Summary
Assembly line lighting in factories is often inadequate, with poor uniformity and no established standards for worker comfort or visual health. This study recommends specific illuminance levels to improve workplace conditions and reduce eye strain.
Area of Science:
- Industrial Engineering
- Occupational Health
- Lighting Design
Context:
- Current assembly line illumination in domestic factories is suboptimal.
- Worker well-being and visual performance are directly impacted by lighting quality.
- Existing lighting standards do not adequately address worker satisfaction or asthenopia.
Purpose:
- To assess current assembly line lighting conditions.
- To establish recommended illuminance standards for improved workplace environments.
- To correlate lighting parameters with worker visual comfort and satisfaction.
Summary:
- A survey of 752 workers across seven factories (textile, shoes, electronics) utilized questionnaires and field measurements.
- Statistical analysis revealed significant correlations between illumination uniformity, visual clarity, worker satisfaction, and asthenopia.
- Recommended illuminance levels for five distinct visual tasks range from 50-100-200 lx to 500-1000-1500 lx.
Impact:
- Highlights the need for improved lighting standards in industrial settings.
- Provides data-driven recommendations for enhancing worker visual comfort and reducing eye strain.
- Suggests further research and improvements in assembly line illumination practices.
