QL202HT is a discrete light-emitting diode (LED) indicator intended for use in applications and lighting such as interior, exterior, commercial, and military aircraft. This LED provides superior performance, especially when compared to filament indicators. Its long lifetime and low power consumption add to its durability, making it a great choice for any application requiring bright lighting and accuracy.

The QL202HT is a 2-conductor, high-efficiency, narrow band visible light-emitting diode. It has the capability to operate up to a maximum temperature of 105 degrees Celsius and can produce up to a maximum pulsed current of 40mA. It is qualified to MIL-STD-202G, making it suitable for a variety of commercial and military aircraft applications. The LED has a wide viewing angle of 45 degrees, making it ideal for most lighting tasks. The LED has a low power consumption of up to 2 watts, allowing it to be used in many applications without affecting the power consumption.

The working principle of the QL202HT LED is based on the basic LED principle. When a current is passed through a semiconductor material, energy is released in the form of photons which, in turn, emits visible light. In the case of this LED, the semiconductor material is made up of a combination of Gallium Arsenide Indium Phosphide (GaAsInP). The GaAsInP produces visible light when a current is passed through it.

Applications of the QL202HT LED include a wide range of commercial, industrial, and military aircraft applications. From indicating fuel levels and speedometers, to signaling altitude and airspeed, the QL202HT can be used in any variety of applications as its long lifetime combined with high efficiency make it ideal for many applications. Additionally, the QL202HT is also suitable for exterior and interior lighting applications where its energy efficiency and wide viewing angle make it a great choice for these types of applications.

In conclusion, the QL202HT LED is an excellent choice for any application requiring bright, efficient, and accurate lighting. Its long lifetime and low power consumption make it ideal for many commercial and military aircraft applications, while its wide viewing angle is great for exterior and interior lighting tasks. As a result, the QL202HT LED is a great choice when it comes to LED indication and illumination.
