Description

Technical Field

[0001] The utility model relates to the field of LED lamps, and in particular to a novel rotatable and foldable LED lamp that can be used for smart home lighting, and an improved base assembly. Background Art

[0002] With the development of semiconductor lighting in recent years, LED lamps have been widely used in outdoor lighting and neon lights, home appliances, vehicles, computers, lighting and other products. Especially in lighting, LED lamps have gradually replaced incandescent lamps and fluorescent lamps, and have been widely used in many fields, including home lighting and auxiliary lighting.

[0003] CN 207262262 U discloses a reading lamp with adjustable illumination angle. It includes a support shaft arm, a lighting lamp body connected to the top end of the support shaft arm via a first hinge shaft, and a fixed seat mounted on the bottom end side of the support shaft arm via a steering shaft seat; the steering shaft seat includes a positioning column, a positioning sleeve, a positioning screw, a limit block, and a positioning ball head. The top end of the positioning sleeve is provided with a U-shaped limit notch, and the positioning sleeve is provided with a positioning ball seat. The positioning ball head is aligned and engaged in the positioning ball seat, and a force storage compression spring is clamped between the positioning ball seat and the positioning column. The utility model can be installed on a load-bearing object such as a desk, a class desk, or a bedside through the fixed seat. The structural effect of the first hinge shaft and the steering shaft seat enables students to adjust the height and illumination angle of the lighting lamp body according to their needs. Since only the fixed seat of the entire reading lamp occupies the physical position of the load-bearing object, it can effectively ensure the cleanliness of the desktop, making it convenient for students to carry out learning activities. Although the lamp disclosed in CN 207262262U mentions adjusting the height of the lamp body in one dimension via a hinge, its structure is relatively bulky and unsophisticated. Furthermore, the lamp body cannot pivot about its own rotation axis to change the angle of light in another dimension. Furthermore, its installation method and base structure are complex and not sufficiently stable.

[0004] CN 213810507 U discloses a horizontal adjustment structure for a reading light, including a bracket adjustment plate. This plate is fixedly connected to the light bar bracket at the rear end of the strip light body, thereby adjusting the horizontal angle of the strip light body. This allows the strip light body to be adjusted to a balanced state via the bracket adjustment plate, avoiding tilt caused by the strip light body being away from the support end of the light bar bracket, thereby ensuring the lighting effect and aesthetics of the reading light. The horizontal angle adjustment method and related structure of CN 213810507 U lack the advantages of manual engineering systems, and their adjustment range is also very limited.

[0005] The information included in this background art section of the specification of the present utility model, including any references cited herein and any description or discussion thereof, is included only for the purpose of technical reference and is not considered to be the subject matter that limits the scope of the present utility model.

From these descriptions, drawings, and claims, other features, purposes, and advantages of the present invention can be clearly understood.

[0041] It should be understood that the illustrated and described embodiments are not limited in application to the details of the construction and arrangement of the components set forth in the following description or illustrated in the drawings. The illustrated embodiments can be other embodiments and can be implemented or executed in various ways. The examples are provided by way of explanation rather than limitation of the disclosed embodiments. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the present invention without departing from the scope or essence of the disclosure of the present invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to still produce additional embodiments. Therefore, the disclosure of the present invention covers such modifications and variations that fall within the scope of the appended claims and their equivalent elements.

[0042] Similarly, it can be understood that the phrases and terms used herein are for descriptive purposes and should not be considered restrictive. The use of "including", "comprising", or "having" and their variants herein is intended to open - endedly include the items listed thereafter, their equivalents, and additional items.

[0043] The present invention will be described in more detail below with reference to the embodiments of the present invention.

[0044] Figure 1 is a schematic perspective view of the overall LED lamp that can be used as a reading lamp / auxiliary lighting according to an embodiment of the present invention. As Figure 1As shown, an LED lamp that can be used as a reading lamp according to an embodiment of the present utility model is generally shown. The LED lamp includes a lamp head 100 equipped with an LED illumination light source, which has, for example, a simple, compact, straight bar-shaped appearance as a whole, and a straight rod-shaped lamp post 200 for supporting the lamp head 100 and keeping it at a certain distance (generally height) from the installation position. The lamp head 100 and one end of the lamp post 200 are connected by a folding and rotating assembly 300. At the other end of the lamp post 200, there is a base assembly 400 for installation / connection to a desired position, such as a table, a sofa, a wall, or other expected installation positions, etc.

[0045] The lamp head 100 and the lamp post 200 are rotatably connected by the folding and rotating assembly 300, whereby the lamp head 100 and the lamp post 200 can rotate relative to each other. For example, the included angle A between the lamp head 100 and the lamp post 200 can range from 0 to 180 degrees. When the included angle A between the lamp head 100 and the lamp post 200 is approximately 0 degrees, the lamp head 100 and the lamp post 200 are actually "folded" together, which makes the LED lamp in a very compact and space-saving configuration / state at this time, facilitating transportation, storage, etc. When the included angle A between the lamp head 100 and the lamp post 200 is about 90 degrees, with the lamp post 200 in an upright state, the lamp head 100 is generally horizontal at this time, and can provide, for example, good downward illumination, such as desk reading illumination, for the user. This angle A can be conveniently adjusted according to the needs of the user, for example. When the included angle A between the lamp head 100 and the lamp post 200 is about 180 degrees, with the lamp post 200 in an upright state, the lamp head 100 is also generally straight and upright at this time, so as to achieve illumination for other functions besides reading, such as providing non-glare background light, rendering illumination, etc.

[0046] Figure 2A is Figure 1 A schematic exploded view of the LED lamp of the shown embodiment, showing the detailed structure and installation of the LED lamp that can be used as auxiliary lighting / reading lamp. Figure 2B is Figure 2A A schematic enlarged view of the connection part between the lamp head 100 and the lamp post of the shown LED lamp. Figure 2C is Figure 2A A schematic enlarged view of the connection part between the base assembly 400 and the other end of the lamp post of the shown LED lamp.

[0047] Figure 3A is Figure 1 A schematic longitudinal sectional view of the LED lamp of the shown embodiment, showing the internal and installation structure of the LED lamp. Figure 3B is Figure 3A A schematic enlarged view of the connection part between the lamp head 100 and the lamp post of the shown LED lamp. Figure 3C isFigure 3A The diagram is a schematic enlarged view of the base assembly 400 of the LED lamp and the connecting portion of the lamp pole at the other end.

[0048] The following combination Figures 1 - 3C This embodiment is described in further detail.

[0049] The lamp head 100 and the lamp pole 200 of the LED lamp can be rotated relative to each other by means of the folding rotating assembly 300 to a folded state ( Figure 1 The angle A shown is 0 degrees) and the straight line state ( Figure 1 The angle A shown is 180 degrees) to form any configuration within the range of 0-180 degrees.

[0050] The lamp holder 100 includes a tubular lamp holder shell 5 made of metal such as aluminum, and a front plastic end cap 1 is provided at one end of the lamp holder shell 5. The lamp holder shell 5 is preferably made of metal such as an aluminum tube because it can serve as a heat sink. Of course, the material is not limited to the present invention, and other materials can also be used, including other types of heat dissipation materials, etc.

[0051] The lamp housing 5 includes an LED light source and light panel assembly 6, a touch switch 3, a switch cap 2, and a diffuser 4 for evenly distributing light from the LED light source. The LED lamp can be turned on and off by the user simply touching the touch switch 3 located at the lamp base 100, greatly improving user convenience.

[0052] One end of the lamp housing 5 is pivotally connected to the upper folding rotating rod 11 via the coaxially arranged lamp pivot shaft 7, thereby forming an overall straight strip-shaped configuration of the lamp head 100. Figures 1 - 2A As shown, the left end of the lamp holder pivot shaft 7 (e.g., cave-shaped cross section) is fixedly inserted into one end of the tube cavity (e.g., cave-shaped cross section) of the lamp holder housing 5 in a shape-adaptive manner, and the right end of the lamp holder pivot shaft 7 (e.g., circular cross section) can be pivotally inserted into the left end of the upper folding rotating rod 11 of the circular tube cavity. Figures 2A - 2B and Figures 3A - 3BOn the premise of facilitating pivoting as shown, the lamp head 100 (including the lamp head housing 5 and the lamp head pivot shaft 7 together) can pivot left and right relative to the upper folding rotating rod 11 within a range of plus or minus 30 degrees (i.e., pivot around the central longitudinal axis of the lamp head 100). In other words, the lamp head 100 can pivot clockwise and counterclockwise relative to the upper folding rotating rod 11 by a maximum lighting angle of 30 degrees each. This lighting angle can be conveniently adjusted by the user by manually screwing the lamp head 100, thus greatly improving the operational convenience and user-friendliness. For example, a rear plastic end cap 12 can be installed at the right end of the upper folding rotating rod 11. The left limit block 9 and the right limit block 10 can also limit the pivoting angle, for example, limiting the left and right pivoting within a range of plus or minus 30 degrees.

[0053] As Figures 2A - 3B shown, the generally horizontally extending upper folding rotating rod 11 equipped with the rotating disk rotor 11A and the lower folding rotating rod 15 equipped with the corresponding rotating disk rotor 15A can be rotatably mounted relative to each other by means of a mounting pin 17 passing through the centers of both the rotating disk rotor 11A and the rotating disk rotor 15A, which simultaneously serves as a rotating pivot. A damping rubber ring 13 is provided between the rotating disk rotor 11A and the corresponding rotating disk rotor 15A mounted together by the central pin 17 to provide sufficient damping force for the relative rotation between the two, and to ensure that the included angle A between the upper folding rotating rod 11 and the lower folding rotating rod 15 can be maintained unchanged by virtue of this damping force after rotation, unless rotated again. With this structure, the upper folding rotating rod 11 and the lower folding rotating rod 15, and thus between the lamp head 100 and the lamp post 200, can be relatively folded and rotated within an included angle A range of 0 to 180 degrees. As shown in the figure, the central pin 17 can also be used to install a decorative cover 18 outside the rotating disk rotor 15A.

[0054] The lamp post 200 can include, for example, a support straight pipe 23 in the form of a metal pipe such as an aluminum pipe. As shown in the figure, for example, similar to the lamp head pivot shaft 7, the lower end of the lamp post pivot shaft 21 is inserted and fixed in the upper end of the support straight pipe 23 in a shape-fitting manner, and the upper end of the lamp post pivot shaft 21 (shown as a circular cross-section) is rotatably inserted into the lower end of the lower folding rotating rod 15 with a similarly circular lumen. Thus, with the left and right two rotating limit blocks 19 and 20 provided for limiting (for example Figures 2A - 2B and Figures 3A - 3BOn the premise of being convenient for horizontal rotation as shown, the upper section of the lamp post 200 including the lower folding and rotating rod 15 can horizontally rotate (i.e., pivot around the central longitudinal axis of the lamp post 200) within an angular range of, for example, 300 degrees relative to the lower section of the lamp post 200 (including the lamp post pivot shaft 21 and the support straight pipe 23). In other words, the lamp post 200 (including the lamp head 100 installed together with it) can be horizontally rotated and adjusted within an angular range of, for example, 300 degrees around its own central longitudinal axis. This adjustment angle can be conveniently completed by the user by manually screwing the lamp post 200, thus greatly improving the operation convenience and user-friendliness. These two rotation limit blocks 19 and 20 can also limit the horizontal rotation angle, for example, limiting the horizontal rotation angle within a range of 300 degrees.

[0055] As shown in the figure, the machine screws 8, 14, 16, and 22 can be respectively used to install and fix the corresponding components of the lamp head 100 and the lamp post 200. These components and installation methods are all common conventional means in the industry and will not be elaborated one by one.

[0056] The base assembly 400 installed at the bottom end of the lamp post 200 will be further described below with reference to the accompanying drawings.

[0057] In this embodiment, the lamp post 200 and the base assembly 400 adopt a completely separable design.

[0058] At the lower end of the support straight pipe 23 (which can have internal threads), a connection plug 24 made of, for example, metal can be installed by screwing (the connection end of which can have external threads and be screwed and connected to the internal threads at the lower end of the support straight pipe 23 for fixation). A plug-in male connector 25 with a conductive metal structure, such as a Figure 3C shown contact pin / public electrical contact, is installed inside the connection plug 24. The upper end of the plug-in male connector 25 (i.e., the wire-end shown in the figure) is connected to the circuit of the LED lamp to supply power for control and the light source, and its insertion end (lower end) with the contact pin / public electrical contact is configured to be inserted and connected to the plug-in female connector 29 to form an electrical connection, as described in detail below. As described above and as shown in the figure, the connection plug 24 can have external threads at its upper end with a smaller diameter and be screwed and connected to the internal threads at the lower end of the support straight pipe 23 to be fixed inside the support straight pipe 23 of the lamp post 200.

[0059] The base assembly 400 includes a cylindrical mounting member 34 made of, for example, metal with external threads. A mounting stop seat 32 in the form shown, for example, is fixedly installed on or integrally formed with the cylindrical mounting member 34. Figure 2C On the one hand, the mounting stop seat 32 can have a structure in the form of a flange, for example, and it can cooperate with a fixing fixture 33 in the form of a nut to clamp and install the base assembly 400 on, for example, a flat surface such as a tabletop, as further described below.

[0060] According to another example, the mounting stop 32 can be in the form of a separate sleeve with internal threads, which preferably also has a flange / flange-like structure and is configured to be screwed onto the cylindrical mounting member 34 and move up and down. In this way, during installation, the mounting stop 32 can also be screwed onto the cylindrical mounting member 34 to fix the LED lamp and its mounting base together with the fixing clamp 33 in the desired position. In this case, the fixing clamp 33 can be in the form of a nut or other suitable form, such as a flange / flange directly fixed / integrally formed on the cylindrical mounting member 34.

[0061] In the above-mentioned another example, an alternative mounting and construction method is that the connection plug 24 can also be additionally provided with an external thread that cooperates with the mounting stop 32 (for example, in the middle and lower sections as shown in the figure) so that it can be screwed and connected to the mounting stop 32. In this case, the mounting stop 32 can not only cooperate with the fixing clamp 33 to adjustably mount / clamp the base assembly 400 in the desired position, but also be screwed and fixed together with the connection plug 24. Although this mounting method is more firm and reliable, its flexibility and operational convenience will be affected.

[0062] A pluggable female connector 29 is installed in the lumen of the cylindrical mounting member 34. It is configured such that one end (for example, the lower end with wires as shown in the figure) is electrically connected to an external power source, such as an external USB power source, and the other end, that is, its electrically connecting end with a connection recess or hole (the upper end shown in the figure), is inserted and connected to the pluggable male connector 25 to form an electrical connection, thereby providing external power to the LED lamp via the pluggable male connector 25. An inner sleeve 30, such as made of plastic, can also be installed in the lumen of the cylindrical mounting member 34. It cooperates with the lumen to house a compression spring 31 in the lumen, so that when the connection plug 24 (together with the pluggable male connector 25 therein) is inserted into the lumen of the cylindrical mounting member 34, it facilitates the convenient and reliable insertion and docking with the pluggable female connector 29, as well as the removal and disconnection (separation from the docking).

[0063] The cylindrical mounting member 34 can be installed at the desired installation position, for example, by screwing it onto the corresponding threads at the installation position. The base assembly 400 can also be additionally provided with a fixing clamp 33 that cooperates with the cylindrical mounting member 34. In this way, the base assembly 400 can be conveniently clamped and fixed on both sides of a plane such as a desktop through the flange of the cylindrical mounting member 34 and the fixing clamp 33. An example of the fixing clamp 33 can be in the form of a nut, so that it can be screwed onto the external threads of the cylindrical mounting member 34 and thus tightened and clamped from the other side to achieve fixation.

[0064] Of course, those skilled in the art will appreciate that the cylindrical mounting member 34 and the fixing fixture 33 may also be provided in other forms, which also fall within the scope of the present application. For example, the cylindrical mounting member 34 may not have external threads, and the fixing fixture 33 may be fixed to or integral with the cylindrical mounting member 34. In this manner, the base assembly 400 can still be installed and fixed by the threaded mounting stop 32. However, this has the disadvantage of reducing the installation flexibility of the cylindrical mounting member 34, and substantially reducing its ability to adjust to tabletops or other mounting locations of varying thicknesses.

[0065] Other accessories, such as rubber rings 26 and 27 and metal clamping rings 28, washers, etc., are all for convenient and reliable installation and removal. These components and installation methods are conventional means commonly used in the industry and will not be described in detail.

[0066] The following briefly describes the completely detachable installation connection and disassembly between the base assembly 400 and the lamp pole 200. According to one example, the end of the lamp pole 200 equipped with the connecting plug 24 (e.g., aligned with the guide groove, if any) is pressed and inserted into the cylindrical mounting member 34 of the base assembly 400, and the nut-shaped fixing fixture 33 is rotated (e.g., clockwise) to complete the connection. At this time, the electrical connection male end of the plug-in male connector 25, i.e., the lower end shown in the figure, is inserted and securely engaged with the connection recess or recessed hole of the plug-in female connector 29 in the cylindrical mounting member 34, forming a tight interference fit or transition fit electrical connection. The compression spring 31 built into the tubular cavity of the cylindrical mounting member 34 facilitates this reliable electrical connection. When it is necessary to separate the base assembly 400 from the lamp pole 200, press and rotate the nut-shaped fixing fixture 33 (e.g., counterclockwise) until it is in place, and then pull it out to complete the separation of the lamp pole 200 from the base assembly 400.

[0067] Although the above embodiments, in conjunction with the accompanying drawings, describe the concepts of the present invention, those skilled in the art will appreciate that the electrical connection structures of the pluggable male connector 25 and the pluggable female connector 29 are interchangeable. That is, connector 25 may be a pluggable female connector having a connection recess or hole, and connector 29 may be a mating pluggable male connector having contact pins or male electrical contacts, with the two forming a tight interference fit or transition fit electrical connection when electrically connected. All of these are within the scope of the present invention.

[0068] In the case where the mounting stopper 32 is a separate component with threads, the base assembly 400 can also be tightened or loosened by screwing the mounting stopper 32 to assist in completing installation and removal, etc.

[0069] The LED lamps of the present utility model can be widely applied to the fields of industrial or household LED lighting. For example, they can be used for reading lighting, home lighting, office lighting, home atmosphere lights, sofa lighting, and various adjustable background / atmosphere lighting, etc. The foregoing description of several embodiments of the present utility model is presented for purposes of illustration. The foregoing description is not intended to be exhaustive nor to limit the present utility model to the precise steps and / or forms disclosed. Obviously, many modifications and variations can be made in light of the above teachings. The scope of the present utility model and all equivalents are intended to be defined by the appended claims.
