Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, and in particular relates to an LED lamp. Background Technology

[0002] In related technologies, the proportion of LED light sources in LED lighting fixtures using LED filaments for assembly is gradually increasing. However, currently, LED filaments in LED lighting fixtures are generally soldered onto an electrode bus, which prevents the flexible and rapid fabrication of LED light sources of different lengths. Instead, the length of the electrode bus needs to be customized according to the required length of the LED light source before the LED filament is soldered onto that electrode bus, making the process complex. LED light sources need to be prefabricated in the factory and then transported to the site for installation, making it impossible to flexibly and quickly adjust the required length and lumen output of the LED light source on-site according to actual lighting needs. Utility Model Content

[0003] The purpose of this application is to provide an LED lighting fixture that solves the problem that LED light sources using LED filaments cannot be flexibly and quickly adjusted in terms of length and lumens according to actual lighting needs on site.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: An LED lamp includes a housing assembly, two end caps, an LED light source assembly, and two connecting terminals.

The inner side wall of the side plate is provided with a fourth slot, and the two electrode components are respectively embedded in the two fourth slots.

[0009] In some embodiments, the housing assembly further includes two side conditions, each side condition having a snap-fit ​​rib and a hook.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0051] like Figures 1 to 7 The image shows an LED lamp provided according to Embodiment 1 of this application. The LED lamp of Embodiment 1 includes a housing assembly 10, two end caps 40, an LED light source assembly 20, and two connecting terminals 30. Two end caps 40 are respectively fitted onto both ends of the housing assembly 10. The housing assembly 10 includes a first light-emitting wall 111 and a second light-emitting wall 112. The first light-emitting wall 111 and the second light-emitting wall 112 are arranged opposite to each other. The housing assembly 10 and the two end caps 40 enclose a receiving cavity 11. The first light-emitting wall 111 and the second light-emitting wall 112 are the bottom wall and the top wall of the receiving cavity 11, respectively. The LED light source assembly 20 is housed in the receiving cavity 11. The LED light source assembly 20 includes two electrode components 21 and multiple LED filaments 22. When the multiple LED filaments 22 are energized and emit light, light is emitted from at least the first light-emitting wall 111 and the second light-emitting wall 112 for illumination. That is, the light emitted from the first light-emitting wall 111 illuminates downwards, and the light emitted from the second light-emitting wall 112 illuminates upwards. Two electrode elements 21 are spaced apart on the inner walls of the receiving cavity 11. Multiple LED filaments 22 are spaced apart along the extension direction of the electrode elements 21. The two ends of each LED filament 22 are detachably connected to the two electrode elements 21 to form a parallel connection, meaning that the multiple LED filaments 22 are energized in parallel, thus ensuring that the luminous power of each LED filament 22 is consistent. Two connecting terminals 30 are located in the receiving cavity 11 and are electrically connected to the two electrode elements 21 respectively.

[0052] The LED filament 22 is a light-emitting element composed of multiple LED chips connected in series or parallel on a transparent or semi-transparent substrate (such as ceramic, glass, or sapphire) and coated with silicone resin adhesive. This allows for uniform light dispersion, and the uniform yellow phosphor layer in the silicone resin adhesive converts the blue light emitted by the LED chips into white light of the desired color temperature. Thus, the light emitted by the LED filament 22 can simultaneously illuminate downwards from the first light-emitting wall 111 and upwards from the second light-emitting wall 112.

[0053] In the LED lamp of Embodiment 1, multiple LED filaments 22 are arranged in parallel at intervals along the extension direction of the electrode 21. Each LED filament 22 has two ends detachably connected to two electrode 21s. Thus, the LED light source assembly 20 can flexibly adjust the number of LED filaments 22 on-site according to the required lumens for actual lighting, allowing for direct on-site adjustment. Furthermore, the length of the electrode 21 can be cut on-site to the required length, ensuring that the length of the electrode 21 matches the number of LED filaments 22. Moreover, the first light-emitting wall 111 and the second light-emitting wall 112 can also be cut on-site to fit the length of the electrode 21. This allows for convenient, quick, and flexible on-site adjustment of the LED light source assembly 20.

[0054] like Figures 2 to 4 , Figure 6 As shown, the housing assembly 10 of the LED lamp in Embodiment 1 of this application further includes a frame 12. The frame 12 includes a first side plate 121 and a second side plate 122. The first side plate 121 and the second side plate 122 are connected at intervals to form a first light outlet 123 and a second light outlet 124. Specifically, a plurality of spaced connecting strips are provided between the sides of the first side plate 121 and the second side plate 122 that form the second light outlet 124. The plurality of connecting strips connect the first side plate 121 and the second side plate 122 at intervals. The first side plate 121 and the second side plate 122 are each provided with a first slot 125, a second slot 126, and a third slot 127. The two sides of the first light-emitting wall 111 are respectively engaged with the two first slots 125 and located at the first light-emitting port 123. The two sides of the second light-emitting wall 112 are respectively engaged with the two third slots 127 and located at the second light-emitting port 124. The two electrode components 21 are respectively embedded in the two second slots 126. The two end caps 40 are respectively installed at both ends of the frame 12 (the end caps 40 are preferably snapped onto the ends of the frame 12; of course, the end caps 40 can also be further locked onto the ends of the frame 12 by screws). In this LED lamp, the assembly between the frame 12, the first light-emitting wall 111, the second light-emitting wall 112, and the two end caps 40 can all be directly assembled by snapping without the need for screw locking, which not only has high assembly efficiency but also facilitates subsequent disassembly and maintenance. The first light-emitting wall 111, the second light-emitting wall 112, the first side plate 121, the second side plate 122, and the two end caps 40 enclose and form a receiving cavity 11, with the first light-emitting wall 111 and the second light-emitting wall 112 serving as the bottom and top walls of the receiving cavity 11, respectively. Furthermore, the frame 12 can be cut to fit the lengths of the electrode 21, the first light-emitting wall 111, and the second light-emitting wall 112 according to actual needs. After the frame 12 is cut, the first side plate 121 and the second side plate 122 are still connected by several connecting strips located on the side of the second light-emitting wall 112 facing away from the receiving cavity 11. Of course, the frame 12 of the LED lamp can also be customized according to the actual requirements of the site without cutting. Correspondingly, the first light-emitting wall 111, the second light-emitting wall 112 and the two electrode components 21 also do not need to be cut. At this time, the number of LED filaments 22 can be flexibly adjusted on site according to the actual lumen required for lighting. The end cap 40 is locked to the end of the frame 12 with screws.

[0055] In the LED lamp of Embodiment 1, the electrode component 21, which has a certain length, is prone to bending, making it inconvenient to insert into the second slot 126 and affecting assembly efficiency. Therefore, as Figures 2 to 7As shown, the LED light source assembly 20 also includes two rigid mounting strips 23. Two electrode members 21 are respectively secured to the two mounting strips 23, preventing the electrode members 21 from easily bending. The mounting strips 23 are then inserted into the second slot 126. Each mounting strip 23 has multiple notches corresponding to a plurality of LED filaments 22. The ends of the LED filaments 22 pass through the corresponding notches and are electrically connected to the electrode members 21. Furthermore, as... Figure 3 , Figure 5 and Figure 7 As shown, the connecting terminal 30 is locked onto the mounting strip 23 by screws 34 and electrically connected to the electrode 21.

[0056] like Figure 2 and Figure 3 As shown, in an LED lamp according to Embodiment 1, the electrode component 21 includes a body 211 and multiple sets of hooks 212. The body 211 serves as a support carrier for the electrode component 21 and determines its length. The multiple sets of hooks 212 are used to detachably install multiple LED filaments 22 one-to-one to achieve electrical connection. That is, the multiple sets of hooks 212 are spaced apart along the extension direction of the body 211, and the ends of multiple LED filaments 22 are clamped one-to-one with the multiple sets of hooks 212. The clamping is completed simply by passing the end of the LED filament 22 through the notch of the mounting strip 23 and pressing it into the corresponding hook 212, resulting in high assembly efficiency.

[0057] like Figure 6 and Figure 7 As shown, in another LED lamp of Embodiment 1, the electrode 21 includes a body 211 and multiple elastic sheets 213. The body 211 serves as a support carrier for the electrode 21, determining its length. The multiple elastic sheets 213 are used to achieve electrical connection with multiple LED filaments 22 in a one-to-one correspondence. That is, the multiple elastic sheets 213 are spaced apart along the extension direction of the body 211, and the ends of the multiple LED filaments 22 abut against the elastic sheets 213 in a one-to-one correspondence. By simply passing the end of the LED filament 22 through the notch in the mounting strip 23, the end of the LED filament 22 can abut against the corresponding elastic sheet 213 to achieve electrical connection, resulting in high assembly efficiency. The notch also restricts the end of the LED filament 22, preventing it from shifting.

[0058] like Figure 4 and Figure 5As shown, in another LED lamp of Embodiment 1, the electrode 21 is a metal strip, which can be cut to any length to obtain the electrode 21 of the required length. Furthermore, the electrode 21 is bent into multiple spaced recesses 214, and the ends of multiple LED filaments 22 are clamped into the recesses 214 one-to-one to achieve electrical connection. The clamping is completed simply by passing the end of the LED filament 22 through the notch of the mounting strip 23 and pressing it into the corresponding recess 214, resulting in high assembly efficiency.

[0059] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the LED lamp in Embodiment 1 also includes a driver module 50 and two mounting brackets 90. The two mounting brackets 90 are respectively connected to connecting strips near their ends on the frame housing 12. That is, one end of the mounting bracket 90 is fixedly connected to the frame housing 12, and the other end of the mounting bracket 90 is fixedly mounted to a fixed mounting part (e.g., a ceiling). Therefore, the LED lamp is a pendant lamp suspended from the fixed mounting part by the two mounting brackets 90. The mounting bracket 90 has a hollow channel that communicates with the receiving cavity 11. The driver module 50 is located outside the receiving cavity 11, and the connecting cable 52 of the driver module 50 passes through the hollow channel and is electrically connected to the connecting terminal 30.

[0060] like Figures 8 to 11 The LED lamp shown is provided in Embodiment 2 of this application. This LED lamp has the following differences from the LED lamp provided in Embodiment 1.

[0061] like Figures 9 to 11 As shown, in the LED lamp of Embodiment 2, side plates 113 are provided on both sides of the first light-emitting wall 111 and / or the second light-emitting wall 112. The first light-emitting wall 111 and the second light-emitting wall 112 are covered, and two end caps 40 are inserted into the two ends of the first light-emitting wall 111 and the second light-emitting wall 112 respectively to form a cavity 11. Furthermore, the inner sidewalls of the two side plates 113 are provided with fourth slots 114, and the two electrode components 21 are respectively embedded in the two fourth slots 114. This LED lamp is described with the example of side plates 113 on both sides of the first light-emitting wall 111. The first light-emitting wall 111 and the side plates 113 on both sides are integrally formed, so the two side plates 113 can also transmit light for illumination. That is, the light emitted by the LED filament 22 can be transmitted through the first light-emitting wall 111, the second light-emitting wall 112 and the two side plates 113 for illumination. Furthermore, the LED lamp is securely assembled by inserting two end caps 40 into the two ends of the first light-emitting wall 111 and the second light-emitting wall 112 respectively. The assembly is carried out through a purely mechanical structure, without the need for screw locking, which results in high assembly efficiency and facilitates subsequent disassembly and maintenance.

[0062] To ensure a more secure fit between the first light-emitting wall 111 and the second light-emitting wall 112, such as Figures 8 to 11 As shown, the housing assembly 10 also includes two side conditions 13. The side conditions 13 are provided with snap-fit ​​ribs 131 and hooks 132. The first light-emitting wall 111 has side uprights 113 on both sides. The outer side wall of the side uprights 113 is provided with snap-fit ​​grooves 115. The second light-emitting wall 112 is provided with hook grooves 116. The hooks 132 are hooked into the hook grooves 116 and the snap-fit ​​ribs 131 are snapped into the snap-fit ​​grooves 115. In this way, the two side conditions 13 pull and restrict the first light-emitting wall 111 and the second light-emitting wall 112, so that the first light-emitting wall 111 and the second light-emitting wall 112 are stably covered by each other. Furthermore, the two ends of the two side conditions 13 are respectively inserted into the two end caps 40, or the two ends of the two side conditions 13 respectively abut against the end faces of the opening ends of the two end caps 40. The two end caps 40 prevent the side conditions 13 from sliding along their extension direction and disengaging from the first light-emitting wall 111 and the second light-emitting wall 112, ensuring that the side conditions 13 always restrict the first light-emitting wall 111 and the second light-emitting wall 112. The side conditions 13 can be made of non-metallic materials, such as transparent or translucent acrylic materials. Furthermore, the non-metallic side conditions 13 and the first light-emitting wall 111 and the second light-emitting wall 112 can be made of the same material, in which case the side conditions 13 can also transmit light for illumination; or, the side conditions 13 can also be made of metallic materials, in which case the side conditions 13 cannot transmit light.

[0063] like Figure 9 and Figure 11 As shown, the LED lamp in Embodiment 2 also includes a driver module 50 and a power cable 60. The driver module 50 is installed inside one of the end covers 40, as shown. Figure 11 As shown, the end cap 40 has sliding grooves 46 on its opposite side walls. The two sides of the circuit board of the drive module 50 are respectively inserted into the two sliding grooves 46 for stable installation. Both connection terminals 30 are electrically connected to the drive module 50. The drive module 50 has a first plug 51, and the power cable 60 is connected to the second plug 61. The end cap 40 has a through hole 43, wherein the through hole 43 of the end cap 40 that houses the drive module 50 is directly opposite the first plug 51, and the second plug 61 is inserted into and connected to the first plug 51 through the through hole 43. Furthermore, the through hole 43 of the other end cap 40 is covered by a sealing member 45 to seal the through hole 43 and prevent debris, dust, and moisture from entering the receiving cavity 11 through the through hole 43.

[0064] The LED light fixture also includes two slings 80, which are fixedly connected to two end caps 40 respectively. Both slings 80 are used to fix the light fixture to the fixed mounting part (such as the ceiling). Thus, the LED light fixture is a hanging light fixture that is suspended from the fixed mounting part by the two slings 80.

[0065] Compared with the LED lamp of Embodiment 1, the LED lamp of Embodiment 2 is identical in all aspects except for the above-mentioned structural differences, and will not be described again here.

[0066] like Figures 12 to 16 The LED lamp shown is provided in Embodiment 3 of this application. This LED lamp has the following differences from the LED lamps provided in Embodiment 1 / Embodiment 2.

[0067] like Figure 15 and Figure 16 As shown, in the LED lamp provided in Embodiment 3, both connecting terminals 30 include a terminal body 31 and a first insertion portion 32 and a second insertion portion 33 spaced apart from each other on the terminal body 31. Figures 13 to 16 As shown, the end cap 40 is provided with two first insertion holes 41 and two second insertion holes 42. Both first insertion holes 41 penetrate the top side surface of the end cap 40, and both second insertion holes 42 penetrate the end side surface of the end cap 40. Two first insertion portions 32 correspond to the two first insertion holes 41 respectively, and two second insertion portions 33 correspond to the two second insertion holes 42 respectively. Figure 12 As shown, the LED lamp also includes a driver module 50, which can be located outside the receiving cavity 11. The connecting cable 52 of the driver module 50 can be electrically connected to two connecting terminals 30 through the first plug-in hole 41 or the second plug-in hole 42 to form a circuit. Specifically, two opposing clamping bent pieces are stamped on the first plug-in part 32 and the second plug-in part 33. The openings of the two clamping bent pieces of the first plug-in part 32 face the first plug-in hole 41, and the openings of the two clamping bent pieces of the second plug-in part 33 face the second plug-in hole 42. When the end of the connecting cable 52 passes through the first plug-in hole 41 or the second plug-in hole 42, the end of the connecting cable 52 is inserted between the two clamping bent pieces, clamped and fixed, and an electrical connection is achieved.

[0068] like Figure 12 As shown, the LED lamp in Embodiment 3 also includes two slings 80, which are fixedly connected to two end caps 40 respectively. Specifically, the slings 80 are inserted into the lifting holes 47 of the end caps 40 for slinging. Furthermore, both slings 80 are used for fixed connection to a fixed mounting part (e.g., a ceiling), thus the LED lamp is a pendant lamp suspended from the fixed mounting part by the two slings 80. In this case, the connecting cable 52 is preferably inserted from the first plug hole 41 and electrically connected to the first plug part 32.

[0069] Alternatively, in the LED lamp of Embodiment 3, the driving module 50 can be installed in one of the end caps 40. The driving module 50 is electrically connected to the two electrode pieces 21 by wires. The two terminal bodies 31 are electrically connected to the driving module 50. The external power line can be electrically connected to the two connecting terminals 30 through the first plug hole 41 or the second plug hole 42 to form a circuit.

[0070] Compared with the LED lamps of Embodiment 1 / Embodiment 2, the LED lamps of Embodiment 3 are identical in all aspects except for the above-mentioned structural differences, and will not be described again here.

[0071] like Figures 17 to 20 The LED lamp shown is provided in Embodiment 4 of this application. This LED lamp has the following differences from the LED lamp provided in Embodiment 3.

[0072] like Figures 17 to 20 As shown, the LED lamp also includes a slot housing 70, which is used to mount to a fixed mounting part. Specifically, the slot housing 70 includes a slot body 71, a first end plate 72, and a second end plate 73. The first end plate 72 and the second end plate 73 are respectively connected to the two ends of the slot body 71 to form an assembly space 75 with an opening 74. The inner wall surface of the slot housing 70 facing the opening 74 is a reflective surface 76, and the walls of the first end plate 72 and the second end plate 73 facing the assembly space 75 are provided with protrusions 77. Furthermore, each of the two end caps 40 has a mounting groove 44 on its end side. The mounting groove 44 includes a connected entry groove section 441 and a mounting groove section 442. The entry groove section 441 penetrates the top side surface of the end cap 40. During assembly, the protrusions 77 slide into the mounting groove section 442 through the entry groove section 441, so that the components such as the housing assembly 10, the LED light source assembly 20, and the end caps 40 are mounted and stably mounted on the protrusions 77 of the slot housing 70 under the action of gravity. When the LED filament 22 emits light, the first light-emitting wall 111 transmits light downwards for direct illumination, and the second light-emitting wall 112 faces the reflective surface 76. The second light-emitting wall 112 transmits light upwards and illuminates the reflective surface 76. The reflective surface 76 reflects the light downwards and mixes it with the light transmitted by the first light-emitting wall 111 to achieve mixed lighting.

[0073] Furthermore, in the LED lighting fixture provided in Embodiment 4, such as Figures 17 to 19 As shown, the drive module 50 is located outside the receiving cavity 11. The connecting cable 52 of the drive module 50 can be electrically connected to the two connecting terminals 30 through the first insertion hole 41 or the second insertion hole 42 to form a circuit. Specifically, the connecting cable 52 passes through the wire hole 78 on the first end plate 72 or the second end plate 73 into the assembly space 75. Since the second insertion hole 42, which passes through the end side of the end cover 40, is opposite to the wire hole 78 and is short in distance, the end of the connecting cable 52 preferably passes through the second insertion hole 42 and is inserted into the second insertion part 33 to achieve electrical connection. Of course, the end of the connecting cable 52 passing through the wire hole 78 can also be inserted into the first insertion part 32 through the first insertion hole 41 to achieve electrical connection.

[0074] Alternatively, in the LED lamp of Embodiment 4, the driving module 50 can be installed in one of the end caps 40. The driving module 50 is electrically connected to the two electrode pieces 21 by wires. The two terminal bodies 31 are electrically connected to the driving module 50. The external power line enters the assembly space 75 through the wire hole 78 and then connects to the two connecting terminals 30 through the first insertion hole 41 or the second insertion hole 42 to form a circuit.

[0075] Compared with the LED lamp of Embodiment 3, the LED lamp of Embodiment 4 is identical in all aspects except for the above-mentioned structural differences, and will not be described again here.

[0076] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
