[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 4According to an embodiment of the present invention, a surface-mounted downlight that is easy to assemble and disassemble includes a fixing base 100 and a lamp body 200. The fixing base 100 is provided with an external mounting structure 110; one of the lamp body 200 and the fixing base 100 is provided with a mounting groove 120, and the other is provided with a clamping block 310. The mounting groove 120 is connected to an inlet and outlet channel 130. The clamping block 310 is clamped in the mounting groove 120 to fix the lamp body 200 to the fixing base 100. By rotating the lamp body 200, the clamping block 310 can enter and exit the mounting groove 120 through the inlet and outlet channel 130; wherein, one of the groove wall of the mounting groove 120 and the clamping block 310 is provided with a positioning protrusion 140, and the other is provided with a positioning clamping groove 311. The positioning protrusion 140 is clamped in the corresponding positioning clamping groove 311. During the rotation of the lamp body 200 , when the positioning protrusion 140 abuts against the groove wall of the positioning slot 311 , the positioning protrusion 140 and the groove wall of the installation slot 120 can elastically expand and contract relative to each other, so that the positioning protrusion 140 enters and exits the positioning slot 311 .

[0032] In a specific implementation, one or more of the following configurations can be employed: the positioning protrusion 140 is elastically extendable; the walls of the positioning slot 311 are elastically extendable; the walls of the mounting slot 120 are elastic; or the retaining block 310 is elastic. Thus, when the lamp body 200 is rotated with a certain amount of force, when the positioning protrusion 140 and the walls of the positioning slot 311 come into contact with each other, the positioning protrusion 140 and the walls of the positioning slot 311 can elastically extend relative to each other, thereby allowing the positioning protrusion 140 to enter and exit the positioning slot 311.

[0033] Specifically, in some embodiments, the fixing plate and the clamping block 310 can be made of a material with a certain degree of toughness, such as plastic or rubber, and the fixing plate and the clamping block 310 themselves have a certain degree of elastic deformation. Of course, in other embodiments, the fixing plate and the clamping block 310 can also be made of a material with a higher hardness, so that the fixing plate and the clamping block 310 are less likely to elastically deform. In this case, the positioning protrusion 140 can be configured in the form of a spring-loaded bead, that is, the positioning protrusion 140 is slidably mounted on the clamping block 310 or the groove wall of the installation groove 120, and the positioning protrusion 140 is equipped with a spring that drives the positioning protrusion 140 to slide back. Therefore, when the positioning protrusion 140 and the groove wall of the positioning clamping slot 311 abut each other, the positioning protrusion 140 can elastically expand and contract relative to the groove wall of the installation groove 120. In addition, the positioning protrusion 140 can also be made of a material with good elasticity, such as silicone or rubber, so that the positioning protrusion 140 can elastically expand and contract relative to the groove wall of the installation groove 120.

[0034] The surface-mounted downlight provided by the present invention has a fixing base 100 that can be fixed to an external object such as a wall or ceiling using an external mounting structure 110. When installing the lamp body 200, first insert the clamping block 310 installed on the lamp body 200 into the inlet and outlet channel 130, and then spend a certain amount of force to rotate the lamp body 200 so that the clamping block 310 enters the mounting groove 120. During this process, the positioning protrusion 140 and the groove wall of the corresponding positioning groove 311 can be elastically moved relative to each other, so that the positioning protrusion 140 is clamped in the corresponding positioning groove 311, and then the clamping connection between the positioning protrusion 140 and the groove wall of the positioning groove 311 is used to generate resistance. The resistance to the rotation of the lamp body 200 is reduced, thereby positioning the block 310 and making the lamp body 200 more securely mounted on the fixing base 100. This effectively reduces the risk of the lamp body 200 automatically rotating due to wind or other factors when no one is rotating it, causing the lamp body 200 to fall. To remove the lamp body 200, simply rotate the lamp body 200 in the opposite direction with some force, disengaging the positioning protrusion 140 from the positioning slot 311. The block 310 then moves from the mounting slot 120 to the access channel 130, and the lamp body 200 can be removed. This makes the lamp body 200 easy to assemble and disassemble, and the lamp body 200 is securely mounted. In addition, if the block 310 or the mounting slot 120 becomes worn due to repeated disassembly and replacement of the lamp body 200, the positioning protrusion 140 and the positioning slot 311 prevent the block 310 from becoming loose within the mounting slot 120.

[0035] In some embodiments, one of the above-mentioned mounting grooves 120 can be provided, and one block 310 can be provided correspondingly. At this time, the mounting groove 120 can be provided in the middle position of the fixing seat 100 , and the outer contour of the mounting groove 120 is circular, and the block 310 is provided at one end of the lamp body 200 .

[0036] Reference Figure 1 and Figure 4 According to some embodiments of the present invention, at least two mounting slots 120 are provided, all of which are distributed circumferentially. At least two clamping blocks 310 are provided, corresponding one-to-one with all of the mounting slots 120. Therefore, during installation of the lamp body 200, each clamping block 310 can be first inserted into a corresponding access channel 130. Then, when the lamp body 200 is rotated, each clamping block 310 can be inserted into a corresponding mounting slot 120 through a corresponding access channel 130. This arrangement allows the lamp body 200 to be more securely mounted on the fixing base 100 through the cooperation between the at least two clamping blocks 310 and the at least two mounting slots 120.

[0037] Reference Figure 5 and Figure 6According to some embodiments of the present invention, one of the retaining block 310 and the wall of the mounting slot 120 is provided with a positioning protrusion 140, while the other is provided with at least two positioning slots 311. All positioning slots 311 are distributed circumferentially, and the center of the positioning slots 311 coincides with the center of the mounting slot 120. Thus, the positioning protrusion 140 can be positioned in any two or more positioning slots 311 located in the same mounting slot 120 as the positioning protrusion 140, thereby achieving positioning of the lamp body 200 at different rotational angles. In other words, the installation angle of the lamp body 200 can be adjusted within a certain range.

[0038] Reference Figure 3 、 Figure 5 and Figure 6 According to some embodiments of the present invention, the end of the positioning protrusion 140 close to the positioning slot 311 is hemispherical, and the two opposite groove walls of the positioning slot 311 close to the end of the positioning protrusion 140 are semi-cylindrical. With the above arrangement, when people rotate the lamp body 200, the positioning protrusion 140 can move in and out of the positioning slot 311 more smoothly.

[0039] Reference Figure 3 、 Figure 4 and Figure 6 According to some embodiments of the present invention, the mounting groove 120 is provided on the fixing base 100, and the block 310 is connected to a connecting block 320 on one side facing the lamp body 200, and the connecting block 320 is detachably connected to the lamp body 200, wherein the bottom wall of the mounting groove 120 is provided with an avoidance hole 150, and the avoidance hole 150 is communicated with the inlet and outlet channel 130, and the avoidance hole 150 is used to avoid the corresponding connecting block 320, and the block 310 and the lamp body 200 can cooperate with each other to be clamped on the bottom wall of the mounting groove 120, so that the lamp body 200 can be stably installed on the fixing base 100, reducing the degree of shaking of the lamp body 200 due to external airflow, vibration and other factors.

[0040] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, the connecting block 320 is detachably connected to the lamp body 200 via bolts or a snap-fit ​​structure. The connecting block 320 and the clamping block 310 can be integrally formed, thus allowing the clamping block 310 to be replaced within the lamp body 200. In practice, the shape of the mounting slot 120 on the mounting base 100 may vary due to differences in design, manufacturer, and other factors. In this case, the lamp body 200 can be replaced with a clamping block 310 of a matching shape to allow the lamp body 200 to be mounted on the mounting base 100.

[0041] Reference Figure 1 、 Figure 4According to some embodiments of the present invention, a receiving groove 211 is provided at one end of the lamp body 200, and the fixing base 100 is located in the receiving groove 211. Therefore, after the lamp body 200 is installed on the fixing base 100, the lamp body 200 can cover and hide the fixing base 100, making the appearance of the entire downlight more ornamental.

[0042] Reference Figure 1 、 Figure 2 and Figure 4 According to some embodiments of the present invention, a wire hole 160 is provided in the middle of the fixing base 100 to allow the lamp body 200 to be connected to an external wire. With this arrangement, the lamp body 200 can hide the wires, making the appearance of the entire downlight more ornamental.

[0043] Reference Figure 1 and Figure 4 According to some embodiments of the present invention, an operating hole 170 is formed on the fixing base 100, and the operating hole 170 is located on one side of the wire hole 160. In a specific implementation process, when the surface-mounted downlight is shipped from the factory, the lamp body 200 is usually installed on the fixing base 100 through the cooperation between the above-mentioned installation groove 120 and the clamping block 310. When the user purchases the surface-mounted downlight and installs it, it is necessary to first separate the fixing base 100 from the lamp body 200. The provision of the above-mentioned operating hole 170 can facilitate the user to operate the fixing base 100 to rotate relative to the lamp body 200 so as to separate the fixing base 100 from the lamp body 200. After the fixing base 100 and the lamp body 200 are separated, the fixing base 100 is fixed to a wall, ceiling or other external object, and finally the lamp body 200 is installed on the fixing base 100 through the cooperation between the above-mentioned installation groove 120 and the clamping block 310.

[0044] Reference Figure 1 and Figure 4 The external mounting structure 110 includes at least two screw mounting holes 111 distributed around the wire hole 160. Thus, the mounting base 100 can be fixed to a wall, ceiling, or other external object using two or more screws. Specifically, one end of the screw passes through the screw mounting hole 111 and is screwed to the wall or ceiling, while the other end of the screw abuts the mounting base 100, thereby pressing the mounting base 100 against the wall or ceiling.

[0045] It is conceivable that in other embodiments, the external mounting structure 110 may also include Velcro.

[0046] Reference Figure 2According to some embodiments of the present invention, the lamp body 200 includes a lamp housing 210 and a lighting device 220. The lamp housing 210 is provided with a mounting cavity 212 on a side facing away from the fixing base 100. The lighting device 220 is installed in the mounting cavity 212. Thus, the lamp body 200 can be illuminated from the side facing away from the fixing base 100.

[0047] Reference Figure 2 The first and second step structures 2221 are used to fix the inner wall of the lamp body 200 so as to prevent the outer wall from being damaged.

[0048] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
