The WP1384AL/SRD is a mid-power infrared Light Emitting Diode (LED) from Lite-On, designed for use as an indicator in electronic equipment. Some common applications for the WP1384AL/SRD and other LEDs include backlighting, automotive lighting, signage, indicator lamps, and optoelectronic components. This article will cover the application fields and working principles of the WP1384AL/SRD.

Application Field

The WP1384AL/SRD can be used as an indicator in various types of electronic equipment, such as consumer electronics, industrial controls, medical devices, and more. It is often used as an indicate in consumer electronics because it is visually simple, highly customizable, and able to function in various environmental conditions. The LED has a low voltage drop, making it suitable for applications where an ultra-low power consumption is desired. The LED also makes for a cost-effective solution for industrial equipment, such as lighting, instrumentation design, and medical applications.

Working Principle

LEDs used in general lighting applications operate using a semiconductor device, which emits light when current passes through it. The WP1384AL/SRD contains an anode and a cathode, which can be connected in either a common anode or a common cathode configuration. The anode will usually be at a higher potential than the cathode, which will result in electrons crossing the junction between the two. When electrons cross the junction, they recombine with holes, producing light.

The current flow through the LED is regulated by the forward voltage, which is determined by the specific type of LED. The forward voltage is the voltage required to cause electrons to cross the junction and create light. Higher forward voltages produce brighter illumination, while lower forward voltages result in a dimmer, more subtle light.

The intensity of light that the LED emits is determined by the current flowing through the junction of the LED. LEDs can operate using either pulsed (AC) or direct current (DC). When AC current is used, the LED emits a pulsing light, and the rate of pulsing can be controlled by changing the frequency of the AC current. With DC current, the LED shines steadily and the light intensity can be controlled by adjusting the current.

Conclusion

The WP1384AL/SRD is a versatile LED that can be used for a variety of applications, from consumer electronics to industrial equipment and medical devices. Its working principle is based on a semiconductor device, in which electrons cross a junction between an anode and a cathode to create light. The forward voltage and current flowing through the LED must be regulated to produce the desired light intensity.
