Energy Efficient Hybrid Led Luminary Illumination Control Mechanisms

Abstract

This work aims to develop LED luminary intensity control (LIC) modules that are energy efficient. In this paper, we propose various modules for varying luminary intensity (LI) based on (i) Zone timer-based intensity control (ZTIC), (ii) ZTIC with motion detection (ZTICMD), (iii) Authorized User LIC (AULIC) (iv) Hybrid mode of LIC (HMLIC), (v) HMLIC with motion detection (HMLICMD) (vi) Intensity control based on priority (ICP). The motion detection mode supports the motion of vehicles with high speed. In hybrid mode, motion detection saves 60–85% of energy and helps to decrease carbon footprints. The modules use simple circuits. These modules use for different outdoor lighting applications.
