[0030] The present invention provides a multifunctional combined commercial lighting lamp as Figures 1-8 shown, including a lamp body 1, a light source board 2 is fixedly arranged inside the lamp body 1, a light source board fixing bracket 3 is fixedly arranged on the top of the light source board 2, a lens 4 is fixedly arranged on the top of the light source board fixing bracket 3, a reflector 5 is fixedly arranged on the top of the lens 4, a diffuser plate 6 is fixedly arranged on the surface of the reflector 5, a connection chute 7 is opened at the bottom of the lamp body 1, power supply box connection members 8 are fixedly arranged at both ends of the lamp body 1, and power supply mechanisms are arranged outside both of the power supply box connection members 8;
[0031] The power supply mechanism includes an upper cover 9 of the power supply box and a lower cover 10 of the power supply box. The upper cover 9 of the power supply box and the lower cover 10 of the power supply box are fixedly installed correspondingly. A U-shaped card slot 11 is fixedly opened on one side of the upper cover 9 of the power supply box, a connection card block 12 is fixedly arranged on one side of the lower cover 10 of the power supply box, the U-shaped card slot 11 and the connection card block 12 are correspondingly clamped, a fixed shaft 13 is fixedly arranged on the surface of the power supply box connection member 8, the fixed shaft 13 penetrates through the U-shaped card slot 11, and a square limit block 14 is fixedly arranged at the end of the fixed shaft 13;
[0032] Inside the lower cover 10 of the power supply box, a two-wire power connection post 15 is movably arranged. On the outer end surface of the two-wire power connection post 15, a fixed clamping block 16 is fixedly arranged. The shape of the fixed clamping block 16 is set as a rounded rectangle. At the inner end of the two-wire power connection post 15, an operating rod 17 is fixedly arranged, and the operating rod 17 extends out of the outside of the lower cover 10 of the power supply box.
[0033] Furthermore, a plurality of LED lamp beads are sequentially and evenly arranged on the surface of the light source board 2. The numbers of the lens 4 and the reflector 5 are correspondingly set according to the number of the LED lamp beads, which is convenient for freely adjusting the LED lamp beads on the light source board 2 to achieve different lighting effects.
[0034] Furthermore, a connection clamping part 18 is fixedly arranged at the bottom of the power supply box connecting part 8. Both ends of the connection sliding groove 7 are communicated with the outside of the lamp body 1. The connection clamping part 18 is fixedly inserted into the connection sliding groove 7.

When the lamp body 1 is adjusted to rotate, the fixed shaft 11 rotates in the formed circular hole. Since the circular hole is formed by the combination of the U-shaped clamping groove 11 and the U-shaped groove 19, the opposite U-shaped clamping groove 11 and U-shaped groove 19 will exert a clamping force on the fixed shaft 13, thereby increasing the friction of the fixed shaft 13, that is, it is convenient to clamp and fix the fixed shaft 13 after adjusting the angle to maintain the lighting angle.
[0036] Furthermore, a three-wire power connection post 20 is arranged on one side of the two-wire power connection post 15. A fixed clamping block 16 is also fixedly arranged on the outer end surface of the three-wire power connection post 20. Gears 21 are fixedly arranged at the inner ends of both the two-wire power connection post 15 and the three-wire power connection post 20. The two gears 21 are meshed with each other. In daily life, the power cord connection has two-wire connection and three-wire connection. The three-wire power connection post 20 is to adapt to the three-wire connection method. The transmission connection between the two-wire power connection post 15 and the three-wire power connection post 20 is carried out by using the gear 21, which is convenient for the rotation of the three-wire power connection post 20. Similarly, the fixed clamping block 16 is used to connect with the installation hole on the ceiling, which is convenient for the installation of this commercial lighting lamp.
[0037] The specific implementation method is as follows: when installing the commercial lighting, first, a mounting hole is opened on the ceiling, and the mounting hole should correspond to the shape of the fixed card block 16, so that the fixed card block 16 can pass through it conveniently. The two-wire power connection column 15 on the lower cover 10 of the power box is inserted into the mounting hole, and the power line is fixedly connected to the two-wire power connection column 15 at the same time, so that the wiring is convenient. Then, the operating lever 17 is toggled to drive the fixed card block 16 on the two-wire power connection column 15 to rotate, so that the fixed card block 16 is misaligned with the preset mounting hole, so as to prevent the fixed card block 16 from detaching from the mounting hole, so that the lower cover 10 of the power box is fixed on the ceiling, and the power box connector 8 is fixedly installed at both ends of the lamp body. The fixed card block 16 on the power box connector 8 The shaft 13 passes through the U-shaped slot 11 on the upper cover 9 of the power box, and then the upper cover 9 of the power box is fixedly installed corresponding to the lower cover 10 of the power box, that is, the lower cover 10 of the power box installs the upper cover 9 of the power box by screw combination, and the connecting block 12 on the lower cover 10 of the power box is inserted into the U-shaped slot 11 to close the U-shaped slot 11. At the same time, the square limit block 14 on the fixed shaft 13 prevents the fixed shaft 13 from being separated from the U-shaped slot 11, so as to realize the movable connection between the lamp body 1 and the upper cover 9 of the power box. The U-shaped groove at the top of the connecting block 12 and the U-shaped slot 11 are just combined into a circular hole for the movable fixed shaft 13. The lamp body 1 is directly rotated to adjust the lighting angle of the lamp body 1, so as to realize the installation of the commercial lighting lamp.
[0038] like Figures 9-10 A multifunctional combined commercial lighting is shown, wherein both ends of the lamp body 1 also include embedded mounting fixtures 22 and hanging mounting plugs 23 fixedly arranged thereon, and the connection method between the embedded mounting fixtures 22 and hanging mounting plugs 23 and the lamp body 1 is the same as the connection method between the lamp body 1 and the power box connector 8.
[0039] Furthermore, a fixed installation spring frame 24 is fixedly arranged on the surface of the embedded installation fixture 22, and a torsion spring is arranged at the connection between the fixed installation spring frame 24 and the embedded installation fixture 22. When the embedded installation is performed, the fixed installation spring frame 24 will flip upward, so that it can be conveniently extended into the installation hole on the ceiling together with the lamp body 1, and then the elastic force of the torsion spring will be used to make the fixed installation spring frame 24 flip downward and return, so that the fixed installation spring frame 24 can be pressed against the ceiling and an upward force is applied to the lamp body 1. This installation method is very common in spotlight installation.
[0040] Furthermore, a hanging bracket 25 is arranged between the two hanging installation plugs 23, and the hanging bracket 25 is movably connected to the connecting slide groove 7. The number of the hanging brackets 25 is set to two, which are symmetrically arranged about the center line of the lamp body 1. A hanging line 26 is fixedly connected to the top of the two hanging brackets 25, and the two hanging lines 26 are set to have the same length. The two hanging lines 26 have the same length, which is convenient for the lamp body 1 to be horizontally suspended on the ceiling.
[0041] The specific implementation method is as follows: when the lamp body 1 is suspended and installed, the two suspension brackets 25 are first placed in the connecting slide grooves 7 on the lamp body 1, and then the two suspension installation plugs 23 are fixedly installed on the two ends of the lamp body 1, and the two ends of the connecting slide grooves 7 are closed to prevent the suspension brackets 25 in the connecting slide grooves 7 from sliding out. The suspension wires 26 are fixedly connected to the suspension brackets 25, and the suspension wires 26 are fixed on the ceiling. The two suspension wires 26 have the same length, which is convenient for the lamp body 1 to be horizontally suspended on the ceiling. When the lamp body 1 is embedded in the ceiling, it is also necessary to open a mounting hole in the ceiling. The mounting hole corresponds to the size of the lamp body 1. The entire lamp body 1 is embedded and installed in the ceiling, and the fixed installation spring frame 24 is used to resist the ceiling. Since one end of the fixed installation spring frame 24 connected to the lamp body 1 is set as a torsion spring, the elastic force of the torsion spring is used to realize the rotation of the fixed installation spring frame 24, and an upward force is applied to the lamp body 1 to realize the embedded installation of the commercial lighting. The two installation methods are also applicable to the present invention, providing different installation options and further adapting to different installation situations.
