Optical and Electrical Evaluation of Passive Infrared Sensor Equipped Lighting Fixtures in Turkey

Passive infrared (PIR) sensor equipped lighting fixtures are combination of a PIR sensor and a lighting fixture. They are generally used at staircase and entrance areas of small-scale projects in our country. These PIR sensors are used to activate the lighting when any person enters the zones and turn off the lighting after the person leaves. There are two different types of fixtures, i.e. LED chipped luminaire and E27 lamp-based luminaire. In this work, detailed optical and electrical analyses have been performed for both types of fixtures. Various types of light sources including halogen and LED bulbs have been used in the analysis of E27 lamp-based fixtures. In addition, the analyses of these light sources have also been performed in detail. As a result, economic performance of the luminaires were compared based on the analyzed data and the most effective luminaire as well as luminaire/bulb configurations were determined
