Led chip, also known as Light Emitting Diode (LED) chip, is a semiconductor device that emits light when an electric current passes through it. It is the core component of LED lamps and other lighting devices. The led chip consists of two types of materials: p-type (positive) and n-type (negative). When a forward bias voltage is applied to the p-n junction, electrons from the n-type material flow into the p-type material, releasing energy in the form of photons.

Description Of Led Chip
The led chip is a compact semiconductor device that converts electrical energy into light energy. It consists of a p-type and n-type material, which are combined to form a p-n junction. When an electric current flows through the p-n junction, electrons recombine with holes, releasing energy in the form of photons.
