Can't see the blackboard clearly? How to deal with the reflection and glare of classroom lighting?

According to the survey, some primary and secondary school students in the school reported that there were problems of reflection and glare on the blackboard in the classroom. They could not see clearly in class, and their eyes were sore after a long time. In addition, the lights in the classroom often flicker. Sometimes they are not too bright, or they are replaced only when they are broken.

Myopia mostly occurs in primary and secondary schools. According to the sampling survey, it is found that fluorescent lamps are mainly used in classrooms and blackboard lamps in most schools: there is a large demand for classroom lighting, and the lighting time is long; The most common problems of classroom lamps are that the blackboard will reflect, the light flashes, the light is too dark, etc; Classroom lighting is basically more than 6 hours a day, excluding bad weather. If the classroom eye protection lamp or classroom blackboard lamp fails to meet the requirements, it is easy to cause the above problems and affect the students' visual health.

In view of the uncomfortable glare and reflection caused by the blackboard lamp when students look at the blackboard, it is also found in the research that many classrooms are not equipped with classroom blackboard lamps, or substandard blackboard lamps are installed. In classroom lighting, the blackboard lamp should not only illuminate the blackboard, but also be uniform without glare to protect vision; The illuminance of blackboard lamp shall be more than 500lx, the illuminance uniformity shall be more than 0.8, and there shall be no blue light hazard, stroboscopic and color rendering index of more than 80.

On the other hand, we need to optimize the layout and light distribution of blackboard lamps and improve the quality of blackboard lamps through professional design. At the same time, the school needs to strengthen classroom lighting management, do a good job in the maintenance of lamps and testing classroom lighting indicators.

Therefore, to solve the problems of reflection and glare of classroom lighting, it is recommended that all primary and secondary schools and institutions (including public school classroom lighting, private school classroom lighting, private school classroom lighting, experimental school classroom lighting, educational institutions), classroom lamp OEM and OEM choose "Huahui lighting"!
