Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of lighting fixtures, and more specifically, it relates to a screwless downlight. Background Technology
[0002] Currently, most downlights on the market use elastic springs or spring clips as ceiling clips in their installation and fixing structure design, and are connected to the light fixture body by screws. Springs and spring clips are two different installation accessories, allowing users to choose one based on ceiling thickness, installation space, and other requirements. Specifically, after selecting a spring or spring clip, the user needs to fix it to the plastic mounting base of the light fixture with screws to achieve a snap-fit fixation to the ceiling.
[0003] However, this traditional screw fastening method has significant drawbacks: on the one hand, during the screwing process into the plastic parts, structural damage such as cracking and deformation of the plastic parts is easily caused by improper torque control, insufficient toughness of the plastic material, or unreasonable screw hole design. Especially during long-term use, the probability of damage to the plastic parts is further increased due to factors such as vibration and temperature changes. On the other hand, tools are required to tighten the screws during disassembly. If the screws are stripped or the screw holes of the plastic parts are worn, disassembly will be difficult, seriously affecting the convenience of maintenance and replacement efficiency of the lamps. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a screwless downlight, which has the advantages of being screwless, easy to install and easy to disassemble.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a screwless downlight, comprising: The outer casing serves as the mounting base; An electric light source is installed inside the housing; A lampshade is provided over the opening of the outer casing; The mounting position is located on the outer wall of the housing, and a card interface is provided on the side of the mounting position away from the housing; The mounting component is inserted into the mounting position to allow the entire lamp to be snapped into place with the outside. The pin is inserted into the mounting position through the card interface and engages with the mounting component.
[0006] In one embodiment, the pin includes a insert, a baffle disposed at one end of the insert, and a protrusion disposed at the other end of the insert; The bottom of the mounting position is provided with a locking block. The insert and the protrusion are both located in the mounting position. The insert is inserted into the card interface and passes through the mounting piece. The protrusion is engaged with the locking block.
[0007] In one embodiment, one side of the locking block has an inclined portion that cooperates with the protrusion for slidingly engaging the protrusion.
[0008] In one embodiment, a first limiting block is provided on one side of the mounting position near the outer casing, and a second limiting block is provided on the other side. Both the first limiting block and the second limiting block are used to restrict the horizontal movement of the mounting component within the mounting position.
[0009] In one embodiment, the insert is further provided with a limiting groove, which engages with the first limiting block.
[0010] In one embodiment, the electric light source includes a light source board and a lamp holder wire. The light source board is installed inside the housing, and one end of the lamp holder wire is connected to the light source board, while the other end extends through the housing. A wire clip is provided through the top of the housing, and the end of the lamp head wire away from the light source board passes through the wire clip and is located on the housing.
[0011] In one embodiment, an aluminum cup is also provided inside the housing. The housing is made of thermally conductive plastic and is connected to the aluminum cup by an insert injection molding process. The mounting position and the outer shell are integrally molded.
[0012] In one embodiment, the mounting element is a spring or a clip.
[0013] In one embodiment, the number of mounting positions, mounting parts, and pins is the same, and each is no less than two.
[0014] The aforementioned screwless downlight has the following beneficial effects: Firstly, the mounting component and the mounting position are connected by a pin, eliminating the need for screw drilling and making the installation of the entire light convenient. When the entire light needs to be removed from the ceiling or other locations, the connection between the mounting component and the mounting position can be released simply by using the pin, allowing the entire light (excluding the mounting component) to be removed, and then the mounting component can be removed from the external fastener.
[0015] Secondly, the outer shell is made of thermally conductive plastic, and the aluminum cup is directly embedded in the outer shell during injection molding. Therefore, the aluminum cup can be made thinner in terms of process, saving production costs. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0020] Furthermore, 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 number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, unless otherwise explicitly specified.
[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0022] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature. Example 1
[0023] A screwless downlight, such as Figure 1 and Figure 2 As shown, it includes a housing 1, an electric light source 2, a lampshade 3, a mounting position 4, a mounting component 5, and a pin 6. The housing 1 serves as the mounting base, the electric light source 2 is installed inside the housing 1, the lampshade 3 covers the opening of the housing 1, the mounting position 4 is installed on the outer wall of the housing 1, and a snap-fit interface 41 is provided on the side of the mounting position 4 away from the housing 1. The mounting component 5 is inserted into the mounting position 4 to snap the entire lamp into the outside. The pin 6 is inserted into the mounting position 4 through the snap-fit interface 41 and snaps into the mounting component 5.
[0024] Based on the above design, the advantage of this embodiment is that the mounting component 5 and the mounting position 4 are engaged by the pin 6, which facilitates the installation of the entire lamp. There is no need to drill screw holes in the outer shell 1, avoiding structural damage such as cracking or deformation of the outer shell 1 (a risk that may exist when the outer shell 1 is made of plastic). When the entire lamp needs to be removed from the ceiling or other locations, the engagement between the mounting component 5 and the mounting position 4 can be released simply by using the pin 6, and the entire lamp except for the mounting component 5 can be removed. Then, the mounting component 5 can be removed from the external fastener. Therefore, whether it is installation or disassembly, there is no high requirement for the user's operational proficiency, which meets the modern standard of convenient lamp installation.
[0025] like Figure 2-4As shown, the pin 6 includes a insert 61, a baffle 62 installed at one end of the insert 61, and a protrusion 63 installed at the other end of the insert 61. A locking block 42 is provided at the bottom of the mounting position 4. Both the insert 61 and the protrusion 63 are located within the mounting position 4. The insert 61 is inserted into the card interface 41 and passes through the mounting member 5. The protrusion 63 is engaged with the locking block 42. In this embodiment, both the insert 61 and the protrusion 63 are within the mounting position 4. The insert 61 is inserted into the card interface 41 and passes through the mounting member 5, thereby confining the mounting member 5 within the mounting position 4 and engaging it. Furthermore, the engagement of the protrusion 63 with the locking block 42 within the mounting position 4 ensures a secure connection between the pin 6 and the mounting position 4.
[0026] like Figure 2-4 As shown, one side of the locking block 42 is provided with an inclined portion 421 that cooperates with the protrusion 63 for sliding engagement with the protrusion 63. In this embodiment, in order to enable the pin 6 to be flexibly inserted and removed at the mounting position 4, the inclined portion 421 specially provided on the locking block 42 can cooperate with the protrusion 63 and slide against each other, ultimately keeping the pin 6 and the mounting position 4 in a sliding engagement.
[0027] like Figure 2-4 As shown, a first limiting block 43 is provided on one side of the mounting position 4 near the outer casing 1, and a second limiting block 44 is provided on the other side. Both the first limiting block 43 and the second limiting block 44 are used to restrict the horizontal movement of the mounting component 5 within the mounting position 4. A limiting groove is also provided on the insert 61, and the limiting groove engages with the first limiting block 43. In this embodiment, the engagement of the limiting groove with the first limiting block 43 ensures that the horizontal movement of the pin 6 itself within the mounting position 4 is also restricted.
[0028] like Figure 1 As shown, the electric light source 2 includes a light source board 21 and a lamp holder wire 22. The light source board 21 is installed inside the housing 1. One end of the lamp holder wire 22 is connected to the light source board 21, and the other end is installed through the housing 1. A wire clip 11 is installed through the top of the housing 1. The end of the lamp holder wire 22 away from the light source board 21 passes through the wire clip 11 and is installed on the housing 1.
[0029] An aluminum cup is also provided inside the outer shell 1. The outer shell 1 is made of thermally conductive plastic and is connected to the aluminum cup by an insert injection molding process. The mounting position 4 and the outer shell 1 are integrally molded. The mounting part 5 is a spring or a spring clip. The number of mounting positions 4, mounting parts 5 and pins 6 are the same, and there are no fewer than 2 of each.
[0030] In this embodiment, because the mounting position 4, mounting part 5 and pin 6 are connected by a snap-fit method, there is no need to drill holes or screws on the outer shell 1. Furthermore, the outer shell 1 can be made of thermally conductive plastic (drilling holes in thermally conductive plastic materials carries the risk of cracking and is not suitable for screws, but it has excellent thermal conductivity), which is more cost-effective than the conventionally chosen material PC for the outer shell 1 of the downlight. The outer shell 1 is connected to the aluminum cup by a snap-fit process through an insert injection molding process. The aluminum cup is directly inserted into the outer shell 1 during injection molding, and the aluminum cup can be made thinner, which can save costs. Example 2
[0031] The differences between Example 2 and Example 1 are as follows: Specifically, such as Figure 5 As shown, the mounting component 5 in Embodiment 2 is specifically a spring (the mounting component 5 in Embodiment 1 is a spring sheet, and the two have different adaptability to the installation environment).
[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
