Working principle of chip SMD LED
Semiconductor Luminescence
The chip is made of semiconductor materials. When an electric current passes through, electrons and holes in the semiconductor recombine, releasing energy in the form of light, which is the principle of electroluminescence.
Current Injection
Under the action of an external electric field, current is injected into the semiconductor chip, providing the energy needed for electron - hole recombination.
Light Extraction
The light generated inside the chip is transmitted through the packaging material and the lens, and finally emitted to the outside to achieve the lighting effect.
Heat Dissipation Management
The heat generated during the operation of the chip is conducted out through the heat dissipation structure of the SMD package, ensuring that the chip works within a suitable temperature range and maintaining stable performance.
