Lighting systems are setups designed to provide illumination in various environments, such as homes, offices, and public spaces. They typically consist of light sources, such as LEDs, incandescent bulbs, or fluorescent lights, along with fixtures and controls that manage the light output. These systems can enhance visibility, create ambiance, and improve safety. Modern lighting systems often incorporate technology for energy efficiency and convenience. For example, smart lighting allows users to control brightness and color through mobile apps or voice commands. Additionally, daylight harvesting techniques utilize natural light to reduce energy consumption, making lighting systems more sustainable and cost-effective.
