Interior lighting Part II




Light for reading, knitting, embroidery and other occupations and activities

It can be achieved by hanging lamp, wall lamp with extended arm, as light is brought to the middle of the group or through a floor lamp. In the dining area typically are placed hanging lamps - single or in groups over the table. In this situation the table must be fully lit and the light source must be completely covered so it doesn't irritate the human eye. For writing in the workplace must be provided two types of lighting - diffuse and concentrated. In such combined illumination we must avoid the sharp contrast between the brightly-lit work area and the rest, sunk in the darkness of the room area.
Lighting at the workplace can be implemented in several ways:
  •  by standing lamp with two light sources, as the one is directed to a wall or ceiling of the room in which we work;
  •  by a light source focused at the workplace;
  •  by table lamps with the same options as in the first case;
  •  by standing or table lamps with focused light directed to spots in cases where it is used for general illumination of the room.


   
 Lighting for the work area can be sufficient with lamp of 60 watts. Dazzling light reflected from the white surface of paper, will be falling straight into the eyes, this is acting very adversely to the vision. 
In addition to the bedroom lighting it is necessary for us to provide local illumination - over the beds and dressing table. The local illumination over the beds is very important. It is implemented in different ways: with lamps placed on bedside tables, or lamps attached to the wall above the bed. It is best bedside lamps to be equipped with lampshades that provide focused and concentrated light that help to not interfere with other occupants in the room and leave them to sleep without bothering them. The light source should be with a normal intensity, i.e. one that is "whatever is necessary for reading". It is harmful for the eyes when we use lamps with small bulbs.
      Another important point with local lighting in the bedroom is the dressing table. The main purpose of the lighting here is the light on the mirror. Light sources placed on both sides of the mirror must have a soft diffused light and must be located at head height. We mustn’t forget and the possibility of lightening for reading, knitting, embroidery and other occupations and activities. It can be done by hanging lamp, wall lamp with extended arm, as the light is brought to the middle of the group or through a floor lamp. In the dining area are usually placed hanging lamps - single or in groups over the table. In this situation the table must be fully lit and the light source has to be completely closed. 
      The number and location of lighting fixtures depends from the shape of the table. In round or square table they are grouped around the center, and when the table is rectangular or oval they are placed linear. For lighting in the workplace of the student is valid everything we said for the daily workplace. In addition to the lighting of a kitchen we need to add and local lighting over the work area. If you provide only general lighting, shadow of the worker will fall on the desktop and will interfere his work. Light sources are located so that the light beam is directed on the desktop, but does not fall directly into the eyes of the worker.
