Lighting plays an essential role in life. Not only does it bring brightness to our lives, it can also help us to better understand our environment. Lighting not only helps us to see during the day and night, but also adds a great deal of beauty and atmosphere to our surroundings. In the day, the sun's light brings us warmth and vitality. In the evening, artificial lighting of all kinds can create a cozy atmosphere for us as well. The use of lighting in residential, commercial, and industrial settings can drastically change the look and feel of a space. Lighting technology has come a long way in recent years, training us to think more consciously about the types of lighting that we use in our day to day lives. This development has led to a dramatic increase in energy efficiency. LEDs have revolutionized the way we provide lighting, both indoors and outdoors. Their lower energy consumption and longer lifespan helps us to save money and time. In short, good lighting design looks to balance the practical with the pleasing. It is beneficial to strive for a mixture of natural and artificial lighting that is both visually appealing and strategically positioned to create a space that allows us to be productive, comfortable, and happy.
