What is the full form of LED
LED: Light Emitting Diode
LED stands for Light Emitting Diode. It is a two-lead semiconductor light source. It is a pn-junction diode which emits light when activated. It is a very important electronic device because it is used in a lot of electrical and electronic devices now a days. It is mostly used in electronic test equipments, TV’s, calculators, watches, radios, etc.
How LED works
Light-emitting diodes are semiconductor light producers that combine a type P semiconductor with a higher concentration of a hole and a type N semiconductor with a higher concentration of electrons. Applying a proper forward voltage at the P-N junction will cause the electrons and holes to recombine and release energy in the form of light.
Types of LED
The different types of LED are designed using semiconductors are listed below.
- Miniature LEDs
- Lighting LED
- Red Green Blue LEDs
- Flash LED
- High-Power LEDs
- Alphanumeric LED
Applications of LED
LEDs are used in various fields, including warning systems, optical communications and security systems, robotics, remote-controlled operations, etc. Due to its long-lasting capacity, low power demands, quick response time and rapid switching capabilities, it finds use in many of these areas such as
- Used in the automotive industry
- Used in TV backlight.
- Used in various displays
- Used in the dimming of light
