The blackboard lamp should be a special lamp with asymmetric light intensity that casts light in the direction of the blackboard
Outstanding educational lighting environment requires the selection of high-quality educational lighting fixtures. In educational lighting, blackboard lighting is the key and difficult point, and the blackboard bears the burden of transferring knowledge points. On campus, the utilization rate of blackboards is very high. We should deal with the needs of blackboard lighting from the perspectives of teachers and students. Classroom blackboard lights carry many things, involving all aspects, such as students, youth's vision protection, the improvement of the learning environment; campus, energy saving and electricity saving, saving the cost of product replacement, etc., these are all very important, therefore The selection of classroom lights and blackboard lights must be professional. At present, many campuses have chosen the lamps and lanterns of the education lighting of the middle school to light up the classrooms, and have achieved good results. Blackboard lighting design The illuminance of the blackboard should not be less than 500lx, and the uniformity of the illuminance on the blackboard should not be less than 0.7. A distribution box with a certain capacity can be installed on the side of the blackboard for classroom lighting and power supply for strong and weak electrical equipment sockets. The blackboard light switch should be set independently. Students look at the blackboard with a low angle of view. The blackboard lighting should not cause reflected glare or direct glare to students. Teachers should not be affected by the direct glare of the blackboard lamp when writing on the blackboard or facing students. Therefore, the blackboard lamp should be a special lamp with asymmetrical intensity that casts light in the direction of the blackboard.
