Each object absorbs some of the light falling on it and reflects the rest in the environment. The eyes pick up a small part of this reflected light to create visual images. When the light intensity in high glaring eyes with glowing objects (they feel now and it is decreasing, with the look, the amount of light entering the eye). - Level Lighting: A building will be lit properly if the lighting is appropriate to the activity taking place in it. Occasionally, activities may have certain variants, require different lighting, so it is advisable to regulate at will the level of intensity. It is also important considerations other than left-handed.
- Glare: Occurs when there is the presence or absence of different degrees of light simultaneously. A good building design includes proper highlights (natural and artificial), each for itself but also complemented. You can talk about 1) natural lighting and 2) artificial.
1) natural lighting. The sun is the source of light during the day to exert an influence on the minds of the people providing both physical and psychological. However, most visual tasks sensitive (sewing, reading, etc.) are impossible to carry out direct sunlight. In turn, warmer periods the heat inside the buildings is very annoying and the bleaching effect of sun is one of the drawbacks involved. To block or filter direct light reflected, leaving a softer vegetables can be used (trees, vines, etc..) Awnings, shutters of all types, blinds, canopies, curtains, etc.
As mentioned above (item 1) south receives almost no direct sunlight so a south side window ensure indirect light without significant heat contribution. In these cases where the sun does not penetrate directly into the room, the amount of light at a point of it depends on the total area of \u200b\u200bsky can be seen from that point through the windows and of course the brightness of that portion of the sky. That is, the closer the window paid more light ceiling. In turn, the room high and low depth will be much brighter than one whose space is narrow and deep. In the latter case, it may be advisable to balance the lighting setting windows on a second side of the room or a skylight.
By placing windows must take certain precautions for the activity to be held in the room. For example if you build a room class probably a window next to the board will give a luminosity that is likely to leave unusable. The natural light illumination allows a nice transition between indoors and outdoors. Its main drawback is the inconsistency (at night). Artificial electric light is instantaneous and constant use, so that both types of lighting when the artificial supplement is used at night.
2) artificial lighting. - Luminous Flux: The light energy per unit time. The unit of measure called the lumen.
- Lighting: The ratio between the luminous flux receiving a surface and its extension.
To get an idea provides thirteen candles lumens, a 100-watt incandescent bulb 1200 lumens and a high-powered fluorescent tube 80 watt 4500 lumens.
tubes convey an interesting light bulbs, similar to that of
fire. A room takes on a nice light for this type of lighting, especially if the walls with warm colors and materials. It is widely used in homes, shops, restaurants and churches among others. Fluorescent lighting is used more in commercial, industrial and institutional.
is very important to place the light source outside the field of view normal people using the site, and try to get a proper brightness to the task to develop there.
The color of the room or does not contribute to the light and prevent or no glare. Light colors are more reflective than dark ones absorb more light.
