LEDs, or more technically Light-Emitting Diodes, come in a variety of shapes and sizes and can be used for a plethora of purposes. This includes circuit board indicators, light bars, bar graphs, and arrays. While the applications for each of these is different, the general principle behind them is the same. As such, this article will discuss this principle and one particular type of LED, the KB2670EW, and its uses.
Principle Behind LEDs
At its core, the purpose of a LED is to produce light. This is done via the process of electroluminescence. Electroluminescence is a process by which electrons in a semiconductor pass through an energy barrier and release energy in the form of light. A LED is just a diode, or a two-terminal semiconductor, that is designed to use this electron flow to generate light as opposed to electricity. Reasons for LED use typically range from differentiating electronic circuitry, to lighting up signs and displays, or indication of conditions.Types of LEDs
LEDs can be categorized into several different types according to their projection angle, shape, size and other properties. The two main types are traditional LEDs and surface mount LEDs. Traditional LEDs are typically 3mm in diameter, whereas surface mount LEDs are much smaller and are typically around 1mm in diameter. The two main LED categories can be further subdivided according to their viewing angle, luminosity, intensity, color, and power requirements.KB2670EW Application Field and Working Principle
The KB2670EW is going to be used as a light source in digital displays and reading panels. It is a surface mount LED package which provides a wide viewing angle. It has a luminosity of 8,000 mcd and a forward voltage of 2.8V. The forward current is 50mA. The color of the KB2670EW is white which matches the current digital display trends.The principles behind the KB2670EW\'s operation is the same as any other LED. Within the package, majority charge carriers are injected into the device when the voltage is applied to the two leads. The carriers then recombine at an active region within the device and produce electromagnetic radiations in the form of light. This light then passes through a series of lenses and is coupled with plastic encapsulation that give the overall shape to the package.Conclusion
LEDs are incredibly versatile due to their ability to adapt to a variety of shapes, sizes and applications. The KB2670EW is just one of the many LEDs that has a range of applications including digital displays and reading panels. By understanding the principle behind LEDs and the properties of particular specific type like the KB2670EW, we can better determine what applications they’re best suited for.The specific data is subject to PDF, and the above content is for reference
