Filament and ionization line for sterilization lamps.

Filament and ionization line for sterilization lamps.

Gold plating (0.3μm thickness) and specially treated tungsten have also been developed and put into practical use!

We handle "filaments and ionization wires for sterilization lamps." In fluorescent lamps, ultraviolet light collides with fluorescent materials inside the tube to become visible light, whereas in sterilization lamps, ultraviolet light passes through the quartz glass tube without being converted, allowing for sterilization and disinfection of the external environment. The filaments used in sterilization lamps are coated with electron-emitting materials to facilitate the generation of thermionic electrons. Additionally, "ionization wires" are typically around 0.1mm in diameter due to discharge and strength considerations, but the wire diameter can be selected as needed. 【Features】 <Filaments for sterilization lamps> ■ Coated with electron-emitting materials to facilitate the generation of thermionic electrons ■ Coiled coils are used to increase the surface area, resulting in filaments that are wound in double or triple layers *For more details, please refer to the PDF document or feel free to contact us.

[Data] Improvement of Bulb Lifespan through Pitch Control

[Data] Improvement of Bulb Lifespan through Pitch Control

Improving the lifespan of light bulbs is an eternal challenge! Proposing filament shapes that can achieve longer lifespans.

This document explains "improving bulb lifespan through pitch control." It includes a detailed investigation of "defective bulbs" in 12V21W automotive bulbs and tests on filament design related to "lifespan improvement through variable pitch." Our company conducts filament analysis and proposes filament shapes that can achieve longer lifespans based on these insights. [Contents] ■ Investigation of defective bulbs ■ Tests on lifespan improvement through variable pitch *For more details, please refer to the PDF document or feel free to contact us.

Features of mandrel-less machines

Features of mandrel-less machines

The treatment of harmful gases and the disposal of dissolved waste liquids are no longer necessary, significantly reducing the burden on the environment!

We would like to introduce the features of our "mandrel-less machine." As the wire diameter decreases, the range of coiling becomes narrower, making manufacturing difficult. By introducing a servo motor and enhancing wire tension control technology, we have made it possible to finely manage the winding position and winding speed, enabling fine wire winding. Additionally, we offer "footed filaments," successfully manufactured using our unique winding technology that mechanically allows the core wire to enter and exit. 【Features of the Mandrel-less Machine】 ■ The manufacturing range has upper and lower limits depending on the required tungsten wire diameter. ■ As the wire diameter decreases, the range of coiling becomes narrower, making manufacturing difficult. ■ By finely managing the winding position and winding speed, fine wire winding becomes possible. ■ Treatment of harmful gases generated during the melting process and disposal of melting wastewater are no longer necessary. ■ Significantly reduces environmental impact. *For more details, please refer to the PDF document or feel free to contact us.
