Abstract
Description
Technical Field
[0001] This application relates to the field of LED work light technology, and more specifically, to an LED work light with an adjustable beam angle. Background Technology
[0002] LED work lights are solid-state semiconductor devices that convert electrical energy into visible light; they can directly convert electricity into light. Because of their low power consumption, long lifespan, and environmental friendliness, LED work lights have been widely used in people's lives and work, bringing convenience to their daily routines.
[0003] Existing LED work lights generally consist of a single lamp body and a lamp holder. The lamp body is fixed to the lamp holder, which is then fixed to a bracket or wall during use. Because the lamp body is single, the illumination range is limited, restricting the applicable scenarios. Furthermore, since the lamp body and lamp holder are relatively fixed, when it is necessary to change the illumination direction of the work light, the base must be removed, the appropriate angle adjusted, and then it re-fixed, resulting in low flexibility and inconvenience in using this type of LED work light.
[0004] To address the aforementioned issues, this application provides an LED work light with an adjustable beam angle. Utility Model Content
[0005] The adjustable LED work light provided in this application adopts the following technical solution:
[0006] An adjustable LED work light includes an LED work light body. One side of the LED work light body is provided with a lamp tube and a lampshade, and the other side is provided with a heat dissipation back cover. A bracket is fixedly connected to the lower end of the LED work light body. A U-shaped frame is provided at the lower end of the bracket. A fixing bolt is inserted through the center of the lower end of the U-shaped frame. A connecting rod is inserted through the interior of the bracket. A first positioning groove is formed on the side of the U-shaped frame, and a second positioning groove is formed on the side of the bracket. One end of the connecting rod is threadedly connected to a first component, and the other end of the connecting rod is fixedly connected to a second component. An auxiliary rod is provided on the outer end of the second component.
[0007] Furthermore, the inner wall of the U-shaped frame is rotatably connected to the outer wall of the support, and the first positioning groove and the second positioning groove are correspondingly connected.
[0008] With the above technical solution, the U-shaped frame is fixed by fixing bolts, and the bracket can rotate on the inner wall of the U-shaped frame to adjust the angle of the bracket. The bracket can simultaneously drive the LED work light body to adjust the angle.
[0009] Furthermore, the inner end of the second kit is uniformly fixedly connected with positioning members, which are engaged with the first positioning groove.
[0010] The positioning component is used to fix the angle of the bracket and prevent the bracket from continuously rotating along the inner wall of the U-shaped frame.
[0011] Furthermore, the positioning element passes through the interior of the first positioning groove, and the positioning element passes through the interior of the first positioning groove and engages with the corresponding second positioning groove.
[0012] Through the above technical solution, the positioning component can pass through the interior of the first positioning groove and engage with the corresponding second positioning groove, thereby limiting the position of the bracket.
[0013] Furthermore, a nut is threaded onto the lower outer surface of the fixing bolt, and a fixing device is externally connected to the lower end of the fixing bolt.
[0014] Through the above technical solution, the nut fixes the fixing bolt to form a fixed connection between the fixing bolt and the U-shaped frame. The fixing bolt and the external fixing equipment fix the U-shaped frame, that is, limit and fix the position of the U-shaped frame.
[0015] Furthermore, the lampshade is disposed on the outside of the lamp tube, and the lamp tube is connected to an external power supply cable.
[0016] The above technical solution provides a lampshade to protect the lamp tube from direct contact with the outside environment.
[0017] In summary, this application includes the following beneficial technical effects:
[0018] This application can align and engage the positioning component with the second positioning slot at different angles, thereby adjusting the angle between the bracket and the U-shaped frame to adjust the light emission angle of the lamp tube, thus achieving convenient adjustment of the light emission angle of the LED work light.

[0030] Example:
[0031] This application discloses an adjustable LED work light. Please refer to [link / reference]. Figures 1-6The device includes an LED work light body 1, with a lamp tube 11 and a lamp cover 12 on one side and a heat dissipation back cover 2 on the other side. A bracket 4 is fixedly connected to the lower end of the LED work light body 1, and a U-shaped frame 3 is provided at the lower end of the bracket 4. A fixing bolt 5 is provided through the center of the lower end of the U-shaped frame 3. A connecting rod 6 is provided through the inside of the bracket 4. A first positioning groove 31 is provided on the side of the U-shaped frame 3, and a second positioning groove 41 is provided on the side of the bracket 4. A first kit 61 is threaded to one end of the connecting rod 6, and a second kit 62 is fixedly connected to the other end of the connecting rod 6. An auxiliary rod 63 is provided at the outer end of the second kit 62.
[0032] The inner wall of the U-shaped frame 3 is rotatably connected to the outer wall of the support 4, and the first positioning groove 31 and the second positioning groove 41 are correspondingly connected.
[0033] The U-shaped frame 3 is fixed by the fixing bolts 5. The bracket 4 can rotate on the inner wall of the U-shaped frame 3 to adjust the angle of the bracket 4. The bracket 4 can simultaneously drive the LED work light body 1 to adjust the angle.
[0034] The inner end of the second kit 62 is uniformly fixedly connected with positioning members 621, and the positioning members 621 are engaged with the first positioning groove 31.
[0035] The positioning element 621 is used to fix the angle of the bracket 4 to prevent the bracket 4 from continuously rotating along the inner wall of the U-shaped frame 3.
[0036] The positioning element 621 passes through the interior of the first positioning groove 31 and engages with the second positioning groove 41.
[0037] The positioning element 621 can pass through the interior of the first positioning groove 31 and engage with the second positioning groove 41, thereby limiting the position of the bracket 4.
[0038] A nut 51 is threaded onto the lower outer surface of the fixing bolt 5, and a fixing device is connected to the lower end of the fixing bolt 5.
[0039] Nut 51 secures the fixing bolt 5 to form a fixed connection between the fixing bolt 5 and the U-shaped frame 3. The fixing bolt 5 and the external fixing equipment fix the U-shaped frame 3, that is, limit and fix the position of the U-shaped frame 3.
[0040] The lampshade 12 is located on the outside of the lamp tube 11, and the lamp tube 11 is connected to an external power supply.
[0041] The lamp cover 12 is used to protect the lamp tube 11 and prevent the lamp tube 11 from directly contacting the outside world.
[0042] The implementation principle of this embodiment is as follows: When it is necessary to adjust the light emission angle of the lamp tube 11, firstly, rotate the first assembly 61 to separate it from the connecting rod 6. Then, pull the auxiliary rod 63 outward so that the positioning member 621 is driven by the second assembly 62 to sequentially disengage from the interior of the second positioning groove 41 and the first positioning groove 31, so that the movement of the connecting rod 6 is not blocked by the first assembly 61. Then, the bracket 4 can be moved so that the bracket 4 rotates along the inner wall of the U-shaped frame 3. Under the action of the connecting rod 6, the bracket 4 is always restricted to a fixed position on the inner wall of the U-shaped frame 3. After the angle of the bracket 4 is adjusted to the appropriate position, the auxiliary rod 63 can be pushed so that the positioning member 621 passes through the interior of the first positioning groove 31 and enters the second positioning groove 41 via the second kit 62. Then, the first kit 61 can be rotated in the opposite direction so that it rotates along one end of the connecting rod 6 until the inner end of the first kit 61 is attached to one side of the U-shaped bracket 3, thereby limiting the position of the connecting rod 6 and preventing the connecting rod 6 from moving horizontally. At this time, under the action of the positioning member 621, the angle position of the bracket 4 can be limited and fixed, thus completing the adjustment and fixing of the light emission angle of the lamp tube 11.
[0043] 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.
