[0002] LED beads are light-emitting diodes with advantages such as high efficiency, energy saving, long lifespan, and fast response. They are widely used in lighting and display screens. LED beads mainly consist of an LED chip, packaging material, and electrodes. The LED chip is the core component that emits light and is usually made of semiconductor materials, such as gallium nitride (GaN). The packaging material protects the chip and improves optical performance; common materials include epoxy resin. Electrodes connect the chip to external circuitry, allowing current to pass through the chip and emit light. The working principle of LED beads is based on the photoelectric effect of semiconductors; when current passes through the LED chip, electrons and holes recombine in the chip. LEDs release energy and emit light in the form of photons. They have high luminous efficiency, converting more electrical energy into light energy, resulting in significant energy savings compared to traditional light sources. LEDs typically have a lifespan of tens of thousands of hours or even longer, reducing the hassle of frequent replacements. Their short response time allows for rapid lighting and extinguishing, making them suitable for applications requiring quick response. LEDs are also small in size and weight, facilitating design and installation. Furthermore, they do not contain harmful substances such as mercury, reducing environmental pollution.
