In summary, the side window lighting is characterized by the illumination along the depth of the room down quickly, the distribution is very uneven.
Side windows because of simple structure, easy layout, low cost, light has a clear direction, is conducive to the formation of shadows, to watch three-dimensional objects is particularly appropriate, and through it to see the outside world, to expand the field of view, it is very common.
