Illumination Spot Measuring and Analysis in classrooms, Faculty of Public Health, Khon Kaen University

Abstract

Lighting is important for living life. Teaching activities depend on
lighting. Insufficient and over lighting values can affect to health and quality
of work.
This research was to measure illumination in lecture classrooms.
There were 22 rooms using Lux meter for Spot measurement between
JuneJuly 2016. The standards for lectures lighting was 400 Lux. There
were 378 spots for measuring. 235 (62%) spots were passed and 143 (38%)
spots were unpassed. The most lighting values was in 1310 room (1,030
Lux) (95% CI; 766.31,295.1), Pvalue=0.9998 and oppositely Phukao room
found the least lighting values (123 Lux) (95%CI; 98.5147.5), Pvalue=
0.0001.
Main causes of unpassed lighting spots were insufficient of lighting
lamps, no lamp maintenance. There have curtains partition entrance of
outside light sources. So setting a schedule for cleaning and changing lamps
should be adjusted for size classrooms
