LED lamp aluminum substrate laser marking uses high-energy laser to form strong oxidation marks or fine etching on the surface of aluminum. Its main content covers key information such as model specifications, polarity identification, production batches, and traceable QR codes. This permanent marking method is consumable free, pollution-free, and can effectively resist high temperature, high humidity, and long-term light aging, ensuring clear and distinguishable information throughout the entire life cycle of LED lamps. Clear and accurate labeling is crucial for automated surface mount positioning, electrical safety warning, and subsequent quality control traceability. It is an important process link to ensure product reliability and brand value.
