Filament Worker
ふぃらめんとこう
Industry & Occupation
Classification
Summary
A manufacturing job that uses tungsten wire to form and process filaments for light bulbs and electron tubes, performs inspections, and hands them over to subsequent processes.
Description
Filament workers mainly manufacture tungsten filaments for light bulbs and electron tubes. They adjust the tungsten wire to the specified diameter and length, and wind it spirally using a dedicated winding machine. Then, they perform welding to lead wires, resistance measurement, and microscopic inspection of the appearance to confirm quality that meets standards. The products are passed to vacuum sealing processes or assembly processes, and they undertake the foundational process to ensure stable light emission characteristics and long life.
Future Outlook
Due to the spread of LED lighting, demand for filaments in general lighting is on a declining trend. Demand for technicians specialized in niche markets such as electron tubes and special lamps will continue, but multi-skilling and automation are expected to advance in the future.
