Lighting is the science, art, and application to practical use of light. Its an essential component in a well-designed space. Lighting helps to integrate the architecture and modern design to attain directional control, brightness, and color. Lighting technologies can help to create a perfect atmosphere, provide visual comfort, and reduce energy consumption. Lighting has been around since ancient times. Our ancestors used fire for the primary source of outdoor lighting, while inside, candles and oil lamps provided light. Today, many different types of lighting are available, including modern electric lighting, which is considered the most efficient and environmental friendly. Lighting can be categorized into two broad groups - functional lighting and ambient lighting. Functional lighting is used for a specific purpose like to highlight a specific item or function. Ambient lighting is used to create an atmosphere by creating a strong, yet even, illumination. Lighting also plays a major role in interior design-it can make or break a space. While natural lighting is considered the best lighting, artificial lighting can be used to create the desired mood and effect in a room. Combining natural and artificial lighting can be tricky. Each type of lighting casts a different atmosphere and has to be balanced with one another to create the desired effect. Lighting also has environmental implications. It has been estimated that lighting accounts for about 15 percent of the electricity consumed globally. efficient lighting fixtures are being developed and tested to reduce energy consumption. LED lighting is a more sustainable and cost-efficient option than conventional lighting sources. Lighting is often overlooked, but its an important part of any space. Well-thought out lighting design can create the desired atmosphere and reduce energy consumption. With creativity and innovation, lighting can help to create unique and dynamic spaces.
