Background technique

Solar energy is a new energy source with no pollution and abundant reserves. It has been widely used in industrial and residential areas, such as low-rise houses in underground garages, basements, tunnels, mines, closed buildings or dense buildings. In places where sunlight cannot be directly irradiated, solar lighting systems are often used to gather solar energy for lighting, heating or power generation. Existing solar daylighting systems generally collect sunlight through a daylighting panel composed of plane reflectors. Although the plane reflector has a high reflectivity, it has no light-gathering ability. It needs to use multiple reflectors to reflect sunlight to the basement. In buildings and other places, it may be necessary to make plane mirrors into a specific shape or place them in a specific array, so that the reflected sunlight can easily converge. However, this kind of lighting system often takes up a large area, complex devices, and low lighting efficiency.
