Lighting is an indispensable part of our lives. Whether it is for practical or aesthetic purposes, artificial lighting has become a staple of modern life. In terms of practicality, lighting goes beyond just illuminating our homes and streets. Public lighting is used to indicate pedestrian pathways, guide drivers on roads/highways, and keep our cities safe. Proper lighting is also essential in industrial areas where operations must be accomplished in the dark, in order to protect the workers eyesight. In addition, lighting can also be used for aesthetic purposes. Whether it is for a wedding, a stage performance, or a club party, lighting can transform any dull atmosphere into a lively and vibrant space. Architectural lighting can be used to bring focus to certain buildings and landmarks, creating a unique ambiance. Lighting also has a Psychological impact on us. Bad lighting can induce feelings of anxiety and depression in certain individuals, while good lighting can improve mood and productivity. In conclusion, lighting is an important aspect of modern life. It not only helps us to navigate through various environments, but can also be used to transform any dull space into an entertaining one.
