Zusammenfassung:	The utility model provides a LED anti -dazzle blackboard lamp, relates to a blackboard lamp. The utility model discloses a solve that present LED classroom lamp direction of light controllability is strong, the illumination intensity degree of consistency is poor, can not all shine blackboard, some lightmap dazzle light to student's production problem because of light. The utility model discloses the blackboard lamp includes casing 1, arc -shaped lampshade 2, lamp area mounting 3 and LED lamp area 4. The utility model discloses blackboard lamp intensity of illumination is average, and the direction controllability is strong, and the blackboard is seen from the students' affairs division moreover to the light high -usage, can not produce and dazzle light, the lamp area mounting capacity of heat transmission of aluminium system is strong, does benefit to the heat dissipation. The utility model is suitable for a blackboard illumination. 种LED防眩光黑板灯，涉及种黑板灯。本实用新型为了解决现有的LED教室灯灯光的方向可控性不强、光照强度均匀度差、因光线不能全部照射到黑板、部分光线照射到
