Lighting is the use of light to brighten our lives. It is used in architectural structures and artwork designed to create or enhance a certain atmosphere. Lighting can be used for commercial and residential purposes, and it also has a variety of applications in industrial, military, medical and scientific fields. Indoor lighting can be divided into two categories: natural and artificial. Natural lighting is light from sources such as the sun, fire, or candle. Artificial lighting is light generated by electric bulbs, LEDs, and other sources. Each type has unique features and characteristics, and can be used in various ways to create the desired effect. Task lighting is used to provide light to specific objects or areas. It is usually focused on a workspace or other area where specific tasks are performed. This type of lighting is often found in home and commercial settings. Accent lighting is used to emphasize certain points in a space. It is used to bring focus to a specific piece of art, furniture, or other feature. It can also be used for decorative purposes. General lighting, also known as ambient lighting, is used to fill an entire space with a uniform light. This lighting is used to provide a comfortable environment and is often found in living rooms, bedrooms, and dining areas. Lighting can also be used for security purposes. Motion lights are becoming increasingly popular for outdoor settings, and they turn on when they sense movement. They act as a deterrent and help to deter intruders. In conclusion, lighting is a necessary part of our lives. It is used for a variety of purposes, ranging from providing us with task and accent lighting, to providing us with general lighting, to providing us with security. Lighting can also be used to create an atmosphere or to make a space more beautiful.
