Plug-n-play 3mm, 5mm LED lights

1. What is an LED?

• An LED (light-emitting diode) is a type of semiconductor tool that generates light by allowing an electric current to flow through it. This light is created when electrons combine with electron holes in the semiconductor, causing the discharge of energy in the form of photons. The color of the produced light is determined by the energy bandgap of the semiconductor material, which dictates the energy of the photons.

2.Buy LEDs in a shop near you

• LEDs are commonly available in most hardware electronics shops around you or any electronic components shop.

3.What is the price of a light-emitting diode (LED)?

• LEDs are fairly cheap and can be obtained for as low as Rs 1 or 2/- depending on the kind of LED that you are looking for. However most sellers sell LEDs in kits or combos which include different colours or packs of 100.

4.What is an electronic component, LED? What does LED stand for?

• LED stands for Light Emitting Diodes. LED is basically a p-n junction semiconductor (diode) that emits photons upon the application of electric current across its diode junction. The wavelength (or colour) of the photon depends on the semiconductor material used in making the LED

5.What are the different types of LED lights?

• There are a few different types of LEDs based on their application
  • Miniature LEDs
  • High power LEDs
  • Application-Specific LEDs
  • Lighting LEDs
  • Alphanumeric LEDs
  • RGB or Red Green Blue LEDs
  • Bi-color and Tri-color LEDs

6.What are the LED applications?

• As emitters or detectors generating photocurrent
  • Small LEDs are usually used as indicators, to indicate to the user if a particular circuit or board is functioning. For example, the drive activity LED on your PC blinks whenever you drive is being used
• LED displays
  • Millions of tiny LEDs are arranged in a grid to make the modern LED and OLED displays.
• Decor
  • LEDs these days are also used as decor and accenting components that are used to enhance a particular item. For example, LED strips make excellent ambience elements.

7.Other than LED, what are the other electronic components that should be a part of my project kit?

• Resistors are a must buy along with LEDs since they help control the voltage at the desired value, so that the LED doesn’t blow up. Different values of resistor are available, and should be chosen based on the required value.
• Other components include Inductors, Capacitors, Lasers/Diodes, Transistor, Potentiometer, etc; but the exact components that you may need depend on your project requirements.
• If you are a newbie to the world of Electronics, Microcontrollers or Robotics, it is highly recommended to purchase a kit that includes all essential electronic components (passive and active) to get started with, including LEDs.
