Lighting is an important factor in providing the appropriate learning environment at universities and educational facilities. It affects the learning outcomes and contributes to the aesthetic, psychological and health aspects of students, teachers and other users. Providing lighting is also costly and impacts on the environment. Thus, in choosing between competing lighting options an assessment...

The replacement of the disappearing incandescent lamps will be realized at a significant scale by compact fluorescent lamps (CFLs). Light regulation is a popular feature that is easily provided by incandescent lamps using a simple electronic equipment, the dimmer. Dimming can be achieved by (dimmable) CFL lamps as well, however this is done in a completely different way than in case of the form...

background : some characteristics of lighting sources such as color properties and ultraviolet emissions have important roles on visual and non-visual health effects of lighting. this study aimed to investigate the light emissions of some compact fluorescent lamps (cfls) and incandescent lamps commercially available to the iranian consumers. methods: sixty lamps included 48 single envelope cfls...

International EMC standards describe the measurement environment (setup, equipment, frequencies) and applicable limits for the electromagnetic emission testing of lighting equipment, including compact fluorescent lamps (CFLs). These standards consider the compact fluorescent lamp a ‘black box’. In order to better understand the emissions from this type of light source, the operation of the equi...
