Discrete LED indication technology plays an increasingly important role in providing discrete and reliable status information to operators and monitoring systems. Finding the right LED device for a particular application is critical, as the environment and expected performance will determine the best LED device to use. The TLHG6201 LED indicator is a robust device suitable for applications that are exposed to extreme conditions and require steady performance. This article will explain the application field and working principle of the TLHG6201.

TLHG6201 Application Field

The TLHG6201 is a highly efficient, bright light emitting diode (LED) that can be used for a variety of applications. This device is designed to be visible from long distances, making it ideal for outdoor or commercial signage. The compact design of the TLHG6201 also makes it suitable for use in instrument panels, relays, and switches to indicate operation or fault conditions. Additionally, this device does not require a cooling system and ensures consistent performance in even the most extreme environmental conditions. This makes this device suitable for applications where extreme ambient temperatures, shock, vibration or corrosion is a factor.

TLHG6201 Working Principle

The TLHG6201 operates using a simple principle called electroluminescence. The device is comprised of a silicon carbide substrate, layered with a gallium nitride (GaN) active material. When a low power current is applied to the device, electrons in the device’s active material become excited and release a photon (light) with a wavelength of 490 nm. This enhances the visibility of the device in a variety of unlit and backlit environments.

The efficiency of the TLHG6201 can be further enhanced by adding a transparent LED encapsulant to the LED. This encapsulant increases the efficiency of the LED by reflecting back any unabsorbed light and redirecting it towards the viewing area. This creates an increased luminous intensity, allowing the TLHG6201 to be used in applications where energy savings is a priority. Furthermore, the device is also designed with a light-emitting surface constructed of transparent plastic and silicone that further aids in the reflection of unabsorbed light.

Conclusion

The TLHG6201 is a robust and reliable LED device for multiple applications that are exposed to extreme conditions. The device operates using the principle of electroluminescence, and offers a high efficiency rating, due to the use of a transparent LED encapsulant and light-emitting surface. This device is suitable for outdoor or commercial signage, instrument panels, relays, and switches to indicate fault or operation conditions, and it ensures consistent performance in harsh environmental conditions.
