[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] The embodiment of the present application discloses an engineering lighting dimming device.

[0026] Reference Figure 1 , Figure 2 The engineering lighting dimming device includes a lamp holder 1 with a generally cylindrical shape. The lamp holder 1 is provided with a plurality of accommodating cavities 10 evenly spaced in the circumferential direction. The number of accommodating cavities 10 can be increased or decreased according to actual needs. In this embodiment, four accommodating cavities 10 are used as an example. Each adjacent accommodating cavity 10 is independent of each other. Four mounting seats 3 respectively arranged in the corresponding accommodating cavities 10 are detachably mounted on the lamp holder 1 through the accommodating cavity 10. A plurality of LED light sources 2 for providing lighting are mounted on the top of each mounting seat 3. Specifically, each mounting seat 3 is screwed and fixed to the lamp holder 1 by bolt fasteners.

[0027] like Figure 3 , Figure 4 As shown, a main lamp holder 4 is detachably mounted on the central axis of the lamp holder 1, and the main lamp holder 4 is inserted into the lamp holder 1 along the length direction of the central axis of the lamp holder 1. A plurality of LED lamp beads 40 for providing lighting are fixedly mounted on the top of the main lamp holder 4, and four mounting seats 3 are circumferentially arranged around the main lamp holder 4.

[0028] like Figure 3 , Figure 4 As shown, four first slots 11 are provided on the inner side wall of the lamp holder 1 facing the main lamp frame 4. The first slots 11 are evenly spaced around the main lamp frame 4 in the circumferential direction, and the first slots 11 correspond to the mounting base 3 one by one. The length direction of the first slot 11 extends along the direction in which the main lamp frame 4 is inserted into the central axis of the lamp holder 1. A second slot 30 located outside the lamp holder 1 is integrally formed on the side wall of the mounting base 3 facing the main lamp frame 4, and the second slot 30 is interconnected with the first slot 11 located below on the same side. Four plug-in strips 41 are integrally formed on the outer side wall of the main lamp frame 4 facing the first slot 11 and the second slot 30. The plug-in strips 41 are sequentially inserted into the first slot 11 and the second slot 30 opposite to each other along the direction in which the main lamp frame 4 is inserted into the lamp holder 1. Under the action of the plug-in strip 41, the rotation of the main lamp holder 4 in the lamp holder 1 can be limited, so that the main lamp holder 4 can be more stably fixed in the lamp holder 1. In addition, through the mutual plug-in cooperation between the plug-in strip 41 and the second slot 30, the stability of the mounting base 3 on the lamp holder 1 can be further improved, thereby limiting the rotation of the mounting base 3 on the lamp holder 1.

[0029] like Figure 3 , Figure 4 As shown, the lamp holder 1 is provided with four latch members 5 corresponding to the mounting base 3 in a one-to-one manner, and the latch members 5 are circumferentially arranged around the main lamp holder 4, and the latch members 5 are slidably arranged on the lamp holder 1 in a direction perpendicular to the direction in which the main lamp holder 4 is inserted into the lamp holder 1. The outer wall of the main lamp holder 4 is provided with insertion holes 42 corresponding to the latch members 5 in a one-to-one manner, and the insertion holes 42 are used for the ends of the latch members 5 opposite to each other to be inserted into the main lamp holder 4. By plugging and matching the ends of the latch members 5 with the insertion holes 42, the main lamp holder 4 can be locked in the lamp holder 1.

[0030] like Figure 3 , Figure 4 As shown, the outside of the latch member 5 is coaxially sleeved with a pressure spring 6 located in the lamp holder 1, and the pressure spring 6 expands and contracts along the sliding direction of the latch member 5 in the lamp holder 1. One end of the pressure spring 6 contacts the latch member 5, and the other end of the pressure spring 6 contacts the inner wall of the lamp holder 1. In a natural state, the pressure spring 6 is used to push the ends of the latch member 5 to be inserted and pressed into the respective opposite insertion holes 42.

[0031] like Figure 3 , Figure 4As shown, the latch member 5 is rotatably set on the lamp holder 1, and a limit plate 50 located outside the lamp holder 1 is fixedly set at one end of the latch member 5 away from the main lamp frame 4, and a support block 12 is set on the outer wall of the lamp holder 1 facing the limit plate 50, and the support block 12 is located on the sliding path of the limit plate 50.

[0032] like Figure 4 , Figure 5 As shown, the bottom of the lamp holder 1 is detachably mounted with a base 7, and the outer circumferential surface of the base 7 is provided with mounting ears 70 at intervals, and the mounting ears 70 are used for inserting bolt fasteners to achieve the fixing of the lamp holder 1 on the building. The central axis of the base 7 is also penetrated with a threading hole 71 for inserting external wires into the lamp holder 1, and the wires inserted from the threading hole 71 are used to be electrically connected to the corresponding LED light source 2 and LED lamp bead 40.

[0033] The implementation principle is: when installing the main lamp holder 4, it is only necessary to insert the connecting strip 41 into the respective opposite second slots 30 and first slots 11 in turn. When the socket 42 on the main lamp holder 4 moves to be opposite to the end of the latch member 5, the pressure spring 6 which is originally in a compressed state will push the latch member 5 to move toward the socket 42. Finally, the end of the latch member 5 will be inserted and pressed into the socket 42. Through the mutual plug-in cooperation between the latch member 5 and the socket 42, the main lamp holder 4 can be fixed in the lamp holder 1. The whole locking process is quick and convenient in one step. When it is necessary to release the locking of the main light stand 4 by the latch 5, it is only necessary to pull the latch 5 in the direction away from the main light stand 4. After the ends of the latch 5 are withdrawn from their respective sockets 42, the limit plate 50 is set on the support block 12 by rotating the latch 5. At this time, under the limit of the support block 12, it can be ensured that the ends of the latch 5 remain withdrawn from the socket 42, which facilitates subsequent maintenance personnel to remove the main light stand 4 from the lamp holder 1. In summary, the present application will not be affected by some faulty LED light sources 2, causing other LED light sources 2 to be unable to continue working, thereby ensuring that lighting can continue to be provided during maintenance, meeting the needs of nighttime lighting, and having a humanized design.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
