Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and in particular to a lighting fixture. Background Technology

[0002] Lighting fixtures contain light source modules that emit light. Existing light source modules are typically fixed to the lamp body with screws, which offer advantages such as low cost and good stability. However, the disadvantages are also significant. The light source component is the most easily damaged part of a lighting fixture. Therefore, there is a large market demand for replaceable light source components. However, screw fixing requires tools for both installation and removal, making it inconvenient. Furthermore, screws on aluminum castings are prone to stripping, and iron screws are susceptible to corrosion. The machining of the threaded holes in the lamp body is also relatively complex, resulting in high production costs.

[0003] Furthermore, when used as streetlights, the fixtures sometimes require maintenance. When using screws for fixing, accidents involving screws or screwdrivers falling are common during work at heights, and disassembly and assembly are extremely inconvenient.

[0004] While some tool-free assembly / disassembly designs exist in the current technology, most require a number of fixing mechanisms consistent with screw fixation. Using too many parts also leads to cumbersome assembly / disassembly and increases the risk of accidental drops. Summary of the Invention

[0005] To address the aforementioned problems, or at least partially address the aforementioned technical problems, in one embodiment of this application, a lighting fixture is provided, comprising:

[0006] The lamp body is provided with at least two fixing posts;

[0007] A light source assembly, wherein a through hole is provided on the light source assembly, and the light source assembly is sleeved on the fixed post through the through hole;

[0008] An elastic fastener is provided with at least two abutting portions. Under the action of its own elastic restoring force, the elastic fastener tends to deform so that the two abutting portions abut against the two fixing posts, thereby fixing the light source assembly on the fixing posts.

[0009] In existing technologies, a flexible fastener is required to fix each part of the light source assembly, which increases the number of components. Moreover, the small size of the flexible fastener requires more delicate operation, making its assembly and disassembly more difficult.

[0010] The elastic fastener provided in this application embodiment can simultaneously support and fix two fixing posts, thus significantly reducing the number of elastic fasteners required compared to the prior art. Furthermore, since it needs to support at least two fixing posts respectively, the elastic fastener can be designed as a long strip shape that is easy to grip and operate. Accordingly, compared to the prior art, the elastic fastener provided in this application embodiment is not only less prone to falling during loading and unloading, but is also more convenient to operate.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0022] Implementation Method 1

[0023] This application provides a lighting fixture.

[0024] The inventors of this application have discovered that, in the prior art, the tool-free disassembly and assembly design is still very complex and cumbersome.

[0025] For example, in Chinese utility model patent CN206207032U, entitled "Tool-Free Quick-Installation LED Module and Lighting Fixture," a screw-like positioning rod with a pull ring and elastic element is used. This positioning rod is essentially not much different from a screw in the prior art. To secure the LED module, this prior art requires six positioning rods connected to the LED assembly in various directions. Moreover, the positioning rods are very small and easily dropped or lost.

[0026] To address the aforementioned problems, this application provides a lighting fixture, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 3 As shown, it includes:

[0027] The lamp body 1 has at least two fixing posts 4;

[0028] Light source component 2, with corresponding through holes provided on it, is sleeved onto the fixing post 4 through the through holes;

[0029] The elastic fastener 3 has at least two abutting parts 30. Under the action of its own elastic restoring force, the elastic fastener 3 tends to deform so that the two abutting parts 30 abut against the two fixing posts 4, thereby fixing the light source assembly 2 on the fixing posts 4.

[0030] In the embodiments of this application, the lamp body 1 refers to the mechanical structure on the lamp fixture that supports or houses the light source assembly 2. See [link to relevant documentation]. Figure 1 As shown, it may include a housing 11, a panel 12, a lampshade 13, etc. The combination of these parts constitutes the shape of a lamp used in daily life.

[0031] The light source assembly 2 can be a light source based on various light-emitting principles such as LED, fluorescent lamp, or incandescent lamp. The light-emitting principle of the light-emitting body does not affect the realization of the technical objective of this application. In this application, a light source assembly 2 based on LED beads is used as an example for description. The through holes on the light source assembly 2 correspond one-to-one with the positions of each fixing post 4, so that the light source assembly 2 can be sleeved on the fixing post 4.

[0032] The elastic fastener 3 refers to a fastening device with a certain degree of elasticity that can cooperate with the fixing post 4 to abut or engage. It is usually made of a metal material with elastic restoring force. The elastic fastener can have various shapes and can be made according to the position and shape of the fixing post 4. Optionally, in this embodiment, the elastic fastener 3 is strip-shaped, with two abutting portions 30 respectively disposed at both ends of the elastic fastener 3.

[0033] In the existing technology, a flexible fastener 3 is required to fix each part of the light source component 2, which increases the number of parts. Moreover, the small-volume flexible fastener 3 requires more delicate operation, and its assembly and disassembly are more difficult.

[0034] The elastic fastener 3 provided in this embodiment can simultaneously support and fix two fixing posts 4, thus significantly reducing the number of elastic fasteners 3 required compared to the prior art. Furthermore, since it needs to support at least two fixing posts 4 respectively, the elastic fastener 3 can be designed as a long strip shape that is easy to grip and operate. Therefore, compared to the prior art, the elastic fastener 3 provided in this embodiment is not only less prone to falling during loading and unloading, but is also more convenient to operate.

[0035] For the elastic fastener 3 provided in this embodiment, the abutment portion 30 can have various forms, as long as it can achieve stable abutment contact with the fixing post 4. In addition, when the correct distance design is adopted, the panel 12 and the lampshade 13 of the lamp body 1 can simultaneously limit the elastic fastener 3, further improving the fixing stability.

[0036] Typically, the abutment portion 30 can be configured as a groove. The elastic fastener 3 is configured to tend to unfold into a straight strip. In this case, the user only needs to bend the elastic fastener 3 and insert it between the two fixing posts 4. After releasing it, the elastic fastener 3 will unfold to both sides under the action of elastic restoring force, so that the abutment portions 30 at both ends of the elastic fastener 3 press against the two fixing posts 4 respectively.

[0037] Alternatively, see Figure 4 , Figure 5 As shown, the contact portion 30 may include:

[0038] The abutment hole 31 is elongated and its length is greater than the radial width of the fixing post 4.

[0039] The fixing post 4 passes through the abutment hole 31 and abuts against the side wall of the abutment hole 31.

[0040] When the abutment hole 31 is provided, depending on the shape of the elastic fastener 3, both sides of the hole wall of the abutment hole 31 can be used as the actual part of the fixing post 4. Typically, if the elastic fastener 3 is initially in an unfolded state and tends to return to its flat unfolded state after being bent, the side wall of the abutment hole 31 near the center of the elastic fastener 3 will abut against the fixing post 4. Conversely, if the elastic fastener 3 is initially in a bent state and tends to return to its bent state after being flattened, the side wall of the abutment hole 31 near the outer side will abut against the fixing post 4. Considering that flattening the elastic fastener 3 is easier and easier to apply force than bending the flat elastic fastener 3, the latter is preferred in the embodiments of this application. At this time, under the action of its own elastic restoring force, the elastic fastener 3 tends to bulge in the direction away from the light source assembly 2.

[0041] To provide stronger friction, the contact area of ​​the elastic fastener 3 in contact with the fixing post 4 should be as large as possible. Therefore, optionally, the shape of the abutment hole 31 on the side abutting against the fixing post 4 matches the shape of the fixing post 4. When the two match, the force on the fixing post 4 can be more stable, preventing the elastic fastener 3 from slipping off.

[0042] This application also provides an improved method for increasing friction. Specifically, see [link to relevant options]. Figure 4 , Figure 5 As shown, a spring 32 that is raised toward the direction away from the light source assembly 2 is connected to the other side of the abutment hole 31, and the spring 32 abuts against the fixing post 4.

[0043] When the spring 32 is provided, the sidewalls of the spring 32 and the abutment hole 31 rely on the elastic restoring force of the spring 32 itself and the elastic fastener 3 body to abut against both sides of the fixing post 4, thus further preventing the elastic fastener 3 from falling off the fixing post 4.

[0044] Alternatively, the edge of the elastic fastener 3 abuts against the light source assembly 2, and the part of the elastic fastener 3 that contacts the light source assembly 2 is provided with a rounded corner 33.

[0045] When the edge of the elastic fastener 3 abuts against the light source assembly 2, the rounded corner 33 allows the elastic fastener 3 to slide along the surface perpendicular to the light source assembly 2, which can protect the light source assembly 2 and make the installation of the elastic fastener 3 more convenient.

[0046] The embodiments of this application also provide an installation method for the light source assembly 2 based on the above-described preferred configuration, as follows:

[0047] 1. See Figure 1 As shown, the light source assembly 2 is fitted onto the fixing post 4 of the lamp body 1.

[0048] 2. See Figure 3 , Figure 4 As shown, align the abutment hole 31 of the elastic fastener 3 (which is in a bent state by default) with the fixing post 4 and insert it, then press the elastic fastener 3 downwards. Since the rounded corner 33 of the fastener is pressed against the surface of the light source assembly 2 at this time, the elastic fastener 3 will unfold under pressure, and at the same time accumulate elastic potential energy.

[0049] 3. During the unfolding of the elastic fastener 3, the fixing post 4 pushes the spring 32 open and makes the spring 32 abut against the side wall of the fixing post 4.

[0050] 4. See Figure 2 As shown, when pressure is stopped on the elastic fastener 3, with the release of elastic potential energy, the elastic fastener 3 will return to its bent state under the action of its own elastic restoring force. Affected by this, the side wall of the abutment hole 31 will tightly abut against the side wall of the fixing post 4, while at the same time the spring 32 will also maintain abutment against the other side wall of the fixing post 4. In this way, the light source assembly 2 can be firmly fixed to the lamp body 1.

[0051] 5. When it is necessary to remove the light source assembly 2, press the elastic fastener 3 again. After the elastic fastener 3 deforms and unfolds, keep the elastic fastener 3 in its deformed state with one hand, and use the other hand to make the abutment hole 31 move away from the fixing post 4, so that the elastic fastener 3 can be removed smoothly.

[0052] Compared with the prior art, the flexible fixing structure provided by the embodiments of this application has the characteristics of saving time and effort, being easy to disassemble and assemble, and being low in cost.

[0053] Implementation Method 2

[0054] The second embodiment of this application provides a lamp fixture, which is a further improvement on the lamp fixture of the first embodiment. The main improvement is that, in the second embodiment of this application, see [link to relevant documentation]. Figure 6 As shown, there are at least four abutting portions 30, which are respectively disposed at the four corners of the elastic fastener 3. In this case, the elastic fastener 3 can be a hollow plate-like shape.

[0055] When using an elastic fastener 3 with four or more abutment portions 30, the installation of the light source assembly 2 can be completed by installing the elastic fastener 3 only once, which simplifies the installation and disassembly operations to the greatest extent.

[0056] Furthermore, four or more abutment portions 30 respectively fix the four corners of the light source assembly 2, forming a constraint between them, which can better prevent the individual abutment portions 30 from falling off. Moreover, when more than four abutment portions 30 are used, it is also easier for the front panel 12 of the lamp body 1 or the lamp cover 13 to limit the elastic fixing member 3, increasing the fixing stability.

[0057] Implementation Method 3

[0058] The third embodiment of this application provides a lamp fixture, which is a further improvement on the lamp fixture of the first or second embodiment. The main improvement is that, in the third embodiment of this application, see [link to relevant documentation]. Figure 7 As shown, each fixing post 4 is provided with a snap-fit ​​part; the two abutting parts 30 of the elastic fixing member 3 snap-fit ​​with the two snap-fit ​​parts respectively to fix the light source assembly 2 on the fixing post 4.

[0059] The snap-fit ​​part can take various forms, as long as it facilitates the snap-fit ​​of the elastic fastener 3 onto the fixing post 4. Specifically, the snap-fit ​​part can be a number of teeth arranged along the length of the fixing post 4. Using a toothed structure has the advantages of easy processing and low cost. At the same time, the multiple teeth also facilitate adjustment of the tightness of the elastic fastener 3. Besides a toothed structure, a hook-shaped structure or a rough surface / protrusion structure are also feasible.

[0060] Alternatively, the fixing post 4 can be a stud, meaning the snap-fit ​​part can be threaded. Using a standard stud instead of other non-standard fixing structures can significantly save costs. Furthermore, since the stud is fixed to the lamp body 1 during maintenance and repair, it does not need to be removed, thus not affecting maintenance efficiency. Of course, the fixing post 4 can also be integrally molded onto the lamp body 1, further simplifying the assembly steps during production.

[0061] Compared with the prior art, the implementation of this application increases the friction between the elastic fastener 3 and the fixed post 4 by setting a snap-fit ​​part, which can achieve better fixation and positioning.

[0062] It should be understood that the terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0063] It should be understood that although terms such as first, second, third, etc., may be used to describe certain components in the embodiments of this application, these components should not be limited to these terms alone. These terms are only used to distinguish the components from each other. For example, without departing from the scope of the embodiments of this application, a first component may also be referred to as a second component, and similarly, a second component may also be referred to as a first component.

[0064] In the embodiments of this application, terms such as "generally equal to," "generally perpendicular to," and "generally symmetrical" mean that the macroscopic size or relative positional relationship between the two features is very close to the stated relationship. However, those skilled in the art will understand that due to the existence of objective factors such as errors and tolerances, the positional relationship of objects is difficult to be precisely constrained at a small scale or even a microscopic angle. Therefore, even if there are slight errors in the size or positional relationship between the two, it will not have a significant impact on the realization of the technical effect of this application.

[0065] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0066] Finally, it should be noted that those skilled in the art will understand that many technical details have been presented in the embodiments of this application to facilitate a better understanding of the present application. However, even without these technical details and various changes and modifications based on the above embodiments, the technical solutions claimed in the claims of this application can be substantially achieved. Therefore, in practical applications, various changes can be made to the above embodiments in form and detail without departing from the spirit and scope of this application.
