The room doesn't have much natural light and doesn't have to worry too much. In fact, no window means there will be a more dynamic lighting design, but if you are forced to do natural light, it will lead to sharp results. For many cellars and basements, there is little or no natural light available, and the corridors may lack sunlight.
First, take advantage of any natural light you can use. In a real windowless room you can also let the sun enter through the light pipe and let the refracted light enter a room. In addition, the skylight may be an option. If you have a basement, these two solutions take the stairs into consideration as a potential light. First, remove any wall blocks and whiten the walls and stairs so that any natural light that illuminates them will be reflected to the room below. Spotlights are a great way to illuminate in a room without windows. In the wine cellar or game room, you can use it to directly shine on the area you are interested in. If you think a room without windows is not for you, you can create a fake face. Through the fake wall, with LED lights, you can deceive the eyes and let it feel natural light.
