Abstract

The present invention provides a blackboard lamp. The lamp comprises an optical lens, a light emitting source, an adjustable support, a lamp tile, a bottom shell and a controller, the light emitting source is arranged on the adjustable support, and the adjustable support can adjust the light emitting angle of the light emitting source; the adjustable bracket with the light emitting source is arranged on the lamp tile; the lamp tile is arranged in the bottom shell; the controller is electrically connected with the light emitting source and arranged in the bottom shell. The optical lens is connected with the bottom shell. By arranging the adjustable support, the height of the light emitting source can be adjusted, and by means of the searchlight principle, illumination of the blackboard lampis more evenly focused; the light source of the shadowless lamp is adopted, so that shadows do not appear in a place illuminated by the blackboard lamp, and the effect of protecting eyes is achieved;the optical lens is adopted, so that light transmitted from the optical lens is free of glare, the effect that illumination is more uniform and softer is achieved, and the effect of protecting eyes is achieved.

Description

technical field [0001] The invention relates to the technical field of lamp lighting, in particular to a blackboard lamp. Background technique [0002] Blackboards are widely used in teaching activities and can be used for teachers to write teaching content. The application environment of the blackboard is very diverse. In some environments with poor lighting, the blackboard light will be used to increase the brightness of the blackboard. However, if the light illuminated by the blackboard light on the blackboard is uneven, it will affect the visual conditions of the blackboard content. , and easily cause the viewer's visual fatigue. The standard of blackboard lights is different from that of classroom lights. Blackboard lighting should adopt special blackboard lamps with asymmetric strong light distribution characteristics. Blackboard lights should be installed parallel to the blackboard, with a parallel distance of 0.7m to 1.0m from the blackboard and a distance from the ...
