Illumination systems are setups designed to provide light in various environments, enhancing visibility and safety. These systems can include natural light sources, like sunlight, as well as artificial sources such as LEDs, fluorescent lamps, and incandescent bulbs. They are commonly used in homes, offices, and public spaces to create comfortable and functional lighting. The design of illumination systems often considers factors like brightness, color temperature, and energy efficiency. Properly designed systems can improve mood and productivity while reducing energy consumption. Advances in technology have led to smart lighting solutions that can be controlled remotely, further optimizing illumination for different needs.
