In our life has always been using the traditional tungsten filament lamp, fluorescent lamp, energy-saving lamps and other lighting lamps and lanterns, the traditional lighting lamps and lanterns of non-uniform illumination, color is dark, light stroboscope, blu-ray many disadvantages of the harm such as vision and modified in front of the classroom lighting device is for the grille lamp panel, light source using T8 fluorescent tube, recording images not only fuzzy, noise, and image dithering stroboscopic, uneven illumination, the color is dark, light blinking. Hin liberal arts based on the appearance of the classroom, recorded room or reading room in the field after the requirement of professional lighting design, greatly enhance light vertical illuminance, uniformity, color rendering index, glare control, increase the comfort and reduce the students' eyes to the naked eye fatigue, after transforming energy conservation and environmental protection not only, more to protect students' eyesight;
Energy-saving retrofit scheme: according to the "student myopia prevention and control of primary and secondary schools, the school classroom lighting and lighting health standard" design code "and other relevant standards of lighting scheme, completely changed the classroom illumination lamps and lanterns and light biological safety index can't compatible with history, according to the elementary and middle schools classroom lighting and lighting health standard" the instructions of the policy, hin boya standard of middle and primary school classroom lighting engineering and energy saving lighting renovation project provides a feasible solution.
Let students have a bright learning environment, professional r &d and production hin boya classroom and blackboard special lamps and lanterns, can effectively transform the classroom lighting environment, protect students' eyesight.
1 before modification, use naked light, the light point-blank, glare, easy to distract students' attention, severe stroboscopic light, 2 visual stimulation, 3 eyes fatigue, low color rendering index, white light, easy cause visual fatigue, lamps and lanterns is parallel to the board 4, unreasonable layout, evenness is not up to standard.
After transforming 1, using grating against the glare, the light is downy, no glare, does not hurt the eye 2, no stroboscopic, no blue light, comfortable with the eye 3, high color rendering index, color strong reducibility, close to natural light to 4, intensity of illumination uniformity is better than the national standard.
Before reformation, stroboscopic light, glare value > 22, desktop illumination 263 lux.
After modification, downy lamplight, no stroboscopic, glare value < 17, desktop illumination 481 lux, intensity of illumination completely in line with national standards, through professional optics and lighting design, adjust the optical path in space distribution and lighting lamps and lanterns, make the space in the designated area of the uniform distribution of light, not dazzling, thus protecting students' vision, let hin boya lighting light every classroom and illuminate the future of the children."
