Primary and secondary school classroom lighting testing units, professional schools, and other public places' indoor lighting illuminance testing institutions have issued accurate testing data reports, providing professional lighting testing data for the improvement of classroom lighting systems. With professional data as a basis, the installation of classroom lighting systems can achieve more scientific and safe implementation At present, most classroom lighting fixtures and light sources use double ended fluorescent tubes, which can basically meet the requirements of classroom lighting. However, with the aging of fluorescent lamp ballasts and light sources, the light output efficiency will decrease, leading to a decrease in classroom illumination. Long term exposure to weak light environments can easily lead to myopia for students. In addition, some old-fashioned classroom lighting designs have exposed fluorescent tubes, which can cause strong glare when projected onto the classroom blackboard and desks, causing fatigue and discomfort for teachers and students in their teaching and learning Detection scope: indoor lighting illuminance detection, school classroom lighting detection, library lighting illuminance detection, etc

Test content: Is the lighting and light sources in the classroom beneficial for students' eye safety? Professional instruments such as spectrophotometers are usually required to perform lighting testing on all desks and blackboards in the classroom. Typically, according to the national standard "Hygienic Standards for Daylighting and Lighting in Primary and Secondary School Classrooms", light intensity is a physical term that refers to the luminous flux of visible light received per unit area. According to regulations, the average illuminance value maintained on the classroom desk should not be less than 3001x (lux), and its illuminance uniformity should not be less than 0.7. The blackboard in the classroom should be equipped with local lighting, which should maintain an average illuminance of not less than 5001x (lux) and an illuminance uniformity of not less than 0.8. Relevant testing reference standards: According to the "Methods for Measuring Illumination in Public Places" (GB/T18204.21-2000) and "Indoor Illumination Measurement Methods" (GB/T5700-2008), the artificial lighting illuminance in public places and various indoor lighting in buildings are measured.
