In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of these features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.
[0031] In the description of the present invention, it should be noted that the terms "installation", "connected" and "connected" should be understood in a broad sense, unless otherwise clearly specified and limited. For example, they can be fixed or detachable. Connected or integrally connected; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication between two components. For those of ordinary skill in the art, the specific meaning of the above-mentioned terms in the present invention can be understood through specific situations.
[0032] Reference attached Figure 1~5 , An LED surface mounted downlight in this embodiment includes a lampshade 1, a light source plate 2, a lamp body 3, a sheath wire 5, and a mounting bracket 4 from top to bottom, where "up" and "down" versus figure 1 The upper and lower positions in the middle position correspond to each other. The "upper" and "lower" in this embodiment are only for ease of description, but do not indicate or imply that they have a specific position and are constructed in a specific position; lampshade 1, light source plate 2, and sheath The cable 5 and the mounting bracket 4 can be detachably installed on the lamp body 3. The specific structure is as follows:
[0033] The lamp body 3 has a groove, and the inner side wall of the groove has a second buckle 33 that cooperates with the light source plate 2. The second buckle 33 is bent inward to abut against the light source plate 2, and the light source plate 2 passes through the second buckle. The buckle 33 is clamped in the groove so as to be detachably installed on the lamp body 3. The second buckle 33 is located above the light source plate 2. In this embodiment, the number of the second buckle 33 is two, two The second buckles 33 are symmetrically arranged on the inner side wall of the groove.
[0034] The side wall of the groove has a through hole 31. One end of the sheath wire 5 is located in the groove and is electrically connected to the light source board 2, and the other end can pass through the through hole 31 to extend out of the lamp body 3. There is also a first buckle 32 at the bottom of the lamp body 3, and one end of the sheath wire 5 is located in the lamp body 3 and is locked in the first buckle 32, so as to be detachably installed on the lamp body 3; and the sheath wire 5 is located in the lamp body 3. One end of the body 3 has a stop 51 for blocking the sheath wire 5 from passing through the through hole 31. In this embodiment, the outer diameter of the stop 51 is larger than the diameter of the through hole 31, so that the stop 51 cannot pass through The through hole 31 penetrates, and in practical applications, it can also be blocked by a structure such as a block, which is determined by those skilled in the art according to the actual situation. Through the stopper 51 and the first buckle 32, the sheath wire 5 can be clamped in the lamp body 3, the connection is firm, and the certification tensile test can be passed.
[0035] In this embodiment, the first buckle 32 is located between the two second buckles 33 and is at 90° from the two second buckles 33. The light source board 2 has a side wall extending in the axial direction and penetrating the side wall. The opening 21 is adapted to the first buckle 32, so that when the light source board 2 is installed, the positioning function of the opening 21 and the first buckle 32 can facilitate the installation of the light source board 2 in the groove.
[0036] The lampshade 1 is installed above the light source board 2. The lampshade 1 has a lampshade clamping block 11, and the lamp body 3 has a clamping slot 34 matched with the lampshade clamping block 11, and the lampshade 1 is clamped in the clamping slot 34 by the lampshade clamping block 11. It can be detachably installed on the lamp body 3; the inner wall of the lamp body 3 also has a limit block 35, which is located below the slot 34, so that the lamp cover 1 is located above the slot 34, and the bottom of the lamp cover 1 is connected to The tops of the limit blocks 35 abut against each other. By the limit of the limit blocks 35, on the one hand, the lampshade 1 can be prevented from falling into the groove of the lamp body 3, and on the other hand, the lampshade 1 can be positioned and supported when the lampshade 1 is installed. Function, easy to install the lampshade 1.
[0037] Both ends of the mounting bracket 4 have bracket blocks 41 protruding outward, and the inner wall of the lamp body 3 has fasteners 36 that cooperate with the bracket blocks 41. In this embodiment, the fasteners 36 are elastic, and The mounting bracket 4 is detachably mounted on the lamp body 3 through the abutment and fit of the bracket clamping block 41 and the fastener 36. The inner wall of the lamp body 3 also has a mounting bracket 4 for restricting The limiting portion 37 for lateral movement, which is located on both sides of the fastener 36, can prevent the lateral movement of the mounting bracket 4 from causing the bracket block 41 and the fastener 36 to be damaged. The problem of the lamp body 3 falling off.
[0038] In this embodiment, both the lamp body 3 and the mounting bracket 4 are made of plastic materials, which can solve the mold cost and material cost issues.
[0039] When assembling the downlight in this embodiment, it is only necessary to place the light source plate 2 in the groove of the lamp body 3, and fix the light source plate 2 through the second buckle 33 to complete the installation of the light source plate 2; One end of the sheath wire 5 passes through the through hole 31 to extend out of the lamp body 3, and the end of the sheath wire 5 located in the lamp body 3 is clamped in the first buckle 32, which completes the installation of the sheath wire 5; It is clamped in the slot 34 to complete the installation of the lamp cover 1; the two ends of the mounting bracket 4 are clamped on the fasteners 36 to complete the installation of the mounting bracket 4, the lamp cover 1, the light source board 2, and the sheath line 5 and the mounting bracket 4 and the lamp body 3 are all detachable buckle structure, no screw structure, assembly is very convenient and simple, can improve assembly efficiency, and has low manufacturing cost and simple preparation process. When the downlight needs to be disassembled, only the above-mentioned buckle needs to be opened, which is convenient and simple to disassemble, facilitates the maintenance of the inside of the downlight, and does not damage the structure of the downlight.
[0040] The above are only characteristic implementation examples of the present invention, and do not constitute any limitation to the protection scope of the present invention. All technical solutions formed by equivalent exchange or equivalent replacement fall within the protection scope of the present invention.
