Background & Objectives : The comfort lighting in the workplace provides employees visual health which can improve safety, visual comfort and enhance performance and product quality. The present study was conducted to evaluate general and local lighting in carpet weaving workshops in Bijar city .

Methods : In this descriptive analytical study, 101 carpet weaving workshops were randomly selected. The illuminance were measured based on the models and formulas presented in Illuminating Engineering Society (IES) using luxmeter model Hagner EC1 in height 76 cm from the ground surface. The local illuminances were measured in horizontal and vertical weaving level. Data were analyzed by SPSS software (version 16).

 Results : Research findings revealed the average of total and artificial illuminance level were 484.5±458.9 and 80.0±49.9 Lx respectively. Mean total, natural and artificial illuminance 39.6, 57.4 and 100 percent were lower the recommended 300 Lx levels. The average of minimum of local illuminance was less than 500 Lx in all workshops.

Conclusion : About 60% of workrooms had the acceptable general illuminance levels in middle day. However, due to the insufficient lighting sources in workshops, the artificial illuminance levels are unsuitable. Therefore, it is necessary to improve general illuminance levels by reform and repair artificial lighting systems or redesign them in carpet weaving workrooms.
