compensation circuit to help reduce the need for cooling. The TLHB5401 has a wide range of LED emission intensities, making it suitable for any environment.
