LED Indication - Discrete
LED is short for light emitting diode, which is a semiconductor optoelectronic device. It works on the principle of electroluminescence, which converts electrical energy into light energy. LEDs are widely used in illumination, signal and display fields. The main usage of LEDs is for providing light source which can indicate status for equipment or systems, and thus are often categorized as LED Indication.
APD3224QWF/D Application Field and Working Principle
APD3224QWF/D is a 4 pins LED indicator amongst the LED Indication series from Kingbright, which can work with DC power from 3V to 24V and consume low operating current of 0.02A. Its pinouts include Anode, Common Anode (LED ground), Cathode and Common Cathode, which gives the APD3224QWF/D flexibility in applications. Some of the popular usage cases include indicator light in poer switch, signal, indicating light in a robot\'s eye, corridor or hallway light indicator and vehicle light indicator.
The principle behind the APD3224QWF/D LED Indication is to provide an optical system which the LED can be powered with an electrical potential. Its power source, the DC current, provides a potential difference between the Anode and Cathode, which in turn create a voltage across the PN junction of the LED resulting in current flow in the LED and corresponding light emission. The mechanism also translates to the reverse situation, where when a certain amount of current flows across the PN junction of the LED, the LED will begin to light up.
Types of LED Indication - Discrete
LED Indication is broadly categorised into two main types, namely discrete and integrated. The former type consists of single LEDs or set of LEDs which are used to indicate a specific event or decision. A few examples are indicator light in a game machine, a cluster of LEDs in a bus stop sign, stop lamps in vehicle, as well as play, fast forward and rewind buttons. Discrete LED Indication are relatively low cost and easy to put together, hence they can be seen in many places.
Uses of Discrete LED Indication
Discrete LEDs are frequently used in the area of machine vision and robotics. They are particularly useful in this field because of their ability to indicate the orientation of objects. In a manufacturing plant, for example, an array of discrete LEDs of different colors can be used to distinguish multiple objects on a production line. Similarly, discrete LEDs also plays a vital role in medical equipment. They are used to alert medical personnel to changes in environment or equipment, inform medical personnel when a certain measurement has been reached or warn medical personnel when a particular abnormality is detected.
Apart from their uses in medical equipment and machine vision, discrete LED Indications are also used in many household appliances. In the case of a refrigerator, for instance, various LED Indications can be used to display the current temperature in the refrigerator and alert the user when the temperature is outside the recommended range. Additionally, discrete LEDs are also often used in push-button switches and control panels, especially those which require a more visual indication as to the level of user manipulation.
Conclusion
In conclusion, LED Indication, particularly those of the discrete type, is a common and cost-effective way to be used within a wide range of applications, ranging from consumer products to medical equipment. The APD3224QWF/D LED Indication is a reliable and versatile way to utilize LED indication within electronic and illumination fields. In addition to its wide voltage range of from 3V to 24V and low operating current of 0.02A, the APD3224QWF/D is adaptable and flexible for various types of applications, making it an efficient and attractive solution for LED Indication.
