How to choose the best classroom blackboard lamp?
With the increase in the use of electronic products by teenagers, classroom blackboard lights have appeared on the market in order to protect their eyesight. We may think that classroom blackboard lights can only serve as lighting, but they are not. A good classroom blackboard lamp should have no blue light damage, no stroboscopic light, uniform light illumination, and soft color temperature. To a certain extent, it can alleviate the fatigue of the students’ long-term use of the eyes, and requires high color rendering. Let the children clearly see the words on the blackboard.
Using the blackboard light can prevent ultraviolet rays and prevent dizziness. In order for students to study safely and effectively in the classroom, the quality of the lights must be required. Its lighting allows students to clearly understand the glare-free billboards, which is in line with the principles of optics. It is also easy to assemble, disassemble and clean. In fact, it uses a fully sealed method, and its surface is sealed with high temperature oil, so that scientific treatment can effectively prevent rust, and it can probably avoid the adhesion of mosquitoes and dust. At the same time, it does not contain harmful substances and uses recyclable substances, which will not cause environmental pollution.
Generally, we install classroom blackboard lights according to the asymmetrical strong light distribution characteristics, that is, the lights should be installed parallel to the blackboard, and the parallel distance is generally between 0.7m and 1m. We can avoid the lighting of the blackboard lamp by adjusting the lamp, which makes the glare that students may produce when they sign books. In addition, according to the principle of light reflection, the wattage of the lamp needs to be adjusted properly. If it is too high, it will easily cause glare, not only can not achieve good lighting effects, but also long-term high brightness will make students unable to see clearly .
