Its low power consumption in combination with low price makes it ideal for used for energy-saving designs in a variety of public and commercial places. Moreover, the long life of the QL484ET can significantly reduce maintenance and replacement costs for its customers.

Working principle of the QL484ET

In order to understand the working principle of the QL484ET, we need to first look at how a LED works. The LED is a semiconductor device which is composed of a PN junction diode, an electric field and a current-carrier zone. When electric current flows through the device, the electric field will force the current carriers to move to the PN junction boundaries. This energetic recombination of the charges at the junction boundaries produces visible light. The QL484ET LED has two cathodes, two anodes and one common-anode connection.

QL484ET works by using two circuits in combination. The first circuit consists of two side LEDs, one of them is connected to the anode terminal and the other is connected to the cathode terminal. When the LED is in the ON state, electric current flows from the anode to the cathode, causing the LED to emit light. The second circuit is a “bump type” circuit which is designed to provide an adjustable voltage source. This allows the user to adjust the brightness of the LED by adjusting the voltage applied to the LED. This makes the QL484ET a very versatile LED, which can be easily adapted to different lighting applications.

To conclude, the QL484ET provides a low cost, durable and ultra-bright LED discrete indication for industrial, commercial and residential applications. The adjustable voltage source helps users to customize the brightness according to their requirements. Furthermore, the long life of the QL484ET can really make a difference in terms of cost savings and environmental friendliness.
