A well-chosen and placed lighting can give the room a certain mood and style. Thus it is necessary to consider not only aesthetic but also functional purpose of lighting. For a start, consider the basic types of lighting.
Natural lighting – natural lighting created by the sun (it can be as direct sunlight and reflected light) and the light penetrating through the apertures in the outer walling. Premises with constant stay of people should, as a rule, to have natural lighting.
Natural light is distributed into side, top, and combined (upper side), depending on the location of the light apertures in external walls or the roof.
The maximum illumination from the sun – 100000 Lux, minimum is determined at night when the moon is full and level – 0.1 Lux. It is believed that the most favorable illumination of 200 Lux.
Types of home lighting

Artificial lighting – light created by artificial light sources. Can be General, local (local) or a combination.
For General lighting, also called “upper light,” the lamps are placed in the upper area of the room evenly (General even illumination) or with respect to equipment arrangement (General localized lighting). General lighting in the interior unites the whole space together and in their intensity should be close to natural.
Local lighting — the light created by the lamps that concentrate the light flux directly on the illuminated surfaces. Such Islands of light give the room a decorative effect and can be used for zoning.
Combo lighting — lighting in which General illumination to added local. In practice, most often uses this type.
Artificial lighting is also divided into operating, security and emergency.
Work (Task) lighting — provides standardized lighting conditions (luminance, light quality) in premises and places of work. Task lighting should be provided for all rooms of buildings and open spaces, intended for the work, the passage of people and traffic.
Emergency lighting is distributed into safety lighting and evacuation.
Safety lighting — lighting to continue an emergency stop, working light.
