Under normal circumstances, classroom lighting in the campus needs to be equipped with classroom lights and blackboard lights. Is the blackboard light a classroom light? What is the difference between classroom lamp and blackboard lamp?

Generally speaking, classroom lights also include eye protection blackboard lights. However, in the campus lighting design, the classroom lamp only refers to the lamp used to illuminate the student table and podium, excluding the blackboard lamp, because the blackboard lamp needs another light source. The lighting in the classroom is generally educational led eye protection lamp. The lampshade has grid anti glare type and micro rhombic anti glare type, with large luminous area and symmetrical and uniform light.

The blackboard lighting should use the blackboard lamp with asymmetric strong light distribution. Because the blackboard lamp cannot be placed in the vertical center of the blackboard, it can only be placed above the blackboard. In order to ensure the uniform illumination of the blackboard, only the blackboard lamp with asymmetric strong light distribution can control the uniform illumination of the whole blackboard without dark angle.

Adjust the irradiation angle according to the position of the blackboard to prevent glare, so that students can read blackboard books more clearly and take better care of the eyesight health of teachers in the podium area, so as not to cause eye fatigue and make teachers work more at ease.
