Lighting is an essential aspect of modern life. It is used in virtually all aspects of life ranging from providing light to see when dark outside, to adding atmosphere and warmth for events, homes, and workplaces. Advancements in lighting technologies have brought improved life quality for many. LED lights, for example, now offer more efficient energy solutions, saving energy needs for residents and businesses alike. LED lights are also capable of emitting different colours and differing intensities and light distribution depending on the application. Modern lighting, in the form of design can make a massive difference to an interior, setting the tone and atmosphere in a room, perfect for relaxation, concentration, and enjoyment. While design lighting comes at a cost, when compared with other forms, the general aesthetic of the room is improved and the sense of well-being increased. Lighting technology is also being used in other industries, such as automotive technology. Intelligent lighting solutions, such as adaptive headlights, which adjust the beam pattern in response to driving conditions, are available in many new cars, offering safer journeys and protecting drivers and passengers alike. Lighting is here to stay and advances in the field continue to benefit people in all walks of life.
