Tube Bulb Worker (Light Bulb Manufacturing)
かんきゅうこう
Industry & Occupation
Classification
Summary
Tube bulb workers are craftsmen who blow-mold glass tubes, attach electrodes, evacuate vacuum, and seal them through various processes to manufacture light bulbs and discharge tubes.
Description
Tube bulb workers are specialists who manufacture glass tube products such as light bulbs, fluorescent lamps, and neon tubes. The main tasks include heating glass raw materials and blow-molding them with a blowpipe, attaching electrodes, evacuating air with a vacuum pump, and sealing operations. They require high-temperature burner handling and precise glass processing skills, while maintaining strict quality standards for product dimensions, vacuum levels, and more. Work is primarily hands-on in factory lines or small workshops, and they also handle manufacturing discharge tubes for special applications.
Future Outlook
Due to the spread of LED lighting, demand for general light bulbs is declining, but niche markets for discharge tubes for special applications and high-end decorative lamps will persist, and demand for personnel with precision glass processing skills is expected to remain.
