Lighting research is a field that studies the effects of light on humans and the environment, and explores ways to use light effectively and efficiently in various applications such as architecture, urban planning, interior design, and health care. This research area seeks to understand how lighting can affect people's mood, behavior, productivity, and health, as well as how different lighting technologies and designs can minimize energy consumption and reduce environmental impact. Lighting research also encompasses the study of light pollution, which refers to the excessive or misdirected artificial light that can cause negative effects on wildlife, ecosystems, and human well-being. Overall, lighting research aims to improve the quality of light in our built environment and promote sustainable lighting practices.
