Zusammenfassung:	The invention discloses a blackboard lamp. The blackboard lamp comprises a lamp shell, a diffuse reflection cover arranged in the lamp shell, an aluminum substrate provided with a lamp bead, a convexlens piece and a concave lens piece; a light output port is formed in the lamp shell in the length direction of the lamp shell; the convex lens piece is arranged on the inner side of the light outletport in the length direction of the lamp shell and the convex surface of the convex lens piece faces the lamp shell; the concave lens piece is arranged on the outer side of the light outlet port in the length direction of the lamp shell, the concave surface of the concave lens piece faces the lamp shell; and the light emitted by the lamp bead passes through the convex lens piece and the concave lens piece in sequence after being reflected by the diffuse reflection cover. The blackboard lamp has the advantages that the diffusely reflected light sequentially passes through the convex lens pieceand the concave lens piece
