Light Emitting Diode
What is LED
Light emitting diode, abbreviated as LED, is a commonly used light emitting device that releases energy through electron hole recombination and emits light. It is widely used in the field of lighting.
Light emitting diodes can efficiently convert electrical energy into light energy and have a wide range of applications in modern society, such as lighting, flat panel displays, medical devices, etc.
This type of electronic component appeared as early as 1962. In the early days, it could only emit low luminosity red light, but later developed other versions of monochromatic light. The light it could emit now covered visible light, infrared light, and ultraviolet light, and its luminosity was also increased to a considerable level. And its original use was also as an indicator light, display board, etc;
With the continuous advancement of technology, light-emitting diodes have been widely used in displays and lighting.
FBelec's existing four series of products are: DIP LED, the new SMD LED, Optocouplers, LED Lighting application, with stamping, plating, packaging, application of a complete industrial chain and the world's leading packaging equipment. KENTO produces more than 160 specifications of LED devices with an annual capacity of 12 billion pieces, ranking first in the country; new SMD LED production line with annual output of 1 billion pieces, optocoupler 817,357,3H7,etc., with annual production capacity of 1 billion; also with strong development strength on LED interior lighting, flexible lights, electronic display application.
Commonly called LEDs, are real unsung heroes in the electronics world. They do many different jobs in all kinds of devices. They form numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a jumbo television screen or illuminate a traffic light.
Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike incandescent bulbs, they don't have filaments that burn out, they use less electricity, and they don't get especially hot. They're illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The life span of an LED surpasses the short life of an incandescent bulb by thousands of hours. Because of these advantages, tiny LEDs are one of the most popular technologies used to light LCD TVs.
LEDs have come a long way since the early days of lighting up digital clock faces. In the 2000s, LCD TVs took over the high-definition market and represented a huge step over old standard definition CRT televisions. LCD displays were even a major step above HD rear-projection sets that weighed well over 100 pounds (45.4 kilograms). But LED technology changed the market. While LCD TVs were far thinner and lighter than massive rear-projection sets, they still used cold cathode fluorescent tubes to project a white light onto the pixels that make up the screen. Those add weight and thickness to the TV set. LEDs solved both problems.
LEDs are all around us: In our phones, our cars and even our homes. Any time something electronic lights up, there's a good chance that an LED is behind it. They come in a huge variety of sizes, shapes, and colors, but no matter what they look like they have one thing in common: they're the bacon of electronics. They're widely purported to make any project better and they're often added to unlikely things (to everyone's delight).
What exactly is this LED thing everyone's talking about?
Unlike bacon, however, they're no good once you've cooked them. This guide will help you avoid any accidental LED barbecues! First things first, though.
