Description

Technical Field

[0001] This utility model belongs to the field of LED lighting technology, specifically relating to a ceiling light. Background Technology

[0002] Ceiling lights are a type of lighting fixture. As the name suggests, they are called ceiling lights because the top of the fixture is relatively flat and the bottom is completely flush with the ceiling during installation. Light sources include ordinary incandescent bulbs, fluorescent lamps, high-intensity discharge lamps, halogen lamps, and LEDs; currently, LED ceiling lights are the most popular among consumers. Ceiling lights mainly consist of a base, a light source, and a lampshade. The light source is usually fixed to the base, which is then secured to the ceiling with expansion screws. After connecting the power cord, the lampshade is detachably installed on the base. Currently, most lampshades are detachably installed on the base using side screws or clips. However, this method inevitably has the following problems: 1. There is no accurate feedback on whether the lampshade is installed correctly, making it difficult to determine if the installation is reliable; 2. The clip structure lacks limiting positions, making it easy for the lampshade to loosen due to the lack of limiting positions; 3. To reduce packaging volume, ceiling lights are often packaged as a single assembly with the lampshade. This means that the base and lampshade need to be separated before installation. However, the smooth surface of the current base makes it difficult to grip, making separation difficult; 4. There is a lack of indicators, requiring multiple attempts to align the lampshade during installation to achieve the correct installation position. Summary of the Invention

[0003] The purpose of this utility model is to provide a ceiling light that addresses the problems existing in the background technology.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] A ceiling light includes a base and a lampshade. The base includes a base plate and an annular seat located on the side of the base plate opposite to its mounting surface. A resilient buckle is radially protruding from the outer circumference of the annular seat. Multiple resilient buckles are symmetrically arranged centrally. Each resilient buckle includes an resilient limiting body and a limiting portion. The end of the resilient limiting body adjacent to the limiting portion encloses a limiting region a between the resilient limiting body and the limiting portion. The resilient limiting body includes an elastic segment and a limiting segment sequentially from its inlet end inwards. The elastic segment has a guiding surface on its side facing the base plate, and the guiding surface extends continuously from the inlet end towards the limiting segment. The minimum distance between the limiting segment and the base plate is less than the minimum distance between the guiding surface and the base plate. The distance between the limiting segment and the base plate increases rapidly from its minimum distance position towards the side adjacent to the limiting region a.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the base plate has at least two concave areas symmetrically arranged on its mounting surface, and gripping pieces are arranged in the concave areas.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the concave area is spherical; the gripping piece is located in the middle of the concave area and is sheet-shaped.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the base plate is provided with directional markings on the end face opposite to its mounting surface and on the lampshade.

[0009] The outstanding and beneficial technical effect of this utility model compared with the prior art is as follows: By setting an elastic buckle, a locking post is set on the inner circumferential surface of the lampshade. After the lampshade is aligned with the direction indicator and fastened to the base, and the lampshade is rotated, the locking post will enter the limiting section through the guide surface and squeeze the limiting section to cause elastic deformation. The distance between the limiting section of the elastic buckle and the base plate is set to increase rapidly from its minimum distance position to the side adjacent to the limiting area a. The locking post contacts the lowest position of the elastic buckle, that is, the minimum distance position between the limiting section of the elastic buckle and the base plate. At this time, the elastic buckle undergoes maximum deformation. As the lampshade continues to rotate, the distance to the limiting area a increases. Then, after the elastic buckle passes this point, it instantly loses support and will be under the action of elastic force. The lamp holder quickly returns to its initial shape, generating vibration and a "click" sound to indicate that it is installed correctly. Due to this elastic buckle structure, the locking post is confined within the limiting area 'a'. After installation, a significant amount of force is required to rotate the lampshade to loosen or remove it, effectively preventing the lamp from falling due to vibration, heat, or deformation. Furthermore, the recessed area and gripping piece make the lamp holder easy to grip, facilitating disassembly of the lamp holder and lampshade before installation. Additionally, the directional indicator clearly shows the alignment position, allowing for quick and easy alignment in one go, solving the problem of traditional lampshades requiring multiple alignment attempts during installation.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0017] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0018] See details Figure 1-5 As shown, this application discloses a ceiling light, including a base 10 and a lampshade 20. Specifically, in conjunction with... Figure 1-3 as well as Figure 5As shown, in this embodiment, the base 10 includes a base plate 11 and an annular seat 12 located on the side of the base plate 11 opposite to its mounting surface. The base plate 11 has a wire hole 111 in the middle for passing the power cord from the junction box on the wall into the lamp and connecting it to the driver of the light source to supply power. In addition, the base plate 11 is also provided with screw mounting holes 112 and a power cord connector fixing seat 14. The screw passes through the screw mounting hole 112 and is screwed into the expansion plug or other mounting support provided on the wall. The power cord connector is embedded in the power cord connector fixing seat 14 for positioning and fixing, which facilitates wiring and ensures electrical installation. The outer circumferential surface of the annular seat 12 has radially protruding elastic buckles 13; multiple elastic buckles 13 are centrally symmetrically arranged; each elastic buckle 13 includes an elastic limiting body 131 and a limiting part 132. The end of the elastic limiting body 131 adjacent to the limiting part 132 and the limiting part 132 enclose a limiting area a. The elastic limiting body 131 includes an elastic segment 131a and a limiting segment 131b sequentially from the inlet end inward. The elastic segment 131a has a guide surface on the side facing the base plate 11. The guide surface extends continuously from the inlet end to the limiting segment 131b. The minimum distance between the limiting segment 131b and the base plate 11 is less than the minimum distance between the guide surface and the base plate 11. The distance between the limiting segment 131b and the base plate 11 increases rapidly from its minimum distance position towards the side adjacent to the limiting area a. Of course, to avoid the sidewall of the annular seat 12 affecting the movement of the elastic buckle 13, this embodiment preferably provides a reasonable clearance area at the location of the elastic buckle 13, that is, the annular seat 12 on the side of the elastic buckle 13 is partially hollowed out to allow for flexible movement of the elastic buckle 13. In this embodiment, the base 10 is preferably integrally injection molded. See... Figure 4 As shown, an annular lamp opening 21 is provided at the opening of the lampshade 20, and a cylindrical retaining post 22 is provided on the inner circumferential surface of the annular lamp opening 21. See Figure 5As shown in the figure, the dotted line illustrates the state of the locking post 22 during the locking process. By setting an elastic buckle, a locking post is provided on the inner circumference of the lampshade. After aligning the lampshade with the indicated direction and fastening it onto the base, rotating the lampshade causes the locking post to enter the limiting section via the guide surface and compress the limiting section, causing it to elastically deform. The distance between the limiting section and the base plate of the elastic buckle rapidly increases from its minimum distance position towards the side adjacent to the limiting area a. The locking post contacts the lowest position of the elastic buckle, i.e., the minimum distance position between the limiting section and the base plate of the elastic buckle. At this point, the elastic buckle engages... Maximum deformation: As the lampshade continues to rotate, the distance to the limiting area a increases. The elastic buckle loses support instantly after passing this point and quickly returns to its initial shape under the action of elastic force. This causes vibration and produces a "click" sound, indicating that the installation is in place. It is precisely because of this structure of the elastic buckle that the locking post is restricted within the limiting area a. After installation, a large force is required to rotate the lampshade to loosen it or remove it. This effectively prevents the lamp body from falling off due to shaking, heat, and deformation.

[0019] Furthermore, to reduce packaging volume, ceiling lights are often packaged together with the lampshade. This necessitates separating the base from the lampshade before installation. However, current bases have smooth surfaces that are difficult to grip, making separation difficult. To address this issue, in this embodiment, the base plate 11 preferably has at least two symmetrically arranged recessed areas 15 on its mounting surface, with gripping pieces 115 within each recessed area 15. Specifically, the recessed areas 15 are preferably spherical, and the gripping pieces 115 are located in the center of each recessed area 15 and are sheet-like. Preferably, the distance between the two recessed areas 15 is within the gripping range of an adult's thumb and middle finger. Thus, during disassembly, the base 10 can be gripped by placing the thumb and middle finger within the recessed areas 15; alternatively, the base 10 can be gripped by pinching the gripping pieces 115 with the thumb and forefinger.

[0020] Furthermore, existing lamp installations require multiple attempts and adjustments to the lampshade's position and alignment to achieve the desired installation location; therefore, in this embodiment, the base plate 11 preferably has directional markings on both the end face opposite to its mounting surface and on the lampshade 20. As shown in Figure 1, a first directional marking 113, shaped like a raised arrow, is located on the end face of the base 10 opposite to its mounting surface. Figure 4As shown, the arrow-shaped second direction indicator on the lampshade 20 allows for quick alignment and installation between the lampshade 20 and the base 10 by aligning the second direction indicator with the first direction indicator 113. Therefore, the direction indicator clearly indicates the alignment position, enabling alignment and quick installation in one go, solving the problem of traditional lampshades requiring multiple alignment attempts during installation.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
