Description

Technical Field

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

[0002] In open and busy areas like city squares, stadiums, recreational areas, and parking lots, large-scale, centralized lighting is often achieved through the use of installed lighting fixtures. Traditionally, these fixtures consist of a light pole and a lamp mounted on top of the pole. The fixture is fixed to the pole, providing a fixed illumination angle. Because the fixture is fixed to the pole, the angle cannot be adjusted to suit the specific needs of the location. Furthermore, the overall structure of the fixture is complex, requiring numerous assembly steps.

[0003] Chinese invention patent number CN117308045B describes a multi-angle adjustable lighting device for tunnel lighting. The technical solution describes "utilizing lateral adjustment of a drive screw to drive a toothed plate into engagement with a gear, thereby adjusting the circumferential angle of the electric telescopic rod. The electric telescopic rod is then used to drive the lateral traction ball, achieving angular rotation of the multi-section light panel, thereby ensuring that the light panel can be adjusted at different angles." While this device can adjust the lighting angle of the lighting fixture, it suffers from a complex adjustment structure and high cost.

[0004] Therefore, it is urgent to research and develop a lighting device that can adjust the angle while reducing structural complexity and solving the above technical problems. Summary of the Invention

[0009] A fixing clip is provided on the outer walls of both sides of the lamp holder, and a locking piece is provided on the fixing clip. The locking piece passes through the fixing clip and is locked with the lamp holder. When the locking piece is not locked with the lamp holder, the fixing clip and the lamp holder rotate relative to each other. When the locking piece is locked with the lamp holder, the fixing clip and the lamp holder are relatively fixed.

[0010] Compared with the prior art, the lighting device of the present invention simplifies the structural complexity of the lighting device by providing a lamp cover in the installation groove opened on the lamp holder to cover and shield the circuit board and LED lamp beads in the installation groove, and then using a locking piece to lock the lamp cover on the lamp holder. In addition, fixing clips are provided on the outer walls of both sides of the lamp holder to be fixed relative to the lamp holder by locking pieces. The relative angle between the fixing clip and the lamp holder is adjusted when the locking piece is unlocked, thereby realizing the adjustment of the illumination angle of the lighting device, which can reduce the structural complexity while adjusting the angle.

[0011] In some embodiments, a through hole is provided on the fixing clip, a locking screw hole is provided on the lamp holder, and the locking member is a locking screw, the end of which passes through the through hole and is screwed into the locking screw hole.

[0012] The fixing clamp and the lamp holder are connected and fixed by using a locking screw as a locking part in conjunction with the locking screw hole on the lamp holder, thereby improving the connection stability and the convenience of disassembly and assembly.

[0013] In some embodiments, at least two connecting screw holes are provided at the bottom of the mounting groove, a first through hole is opened at a position corresponding to the connecting screw hole on the circuit board, a second through hole is opened at a position corresponding to the connecting screw hole on the lamp cover, and connecting screws are also included that pass through the second through hole and the first through hole in sequence and are screwed to the connecting screw hole.

[0014] The lamp cover and the lamp holder are connected and fixed by adopting the screw connection method of connecting screws and connecting screw holes, thereby improving the connection stability and disassembly convenience between the lamp cover and the lamp holder.

[0015] In some embodiments, a connecting column matching the connecting screw hole is provided on the side of the lamp cover close to the circuit board, the second through hole is formed in the connecting column, and the connecting column passes through the first through hole and presses against the bottom inner wall of the mounting groove.

[0016] By adopting a structure in which the connecting column forms the second through hole and passes through the first through hole, the connection stability between the lamp cover and the lamp holder in the mounting groove is further improved.

[0017] In some embodiments, a plurality of third through holes are provided on the circuit board, a plurality of fixing screw holes matching the third through holes are provided on the bottom inner wall of the mounting groove, and a plurality of fixing screws passing through the third through holes and screwed into the fixing screw holes are provided on the circuit board.

[0018] The circuit board and the lamp holder are connected and fixed by adopting a screw connection method of fixing screws and fixing screw holes, thereby improving the connection stability and disassembly convenience between the circuit board and the lamp holder.

[0019] Based on the above technical solution, the present invention has the following beneficial effects compared with the prior art:
