Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED lighting technology, and in particular to an LED light. Background Technology
[0002] LED streetlights are widely used due to their energy-saving and long lifespan advantages. LED streetlights typically have an electrical box containing electrical components such as a driver and surge protector. For ease of installation and maintenance, the electrical box usually has an openable cover.
[0003] Existing electrical boxes are mostly formed by sheet metal welding or die casting. Sheet metal structures are complex, making it difficult to guarantee sealing, and their dimensions are difficult to change once finalized. Die casting structures offer high strength but require expensive molds, and different sizes of boxes require different molds, resulting in high costs and poor flexibility. Furthermore, existing electrical box covers mostly use hinged flip-top or screw-locking mechanisms. Hinged flip-top mechanisms are complex, space-consuming, and inconvenient to operate on streetlight poles; screw-locking mechanisms require disassembling multiple screws, which is cumbersome, prone to screw loss, and repeated disassembly can lead to stripped threads. Additionally, existing cover fixing methods are prone to loosening under long-term vibration, leading to abnormal noise and component wear. Utility Model Content
[0004] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an LED light that solves the technical problems of complex electrical box structure, inconvenient installation and operation of cover plate structure, and easy loosening under long-term vibration environment, resulting in abnormal noise and component wear.
[0005] (II) Technical Solution The purpose of this utility model is to provide an LED lamp, which includes a lamp arm, a main profile rod, a lighting module, and an electrical box. The lamp arm, the lighting module, and the electrical box are all disposed on the main profile rod. The electrical box is disposed between the lamp arm and the lighting module. The electrical box includes a profile box body, a front cover, a rear cover, and a cover plate. The profile box body includes a first molded body and a second molded body, both of which are extruded structures. They are symmetrically disposed on the main profile rod to form a box cavity. The front cover and the rear cover are respectively disposed at both ends of the profile box body. The sides of the box cavity are... The inner wall is provided with a sliding groove, and the two sides of the cover plate are movable and pull-out to match the sliding groove; the inner side of the front cover is provided with a protruding limiting lug, and the limiting lug is provided with a limiting groove; the rear part of the cover plate is riveted with a first stud and a second stud, wherein, when the cover plate and the profile box are opened, when the cover plate is pulled forward to a predetermined position, the end of the first stud abuts against the inner side of the rear cover and forms a limit to prevent the cover plate from completely leaving the box cavity; when the cover plate and the profile box are closed, the second stud is located above the limiting groove of the limiting lug.
[0006] Preferably, the profile box body is further provided with a driving power supply, a limiting plate and a surge protector. The surge protector is located adjacent to the driving power supply, and the limiting plate is located at the upper end of the driving power supply by means of end mounting bolts.
[0007] Preferably, both the first and second shapes are aluminum extrusion molding structures, and the box cavity formed by the two shapes is provided with screw slots, the number of which is four or more, and they are symmetrically arranged.
[0008] Preferably, the upper end of the box cavity is open, and the sliding groove is disposed on both sides of the open.
[0009] Preferably, the lower end face of the first and second shapes is provided with an embedding groove, and the upper and lower ends of the embedding groove are provided with limiting protrusions.
[0010] Preferably, the limiting groove is a blind hole structure.
[0011] Preferably, both the front cover and the rear cover are provided with screw holes, and the number of screw holes is four or more, and they are arranged symmetrically.
[0012] Preferably, the first stud is a blind hole stud with an internal ground wire.
[0013] (III) Beneficial Effects
[0014] 1. The profile box body is produced by extrusion molding. Only one set of molds is needed to produce profiles of any length. It can be flexibly cut according to the number and size of internal electrical components, realizing "customization on demand". This greatly reduces mold investment and material inventory, and lowers production costs. 2. The cover is removable and installed on the profile box body. During maintenance, it can be opened and closed by pulling it out. Maintenance of the components inside the box cavity can be carried out without complicated operations, making the operation simple and quick. 3. When the cover is closed, the second stud corresponds to the limiting lug of the front cover. The screw is inserted and passes through the second stud to extend into the limiting groove for limiting. When the cover is opened, when the cover is pulled forward to the predetermined position, the end of the first stud abuts against the inner side of the rear cover to form a limit, preventing the cover from completely leaving the box cavity and avoiding loss of the cover. 4. When the cover plate is pulled back to the closed position, the screw can pass through the second stud and extend into the limiting groove. By tightening the screw, its tail is pressed against the bottom of the limiting groove, thereby pushing one end of the cover plate upward and making it fit tightly against the slide groove to eliminate gaps and avoid vibration and abnormal noise. As can be seen from the above, compared with the existing technology, the whole structure is simple and compact, without the need for complex hinges or additional locking mechanisms, the manufacturing process is simple and the cost is low, making it very suitable for mass production.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0019] The following is in conjunction with the appendix Figures 1 to 7 To further describe, this utility model discloses an LED lamp, including a lamp arm 1, a main profile rod 2, a lighting module 3, and an electrical box 4. In this embodiment, the lamp arm 1, the lighting module 3, and the electrical box 4 are all inserted into a pre-set connection space (such as an embedding groove 43, a slot, etc.) of the three through the main profile rod 2, and then connected to it respectively by screws inserted and passing through the main profile rod 2. In terms of installation structure, the electrical box 4 is installed between the lamp arm 1 and the lighting module 3. Specifically, the lamp arm 1 is installed on one side of the front cover 5 of the electrical box 4, and the lighting module 3 is located on one side of the rear cover 6 of the electrical box 4. The lighting module 3 includes conventional components such as a lens, LED beads, a PCBA board, and a heat sink. Its installation structure and circuit connection are all existing technologies. In this embodiment, the electrical box 4 includes a profile box body 40, a front cover 5, a rear cover 6, and a cover plate 7. The profile box body 40 includes a first molded body 45 and a second molded body 46, both of which are extruded. The first molded body 45 and the second molded body 46 are symmetrically arranged on the main profile rod 2, forming a box cavity 41 for accommodating components. The front cover 5 and the rear cover 6 are respectively arranged at both ends of the profile box body 40 for protecting the internal structure. The height of the rear cover 6 is less than the height of the front cover 5 to reserve clearance space during the sliding process of the cover plate 7. The inner walls on both sides of the upper opening of the box cavity 41 are symmetrically provided with sliding grooves 48 along the length direction. During installation, the flat cover plate 7 is inserted into the sliding groove 48. The cover plate 7 can be movably pulled out and matched with the sliding groove 48 to limit the upper and lower positions of the cover plate 7 while maintaining the space for the front and back movement of the cover plate 7, thus forming the function of opening and closing the cover plate 7 by pulling it out. Furthermore, the inner side of the front cover 5 is provided with a protruding limiting lug 50, and a limiting groove 51 is provided in the limiting lug 50. The shape of the limiting groove 51 can be either circular or elongated. A first stud 70 and a second stud 71 are provided at the rear of the cover plate 7 by means of press riveting. In this embodiment, the first stud 70 is located adjacent to the second stud 71, and the length of the first stud 70 is longer than that of the second stud 71. When the cover plate 7 and the profile box 40 are opened, when the cover plate 7 is pulled towards the rear cover 6 to a predetermined position, the end of the first stud 70 abuts against the inner side of the rear cover 6 and forms a limiting, preventing the cover plate 7 from completely detaching when pulled out. This avoids the risk of losing the cover plate 7. When the cover plate 7 is closed with the profile box 40, the cover plate 7 is pulled forward to the closed position in the direction of the front cover 5. Through the above process, the cover plate 7 can be opened to maintain the internal components without disassembling any parts. In addition, the second stud 71 is located above the limiting groove 51 of the limiting lug 50. The hand screw 11 can pass through the second stud 71 and extend into the limiting groove 51. By tightening the hand screw 11, its tail is pressed against the bottom of the limiting groove 51, thereby using the hand screw 11 to push one end of the cover plate 7 upward, so that it fits tightly with the slide groove 48, eliminating the gap between the cover plate 7 and the slide groove 48, so as to avoid vibration and abnormal noise.
[0020] In a preferred embodiment, the profile box 40 is further provided with a driving power supply 8, a limiting plate 10 and a surge protector 9. The surge protector 9 is located adjacent to and electrically connected to the driving power supply 8, while the driving power supply 8 is electrically connected to the lighting module 3. The limiting plate 10 is connected to the bottom of the profile box 40 by bolts at both ends and spans across the upper end of the driving power supply 8 to limit the driving power supply 8. In addition, the driving power supply 8 and the surge protector 9 are both waterproof components.
[0021] In a preferred embodiment, both the first body 45 and the second body 46 are aluminum extrusion molding structures. The box cavity 41 formed by the two is provided with screw grooves 42. There are four or more screw grooves 42, which are symmetrically arranged. The front and rear ends of the screw grooves 42 are used to fix the front cover 5 and the rear cover 6, respectively. Specifically, screws are inserted and pass through the through holes reserved in the front cover 5 and the rear cover 6 to connect with the screw grooves 42.
[0022] In a preferred embodiment, the upper end of the cavity 41 is open, and the slide 48 is provided on both sides of the inner wall of the open 47. The open 47 serves as an inspection port for internal components, and the cover plate 7 provided in the slide 48 serves as a closed door to facilitate later component maintenance.
[0023] In a preferred embodiment, the lower end face of the first body 45 and the second body 46 is provided with an embedding groove 43. The upper and lower ends of the embedding groove 43 are provided with limiting protrusions 44. When the main profile rod 2 is inserted into and passes through the embedding groove 43, it is limited by the limiting protrusions 44 on both sides of the embedding groove 43. Then, it is fixed by inserting a screw into and passing through the embedding groove 43 and the main profile rod 2.
[0024] In a preferred embodiment, the limiting groove 51 is a blind hole structure. The limiting groove 51 is a smooth hole with a diameter slightly larger than the diameter of the screw that can be screwed into the second stud 71, which reduces the assembly difficulty and improves adaptability.
[0025] In a preferred embodiment, both the front cover 5 and the rear cover 6 are provided with screw holes 52. There are four or more screw holes 52, which are symmetrically arranged. During installation, screws are inserted through the screw holes 52 and tightened into the screw slots 42 on the profile box body 40 to fix the front cover 5 and the rear cover 6 respectively. In this embodiment, the rear cover 6 is flat.
[0026] In a preferred embodiment, the first stud 70 is a blind hole stud with a ground wire 12 locked inside. The other end of the ground wire 12 is connected to the screw on the main profile rod 2 and the profile box 40 to achieve grounding through the first stud 70. This achieves both physical limiting and electrical safety.
[0027] It should be further explained that the profile box 40 is a non-waterproof structure. The length of the profile box 40 can be determined by cutting according to the size of the device contained in the box cavity 41, and the length of the cover plate 7 will change accordingly. Both the front cover 5 and the rear cover 6 are pre-set with wire holes. Both can be made of PC plastic injection molding, which ensures strength, achieves insulation and further reduces costs; or die casting aluminum can be selected to meet the requirements of higher strength. The two manufacturing methods provide flexible design options.
[0028] Although embodiments of the present invention have been shown above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications and variations to the above embodiments, but such modifications are all included within the broad scope of the foregoing disclosure, drawings and claims.
