Detailed implementation

[0065] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0066] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0067] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0068] In the description of this application, it should be noted that, unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0069] This application provides a lighting fixture, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment has its own emphasis. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0070] Referring to Figure 1 and Figure 2 , the lighting fixture provided by this application includes a lamp head 1, a lamp post 2 connected to the lamp head 1, and a base 3 connected to the bottom end of the lamp post 2. A vertical through groove 20 is provided in the lamp post 2 for accommodating a lifting structure 21. More specifically, the above lamp post 2 is a square, hollow, long bar-shaped rod structure. Alternatively, the above lamp post 2 is a cylindrical, hollow rod structure.

[0071] Among them, the above lifting structure 21 is used to adjust the position of the lamp head 1 on the lamp post 2, that is, the height of the lamp head 1 can be adjusted through the lifting structure 21. The lifting structure 21 includes a mounting seat 211, a sliding member 212, and an elastic element 213. The mounting seat 211 has a mounting portion and a guiding portion. The mounting portion is connected to the lamp head 1, and the guiding portion is in vertical sliding fit with the mounting side plate 22 of the lamp post 2; the sliding member 212 is arranged in the vertical through groove 20 and is fixedly connected to the guiding portion; the elastic element 213 is installed in the vertical through groove 20 and has a fixed portion and a free portion located below the fixed portion. The fixed portion is connected to the top of the lamp post 2, and the free portion is connected to the sliding member 212. Among them, the fixed portion can provide an upward traction force to the free portion, so that the sliding member 212 and the mounting seat 211 are stationary to position the lamp head 1 on the lamp post 2.

[0072] During specific use, the user applies an upward or downward external force to the lamp head 1, enabling the lamp head 1 to move up and down along the lamp post 2. When the user's hand disengages from the lamp head 1, that is, the external force applied to the lamp head 1 disappears, and since the fixing part can provide an upward traction force to the free part, the sliding member 212 and the mounting seat 211 are stationary to position the lamp head 1 on the lamp post 2. That is, the magnitude of the above traction force is equal to the sum of the weights of the components fixed on the free part, and the directions of the two forces are opposite, so that the lamp head 1 and the elastic element 213 are kept in a balanced state. Thus, the user can adjust the height of the lamp head 1 with a very small external force, and since there is a vertical through groove 20 in the lamp post 2, that is, the lamp head 1 can be positioned at any position on the lamp post 2, that is, stepless adjustment of the height of the lamp head 1 is achieved, thereby enhancing the user experience.

[0073] Based on the above embodiment, the elastic element 213 is a constant force spring, the fixing part is the fixed end of the constant force spring, the free part is the winding end of the constant force spring, an arc-shaped accommodating groove 2121 for accommodating the winding end is formed at the bottom of the sliding member 212, and a first avoidance groove 2122 is formed on the side wall of the sliding member 212 for the fixed end to pass through the sliding member 212 from the first avoidance groove 2122, thereby facilitating the fixed connection of the fixed end of the constant force spring to the top of the lamp post 2, as Figure 3 、 Figure 4 and Figure 5 shown.

[0074] Alternatively, the elastic element 213 is a corrugated pipe, the fixing part is the first end of the corrugated pipe, the free part is the second end of the corrugated pipe. Thus, the up and down movement of the lamp head 1 is realized through the elongation and contraction of the corrugated pipe, and it is ensured that the force causing the corrugated pipe to deform can keep the sliding member 212 stationary in the vertical sliding groove 221.

[0075] Referring to Figure 2 and Figure 6 , the lifting structure 21 further includes an end cap 214 and a fixing plate 215. The end cap 214 is arranged at the top end of the vertical through groove 20; the fixing plate 215 is arranged between the end cap 214 and the sliding member 212 and is fixedly connected to the end cap 214. A second avoidance groove 2151 corresponding to the first avoidance groove 2122 is formed on the fixing plate 215. The fixed end is formed with a fixed folding edge 2131, and the fixed folding edge 2131 passes through the second avoidance groove 2151 to be connected to the fixing plate 215, making the fixation between the constant force spring and the fixing plate 215 relatively simple and convenient and easy to achieve.

[0076] Among them, the above-mentioned fixed hem 2131 is connected to the upper surface of the fixed plate 215. That is, a set of first threaded holes 2153 are formed on the fixed plate 215, and fixed threaded holes are provided on the fixed hem 2131. Thus, the connection between the two can be achieved through a set of fastening screws. Alternatively, a fixed post is made on the upper surface of the fixed plate 215, and a through hole is provided on the fixed hem 2131, so that the through hole penetrates through the above-mentioned fixed post.

[0077] More specifically, the size and structure of the end cap 214 match the size and structure of the vertical through groove 20 to block the top of the vertical through groove 20 and prevent dust and impurities from entering the lamp post 2. Exemplarily, a sealing member is provided at the connection between the end cap 214 and the lamp post 2 to better achieve the sealing performance between the two.

[0078] To realize the connection between the end cap 214 and the fixed plate 215, a hook 2141 is formed on one of the end cap 214 and the fixed plate 215, and a slot 2152 is formed on the other. The hook 2141 and the slot 2152 are snap-connected, so that the fixed connection between the two can be realized without the need for external tools.

[0079] Exemplarily, a hook 2141 is formed on the end cap 214 of the present application, as Figure 2 shown. A slot 2152 is formed on the side wall of the fixed plate 215, as Figure 6 shown. More specifically, the second avoidance groove 2151 is located on the left side wall of the fixed plate 215. There are two slots 2152, which are respectively arranged on the front side wall and the rear side wall of the fixed plate 215. Correspondingly, there are also two hooks 2141.

[0080] Alternatively, the end cap 214 and the fixed plate 215 can also adopt a threaded connection, a magnetic connection, or an adhesive connection. Or, an interference fit is provided between the end cap 214 and the vertical through groove 20, and the fixation between the two can also be realized in this way.

[0081] Referring to Figure 2 and Figure 5 , a plurality of connectors 216 protruding from the inner wall of the lamp post 2 are formed inside the lamp post 2. The fixed plate 215 is installed at the top of the connectors 216, and the sliding member 212 is slidably fitted between the plurality of connectors 216. That is, the connectors 216 not only realize the fixed connection between the fixed plate 215 and the lamp post 2, but also can position the sliding member 212 in the vertical sliding groove 221 through the connectors 216.

[0082] Exemplarily, the above-mentioned sliding member 212 is a slider, and the above-mentioned setting can also prevent the outer contour of the sliding member 212 from completely fitting with the inner wall of the lamp post 2, that is, a part of the area on the sliding member 212 is guided and positioned by the connecting member 216. In this way, there will be a gap between the sliding member 212 and the lamp post 2, which is convenient for adding lubricating oil into the lamp post 2.

[0083] Alternatively, the above-mentioned sliding member 212 is made of a solid lubricating material, for example, materials such as nylon, polytetrafluoroethylene, polyacetal, polyoxymethylene, polycarbonate, polyamide, polysulfone, etc.

[0084] Continue to refer to Figure 6 , in the horizontal projection, the connecting member 216 includes a first connecting arm 2161 and a second connecting arm 2162, and a connecting portion 2163 connecting the first connecting arm 2161 and the second connecting arm 2162. The first connecting arm 2161 and the second connecting arm 2162 are respectively connected to the side walls of the vertical through groove 20, and the fixing plate 215 is fixedly connected to the connecting portion 2163 to realize the fixation between the fixing plate 215 and the lamp post 2. In this way, compared with the technical solution of connecting the two by a threaded structure, the technical solution adopted in the present application does not need to open a horizontally arranged threaded through groove on the housing of the lamp post 2, and the lamp post 2 and the fixing plate 215 are fixedly connected by screws, ensuring that the sealing performance of the structure of the lamp post 2 is better.

[0085] More specifically, the horizontal projection shape of the above-mentioned lamp post 2 is a rectangle, and the horizontal projection behavior of the vertical through groove 20 is also a rectangle. The first connecting arm 2161 and the second connecting arm 2162 are perpendicular to each other. The first connecting arm 2161 and the second connecting arm 2162 are respectively connected to two adjacent side walls of the vertical through groove 20 and enclose a cavity. The connecting portion 2163 is arranged at the connection of the first connecting arm 2161 and the second connecting arm 2162 and recesses into the cavity, avoiding the connecting portion 2163 from affecting the sliding of the sliding member 212 and ensuring that the internal structure of the lamp post 2 is relatively compact.

[0086] In order to make the guiding effect of the connecting member 216 on the sliding member 212 stable and reliable, the extending lengths of the first connecting arm 2161, the second connecting arm 2162 and the connecting portion 2163 in the vertical direction in the above-mentioned connecting member 216 are greater than or equal to the moving distance of the sliding member 212.

[0087] Among them, the above-mentioned lamp post 2 is an injection molded part, and the connecting member 216 and the lamp post 2 are of an integral structure. Considering the manufacturing process of the above structure, a vertically arranged connecting hole 21631 is formed in the connecting portion 2163 of the present application, and a demolding groove 21632 is formed on the side wall of the connecting hole 21631. The opening of the demolding groove 21632 faces the inside of the lamp post 2.

[0088] More specifically, the above-mentioned connecting hole 21631 is a threaded hole, and a group of second threaded holes 2054 corresponding to the threaded hole are formed on the above-mentioned fixing plate 215, that is, the connecting member 216 and the fixing plate 215 are also fixedly connected by screws.

[0089] Alternatively, the above-mentioned connecting hole 21631 is a through hole, and a convex column is formed downward on the lower surface of the above-mentioned fixing plate 215. The convex column extends into the through hole and is in interference fit with the through hole.

[0090] Please continue to refer to Figure 2 、 Figure 4 and Figure 7 , the above-mentioned lighting fixture further includes a first connection structure 4, which is used to connect the lamp post 2 and the lamp head 1. The first connection structure 4 includes a first lamp head magnetic part 41 and a second lamp head magnetic part 42. The first lamp head magnetic part 41 is fixedly connected to the mounting seat 211; the second lamp head magnetic part 42 is fixedly connected to the lamp head 1. The first lamp head magnetic part 41 and the second lamp head magnetic part 42 are attracted to each other, thereby ensuring that the connection between the lamp post 2 and the lamp head 1 is simpler and more convenient, and facilitating the installation and disassembly between the two.

[0091] Exemplarily, in order to reduce the manufacturing cost of the above-mentioned first connection structure 4, the above-mentioned first lamp head magnetic part 41 is an iron sheet, and the second lamp head magnetic part 42 is a magnet. Of course, it is also possible to make the first lamp head magnetic part 41 a magnet and the second lamp head magnetic part 42 an iron sheet. It should be noted that the above-mentioned first lamp head magnetic part 41 can also be made of a metal material having iron, nickel, cobalt, etc.

[0092] Refer to Figure 7 , the mounting seat 211 is in a box shape, the opening of the mounting seat 211 faces the lamp head 1, the mounting portion 2111 is a mounting cavity formed in the mounting seat 211, the guiding portion 2112 is a guiding protrusion formed on the bottom wall of the mounting seat 211, the guiding protrusion extends in a direction away from the opening of the mounting seat 211, and a vertical sliding groove 221 (labeled part Figure 2 ) is formed on the mounting side plate 22. The guiding protrusion is slidably fitted in the vertical sliding groove 221, and the sliding fit between the two is realized through the vertical sliding groove 221 and the guiding protrusion.

[0093] More specifically, a connecting threaded hole 2123 is formed on the side wall of the above-mentioned slider 212 close to the mounting side plate 22. Correspondingly, another threaded connection hole corresponding to the connecting threaded hole 2123 is formed on the guiding portion 2112 of the above-mentioned mounting seat 211. The adjusting member 2115 (the label is shown in Figure 4 ) is threadedly connected to the aforementioned two threaded holes to fix the slider 212 and the mounting seat 211, as shown in Figure 9 .

[0094] Among them, the above-mentioned adjusting member 2115 is a fastening screw, as shown in Figure 4 . In this way, by adjusting the depth of the fastening screw screwed into the connecting threaded hole 2123 in the slider 212, the friction force between the slider 212 and the inner side wall of the lamp post 2 can be adjusted to ensure that the slider 212 slides up and down with the lamp head 1 more easily and can also ensure better stability of the above-mentioned slider 212 in a static state.

[0095] Therefore, in this application, a fastening screw realizes the function of adjusting the friction force between the slider 212 and the inner side wall of the lamp post 2 and also realizes the fixing function of the slider 212 and the mounting seat 211.

[0096] Referring to Figure 4 and Figure 8 , a first limiting portion 2113 is formed on the above-mentioned mounting seat 211, and a second limiting portion is formed on the above-mentioned mounting side plate 22. The first limiting portion 2113 and the second limiting portion cooperate to position the connection between the mounting seat 211 and the mounting side plate 22, ensure the installation position accuracy of the mounting seat 211, and also ensure the depth of insertion of the mounting seat 211 into the vertical sliding groove 221.

[0097] Exemplarily, the first limiting portion 2113 is the bottom wall of the mounting seat 211 (i.e., the left side wall of the mounting seat 211 in Figure 9 ), the second limiting portion is the outer wall surface of the mounting side plate 22, and the bottom wall abuts against the outer wall surface of the mounting side plate 22.

[0098] Alternatively, a limiting groove recessed toward the inside of the lamp post 2 can also be formed on the wall surface of the vertical sliding groove 221. Correspondingly, a limiting protrusion is formed on the bottom wall of the mounting seat 211, and the limiting protrusion is clamped in the limiting groove.

[0102] Based on the above embodiment, a mounting seat limiting portion is formed on the accommodating groove 11, and a lamp holder limiting portion is formed on the outer wall of the mounting seat 211. The lamp holder limiting portion and the mounting seat limiting portion cooperate with each other to limit the rotation of the mounting seat 211 in the accommodating groove 11, thereby ensuring that the two are fixed and the relative positions thereof will not change, so that the position of the lamp holder 1 is fixed.

[0103] For example, the accommodating groove 11 is a rectangular groove, and the limiting portion of the mounting seat is a corner of the accommodating groove 11. Correspondingly, the mounting seat 211 is in the shape of a square box, and the lamp holder limiting portion is a corner of the mounting seat 211. The corner of the mounting seat 211 is clamped at the corner of the accommodating groove 11, thereby eliminating the need to set up other components to fix the relative position relationship between the two, thereby ensuring that the connection between the lamp holder 1 and the mounting seat 211 is more stable and reliable.

[0104] Reference Figures 10 to 12 A plug-in slot 1011 is formed on the first cover body 101 , and the plug-in slot 1011 is located on the side of the accommodating slot 11 away from the lamp pole 2 .

Figure 15 ), the lamp cap spring pin and the base spring pin are connected by a wire 23, such as Figure 16 Specifically, the light source board 15 may be an optoelectronic integrated board. The optoelectronic integrated board includes a power board and an LED light source arranged on the power board, wherein the power board may be an FPC substrate.

[0113] More specifically, a waist-shaped through hole is formed on the above-mentioned first lamp holder magnetic suction component 41 and the second lamp holder magnetic suction component 42, so that the elastic connecting end of the lamp holder spring pin fixed on the first spring pin mounting plate 16 can pass through the waist-shaped through hole and be electrically connected to the first spring pin circuit board 24 arranged on the side of the first lamp holder magnetic suction component 41 away from the second lamp holder magnetic suction component 42, and the upper end of the wire 23 is electrically connected to the side of the first spring pin circuit board 24 away from the first lamp holder magnetic suction component 41.

[0114] It should be noted that in order to achieve electrical connection between the above-mentioned wire 23 and the first spring needle circuit board 24, a threading space 218 is formed between the other side wall of the above-mentioned sliding member 212 (the other wall adjacent to the wall on which the first avoidance groove 2122 is set on the sliding member 212) and the inner wall of the lamp pole 2. The wire 23 extends upward through the threading space 218 to the U-shaped threading groove 2124 and then bends to pass through the wire hole 2125. A threading hole corresponding to the wire hole 2125 is formed on the guide portion 2112 in the above-mentioned mounting seat 211, so that the upper end of the wire 23 can extend into the mounting seat 211 and be electrically connected to the first spring needle circuit board 24 of the mounting seat 211.

[0115] Subsequently, the lower end of the wire 23 is electrically connected to the upper end of the base spring pin 2171 fixed on the second spring pin mounting plate 217, the base spring pin passes through the waist-shaped hole on the second base magnetic suction member and is electrically connected to the base spring pin circuit board 37, and the base spring pin circuit board 37 is electrically connected to the drive control board 32. Thus, the electrical connection between the lamp head 1, the lamp pole 2 and the base 3 is realized, thereby realizing the lighting function of the lighting fixture.

[0116] Among them, the first spring pin mounting plate 16 and the lamp holder spring pins arranged on the first spring pin mounting plate 16 are of an integral structure, and the second spring pin mounting plate 217 and the base spring pins 2171 arranged on the second spring pin mounting plate 217 are of an integral structure. Thus, the modularization of the above components is realized, the number of components in the lighting fixture is reduced, and the assembly efficiency of the above lighting fixture is decreased.

[0117] In order to realize the intelligent dimming of the above lighting fixture, the above lighting fixture further includes a ranging module and a dimming module.
