Method of images and influence of lighting radiation intensity on student learning effectivity in hygiene and ergonomics of education

Abstract

42 years ago, studying digital-light-color analogies in combination of mechanoreceptors, we created Method of teaching any subject, based on Images and Patterns. In this article we conducted research related to influence of lighting radiation intensity on student learning effectivity. Good ergonomic lighting depends on more than just artificial luminance levels. Our study, conducted at Farber’s Center for Academic Success, Inc and Saratoga Waldorf School shows how much the general luminance in school buildings depend on natural light. Luckily the buildings have plenty of windows in each room and receive plenty of natural light. The reliance of a day school like Farber’s Center for Academic Success and Saratoga Waldorf School on natural light offer reasons to research the design possibilities for an optimum use of daylight. However, a classroom is a difficult space to light with daylight, because of the depth of the classroom and the different tasks, which must be performed in it. By combining a good daylight design with a good electric lighting concept student can enjoy better lighting and the energy for electric lighting can be reduced substantially. Incandescent lights appear to be the lighting of choice for the majority of students. Incandescent light bulbs of 100Watts providing 1600 lumens can be the ideal lighting device in school. The light is closest to natural light and is the most preferred by the majority of people. However due to energy consumption reasons, incandescent light bulbs of 60W are used in general, but they don’t provide enough luminance especially in the evening. LEDs provide much higher light output on the same input power as comparable incandescent or fluorescent sources, because of their high efficiencies. This is also because the light emitted from the LED is naturally directional, and in almost all applications less light is lost in the fixture compared to traditional light sources. LEDs light represent a good compromise between quality of light and energy efficiency. Also, the price of LED lights is decreasing steadily while quality is increasing, including the possibility of controlling each LED light bulb by remote control allowing the lighting to be dimmable. The fluorescent lights appear to be the worst choice for the school buildings despite the fact that majority of schools in USA use them to save electrical energy. Now that the price of LED is decreasing steadily and you can find affordable LED light bulbs on the market even the claim of energy efficiency is gone for the fluorescent lights. This study has taken place in three schools over the period of 5 years. It has involved hundreds of hours of work, planning, writing, changing light bulbs in the classrooms, ordering supplies, taking surveys, administering tests, interpreting data.
