Glass beads, also known as glass sleeves, are essential components in lighting and electronic applications, valued for their versatility, durability, and environmental benefits. Made from either lead glass, which offers superior optical clarity and strength, or lead-free glass, which aligns with eco-friendly standards, these beads are adaptable to various sizes. They are primarily used in the production of incandescent bulbs and semiconductor diodes, providing low packaging temperatures, compact size, and high shielding capabilities. Additionally, glass beads play a crucial role in LED manufacturing, encapsulating and protecting LED semiconductor chips to ensure longevity and optimal performance.
