Lighting is considered a fundamental element in architecture and is one of the most important parts in any interior design. It not only plays an important role in creating a particular atmosphere in a room, but it can also be used to add functionality, in the form of task lighting, and can be used to make a space appear larger or more intimate. Good lighting can transform any room, creating the right ambience and creating a strong visual impact. Varied lighting solutions can be used to create different effects. For example, yellow-tinted lights can be used to create a cosy atmosphere, while cool blue lighting can be used to create an airy atmosphere. The success of any lighting scheme depends on combining different elements, like light fittings, lighting sources, and controls. The main types of lighting in interior design are natural, task, and ambient lighting. Natural lighting is the most desirable, since it can be used to create bright and airy spaces. Task lighting adds functionality to a room, and can be achieved by adding reading lamps in living rooms or working spaces, or through adding down lighting in kitchens and bathrooms. Ambient lighting is used to create atmosphere, and can be achieved through adding floor lamps, wall lights, and LED lights. Lighting is an essential part of interior design. With the right types of lighting, it is possible to create different ambiences and to improve the appearance and functionality of any space.
