For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] like Figure 1 , Figure 2 As shown, an embodiment of the present invention relates to a lighting fixture, which includes a light-emitting module 100, a heat sink 200, a main board 300, and a fixing buckle 400.

[0043] Combination Figure 2 and Figure 3 The light-emitting module 100 includes a bracket 110 and a light-emitting component 120 disposed on the bracket 110.

[0044] Understandably, bracket 110 is used to provide a mounting position for light-emitting component 120.

[0045] Combination Figure 3 and Figure 9 Furthermore, the light-emitting component 120 includes a circuit board 121, a light source 122 disposed on the circuit board 121, and a spring pin 140 disposed on the circuit board 121.

[0046] Specifically, the light source 122 is an LED, which is attached to the circuit board 121 and electrically connected to the circuit board 121; it is flexibly set on the circuit board 121 and electrically connected to the circuit board 121; under the conductive effect of the circuit board 121, the spring pin 140 can be electrically connected to the light source 122.

[0047] like Figure 3 As shown, the circuit board 121 further includes a central hole 1211, and the LED is disposed on the circuit board 121 such that the LED bead is located within the central hole 1211. The light emitted by the LED bead can propagate outward through the central hole 1211 of the circuit board 121.

[0048] Furthermore, the bracket 110 includes a mounting plate 112, which has a light-passing hole 1121. The circuit board 121 is attached to the mounting plate 112, and the light source 122 is positioned facing the light-passing hole 1121; wherein, for example... Figures 7 to 9 As shown, the light-emitting module 100 also includes a cover plate 130, which is disposed on the side of the circuit board 121 away from the mounting plate 112 and connected to the mounting plate 112. The cover plate 130 is used to fix the light-emitting component 120 to the mounting plate 112.

[0049] It should be noted that the arrangement of the light source 122 toward the light-passing hole 1121 can mean that the light source 122 is not placed in the light-passing hole 1121, or it can extend at least partially into the interior of the light-passing hole 1121.

[0050] like Figure 6 As shown, the motherboard 300 is mounted on the heatsink 200, which can dissipate heat from the motherboard 300.

[0051] Combination Figure 3 and Figure 6 Furthermore, the fixing clip 400 is set on the heat sink 200 and clips the motherboard 300, thus fixing the motherboard 300.

[0052] Specifically, the retaining clip 400 is attached to the outer edge of the motherboard 300, and the retaining clip 400 and the heat sink 200 can be fixedly connected by bolts or clips.

[0053] like Figure 3 As shown, the bracket 110 is further engaged with the fixing buckle 400, thereby electrically connecting the light-emitting component 120 to the motherboard 300.

[0054] Specifically, the fixing buckle 400 fastens the bracket, thereby causing the spring pin 140 on the light-emitting component 120 to abut against the motherboard 300, thus electrically connecting with the motherboard 300. In this way, the motherboard 300 can be electrically connected to the light source 122 to control the light-emitting effect of the light source 122.

[0055] like Figure 3As shown, the motherboard 300 and the light-emitting component 120 are arranged side by side, with the motherboard 300 located behind the light-emitting component 120. The motherboard 300 has a through hole 310, which is arranged opposite to the light-emitting component 120. At least a portion of the heat sink 200 passes through the through hole 310 and is attached to the light-emitting component 120, so that the heat sink 200 can dissipate heat from the light-emitting component 120.

[0056] Combination Figure 4 and Figure 5 In some embodiments, the fixing buckle 400 is provided with an arc-shaped slot 411, and the bracket 110 is provided with a fastening part 111. The fastening part 111 is rotatably fastened in the arc-shaped slot 411 and electrically connects the light-emitting component 120 to the motherboard 300. The bracket 110 is configured to rotate so that the fastening part 111 disengages from the arc-shaped slot 411 so that the light-emitting module 100 can be disassembled.

[0057] Specifically, the fixing buckle 400 has a snap-fit ​​portion 410, which is arc-shaped and has an arc-shaped groove 411. The snap-fit ​​portion 111 snaps into the arc-shaped groove 411, thereby connecting the bracket 110 and the fixing buckle 400. Furthermore, by rotating the bracket 110, the snap-fit ​​portion 111 can be disengaged from the arc-shaped groove 411. At this time, the bracket 110 and the fixing buckle 400 are disconnected, and the light-emitting module 100 can be disassembled.

[0058] In this invention's lighting fixture, if the light-emitting component 120 is damaged or needs to be replaced, the bracket 110 can be rotated to disengage the fastening part 111 from the arc-shaped slot 411, thereby removing the light-emitting module 100 and then installing a new light-emitting module 100. Installing a new light-emitting module 100 is simple; just screw the fastening part 111 into the arc-shaped slot 411.

[0059] like Figure 6 As shown, the motherboard 300 further includes an arc-shaped conductive terminal 320 on the side near the spring pin 140. The arc-shaped conductive terminal 320 is coaxially arranged with the arc-shaped slot 411. The spring pin 140 abuts against the arc-shaped conductive terminal 320, and the arc-shaped conductive terminal 320 is located on the rotation path of the spring pin 140.

[0060] It is understandable that the arc-shaped conductive terminal 320 is used to bring out the circuit inside the motherboard 300. When the spring pin 140 abuts against the arc-shaped conductive terminal 320, the motherboard 300 can be electrically connected to the light source 122.

[0061] It should be noted that during the installation of the light-emitting module 100, because the arc-shaped conductive terminal 320 is arc-shaped and coaxially arranged with the arc-shaped slot 411, the spring pin 140 will move along the arc-shaped conductive terminal 320. Even if there is an error in the rotation angle of the light-emitting module 100 relative to the motherboard 300 during final installation, the spring pin 140 can still contact the arc-shaped conductive terminal 320. Furthermore, the contact between the spring pin 140 and the arc-shaped conductive terminal 320 can be achieved during the installation of the light-emitting module 100, making assembly simple.

[0062] Combination Figure 3 and Figure 5 Furthermore, the arc-shaped slot 411 has a snap-fit ​​wall 4111, the bracket 110 is supported on the main board 300, and the snap-fit ​​part 111 abuts against the snap-fit ​​wall 4111.

[0063] Specifically, the side of the motherboard 300 near the light-emitting component 120 is used to directly or indirectly support the bracket 110, so that the fastening part 111 abuts against the snap-fit ​​wall 4111, thereby fixing the light-emitting module 100.

[0064] Combination Figure 4 and Figure 5 Furthermore, the fixing buckle 400 is provided with a mounting and dismounting port 420 at the entrance of the arc-shaped slot 411 for the fastening part 111 to move in a direction perpendicular to the main board 300.

[0065] Understandably, when installing the light-emitting module 100, the fastening part 111 can be aligned with the mounting / removing port 420, and then the light-emitting module 100 can be moved toward the motherboard 300, so that the fastening part 111 is aligned with the entrance of the arc-shaped slot 411. Then, the light-emitting module 100 can be rotated so that the fastening part 111 is rotated into the arc-shaped slot 411 and engaged with the fixing buckle 400. When removing the light-emitting module 100, the light-emitting module 100 can be rotated first so that the fastening part 111 is rotated out of the entrance of the arc-shaped slot 411, and then the light-emitting module 100 can be moved away from the motherboard 300 through the mounting / removing port 420 to remove it.

[0066] Combination Figure 5 and Figure 6 Furthermore, the snap-fit ​​wall 4111 includes a guide surface 4111a and a limiting surface 4111b connected to the guide surface 4111a. The guide surface 4111a is located on the side of the limiting surface 4111b near the mounting / removing port 420. The guide surface 4111a gradually moves away from the motherboard 300 in a direction that gradually moves away from the limiting surface 4111b.

[0067] It is understandable that when installing the light-emitting module 100, the fastening part 111 can be aligned with the mounting / removing port 420. Since the guide surface 4111a is inclined and gradually moves away from the main board 300 along the direction of gradually moving away from the limiting surface 4111b, the entrance of the arc-shaped slot 411 can be larger, thus facilitating the fastening part 111 to be screwed into the arc-shaped slot 411 and abut against the limiting surface 4111b.

[0068] Combination Figure 1 and Figure 2 It should be noted that the luminaire also includes a lens 500 disposed in front of the light-emitting component 120 and a reflector 600 disposed in front of the lens 500; it should be noted that both the lens 500 and the reflector 600 are detachable structures.

[0069] Specifically, the lens 500 is detachably connected to the bracket 110, and the front end of the lamp is provided with a face cover 700. The reflector 600 is detachably connected to the face cover 700. Thus, the light-emitting module 100 can be replaced after the bracket 110 and the face cover 700 are removed.

[0070] The lens 500 and the bracket 110 can be detachably connected by snap-fit ​​or threaded connection; the faceplate 700 and the reflector 600 can be detachably connected by snap-fit ​​or threaded connection.

[0071] In this lamp, the light-emitting module 100 includes a bracket 110 and a light-emitting component 120 disposed on the bracket 110. The bracket 110 provides an installation position for the light-emitting component 120. A mainboard 300 is disposed on a heat sink 200, which dissipates heat from the mainboard 300. A fixing buckle 400 is disposed on the heat sink 200 and holds the mainboard 300 in place, thus securing the mainboard 300. The fastening part 111 engages with the arc-shaped slot 411, connecting the bracket 110 and the fixing buckle 400. If the light-emitting component 120 is damaged or needs replacement, the bracket 110 can be rotated in the disassembly direction, causing the fastening part 111 to disengage from the arc-shaped slot 411, thereby disassembling the light-emitting module 100 before installing a new light-emitting module 100. When installing a new light-emitting module 100, it is only necessary to screw the fastening part 111 into the arc-shaped slot 411, making installation simple. In the lamp of this utility model, the replacement of the light-emitting module 100 can be facilitated, reducing waste.
