[0044] See Figures 1-3 ,as well as Figure 9 One 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 snapped onto the base 110. The base 110 and the lampshade 150 together form a first cavity 101, and the base 110 and the mounting base 200 together form a second cavity 202. The second cavity 202 contains a driving power supply electrically connected to the light-emitting component 140. Specifically, the first cavity 101 is elongated and open at both ends, with a first end cap 160 disposed at each of the two open ends. The second cavity 202 is elongated and open at both ends, with a second end cap 203 disposed at each of the two open ends.

[0045] See Figures 4-7 At least one first end cap 160 is provided with a recess 300, and a sensor assembly is mounted in the recess 300. The sensor assembly includes a plug 510 (or socket) for electrically connecting to a circuit board 520, and a socket 311 (or plug) for electrically connecting to a drive power supply is provided on the corresponding first end cap 160 (specifically the recess 300). During assembly, the plug 510 and socket 311 cooperate to realize the electrical connection between the drive power supply and the sensor 530. The sensor 530 may be, but is not limited to, a radar sensor, an infrared sensor, etc.

[0046] The sensor assembly includes a protective cover 400, a circuit board 520 built into the protective cover 400, and a sensor 530 fixed to the circuit board 520 and exposed to the protective cover 400. The protective cover 400 fills the recess 300, and the surface of the protective cover 400 is flush with the surface of the corresponding first end cap 160. The recess 300 is understood to be lower than the surface of the protective cover 400.

[0047] In this embodiment, the sensor 530 is exposed to the protective cover 400, which helps to improve the detection range and sensitivity of the sensor 530. The sensor assembly is quickly and easily installed into the recess 300. The sensor assembly occupies minimal space in the recess 300, having little impact on the LED light-emitting surface. The protective cover 400 is flush with the first end cap, not affecting the overall shape and packaging of the LED light fixture. Its appearance is consistent with the light-emitting surface, ensuring the aesthetics of the LED light fixture and resulting in a harmonious overall effect.

[0048] The sensor assembly includes a housing 500 encapsulating a circuit board 520 and a sensor 530, with a connector 510 passing through the housing 500. A protective cover 400 has knockout holes 401 for mounting the sensor 530. When dealing with LED lights of the same model but from different batches, the protective cover 400 can be retained while the circuit board 520 and sensor 530 are removed. This can be achieved by discarding the housing 500, thus meeting different user needs while maintaining the aesthetics of the LED lights.

[0049] In some embodiments, the recess 300 has a horizontal wall 310 for mounting the positioning sensor assembly and a vertical wall 320 perpendicular to the horizontal wall 310, with a socket 311 provided on the corresponding horizontal wall 310. The horizontal wall 310 has a locking hole 312, and the protective housing has a latch 402 that mates with the locking hole 312. The locking holes 312 include two located on opposite sides of the horizontal wall 310, and the encapsulation housing 500 is mounted between the two locking holes 312. The horizontal plane provided by the horizontal wall 310 can be understood as parallel to the light-emitting surface, specifically parallel to the main body of the base in the corresponding embodiment. The LED lamp can be a strip lamp having a length direction and a width direction, with the locking holes 312 located on opposite sides of the strip lamp's width direction.

[0050] See Figure 7A hollow bolt 330 is fixed through and through the horizontal wall 310, and a socket 311 is installed and fixed in the hollow area of ​​the hollow bolt 330. This allows the socket 311 to pass through the hollow bolt 330 and extend into the second cavity 202 for electrical connection with the drive power supply. The hollow bolt 330 has a hollow bolt head 331 and a hollow cylinder 332 with external threads. The horizontal wall 310 has a through hole 313 for the hollow cylinder 332 to enter. The hollow cylinder 332 is clamped and fixed to the horizontal wall 310 after being engaged with a nut 334. The horizontal wall 310 has a countersunk groove 314 that matches the hollow bolt head 331.

[0051] See Figure 7 When the LED light fixture leaves the factory, the hollow cylinder 332 mates with the nut 334 to clamp and fix the socket 311, and the protective shell is snapped onto the horizontal wall 310. The hollow cylinder 332 extends into the second cavity 202. The protective cover 400 has a pre-drilled knockout hole 401.

[0052] See Figure 6 When assembling the sensor assembly, release the engagement between the clip 402 of the protective cover 400 and the locking hole 312 of the horizontal wall 310, and electrically connect the encapsulation housing 500 with the plug 510 to the socket 311. After the encapsulation housing 500 is in place, re-cover the protective cover 400, exposing the sensor 530 to the knockout hole 401. The protective cover 400, locked to the horizontal wall 310, holds the encapsulation housing 500 against the horizontal wall 310, preventing the encapsulation housing 500 from loosening and ensuring good electrical contact between the plug 510 and the socket 311.

[0053] See Figures 8-10 In some embodiments, the first end cap 160 and the second end cap 203 do not overlap. The mounting base 200 and the light-emitting module 100 each have a first cavity 101 and a second cavity 202, which are respectively shielded 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; the module can be quickly replaced through the snap-fit ​​connection between the base 110 and the mounting base 200.

[0054] In some embodiments, the base 110 of the light-emitting module 100 may be formed from a metal sheet. The base 110 includes a flat main body portion 120 and a side portion 130 that is folded away from the lampshade 150 relative to the main body portion 120. The main body portion 120 of the base 110 is used to fix the light-emitting assembly 140. A portion of the main body portion 120 has a stamped blocking portion 121 that is folded relative to the main body portion 120. The blocking portion 121 and the main body portion 120 form a mounting gap 122. The extended edge 152 of the lampshade 150 is placed within the mounting gap 122. 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. 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.

[0055] 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.

[0056] During the assembly of LED lamps, the mounting base 200 and the light-emitting component 140 are assembled separately, and then connected to the mounting base 200 through the engaging part 133, so that the base 110 and the mounting base 200 can be easily and detachably connected.

[0057] 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.

[0058] 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.

[0059] 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.
