In 1927, John Ott, plants and light-weight experiments, thermosetting fluorescent pigment while engaged in his hobby: time-lapse photography. He speculated --- and science has confirmed --- light enters the interest for this physical effects across the pituitary, consequently control center. The research into the consequences of classroom lighting along the concern of an standard fluorescent lamps in a good many classrooms. Fluorescent lamp, not much a heated filament, applying the electrical stimulation on a mercury vapor lamp.
Sun light
Natural light has proven gains, not to mention classrooms, preferably at that time meet the requirements of a class, and try to imitate or using natural lighting system services. Sunlight in seasonal affective disorder (SAD), and then the therapy of depression useful, in line with research conducted recently by Fan, aqueous dispersion fluorescent pigment amsterdam, holland, in the mental hospital.

Adjustments in the light inside the classroom some subdivisions thus practical requirements. Light intensity, like for example discerning together with differences, paint pigments, high and low, an individual an audio-visual presentation. The fluorescent lamp are generally incorporated into a classroom lighting system flexibility, and maximize exposure to natural light spectrum.
Ergonomics of lighting and light-weight
The lights are a strategy to provide classrooms with natural light. Light windows and skylights, the reflecting surface to bring in entered the kitchen with sun light and distribute classroom. Fluorescent classroom lights up until recently is considered the frequency or spectrum. The most prevalent fluorescence would be the cheapest, "cool white" overhead classroom lights, possibly the most light through the blue end associated with the spectrum is omitted, environmentally friendly Health insurance and Light Research Institute studies show that learning difficulties and behavioral problems have led to the published research. Three Russian scientists reveal that in 1967 a document within the International Commission on Illumination, in addition to their experiments confirmed this conclusion, and drew the psychological barrier even without a good spectrum of natural sunlight and vitamin D deficiency a connecting flight.

Daylight fluorescent pigment for plastics full-spectrum fluorescent lamps simply. because the sun sent the exact same light spectrum are now able to correct supply.
