Description

Technical Field

[0001] The invention relates to the technical field of blackboard lamps, and in particular to a freely assembled blackboard lamp. Background Art

[0002] The blackboard is the most commonly used prop in daily teaching and display activities. The blackboard itself does not emit light, but needs to reflect the light from the environment and lamps before being perceived by the human eye. The application environment of the blackboard is diverse. When the ambient light is poor, a blackboard lamp is needed to compensate. Therefore, the optical design of the blackboard lamp directly affects the uniformity of the blackboard, which in turn affects the observation of the human eye. Especially in classroom teaching, in order to ensure that students can fully and accurately observe the content on the blackboard in a dim environment, it is necessary to use a blackboard lamp for lighting.

[0003] Existing blackboard lamps usually adopt a fixed-specification structure, so that the blackboard lamp can only illuminate a blackboard of a fixed length. The length of the blackboard lamp cannot be adjusted according to the actual length of the blackboard, and the installation height of the blackboard lamp cannot be adjusted quickly and independently, which reduces the lighting effect of the blackboard lamp on the blackboard, which is not conducive to its use in classroom teaching. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a free-assembly blackboard lamp that can flexibly adjust the length of the blackboard lamp and realize free adjustment of the installation height of the blackboard lamp.
