Lighting has been an integral part of architecture for as long as there has been building. It serves both a functional and aesthetic purpose, illuminating the darkness and providing a sense of safety while adding a dramatic visual element to the built environment. Lighting has been used in architecture for centuries—from the fire-lit torches of ancient Rome to the glow of the Eiffel Tower. Even in modern times, lighting continues to drive architectural innovation, from creative lighting choreography along an urban facade to smartly-designed fixtures that optimize energy efficiency. There are many types of lighting in modern architecture, including interior and exterior, natural and artificial. Interior lighting includes ambient lighting, task lighting, decorative lighting, and accent lighting, all of which can be used to create a specific mood or draw attention to certain features. Exterior lighting can provide a sense of security and also be used to show off the exterior design of a building. Natural lighting can dramatically reduce energy costs while providing a source of vitamin D. Artificial lighting, on the other hand, can be used to create greater contrast or highlight particular architectural elements. No matter the type of lighting used, lighting in architecture adds the perfect finishing touch, allowing buildings to come to life after the sun goes down. Architects must carefully consider the type of lighting that best suits their design, ensuring it not only provides sufficient illumination but also reflects the intent and style of the architecture.
