Detailed implementation manners

[0058] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] Here, it should be noted that in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution of the present invention are shown in the drawings, while other details less related to the present invention are omitted.

[0060] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0061] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0062] Referring to Figures 1 to 21 , the lighting fixture 100 includes a power supply module 1, a light source module 2, a wiring structure 3, and a lighting fixture housing 4.

[0063] Preferably, the lighting fixture 100 is a street lamp. In other embodiments, the lighting fixture may also be other similar lamps.

[0064] The lighting fixture housing 4 includes: an electrical box 11, an end cap 41, and a frame 42.

[0065] In this embodiment, the electrical box 11 and the end cap 41 are connected by the frame 42, and the frame 42 is fixedly connected to the light source module 2. The setting of the frame 42 makes the structure of the lighting fixture 100 more stable and the installation workers safer during high-altitude operations. In other embodiments, the lighting fixture may not be provided with a frame.

[0066] In this embodiment, the electrical box 11 is used to install the power supply main body 12 in the power supply module 1, and both the electrical box 11 and the end cap 41 are fixedly connected to the wiring structure 3.

[0067] Furthermore, the end cap 41 and the electrical box 11 are respectively located at both ends of the wiring structure 3.

[0068] Specifically, the electrical box 11 includes: a wiring terminal 111, a housing 112, and a wiring cover 113.

[0069] The wiring terminal 111 is used to connect the first electrical part 116 and the second electrical part 117 and is provided on the wiring cover 113.

[0070] Among them, the first electrical part 116 is a wire that extends from the outside into the electrical box 11 and is connected to the terminal 111, and the second electrical part 117 is a wire that connects the terminal 111 and the light source module 2.

[0071] The housing 112 includes: an upper cover 1121 of the electrical box and a lower cover 1122 of the electrical box. A slot is provided inside the upper cover 1121 of the electrical box, and a rib extending toward the upper cover 1121 of the electrical box is provided inside the lower cover 1122 of the electrical box. The position of the rib corresponds to that of the slot. A first sealing ring 1128 is arranged in the slot, and the first sealing ring 1128 also surrounds above the rib. The upper cover 1121 of the electrical box and the lower cover 1122 of the electrical box achieve the waterproof sealing of the electrical box 11 through the first sealing ring 1128.

[0072] Furthermore, fastening screws are provided on the outer side of the rib. The upper cover 1121 of the electrical box and the lower cover 1122 of the electrical box are mechanically connected through the fastening screws. And during the process of tightening the fastening screws, the first sealing ring 1128 is subjected to the extrusion force of the rib and thus sinks into the slot, making the waterproof sealing effect of the electrical box 11 better.

[0073] In addition, an accommodation space 1123 for accommodating the terminal 111 is formed by surrounding the upper cover 1121 of the electrical box and the lower cover 1122 of the electrical box.

[0074] In this embodiment, a wiring port 1124 is opened on the upper cover 1121 of the electrical box. The orthographic projection of the wiring port 1124 is within the orthographic projection range of the upper cover 1121 of the electrical box and the lower cover 1122 of the electrical box. And, the wiring port 1124 and the wiring cover 113 are correspondingly arranged, and the wiring cover 113 and the wiring port 1124 are hermetically connected in an openable manner.

[0075] Thus, when the wiring cover 113 and the wiring port 1124 are hermetically connected, the terminal 111 provided on the wiring cover 113 can be reliably accommodated in the accommodation space 1123; when accessing the mains power, there is no need to open the upper cover 1121 or the lower cover 1122 of the electrical box, and by directly opening the smaller-area wiring cover 113, the terminal 111 is directly exposed, so that the wiring operation of the installation worker is convenient and labor-saving.

[0076] Furthermore, the wiring cover 113 and the wiring port 1124 are hermetically connected through a second sealing ring 1132.

[0077] Specifically, a groove 1126 is provided around the position of the wiring port 1124, and the second sealing ring 1132 is arranged in the groove 1126.

[0078] By providing a groove 1126 around the wiring port 1124, the risk of the second sealing ring 1132 falling off can be reduced and safety can be improved. Therefore, the risk of water entering the lamp when the second sealing ring 1132 is lost or reinstalled is reduced, thereby saving costs and improving the safety of the lamp.

[0079] In another embodiment, the wiring port 1124 may be arranged on the lower cover 1122 of the electrical box, the wiring cover 113 may be provided with a groove 1126 at a position corresponding to the wiring port 1124, and the second sealing ring 1132 may be arranged in the groove 1126. Similar to the solution of this embodiment, this embodiment also has the effects of convenient and labor-saving wiring operation for the installer, reduced cost, and improved safety of the lamp, which will not be described in detail here.

[0080] In this embodiment, the electrical box 11 further includes an anti-dropping member 114 , through which the wiring cover 113 and the wiring port 1124 are detachably connected.

[0081] Specifically, an anti-drop hole 115 is provided on the wiring cover 113 at a position corresponding to the anti-drop component 114, and the anti-drop component 114 is limited in the anti-drop hole 115. Therefore, no matter whether the wiring cover 113 is installed or removed, it can be ensured that the anti-drop component 114 will not fall off when the lamp 100 is performed at high altitude, thereby facilitating disassembly and assembly, and greatly enhancing the safety of the installation process.

[0082] Specifically, the anti-dropping member 114 includes a first end portion 1141 , a second end portion 1142 , and a connecting portion 1143 disposed between the first end portion 1141 and the second end portion 1142 .

[0083] The diameter of the first end 1141 and the diameter of the second end 1142 are both larger than the diameter of the connecting portion 1143, the diameter of the anti-drop hole 115 matches the diameter of the connecting portion 1143, and the diameter of the first end 1141 and the diameter of the second end 1142 are also larger than the diameter of the anti-drop hole 115, so that the anti-drop component 114 is limited in the anti-drop hole 115.

[0084] In the extending direction of the connection portion 1143 , the length of the connection portion 1143 is greater than the length of the anti-dropout hole 115 , so that the anti-dropout member 114 has room for movement along the direction of the anti-dropout hole 115 .

[0085] The anti-slip hole 115 extends a section of anti-slip space with a diameter matching the first end portion 1141 toward the end away from the wiring port 1124, and the anti-slip space extends to the surface of the wiring cover 113 and is flush with the wiring cover 113, that is, the height of the anti-slip space is consistent with the height of the first end portion 1141. Therefore, the first end portion 1141 can be hidden within the surface of the wiring cover 113, thereby making the overall structure more complete and beautiful.

[0086] In this embodiment, the wiring cover 113 is provided with a side wall extending in the direction of the wiring port 1124. The side wall is recessed in a direction away from the anti-disengagement hole 115 at the anti-disengagement hole 115, and the anti-disengagement hole 115 is located outside the side wall. With such a setting, the installation of the anti-disengagement member 114 and the pressing of the second sealing ring 1132 do not interfere with each other, making the mechanical connection and the sealing connection of the electrical box 11 more stable and firm.

[0087] In another embodiment, one end of the wiring cover 113 is rotatably connected to the wiring port 1124 through a rotating shaft, and the other end of the wiring cover 113 is snap-connected to the wiring port 1124. With such a setting, when disassembling and assembling the lamp 100, only one end of the wiring cover 113 needs to be lifted.

[0088] In this embodiment, the housing 112 is further provided with a wiring hole 1125 and a waterproof connector 1127.

[0089] Specifically, the wiring hole 1125 is provided on the lower cover 1122 of the electrical box, and the waterproof connector 1127 is provided at one end of the wiring hole 1125 facing the receiving space 1123. The first electrical part 116 enters from the wiring hole 1125, passes through the waterproof connector 1127 and is electrically connected to the wiring terminal 111. The second electrical part 117 is arranged inside the housing 112 and is electrically connected to the first electrical part 116 through the wiring terminal 111. At least a part of the waterproof connector 1127 is located at the wiring port 1124. With such a setting, it is more convenient to operate when installing, disassembling and replacing the first electrical part 116.

[0090] The wiring cover 113 is further provided with a grounding post 1131. The grounding post 1131 is electrically connected to the lower cover 1122 of the electrical box through a grounding wire. The setting of the grounding post 1131 protects the safety of the lamp 100, improves the service life of the lamp 100, and also protects personal safety.

[0091] The power supply module 1 includes: a power supply main body 12 and an electrical connection component 13.

[0092] The power supply main body 12 is arranged inside the electrical box 11 and is detachably connected to the electrical box 11, which is convenient for replacing the power supply main body 12 without having to disassemble and assemble the entire lamp 100.

[0093] Specifically, the electrical box 11 is provided with a receiving portion 118, and the size of the receiving portion 118 matches the size of the power supply main body 12, making the appearance of the electrical box 11 more beautiful.

[0094] Furthermore, the lower cover 1122 of the electrical box is recessed towards the upper cover 1121 of the electrical box to form the receiving portion 118, that is: in this embodiment, the receiving portion 118 is arranged on the lower cover 1122 of the electrical box.

[0095] The electrical connection component 13 includes: a first electrical connector 131 and a third electrical connector 132.

[0096] The first electrical connector 131 is at least partially located within the receiving portion 118, and the third electrical connector 132 protrudes from the first electrical connector 131 out of the power supply body 12. The first electrical connector 131 and the third electrical connector 132 are arranged in opposite directions, and the third electrical connector 132 is electrically connected to the first electrical connector 131.

[0097] A window is formed on the bottom wall 1181 of the receiving portion 118, and the electrical connection assembly 13 penetrates through the bottom wall 1181 from the window. In this embodiment, there are two electrical connection assemblies 13, and correspondingly, there are two windows on the bottom wall 1181.

[0098] A second electrical connector 121 is provided at the corresponding position of the first electrical connector 131 on the power supply body 12, and the first electrical connector 131 is detachably mechanically and electrically connected to the second electrical connector 121. When the power supply body 12 is installed into the receiving portion 118, the first electrical connector 131 abuts against the second electrical connector 121 to achieve mechanical and electrical connection.

[0099] Specifically, the first electrical connector 131 includes an input terminal female terminal 1311 and an output terminal female terminal 1312, and the second electrical connector 121 includes an input terminal male terminal 1211 and an output terminal male terminal 1212. One of the two third electrical connectors 132 is an input terminal connector 1321, and the other is an output terminal connector 1322.

[0100] Furthermore, the output terminal male terminal 1212 is electrically connected to the output terminal female terminal 1312, and the input terminal male terminal 1211 is electrically connected to the input terminal female terminal 1311. When accessing the mains power, the electrical transmission direction is: the first electrical part 116, the terminal block 111, the input terminal connector 1321, the input terminal female terminal 1311, the input terminal male terminal 1211, the output terminal male terminal 1212, the output terminal female terminal 1312, the output terminal connector 1322, the connector 120, the light source module 2.

[0101] The power supply module 1 further includes: a fall prevention member 14, the fall prevention member 14 includes a first head 141, a second head 142 and an extension portion 143, and the power supply body 12 and the electrical appliance box 11 are limited and connected through the fall prevention member 14.

[0102] Specifically, the first head 141 faces the electrical appliance box 11, the second head 142 faces away from the electrical appliance box 11, and the extension portion 143 is arranged between the first head 141 and the second head 142.

[0103] The diameters of both the first head 141 and the second head 142 are greater than the diameter of the extension part 143. A first mounting hole 122 that matches the diameter of the extension part 143 is provided on the power supply main body 12, so that the anti-falling part 14 is limited within the first mounting hole 122. Whether installing or disassembling the power supply module 1, the anti-falling part 14 will not fall off, which is convenient for disassembly and assembly and greatly enhances the safety during the installation process.

[0104] In the extending direction of the extension part 143, the length of the extension part 143 is greater than the length of the first mounting hole 122. Thus, the anti-falling part 14 has a moving space along the direction of the first mounting hole 122. A second mounting hole 119 that matches the diameter of the first head 141 is provided on the electrical box 11, and the height of the extension part 143 plus the height of the first head 141 is equal to the height of the first mounting hole 122 plus the height of the second mounting hole 119.

[0105] A power supply seal 15 is provided between the power supply main body 12 and the electrical box 11. The power supply seal 15 is recessed in a direction away from the anti-falling part 14, and the first mounting hole 122 is located outside the power supply seal 15. With such a setting, the installation of the anti-falling part 14 and the pressing of the power supply seal 15 do not interfere with each other, making both the mechanical connection and the sealing connection of the power supply main body 12 more stable and firm.
