Lighting is an important part of our life. It can not only provide us with a source of visibility, but also bring us joy, as it can set a specific atmosphere. Lighting can affect an individuals mood, performance, and overall health. In fact, light has been used in medical treatments for centuries, playing a major role in mental and physical health. Apart from its medical benefits, lighting can also affect how humans perceive a space. Good lighting design within an interior space can change the atmosphere to fit the mood that is desired. A dimly lit room with warm, indirect light implies a lot more than a brightly lit room with crisp, direct light. In the home, lighting can be used to make rooms cozy, comfortable, and inviting. This encourages people to spend more time together in an atmosphere of relaxation. Lighting in public spaces can be used to guide people to a certain area. For example, lighting can be used to direct people to a particular product or business in malls. Finally, lighting can also be used to protect people. Security lights around a home can help deter any unwelcome intruders. In conclusion, lighting is certainly an important part of life. Its ambient nature can be used to modify an atmosphere and even guide people to move in a certain direction.
