1 Natural lighting systems: In these systems, natural light enters the building through windows and other openings in the building. These systems are used to reduce energy consumption and increase the comfort and health of building users.
2 Artificial lighting systems: In these systems, light is supplied to the building through lamps and other light sources, such as projectors. These systems are used in cases where natural light is not enough.
3 Smart lighting systems: In these systems, sensors and electronic circuits are used to control light. In this way, energy consumption is reduced as well as the comfort and health of users is improved.
4 Hidden electric lighting systems: In these systems, lamps and other light sources are installed behind the ceiling or walls to provide light directly, and because the lamps are not visible, the appearance of the building is improved.
5 Direct light lighting systems: In these systems, light is transmitted directly and non-stop through the walls or ceiling into the building. These systems do not require energy consumption to spread light in space.
