First, define the room you will ceiling light parts. We recommend that you draw on a folio an approximate plan of it: the placement of the furniture (in the case that it is already a furnished room) and the position of the windows. Let's say for example a living room. In a room like this you can define different environments: perhaps a corner of reading and relaxation with an armchair, another meeting and conversation around the table, another storage and organization where the bookstore is and another to watch TV.
Remember that there is no single idea of ​​illumination and that the same ceiling light parts can serve to illuminate at different times. Before putting yourself to decorate with lights, it is important that you know the different types of lamps and existing light sources. A lamp can emit light in two different ways: directional or diffuse.
The directional light comes from lamps that emit a beam of light concentrated on a concrete surface. These ceiling light parts usually have opaque and reflective screens, which causes the light to concentrate. The diffuse light on the contrary spreads of uniform form by all the room, creating a bubble of light that produces smooth contrasts in the little illuminated zones. It is achieved with lamps with translucent screens, glass, paper or fabric.
