ABSTRACT
Background:
Lighting plays an important role in the vision. The proper lighting of the class affects the student's well-being and reduces eye fatigue during learning. The aim of this study is to assess illuminance and illuminance uniformity of lighting in classrooms according to the Polish Standard PN-EN 12464-:2012.
Material and Methods:
Lighting was assessed in 28 classrooms of 10 schools in the cities of Silesia in Poland. With the use of a digital light meter (Lutron’s type Lx-105) illuminance on students’ desks and blackboards were measured. In addition, a questionnaire on subjective evaluation of lighting in classrooms was disseminated among students aged 13–15 years.
Results:
The average illuminance on the desks was 334 lx (SD=153), while the average value at boards was 183 lx (SD=91). Only 57% of classrooms met the requirements of the Polish Standard PN-EN12464-1:2012 concerning illuminance on the desks (300 lx). However, in none of the tested classrooms illuminance on the blackboards was adequate and according to the recommended standard (500 lx). The values of illumination uniformity on school desks was 0.75 (SD=0.14) and the value at boards was 0.79 (SD=0.1). According to the survey, 52% of the students were satisfied with the light in classrooms, while 26% of the respondents were dissatisfied with the lighting on the blackboards. 9% of the respondents reported that at least half of the fluorescence lamps in luminaires were dead.
Conclusions:
Lighting in schools in the cities of Silesia is very diverse. Illuminance at desks in almost half of the school classes and lighting on blackboards in all classrooms do not meet the requirements of hygienic standard and requires improvement. Light reflection needs to be eliminated and faulty fluorescent lamps changed.
