Barium tungsten electrodes have a variety of applications in optoelectronic products, mainly due to their excellent properties, such as low work function, high current density, good starting performance and large energy output. The following are some specific application areas:
HID lamps (high-intensity discharge lamps)
Barium tungsten electrodes are widely used in HID lamps due to their low work function (φ=1.6ev) and high current density (10A/cm²). These characteristics enable HID lamps to emit bright and stable light, suitable for occasions requiring high brightness and long-life light sources, such as road lighting, industrial lighting, etc.
Electric vacuum and laser devices
The low escape function of barium tungsten electrodes makes them often made into electric vacuum and laser devices. For example, in electric light source products, the electron emission performance of barium tungsten electrodes can reach a repetition frequency from low to high (1~40 times/second), which makes the prepared strobe lights have significant improvements in starting performance and brightness.
Stage and ballroom effect display
In stage and ballroom, optoelectronic products are often used to create various atmospheres and effects. High-frequency strobe lamps made of barium tungsten electrodes are ideal for these occasions due to their long service life (up to 5 million times or more) and stable performance.
Film and television projection and recording
In the film and television industry, barium tungsten electrodes are also widely used in projection and recording equipment. Its excellent performance can ensure that film and television equipment remains stable and efficient during long-term operation.
Laser mercury ion
In laser technology, barium tungsten electrodes are also used as electrode materials for laser mercury ion. Its high electron emission ability and low electrode operating temperature help to improve the performance and stability of the laser.
