Molybdenum Ribbon for Discharge Lamp
Molybdenum ribbon for discharge lamp is a specialized material used in the construction of discharge lamps, particularly in the sealing process. Discharge lamps, such as halogen lamps or high-intensity discharge (HID) lamps, require precise sealing to maintain the integrity of the lamp and ensure proper operation.
The molybdenum ribbon used in these lamps serves several important functions:
Sealing: Molybdenum ribbon is used to seal the lamp components together, creating a hermetic seal that prevents gas or air from entering or escaping the lamp. This sealing process is crucial for maintaining the lamp's internal environment and preventing contamination or degradation of the lamp components.
Conduction: Molybdenum is an excellent conductor of electricity, making it ideal for applications where electrical conductivity is required. In discharge lamps, molybdenum ribbon is often used to provide electrical connections between different components of the lamp, ensuring efficient operation and reliable performance.

Thermal Stability: Molybdenum has a high melting point and excellent thermal stability, allowing it to withstand the high temperatures generated within the lamp during operation. This ensures that the molybdenum ribbon remains stable and maintains its structural integrity even under extreme conditions.
Compatibility: Molybdenum ribbon is compatible with the materials used in discharge lamps, such as quartz glass or ceramic. It forms a reliable bond with these materials, ensuring a secure and durable seal that can withstand the rigors of lamp operation.
The quality of the seal between the discharge lamp and the molybdenum ribbon depends on the mechanical structure, chemical interaction, humidity resistance, and surface purity. High-quality molybdenum sealing ribbon exhibits good consistency, excellent adhesion to the discharge lamp, good weldability, and oxidation resistance. The sealing weld is free from cracks, and the same material can be used for all applications.
