Buying LED Lights Online

What is an LED light?

LED stands for ‘light-emitting diode’. LED emits light when the current flows from it, and it is a semiconductor. Electron holes recombine with electrons in the semiconductor which produces energy in the photons’ form. It is that semiconductor device that emits light when electricity is passed through it. When the particles carry current combined within a semiconductor, light is produced. LED’s are described as solid-state devices because the light is generated within the solid semiconductor material. The electrons and holes are contained within energy bands inside the semiconductor material of the LED. The bandgap determines the energy of photons that are emitted by the LED. 

To manufacture LEDs, the primary materials of semiconductor are:

  • Indium gallium nitride (InGaN): for blue, ultraviolet high-brightness and green LEDs.
  • Aluminium gallium indium phosphide (AlGaInP): for orange, yellow and red high brightness LEDs
  • Aluminium gallium arsenide (AlGaAs): for infrared and red LEDs.
  • Gallium phosphide. (GaP): for green and yellow LEDs.

Types of LEDs

There are several types such as

  • Dome LEDs
  • IR LEDs
  • 7 Segment display LEDs
  • Tri-colour LEDs

Colour LEDs and white LEDs are mostly used in lamps, indicators, lighting equipment etc. and they are mainly used LEDs. Then Tri or Bi-colour LEDs doesn’t change colour because they are two separate LEDs in one package. One turns on one or both at the same time to produce to our more colours. Infrared LEDs are mostly working on transmission frequency of 38 kHz.

To differentiate amongst other IR sources is often modulated at relatively high frequency to control the brightness. Some are modulated at a low rate to create a blinking effect. 7 Segment Display LEDs consists of 7 display LEDs in the form of an 8. Its used in TV monitors or calculators etc. UV LED’s have various applications such as water purification and sterilization etc. since it emits ultraviolet rays of light. 

LEDlights are readily available in the market, and you can even buy Led lights online. There are a vast range of LEDs that you can select and choose from, and before purchasing it, you can compare it to other Led lightsbrands when you’re looking online. Since the online market is vast, the prices are mostly present for comparison.

Now to buy Led lights online in India is very easy since there are several online sites accessible to the customers. The list of brands, their prices and warranties are all up for comparison. One can quickly sort and chose from the full range of products to satisfy their personal and commercial needs with those LED light. They can also select and customize the colour of the LEDs as they want. They have the facility to receive all the equipment at home and assemble an arrangement of LED as they like. They will be able to control the colours to the length. It is all in the hand of the customer, and the great things about LEDs are that they are readily available in the online Indian market and very handy in terms of the size and weight.
