Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, in particular to a lighting lamp for classrooms. Background Art

[0002] Classroom lighting plays a key role in the teaching environment. It boasts numerous features, including high light uniformity, ensuring optimal brightness in every corner of the classroom and preventing uneven brightness that can affect students' vision and learning. Its excellent color rendering index accurately restores the original colors of objects, enabling students to clearly distinguish the colors of books and teaching aids. In terms of lighting intensity, it strictly adheres to national standards, providing sufficient and comfortable light to meet the needs of various daily teaching scenarios, such as writing, viewing the blackboard, and conducting experiments.

[0003] For example, the Chinese patent publication number CN217209123U discloses an adjustable height classroom smart lamp, which belongs to the field of lighting fixture technology, including a lampshade, a lamp strip, a fixing part, a lamp arm bracket, a support rod, a ceiling rod and a ceiling mounting part. A ceiling rod is fixed to the bottom of the ceiling mounting part, and a support rod is installed at the bottom of the ceiling rod. Lamp arm brackets are arranged on both sides of the support rod. A fixing part is arranged under the lamp arm bracket, and the fixing part is connected to the lampshade. The brightness controller is installed above the lampshade and is connected to the lamp strip for controlling the brightness of the lamp strip. The light strip is installed inside the lampshade. The brightness controller obtains the ambient light brightness through sensors distributed around the classroom, and transmits the data to the controller through ZigBee so that the controller can adjust the brightness of the light strip. The utility model has a reasonable structure. The lampshade height can be flexibly adjusted by cooperating with the support rod and the lamp arm bracket. In addition, the light intensity can be adjusted by the sensor and the controller. The structure is simple and has good practicality.

[0004] After using the adjustable height classroom smart lamp, it was found that although the adjustable height classroom smart lamp can adjust the height, it is necessary to rotate the short threaded rod, remove the lamp cover, rotate the nut, remove the long threaded rod from the mounting hole, and then remove the lamp arm brackets on both sides and then install it. It is troublesome to adjust the height and is not very practical. Utility Model Content
