Lighting, or illumination, is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting is the practice of placing windows or other openings and reflective surfaces so that during the day natural light provides effective internal lighting. The technique of lighting is used within stage lighting, cinema and video production, and also in photographic studios where backgrounds and subjects can be lit. Early days of film production were pioneered using sunlight, Reflector lamps, and various oil & gas lights such as arc-lamps which produced very bright, but quite soft light. Lighting technology has evolved over time and different types of artificial lighting have been invented. Most common types of lighting used in residential homes and commercial spaces include incandescent lighting, fluorescent lighting, and halogen lighting. With the arrival of LED lighting, there has been a dramatic shift in lighting technology. LED lighting is more energy efficient than other lighting types and is also better for the environment. Lighting has always been an essential part of interior design and home decoration. Different types of lighting can be used for different purposes and different rooms in a home. For example, task lighting is important for work areas such as the kitchen, bathrooms or even a home office. However, for a living room or a bedroom ambiance lighting is recommended for creating a relaxing atmosphere. Lighting also plays an important role in the events industry. Events such as concerts, live shows, and weddings require proper illumination to create an atmosphere that will be remembered. Lighting for events can be used as a tool to create different emotions and feelings to create more excitement and energy. In conclusion, lighting is an important tool used to create beautiful atmospheres and a comfortable environment. With the advancements in lighting technology, the possibilities are endless.
