At present, the lighting fixtures and light sources in most classrooms mostly 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 of students to weak light environments can lead to myopia. 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. The Baijian test can conduct classroom illumination and glare tests for schools, and provide classroom lighting test data
Detection range of classroom lighting intensity: Is the lighting and light sources in classrooms, such as indoor lighting illuminance testing, school classroom lighting testing, and library lighting illuminance testing, beneficial for students to use their eyes? Usually, an instrument spectral illuminometer is required to perform lighting detection on all desks and blackboards in the classroom, usually in accordance with the regional standard "Hygienic Standards for Daylighting and Lighting in Primary and Secondary School Classrooms". Illumination intensity is a physical term that refers to the luminous flux of visible light received per unit area. According to the standard, the average illuminance value maintained on the classroom desk should not exceed 3001x (lux), and its illuminance uniformity should not exceed 0.7. The blackboard in the classroom should be equipped with local lighting, with an average illumination level of not * * 5001x (lux) and an illumination uniformity level of not * * 0.8&Nbsp
