Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to a downlight. Background Technology
[0002] Existing downlights mainly include a heat sink, a light-emitting panel, a mounting base, a lens, a connecting base, a rotating base, and a reflector. The light-emitting panel is housed within and fixedly connected to the heat sink. The mounting base is fixedly connected to the heat sink. The connecting base is connected to the mounting base via a snap-fit mechanism at its bottom. The rotating base is rotatably connected to the connecting base. The reflector is snapped into the rotating base. The lens is positioned between the reflector and the connecting base.
[0003] One type of downlight has an L-shaped connecting slot on one side of the mounting base or connector, and a connecting block on the other side. The connecting block and the connecting slot engage to secure the mounting component and connector. However, this design carries the risk of the mounting component and connector coming loose. Therefore, some downlights use a J-shaped connecting slot on the mounting base. After the connecting block is inserted into the connecting slot, gravity holds it at the end of the slot, making it difficult for the mounting component and connector to come loose. However, this design is still not convenient for disassembly and assembly and the risk of loosening remains.
[0004] Therefore, a downlight with a simpler structure, more robust connection, and lower risk of use is needed. Utility Model Content

The rotation angle of the rotating seat can be positioned by the cooperation of the rotating seat positioning grooves and the third positioning protrusion.
