LED is an abbreviation for light emitting diode in English. Its basic structure is an electroluminescent semiconductor material chip, which is cured onto a bracket with silver or white glue, and then connected to the chip and circuit board with silver or gold wires. The chip is then sealed with epoxy resin around it to protect the internal core wires. The installation of the housing ensures that the LED light has good seismic performance. The application areas involve daily household appliances and machinery production such as mobile phones, desk lamps, and home appliances.Reasons for yellowing of LED beads:It is the fluorescent powder in the LED beads that has been poisoned. When the fluorescent powder is invaded by sulfur or sulfides, poisoning occurs, mainly manifested as blackening and deterioration, losing the function of the fluorescent pool powder, causing the ...

At present, although the demand for LED lighting in the market is still heating up, many large-scale lighting engineering orders have quietly shown signs of delay. The unprecedented size of the market has led to fierce competition among industry players. In some common areas such as home furnishings, roads, and engineering, the market share of products such as light bulbs and tubes is already minimal. In this situation, some manufacturers are trying to find their own way in the field of special lighting applications. LED invests in printing technology while still being environmentally friendly and energy-saving In recent years, as LED technology continues to expand, the increasingly severe environmental problems have raised people's awareness of environmentally friendly products, and LED printers have begun to receive attention. LED printing actually uses light-emitti...
