Two-story building. Is the corridor light on the first floor or the second floor?

Of course, it belongs to both the first floor and the second floor, not to use the first floor or the second floor separately.

Extended data:

Installing lamps in the corridor is not only for safety, but also for guiding the direction, so that we can find our room quickly and provide convenience for our life. Corridor lighting generally uses downlights, which can be used in lamp troughs, wall lamps and so on. What we need to pay attention to is that if the corridor is long, do not install lamps at equal intervals, but install them near the entrance of the room, which will make the position of the room more obvious. When installing a wall lamp on the wall, pay attention to the position where the lamp is installed, and don't hinder walking or block children in the room; If it is installed near the door, it can be flush with the upper door frame; If the wall lamp is installed in a narrow corridor, use a smaller diameter. LED downlights shine evenly and can be used to create a warm and romantic atmosphere. When choosing corridor lighting, we should pay attention to the ratio of the distance and height of lamps to avoid uneven illumination and light spots in corridor lighting. Using LED strip, a lamp that can be hidden in the ceiling continuously, together with an extended lamp trough, can provide us with a soft scattering light source, and it also has a good guiding function.
