Corridor lighting generally adopts wall lamp, downlight or indirect lighting by using light trough. When the corridor is long, do not install lamps equidistantly, but install them near the entrance of the room to make the room look more obvious. Then when installing the wall lamp on the wall, pay attention to the installation position of the lamp, so as not to hinder the walking and the opening and closing of the room door. When installing wall lamps in narrow corridors, please use lamps with smaller diameters. The installation height should be about 2000mm, and it can be flush with the upper door frame when it is installed near the door. Using wall lamps that emit light up and down can not only obtain the effect of intermittent lighting, but also ensure that there is enough light under your feet.
