Lighting plays a key role in our daily life. Sufficient artificial light is too essential in providing illumination for tasks such as reading a book, finding items in a closet, or completing a work project. It can also help people to reduce strain on the eyes and to improve focus and concentration. Designers are increasingly turning to lighting to create a warm, inviting atmosphere in both residential and commercial spaces. By precisely setting the composition and brightness of each room, architects and interior designers can take advantage of the psychological effects of light to influence user experience. As technology progress, the possibilities for manipulating light to create dramatic effects have become more accessible. Through the use of dimmers and LED lights, a range of moods and tones can be created. Smart lights that are connected directly to devices such as phones and tablets are becoming increasingly popular, allowing users to control lights in multiple locations from a single device. The potential of lighting as a design element is nearly endless and will only continue to grow with innovation in technology. With the advancements in lighting technology, interior designers can create vibrant and atmospheric environments, while reducing energy bills.
