Lighting has long been an important part of architecture and the built environment. It is used to create atmosphere and mood, enhance security, aid visibility, and support other activities. Natural lighting is the oldest and most common type of lighting used since historic times. Natural light is the light we get from the sun. Its intensity depends on the strength of sunlight, the season, and the geographic location. Over time, the sun's intensity changed due to the Earth's rotation and the movement of the moon, resulting in daily and seasonal variations in daylight. Architects design buildings to take advantage of natural light, using large windows and skylights to capture light from the sun. Artificial lighting has come a long way since its invention. It is now used in almost all designs. It is used to supplement daylight and create various moods and ambiances within a space. Artificial light can be used to create a dramatic atmosphere, illuminate a work environment, or provide a safe living environment. Today, there are a wide variety of lighting technologies including incandescent, fluorescent, LED, and HID. Each species of lighting has its own characteristics and benefits. For example, LED lighting is energy-efficient and long-lasting, while HID lighting is ideal for outdoor lighting. Lighting is at the heart of good design and is an integral part of the built environment. Architects and designers must consider lighting when creating a space because it can achieve both functional and aesthetic goals. No matter the type of lighting, it can be used to enhance the beauty and functionality of any space.
