How Does LED works?
Semiconductor Material: At the heart of an LED is a semiconductor material. Commonly used materials include gallium arsenide (GaAs), gallium phosphide (GaP), gallium arsenide phosphide (GaAsP), and indium gallium nitride (InGaN). The choice of material determines the colour of light emitted by the LED.
P-N Junction: LEDs are made of a P-N junction, where P represents the positively charged side (the anode) and N represents the negatively charged side (the cathode). When a voltage is applied to the LED, electrons from the N-type material move towards the P-type material, while positively charged "holes" from the P-type material move towards the N-type material.
Electron-Hole Recombination: As electrons and holes move towards each other across the junction, they recombine. When this recombination occurs, energy is released in the form of photons, which are packets of light. The energy of these photons determines the colour of light emitted by the LED.
Energy Band Gap: The energy band gap of the semiconductor material determines the energy and therefore the colour of light that the LED emits. LEDs with larger band gaps emit higher energy (shorter wavelength) light, such as blue or ultraviolet light, while those with smaller band gaps emit lower energy (longer wavelength) light, such as red or infrared light.
Encapsulation: The semiconductor chip is encapsulated in a solid plastic lens, which focuses the light and protects the semiconductor material from environmental factors such as moisture and mechanical damage. The lens also helps in controlling the light's directionality.
