With the development of construction, various types of glass lighting roofs are widely used in hotels, stations, airport terminals, shopping malls, exhibition halls, stadiums, museums, hospitals and other buildings. A large area of the patio is covered with a variety of forms and colors of glass lighting, forming an indoor glass roof space that is not affected by the climate.
