Led lights

Led lights | A light who changed revolution 60 years ago

Led lights (Light-emitting diode) are the most used lights today. Whether it may be to use for study purposes or for decorating objects these lights are highly used. The main reason behind this is that it is cheap compared to fluorescent lights and it provides more output than others. Let’s check the working of led lights in detail.

Before checking the working of led lights, let’s check, what are led lights and its types,

What are led Lights?

A light-emitting diode light or led light is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. This effect is called electroluminescence.

The first led light was created by Russian inventor Oleg Losev in 1927.


Types and working of Led’s

Through-hole :

These LEDs are mostly used for and indication purpose, Red, Blue, Yellow, Green, White, etc. It is made in 3 shapes only 3 mm, 5 mm. and 8 mm.


SFD (Surface Mount Light Emitting Diodes) :led

These lights are well packaged and can be easily mounted on a PCB-(Printed circuit board.)


Bi-colour:This lights can emit two colours depending on its configuration.


RGB (Red Green and Blue ) :

Led lights

These lights are only used for decoration purpose, using an RGB led gains a lot of attention. All the gaming peripherals mostly uses RGB lighting to attract the customer.


Understanding this concept via diagram gets a little difficult so I’m uploading a link which may clear your doubts of working of led lights
