Beschreibung
Zusammenfassung:	The invention belongs to the technical field of blackboard lamps, and particularly relates to a novel blackboard lamp. The novel blackboard lamp comprises a sectional material body, wherein a first lamp strip is transversely arranged at the lower end of the sectional material body, the upper side wall of the first lamp strip is fixedly connected with the lower side wall of the sectional material body, and single lenses which are evenly distributed are arranged at the lower end of the first lamp strip. According to the invention, the uniformity of the blackboard lamp is improved by 90% or more and a light energy utilization rate is improved since the first lamp strip are arranged in the single lenses which are evenly distributed; strip-shaped lenses and the single lenses are combined into two rows, the single lens is installed on one row of an LED lamp strip, and the strip-shaped lenses are installed on the other row of an LED lamp strip; the single lenses are designed through a free-form surface technology, s
