Due to its high melting point, stability, and efficient luminescence, tungsten wire plays a vital role in medical instrument lighting. Despite the continuous emergence of new technologies, tungsten wire light sources will remain an important choice for certain demanding applications. I. Characteristics of Tungsten Wire Tungsten wire’s high melting point allows it to withstand high operating temperatures, making it particularly suitable for medical devices requiring strong light output. Tungsten wire maintains structural stability at high temperatures, and its resistance increases…
