[0042] See Figures 1-5One embodiment of this application provides an LED lamp fixture, which includes a mounting base 200 and a light-emitting module 100. The light-emitting module 100 includes a base 110 (e.g., formed from sheet metal), a light-emitting component 140 disposed on the surface of the base 110, and a lampshade 150 that engages with the base 110 to form a first cavity 101. The base 110 and the mounting base 200 engage to form a second cavity 202, and a driving power supply electrically connected to the light-emitting component 140 is disposed inside the second cavity 202. Specifically, the first cavity 101 is elongated and open at both ends, and a first end cap 160 is disposed at each of the two open ends. The second cavity 202 is elongated and open at both ends, and a second end cap 203 is disposed at each of the two open ends. The first end cap 160 and the second end cap 203 do not overlap each other.

[0043] In this embodiment, the mounting base 200 and the light-emitting module 100 each have a first cavity 101 and a second cavity 202, and the first cavity 101 and the second cavity 202 are respectively covered by the first end cap 160 and the second end cap 203. When installing or replacing the light-emitting module 100, the end caps do not need to be removed, and the light-emitting module 100 can be quickly replaced by snapping together the base 110 and the mounting base 200.

[0044] The light-emitting component 140 may be, for example, a light strip disposed on the main body 120. The light strip is fixed to the main body 120 by means of plastic screws. The light strip includes a substrate and LED beads disposed on the substrate. The lamp cover 150 includes a cover 151 and an extension edge 152 extending inward from the cover 151.

[0045] The base 110 of the light-emitting module 100 includes a flat main body 120 and a side portion 130 that is folded away from the lampshade 150 relative to the main body 120. The main body 120 of the base 110 is used to fix the light-emitting assembly 140. A portion of the main body 120 has a stamped blocking portion 121 that is folded relative to the main body 120, forming a mounting gap 122 with the blocking portion 121. The extended edge 152 of the lampshade 150 is placed within the mounting gap 122, and the side portion 130 of the base 110 of the light-emitting module 100 has a engaging portion 133 that connects to the mounting base 200.

[0046] In this embodiment, the lampshade 150 is detachably connected and fixed to the base 110 by placing the extended edge 152 of the lampshade 150 within the mounting gap 122, thus achieving rapid assembly. When the LED lamp is used as a strip light, the blocking part 121 includes two sets arranged side by side on both sides of the light-emitting component 140. The two sets of blocking parts 121 and the main body 120 respectively form two sets of mounting gaps 122 for placing the extended edge 152 of the lampshade 150. At this time, the two sets of mounting gaps 122 are functionally equivalent to mounting grooves. The lampshade 150 includes two sets of extended edges 152 extending inward from the cover 151. The extended edge 152 of the lampshade 150 can be slidably inserted between the blocking part 121 and the main body 120 along the two sets of mounting gaps 122 by a sliding fit, thereby achieving the connection and fixation of the lampshade 150 relative to the base 110.

[0047] In this embodiment, during the assembly of the LED lamp: the mounting base 200 and the light-emitting component 140 are assembled separately, and then connected to the mounting base 200 via the engaging part 133, allowing for a simple and detachable connection between the base 110 and the mounting base 200. In this embodiment, when the light-emitting module 100 changes to different lampshade 150 styles, for example... Figures 6-8 As shown, the use of square, oval, or round lampshades does not affect the disassembly and connection method between the base 110 and the mounting base 200. The mounting base 200 and the light-emitting module 100 are independent of each other. The shape of the first end cap 160 is adapted to the cross-section of the lampshade 150. For example, if the lampshade 150 is square, the first end cap 160 is adapted to be square. Before the mounting base 200 and the light-emitting module 100 are connected and fixed, they can be connected to each other by a safety rope. After connection and fixing, the safety rope is hidden inside the mounting base 200.

[0048] This embodiment simplifies the assembly of LED lights, enabling rapid assembly of the mounting base 200 and the light-emitting module 100. Furthermore, since the mounting base 200 is compatible with the base 110, the same model of mounting base 200 can be used with light-emitting modules 100 that have the same base 110 but different lampshades 150. This allows manufacturers to match the mounting base 200 to light-emitting modules 100 with popular lampshade styles, reducing inventory pressure on the mounting base 200.

[0049] See Figures 3-5In some implementations, the side portion 130 of the base 110 of the light-emitting module 100 prevents light leakage by means of a folded edge. The side portion 130 includes a first folded edge 134 formed by folding from the main body 120 away from the lampshade 150, and a second folded edge 135 formed by folding the first folded edge 134 twice. The second folded edge 135 is perpendicular to the main body 120 and has an engaging portion 133. The angles of the two folds are both less than 90 degrees and the sum is 90 degrees. The continuous folding of the first folded edge 134 and the second folded edge 135 reduces the possibility of light escaping to the outside of the lampshade 150. Furthermore, the edge of the cover 151 of the lampshade 150 abuts against and is flush with the second folded edge 135, thereby covering the first folded edge 134, resulting in a flat and aesthetically pleasing overall appearance of the LED lamp.

[0050] In some embodiments, the mounting base 200 includes a groove-shaped structure 201 formed from sheet metal, the groove-shaped structure 201 including a bottom wall 210 and a side wall 220. The side wall 220 of the groove-shaped structure 201 engages with the side portion 130 of the base 110 of the light-emitting module 100. The side portion 130 has an engaging portion 133, for example, a protrusion, and the side wall 220 of the groove-shaped structure 201 has a snap hole 221 that mates with the protrusion, so that the base 110 and the mounting base 200 together form a second cavity 202. Further, after the bottom wall 210 is folded once to form the side wall 220, the side wall 220 is folded a second time to form a constricted portion 240. The edge of the constricted portion 240 provides guidance for the side portion 130, facilitating the engagement and fixation of the light-emitting module 100 and the mounting base 200.

[0051] See Figure 9 In some embodiments, the main body 120 is equipped with a sensor 124, such as a radar sensor, an infrared sensor, a voice sensor, etc. The main body 120 has a mounting hole 123 for mounting the sensor 124. The mounting hole 123 can be a knock-out hole for the user to knock it off. The side of the sensor 124 facing the lampshade 150 is substantially flush with the main body 120.

[0052] See Figures 10-11 The sensor 124 can be installed using either the first or the second method to accommodate different sensors as needed. In the first method, the sensor 124 can be installed by having a barb 126 on it, and its size being larger than the mounting hole 123. The barb 126 is then engaged with the edge of the mounting hole 123 for fixation.

[0053] The second option: The edge of the mounting hole 123 is provided with a clamping ear 125 formed by stamping and extending away from the lampshade 150. The end of the clamping ear 125 is folded to form a limiting part 127 that cooperates with the main body 120 to fix the sensor 124. The sensor 124 itself can be provided with a U-shaped groove 128 for the clamping ear 125 to clamp. After the clamping ear 125 is placed into the U-shaped groove 128, the end of the clamping ear 125 forms the limiting part 127 through a sheet metal fold.

[0054] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0055] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
