Description

Technical Field

[0001] This invention belongs to the field of lighting technology, and specifically relates to a work lamp. Background Technology

[0002] Work lights are high-efficiency LED lighting fixtures used both indoors and outdoors. They can be widely used in industrial plants, production workshops, supermarkets, sports and entertainment venues, and warehouses. In some scenarios, work lights often require a support bracket to ensure optimal lighting performance. In this case, the bracket needs a horizontal support rod at the top that is compatible with the base structure of the work light to secure it. To ensure the work light's battery life, some work lights, in addition to built-in or external batteries, can also be directly powered by an AC power adapter or have their batteries charged via an AC power source. However, power adapters are often bulky and inconvenient to carry.

[0003] Chinese patent CN217382733U discloses a multi-source work light comprising a vertically extending lamp post and a head. The head includes a first lamp body and a second lamp body group mounted at the top of the lamp post. The second lamp body group includes at least two second lamp bodies. The first lamp body and each of the second lamp bodies are arranged side by side in a horizontal direction. The first lamp body is located on one side of the second lamp body group. In the second lamp body group, the second lamp body adjacent to the first lamp body is rotatably connected to the first lamp body, while each adjacent second lamp body is rotatably connected to each other. Each lamp body can rotate relative to its adjacent lamp body about a horizontally extending first center line. The work light technology disclosed in this patent has the drawback that the lamp head cannot be used detached from the bracket and cannot be charged with AC power when the battery pack is dead or when long-term lighting is required. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a work light that uses a power adapter as a horizontal support rod, and that the work light can be used independently without the support bracket.

[0005] The objective of this invention can be achieved through the following technical solution: a work lamp, characterized in that it comprises:

[0040] The following are specific embodiments of the present invention, in conjunction with the appendix. Figure 1-10 The technical solution of the present invention will be further described below, but the present invention is not limited to the following embodiments.

[0041] A work light includes: a bracket 100, a power adapter 200, a base 300, and a lamp head assembly 400. The power adapter 200 is disposed on the top of the bracket 100, the base 300 is disposed on the power adapter 200 and electrically connected to the power adapter 200, and the lamp head assembly 400 is disposed on the base 300. By including the power adapter 200, the work light can be powered by AC power. Distributing the power adapter 200 on the top of the bracket 100 for mounting the base 300 makes the power adapter 200 easy to carry, and eliminates the need for the horizontal support rod originally used to mount the base 300, reducing costs.

[0042] In this embodiment, the bracket 100 includes a vertical support rod 110 and three legs 130. Each leg 130 is equally spaced around the vertical support rod 110. The upper end of each leg 130 is rotatably connected to the vertical support rod 110, and the middle part is hinged to the vertical support rod 110 via a support rod 131. In use, each leg 130 is spread out by the support rod 131, at which time the bracket 100 can support the base 300 and the lamp head assembly 400, allowing the work lamp to be placed stably. When storing, each leg 130 is closed to reduce the storage volume of the work lamp.

[0043] A connecting seat 120 is provided at the top of the vertical support rod 110. The connecting seat 120 is vertically inserted into the central through hole of the vertical support rod 110. A stud 121 is provided at the center of the connecting seat 120. The power adapter 200 includes a housing 210 and a connector 220. A mounting hole 211 is provided on the lower surface of the housing 210. The connector 220 is disposed in the mounting hole 211. In this embodiment, the connector 220 and the mounting hole 211 are interference-fitted. In other embodiments, the connector 220 can also be installed in the mounting hole 211 in other ways. A threaded hole 221 is provided on the connector 220. The connector 220 and the stud 121 on the connecting seat 120 are threadedly connected. By providing a stud 121 on the connector 120 and a connector 220 in the housing 210 of the power adapter 200, and providing a threaded hole 221 in the connector 220, the connector 120 and the connector 220 are threadedly connected, which allows the power adapter 200 and the bracket 100 to be easily connected or disassembled.

[0044] A power output interface 230 is provided on the upper surface of the housing 210.

By providing the power output interface 230 on the upper surface of the housing 210 of the power adapter 200 and the second power input interface 331 on the bottom surface of the base 300, and by detachably connecting the power output interface 230 and the second power input interface 331, the power cord between the power adapter 200 and the base 300 is eliminated, further reducing costs.

[0045] The base 300 is shaped like a horizontal U, including a mounting part 310, a connecting part 320, and a placement part 330 connected in sequence. The connecting part 320 is disposed between the mounting part 310 and the placement part 330. The projected area of ​​the mounting part 310 relative to the horizontal plane is smaller than that of the placement part 330 relative to the horizontal plane. A hook 332 and a groove 333 are provided on the bottom surface of the placement part 330, allowing the work light to be suspended. The groove 333 is used to accommodate the hook 332, preventing the hook 332 from being exposed. By setting the projected area of ​​the mounting part 310 relative to the horizontal plane to be smaller than that of the placement part 330 relative to the horizontal plane, the work light is placed more stably when the bracket 100 is not used.

[0046] This work light also includes a battery pack 500.

By providing the third power input interface 311 on the mounting part 310 and detachably connecting the battery pack 500 to the third power input interface 311, this work light can be used independently without the bracket 100. Furthermore, by providing the charging coil in the placement part 330, the space on the base 300 can be utilized for wireless charging of electronic products such as mobile phones 600.

[0047] The lamp holder assembly 400 includes a lamp holder 410, a rotating member 420, and several lamp holders 430. The rotating member 420 is rotatably connected to the lamp holder 410, and the lamp holders 430 are hinged to the rotating member 420. The lamp holders 430 can be closed or opened relative to the rotating member 420. The lamp holder 410 is used to support the rotating member 420 and the lamp holders 430 and control the switching of the lamp holders 430. In this embodiment, three lamp holders 430 are provided. The lamp holders 430 are hinged to the rotating member 420 and are evenly distributed around the circumference of the rotating member 420. The rotating member 420 is hinged to the lamp holder 410. The pitch angle of the lamp holders 430 can be adjusted by rotating the rotating member 420. The lamp holders 430 can be closed or opened by rotating the lamp holders 430, thereby meeting the lighting needs of various scenarios.

[0048] The control method of this bracket 100 lamp is as follows: when the bracket 100 is used and the usage scenario has AC power, the power adapter 200 is connected to the AC power source, and the power adapter 200 supplies power to the lamp head 430, charging coil, and USB interface 321. At this time, if the battery pack 500 is not fully charged, it is charged at the same time. When the bracket 100 is used but the usage scenario does not have AC power or the bracket 100 is not used, the battery pack 500 supplies power to the lamp head 430, charging coil, and USB interface 321.

[0049] The specific embodiments described herein are merely illustrative of the spirit of the invention.
