LED lighting, once the realm of science fiction and the aspiration of the tech savvy, has now become a reality, with LED light bulbs now becoming increasingly commonplace in households, shops and streets. But what exactly is LED lighting? In this article, we will go into detail as to what LED lighting is, what its application field is and its working principle.

To begin with, LED, or light emitting diode, lighting uses semiconductors and electricity to produce visible light. LED lights consist of LED chips with pins at each side, which are encased in an epoxy resin. Compared to traditional lighting technology, LED lighting is designed to have a longer lifespan, requires less energy and is much brighter than traditional lights. LEDs are highly efficient and typically have up to a 30-year useful life expectancy.

When it comes to the application field of LED lighting, its use is vast. LEDs are being used for backlighting for LCD televisions, car instruments, and lighting for decorative purposes. In terms of landscape lighting, LED lights are now becoming increasingly popular, with their color changing capabilities and low-energy use making them a more efficient and cost-effective option compared to traditional lights. In addition, LEDs are used in cars, streetlights, stage performances, emergency lights and traffic signals.

The working principle of LED lighting is relatively simple; electricity passes through the LED chip, causing the electrons to move from the n-type material to the p-type material. This process creates an energy band gap, which results in photon emission – usually in the form of visible light. The amount of light produced is determined by the current passing through the LED chip and the voltage supplied.

In order to get the most out of LED lighting technology, it is important to understand its working principle. This involves becoming familiar with the different components and how they work together to produce light. The LED chip is the most important component, as it houses the actual light-emitting diode. Other components include a circuit board, the components which control the flow of current and the plastic casing that protects the LED chip.

LED lighting is now a go-to option for many people looking for an efficient and cost-effective form of lighting. Its application field is vast, with its usage spanning from car instruments to stage performances. Its long lifespan, low-energy use and bright illumination are just a few of the many benefits of LED lighting technology.

In addition to being a great lighting option, understanding its working principle can help people make informed decisions about their lighting needs. By familiarizing yourself with the components and understanding the basic process of LED lighting, you can be better prepared to make the best choice for your lighting needs.
