The architecture should be considered in light of modern neuroscience research. The powerful influence of light on brain neurotransmitters adjust the attention, mood and behavior and affect safety and work performance.
Influence of lighting in the workplace.
The city dwellers spend up to 80% of the time in closed environments, housing, transportation or work, some opaque enclosures with little or no sunlight. The optics have long known that light affects the visual acuity and color perception. Today the state of neuroscience research to suggest that light is Biodine &nt.
light call light to the spectrum of electromagnetic radiation as perceived by the human. Includes infrared light, which we recognize as heat, the entire visible spectrum, with the seven colors of the rainbow and ultraviolet rays, responsible among other beneficial effects of tanning. Visible radiation, between 400 and 720 nm (1 nm = 1x10-9 m), are particularly perceived by humans because of these sensors are wonderful eyes. Our retina is thousands of times more sensitive than the skin sensors, which also responds to the invisible bands of light, infrared and ultraviolet light.
minimum lighting intensity We need a bright light, minimum intensity between 800 and 1000 lux, which tells the nervous system that it is day, and awakens us mood, without chemical stimuli such as coffee or snuff. Photobiology tells us that the perception of bright light in the pineal gland, inhibits the secretion of melatonin, the sleep hormone, and provides the brain serotonin, the hormone activity. Generally
minimum illumination is calculated to allow readability. In the amblowing are common work intensities from 100 to 200 lux in hallways, and 300 to 500 lux in offices. Inadequate lighting levels can not overcome the drowsiness and be mentally awake and alert.
contrast abroad are from 10,000 lux on a cloudy day, up to 150,000 lux at midday in midsummer. We all perceive the injection of vital energy that is captured to go outside when the sun's rays bathe our skin. The sun looking for something more than a fashionable tan.
reactor, magnetic and stress batteries have a frequency fluorescentence of 50 Hz is blinking press stress induces brain waves, Beta waves, in addition to physical fatigue, headaches and eyestrain. Stress causes an excessive secretion of cortisol in the brain, killing millions of neurons. The reactors also produce radio interference, disrupting telecommunications and computer systems, and cause major pollution electromagnetic (elektrosmog), which affects health.
The high-frequency electronic ballasts, which vibrate at 20,000 Hz, eliminate eye fatigue and stress to prevent flickering of the tube, since it fails to shut down completely.They also produce an instant-on, to dispense with primers and capacitors, save energy, extend the life of the tubes and remove elektrosmog.
Color and full spectrum lighting.
The lighting used since Edison's incandescent lamp. The filament emits a warm light with a color profile which dominate the yellow-orange-red, with no high-frequency tones, green, blue and violet. They are also both traditional incandescent standard lamps, such as sodium vapor lamps and mercury or modern dichroic andhalogen.
fluorescent light normally used, gives a light cold, bluish-green cast, is deficient in the blue-violet and orange-red. The use of fluorescent tubes is widespread in energy savings, the predominance of fluorescent batteries work environment is one of the sick building illnesses. There are different shades, cool white, warm white, deluxe, which improve the visual impact, but do not have a full color spectrum. Instead
modern fluorescent lamps FULLSPECTRUM produce a pure white light, with all the rainbow colors, similar to sunlight, which permitsulan activity. By contrast, in the absence of light stimuli, increases melatonin which induces sleep. The lack of natural light rhythm, melatonin cycle alters serotonin, causing morning drowsiness and insomnia at night. 30% of world population, mostly in developed countries suffers from chronic insomnia.
The amount of light affects us as shown by the SAD. At the beginning of winter, almost like a hibernation, the TAE produces apathy, excessive appetite and depression because of low winter light, was discovered by Dr. Rosenthal in 1981. In winter there is less natural light, due to cold, we m & aacutcircadian rhythm sleep, including delayed sleep type, jet-lag and shift caused by the shift.
Research conducted since 1990 by neuroscientist Roa, in the R & D colorsystem, confirmed that a better use of light in the blue-violet and orange-red. Stimuli with full spectrum lighting and color filters allow an improvement of distance visual acuity, less diopters in 95% of cases, and better control of the alpha activation cycle, with improvement of cognitive-perceptual process, achieving higher academic performance and work.
These constants psychobiologicalas alertness and attention, can be evaluated quantitatively by visual test, noninvasive, determining an individual's work performance.
Architecture
light design environment must be considered by both the cycle time and the amount of light, the light biodynamic, according to environment and climate. But it must also studied the quality of that light, especially its color, and also the contrast and spatial distribution, according to ergonomics, as the use of each space.
Most architects and interior designers do not consider sufficiently the impact that
