Nowadays, From Televisions to Monitors, Tablets to Mobile phones and Banners to Hoardings everything Is equipped and running on LED’s. Therefore it is important to know the full form of LED’s and how they work
The full form of LED is a Light-emitting diode. It is a pn-junction diode that emits light when charged or activated.
How LED’s Work?
Many students from science backgrounds would like to know how the LED works.
When a measured voltage of electricity is applied by the leads, the electrons recombine through the holes and release energy in the form of photons. The phenomenon is called electroluminescence. The color of the LED is dependent upon the energy gaps of the semi-conductor.
There are many reasons why everyone prefers LED lights over other available lights or technology so let’s go ahead and discuss the benefits of LED lights.
Benefits of LED (Light – Emitting Diode)
• Energy Efficient Source of Lights
The main reason why LED’s have an edge over other forms of lights is that LED’s are very energy efficient. Studies say from a normal TV to an LED the running cost has been reduced to 70% also they do not produce heat, therefore, the cooling time is less, and LED does not have flickers or buzzing sounds if kept running for long.
• Long Life
The second important reason for LED’s been successful is that if installed properly LED lights can have a longer life than usual lights and at a very efficient running cost.
LED lights are environment friendly as they produce less heat as compared to other lights also they can be recycled unlike other lights available.
• Maintenance and Safety
LED lights do run at a very pocket-friendly cost and since they do not produce heat they are safe to install and remove even when they were running for long periods.
• Crystal Clear Picture Quality
With up gradations and advancement in technologies and AMOLED displays available in the market, one can enjoy an HD picture quality in1080 pixels and with a much better refresh rates everyone prefers to install LED TV’s over LCD and now the mobile phones are available in the market with AMOLED and since they are budget-friendly to install one can buy a decent phone or a TV at an attractive price with pre-installed LED’s.
FAQ’s (Frequently Asked Questions) on LED
• What are the different types of the LED?
– The different types of LED’s are designed using a change in Semi-Conductors. The most common LED’s are:
*Red Green Blue LED
• Can LED lights damage Eyes?
Yes, though LED lights are eco-friendly researches suggests that long exposure to LED lights can damage the retina of an eye resulting in partial or complete blindness.
• How to save eyes from LED lights?
Students or professionals sitting prolong in front of the computer should install a protective screen in front of the LED monitors or they can wear yellow spectacles while working. Yellow spectacles block harmful radiations and the blue color which damages the eye the most.
Hopefully, you now know the full form and benefits of LED lights and how they works. With the advancement in technology and continuous improvement in LED usage, you should know the basics of LED lights.
