A SURVEY AND MEASUREMENT BASED STUDY ON DIMMABLE LIGHTING TO EVALUATE VISUAL PERFORMANCE AND LIGHTING ENERGY SAVINGS

Energy saving has been one of the most important issues discussed in lighting systems lately. One of the most common applications to provide energy savings in lighting are scenarios involving the utilization of dimmable gears. Although applying dimming provides good results in energy savings, its negative effects on the power network should not be ignored. Among the main negative effects are values such as harmonic distortion and power factor. These measurable magnitudes have been the most strongly emphasized parameters in scientific studies that have been carried out lately. When it comes to energy efficiency, parameters such as the visual perception, visual comfort, and the associated working performances of users should also be considered. These parameters cannot be as easily measured as the current, voltage, and harmonic distortions parameters. In this study, the disturbing effects of dimmable systems, which have an important value with regards to energy savings and efficiency on the power network, were investigated, while the negative effects experienced by users were also emphasized.
