Glass sleeves are crucial components in lighting and electronic applications, prized for their versatility and durability. Made from quartz glass, which provides exceptional optical clarity and strength, these sleeves can be adapted to various sizes. They are primarily used in the production of incandescent bulbs and semiconductor diodes, offering low packaging temperatures, compact size, and high shielding capabilities. Furthermore, glass sleeves play an essential role in LED manufacturing, encapsulating and protecting LED semiconductor chips to ensure longevity and optimal performance.
