Illumination Engineering is the science and art of designing lighting systems to enhance visibility and aesthetics in various environments. It involves understanding how light interacts with surfaces and how it affects human perception and comfort. Professionals in this field focus on creating effective lighting solutions for spaces like homes, offices, and public areas. This discipline encompasses various aspects, including the selection of appropriate light sources, such as LEDs and fluorescent lamps, and the use of lighting controls to optimize energy efficiency. Illumination Engineers also consider factors like color temperature and luminance to ensure that lighting meets both functional and aesthetic needs.
