Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, and in particular to an LED outdoor lighting fixture. Background Technology

[0002] LED lighting fixtures are lighting devices that use light-emitting diodes (LEDs) as their light source. Compared to traditional incandescent and fluorescent lamps, LED lighting fixtures have higher energy efficiency, longer lifespan, and a wider range of applications.

[0003] Existing LED lighting fixtures consist of a bracket, a lamp holder, and several lamp bodies. The lamp holder is connected to the bracket, and the lamp holder is fixedly connected to the top of the support column. The lamp bodies are mounted on the lamp holder. Currently, the lamp bodies are connected to the lamp holder using fixing bolts. Adjusting the tilt angle of the lamp body relative to the lamp holder requires loosening the fixing bolts at both ends of the lamp body, then rotating the lamp body until it reaches the desired position, and then retightening the fixing bolts. This process is cumbersome and affects the efficiency of adjusting the lamp body angle, and needs improvement. Utility Model Content

[0004] The purpose of this application is to provide an LED outdoor lighting fixture that improves the efficiency of adjusting the angle of the lamp body.

[0005] This application provides an LED outdoor lighting fixture with the following technical solution: It includes a bracket, the bracket being connected to a lamp holder and a power supply box. The lamp holder is rotatably connected to several lamp bodies, each lamp body being connected to the power supply box via wires. Each lamp body is connected to two rotating rods, each rotating rod being rotatably connected to the lamp holder. One of the rotating rods is slidably connected to an active column. An elastic element is connected between the active column and the rotating rod, with both ends of the elastic element connected to the active column and the rotating rod respectively. The rotating rod is connected to a limiting part, and the active column is provided with a limiting groove for engaging with the limiting part. The lamp holder is connected to a ring block corresponding to one of the rotating rods, the ring block being used to abut against the active column.

[0006] By adopting the above technical solution, when it is necessary to adjust the angle of the lamp body relative to the lamp holder, the active column is pulled away from the rotating rod. The active column separates from the ring block, and the elastic element is compressed, causing elastic deformation and maintaining a tendency to elastically return to its original position. Rotating the active column causes the inner wall of the limiting groove to abut against the limiting part, driving the rotating rod to rotate around its own axis, i.e., the lamp body rotates, thereby adjusting the orientation of the lamp body. After the lamp body is adjusted to the correct position, the active column is released, and the elastic element elastically returns to its original position, forcing the active column to return to its original position, making the active column abut against the ring block, thereby fixing the rotating rod. Compared to adjusting the lamp body by tightening or loosening bolts, this application only requires pulling, rotating, and releasing the active column to adjust the position of the lamp body, which is more convenient.

[0007] Optionally, the rotating rod is provided with a receiving cavity for sliding cooperation with the active column. The limiting part is connected to the inner wall of the receiving cavity. The active column is connected with at least two guide blocks. The rotating rod is provided with guide grooves corresponding to the guide blocks one by one. The guide grooves are in communication with the receiving cavity. One end of the elastic element is connected to the guide block, and the other end is connected to the inner wall of the guide groove.

[0008] By adopting the above technical solution, when the active column slides, the sliding cooperation between the guide block and the guide groove guides and limits the sliding of the active column, thereby improving the stability of the active column's sliding. When the active column rotates, the guide block can abut against the inner wall of the guide groove, increasing the contact area between the active column and the rotating rod, thus making it easier to rotate the rotating rod.

[0009] Optionally, the number of limiting parts is four, the number of limiting grooves is the same as the number of limiting parts, and all the limiting parts are evenly distributed around the axis of the rotating rod.

[0010] By adopting the above technical solution, multiple limiting parts increase the contact area between the rotating rod and the active column, making the limiting parts uniformly stressed, thus making it easier to rotate the rotating rod.

[0011] Optionally, the active column is connected to an abutment ring, and the ring block is connected to a friction pad, the friction pad being used to abut against the abutment ring.

[0012] By adopting the above technical solution, the friction pad increases the friction between the contact ring and the ring block, thus better playing the role of anti-slip.

[0013] Optionally, a handle post is connected to the end of the active post away from the lamp body, and the extension direction of the handle post is perpendicular to the extension direction of the active post.

[0014] By adopting the above technical solution, when the drive column needs to be rotated, the operator can easily pull and rotate the drive column by holding the handle column, which is quite convenient.

[0015] Optionally, the lamp holder is connected to two rotating parts, both of which are rotatably connected to the bracket. The bracket is connected to an adjustment structure, and the lamp holder is adjusted relative to the bracket by the adjustment structure.

[0016] By adopting the above technical solution, the lamp holder adjusts the angle of the lamp holder relative to the support through the adjustment structure. All lamps on the lamp holder rotate with the rotation of the lamp holder, thereby achieving synchronous adjustment of all lamps, which is quite convenient.

[0017] Optionally, the adjustment structure includes an adjustment bolt and a nut threaded onto the adjustment bolt, the bracket is provided with an arc-shaped groove, and the threaded ends of the adjustment bolt all pass through the arc-shaped groove and the lamp holder.

[0018] By adopting the above technical solution, when it is necessary to adjust the angle of the lamp holder relative to the bracket, the adjusting bolt is loosened, so that the adjusting bolt is separated from the bracket, and the lamp holder can rotate around the axis of the rotating part. The rotational cooperation between the adjusting bolt and the arc groove plays a guiding and limiting role in the rotation of the lamp holder relative to the bracket, thereby improving the stability of the lamp holder rotation.

[0019] Optionally, the lamp body includes a lamp housing, a lamp cover, a lamp plate, and a sealing element. The lamp cover, the lamp plate, and the sealing element are all connected to the lamp housing. The lamp cover covers the lamp plate and the sealing element, and the lamp cover abuts against the sealing element. The sealing element is annular and surrounds the lamp plate.

[0020] By adopting the above technical solution, the lamp cover can protect the lamp panel and the sealing component. The annular sealing component surrounds the lamp panel, and the lamp cover abuts against the sealing component, which can provide a good sealing and protection effect for the lamp panel and reduce the entry of external dust, moisture and other substances that may damage the lamp panel.

[0021] Optionally, the inner ring of the seal is provided with a positioning part, and the lamp plate is provided with a positioning groove, which is used to cooperate with the positioning part.

[0022] By adopting the above technical solution, when installing the seal, the positioning part is inserted into the positioning groove, and the outer surface of the positioning part fits against the inner wall of the positioning groove. The cooperation between the positioning part and the positioning groove plays a positioning role in the installation of the seal, thereby enabling the seal to be accurately installed in the corresponding position.

[0023] Optionally, the sealing element is provided with two first abutting ring portions and two second abutting ring portions, the first abutting ring portions surrounding the second abutting ring portions, the two first abutting ring portions respectively abutting against the lamp housing and the lamp cover, and the two second abutting ring portions respectively abutting against the lamp housing and the lamp cover.

[0024] By adopting the above technical solution, both the first and second clamping rings are tightly pressed against the lamp housing and lamp cover, further improving the sealing effect and reducing the entry of external dust, moisture, etc., which could damage the lamp panel.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to adjust the angle of the lamp body relative to the lamp holder, the active column is pulled away from the rotating rod, the active column separates from the ring block, the elastic element is compressed and undergoes elastic deformation and maintains the tendency of elastic reset. Rotating the active column causes the inner wall of the limiting groove to abut against the limiting part and drive the rotating rod to rotate around its own axis, that is, the lamp body rotates, thereby adjusting the orientation of the lamp body. After the lamp body is adjusted to the correct position, the active column is released, the elastic element elastically resets, and the elastic element forces the active column to reset, so that the active column abuts against the ring block, thereby fixing the rotating rod. Compared with adjusting the lamp body by tightening or loosening bolts, this application only requires pulling, rotating, and releasing the active column to adjust the position of the lamp body, which is more convenient.

[0026] 2. When the drive column needs to be rotated, the operator can simply insert one end of their finger through the through hole and pull and rotate the drive column, which is quite convenient. Attached Figure Description

Each guide block 61 is fixedly connected to an elastic element 7, which is a spring. The end of the elastic element 7 away from the guide block 61 is fixedly connected to the inner wall of the guide groove 512.

[0042] Combination Figure 5 , Figure 6 and Figure 7As shown, four limiting parts 513 are fixedly connected to the inner wall of the receiving cavity 511. The limiting parts 513 are elongated and extend in the same direction as the rotating rod 51. The four limiting parts 513 are evenly distributed around the axis of the rotating rod 51. The driving column 6 has limiting grooves 62 that correspond one-to-one with the limiting parts 513, and the limiting parts 513 slide within the limiting grooves 62. The lamp holder 3 is fixedly connected to a ring block 32, which corresponds to the rotating rod 51 on which the driving column 6 is mounted, and the ring block 32 surrounds the rotating rod 51. An abutting ring part 63 is fixedly connected to the outer circumferential surface of the driving column 6. A friction pad 33 is fixedly connected to the side of the ring block 32 away from the lamp holder 3. Due to the influence of the elastic element 7, the abutting ring part 63 is always in contact with the friction pad 33. A handle column 64 is fixedly connected to the end of the active column 6 away from the rotating rod 51. The extension direction of the handle column 64 is perpendicular to the extension direction of the active column 6.

[0044] The implementation principle of an LED outdoor light fixture according to an embodiment of this application is as follows: When it is necessary to adjust the angle of the lamp body 5 relative to the bracket 1, the operator holds the handle column 64 and pulls the active column 6, separating the abutment ring 63 from the friction pad 33. The elastic element 7 is compressed and undergoes elastic deformation, maintaining a tendency to elastically return to its original position. The operator rotates the handle column 64, and the inner wall of the limiting groove 62 abuts against the limiting part 513, causing the rotating rod 51 to rotate around its own axis, thereby causing the lamp body 5 to rotate and adjusting the orientation of the lamp body 5. After the lamp body 5 is adjusted to the correct position, the handle column 64 is released, and the elastic element 7 elastically returns to its original position. The elastic element 7 forces the active column 6 and the abutment ring 63 to return to their original positions, so that the abutment ring 63 abuts against the friction pad 33, thus fixing the lamp body 5.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
