Before modification

After transforming

Before modification tubes are used by several indoor fluorescent lamp bracket, installation position is not reasonable and the serious shortage of quantity, cause indoor illumination, color rendering index, color temperature, uniformity and other parameters do not meet national standards, and indoor glare, blu-ray and stroboscopic damage is serious, the desk surface and blackboard panel illumination dim, the serious influence students' vision. In this scenario for a long time to read and study, easy to lead to students myopia. After the selection and renovation of classroom lamps and lanterns designed by Pan American Professional, it not only meets the illumination and uniformity requirements stipulated in the standard, but also solves the problems of stroboscope and comfort level from the perspective of health care, so as to protect the visual health of teachers and students in an all-round way. Attached is the conformance report (see below) entrusted by the national quality inspection accreditation institution for the renovation project.
