Molybdenum wire in lighting industry application
Molybdenum is a metal with high melting point, high strength and excellent electrical conductivity. Due to its unique physical and chemical properties, molybdenum wire is widely used in the lighting industry, especially in traditional lighting equipment such as incandescent lamps, halogen lamps and fluorescent lamps.
Molybdenum wire applications in incandescent lamps
Incandescent lamp is the earliest large-scale application of the electric lamp form, molybdenum wire played a key role in it. Incandescent lamps work by heating tungsten wires with an electric current to make them glow. However, tungsten wires need to work stably in an inert gas environment for a long time. Molybdenum wire is used to support and hold tungsten wire, because molybdenum has a similar coefficient of thermal expansion to tungsten, and will not cause tungsten wire deformation or fracture at high temperatures. In addition, the high melting point of molybdenum wire (2623°C) allows it to maintain structural stability in the high temperature environment of incandescent lamps.
Molybdenum wire application in halogen lamp
Halogen lamps are improved versions of incandescent lamps that increase the life and efficiency of the bulb by adding halogen gas. The role of molybdenum wire in halogen lamps is similar to that of incandescent lamps, which are mainly used to support tungsten wire. Because halogen lamps operate at higher temperatures, molybdenum wire's high temperature stability and corrosion resistance make it an ideal material choice. Molybdenum wire can maintain chemical stability in the halogen gas environment to prevent the filament from rapidly aging or breaking at high temperatures, thus extending the service life of the lamp.
Molybdenum wire application in fluorescent lamps
Fluorescent lamps rely on arc discharge and phosphor luminescence, in which molybdenum wire is mainly used for electrode materials and support structures. The start-up and stable operation of fluorescent lamps require reliable electrodes, and the excellent electrical conductivity and oxidation resistance of molybdenum wire make it an ideal choice for electrode materials. Molybdenum wire can be stable in the high pressure and high temperature environment in the fluorescent tube to ensure the long-term reliable operation of the lamp.
Molybdenum wire application in LED lamps
Although LED lamps are gradually becoming mainstream lighting products, molybdenum wire still plays an important role in LED packaging and heat management. In high power LED lamps, molybdenum wire is used as a conductive bridge and heat dissipation channel. Molybdenum's high thermal and electrical conductivity helps to quickly dissipate the heat generated by LED chips, ensuring the high efficiency and long life of LED lamps.
Advantages of molybdenum wire
High melting point: The melting point of molybdenum is as high as 2623°C, so that it can remain stable in a high temperature environment and is not easy to melt or deform.
Good electrical conductivity: Molybdenum has good electrical conductivity to ensure the efficient transmission of current and improve the luminous efficiency of lamps.
Corrosion resistance: Molybdenum shows excellent corrosion resistance under high temperature and chemical environment, extending the service life of lamps.
Low coefficient of thermal expansion: molybdenum has a low coefficient of thermal expansion, which can be matched with other metals such as tungsten to prevent structural damage caused by inconsistent thermal expansion.
Mosten Alloy can produce molybdenum sheet, molybdenum block, molybdenum foil, molybdenum rod, molybdenum wire, molybdenum processing workpiece according to customer demand.
