Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps, and in particular to an LED lamp whose irradiation position can be easily adjusted. Background Art

[0002] LED lights are lighting devices that generate light when an electric current flows through a semiconductor material. Compared to traditional incandescent and fluorescent lamps, LEDs offer many significant advantages, such as high efficiency, long life, and environmental friendliness. LED lights that can be easily adjusted typically feature flexible adjustments to the light source's angle, direction, or focal length. These lamps not only allow precise control of the light's projection area based on actual needs, but also improve lighting efficiency and provide a better user experience.

[0003] Prior art publication CN117588721A discloses an LED lamp with a universal sliding structure that allows the lamp body to rotate freely. This rotation also drives a first conductor to connect with a second conductor to adjust the lamp's operating state. This eliminates the need for the two steps of pressing a switch and rotating the lamp body, making operation very convenient. The LED lamp assembly can be adjusted 360 degrees and provides targeted lighting for the product, making operation very convenient.

DETAILED DESCRIPTION

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] like Figures 1-9 An LED lamp that is easy to adjust the irradiation position is shown, including a mounting base 1, a rotating base 2 is rotatably connected to the lower side of the mounting base 1, a protective cover 3 is rotatably connected to the rotating base 2, a transmission mechanism 4 is rotatably connected to the inner wall of one side of the protective cover 3, a lamp holder 5 is slidably fitted on the inner wall of the protective cover 3, a U-shaped LED lamp 6 is threadedly connected to the lamp holder 5, two push rod groups 7 are provided on the lamp holder 5, a U-shaped lamp tube maintenance mechanism 8 is provided between the other ends of the two push rod groups 7, and a blocking cover 9 is rotatably connected to the opening at the bottom end of the protective cover 3.

[0021] like Figure 3As shown, one end of rotating base 2, located within mounting base 1, is fixedly connected to motor A201, which is fixedly connected to the inner wall of mounting base 1. Motor B202 is fixedly connected to the outer end of rotating base 2. Motor A201 drives rotating base 2 to rotate to the desired angle, and then motor B202 drives protective cover 3, which is connected to rotating block 301, to rotate, placing U-shaped LED lamp 6 in the desired illumination position.

[0022] like Figure 4 As shown, a rotating block 301 is fixedly connected to the top of the protective cover 3. The rotating block 301 is rotatably connected to the rotating base 2 via a pin, and one end of the pin is fixedly connected to the output end of the motor B202. A threading hole 302 is opened at the top of the protective cover 3. The threading hole 302 facilitates the threading and wiring of the wires.

[0023] By providing the protective cover 3 and the blocking cover 9, the U-shaped LED lamp 6 can be retracted into the protective cover 3 for protection when not in use, thereby reducing the exposure to external factors such as collision, scratches or falls when not in use. After being retracted, the U-shaped LED lamp 6 is shielded by the protective cover 3, preventing dust, stains, water droplets and other substances from directly contacting the U-shaped LED lamp 6, reducing damage to the U-shaped LED lamp 6 caused by external environmental factors, greatly improving the safety, durability, and convenience of cleaning of the lamp, and extending its service life.

[0024] like Figure 5 As shown, the transmission mechanism 4 includes a threaded rod 401, which is rotatably connected to the inner wall of the protective cover 3 through the threaded rod 401, and a motor C402 is fixedly connected to the top of the threaded rod 401. The motor C402 is fixedly connected to the protective cover 3, and a driving wheel 403 is fixedly connected to one end of the threaded rod 401 located inside the protective cover 3.

[0025] A driven wheel 404 is meshed and driven on one side of the driving wheel 403. A transmission rod 405 is fixedly connected to the driven wheel 404. The transmission rod 405 is rotatably connected to the inner wall of the protective cover 3. A rotating sleeve 406 is slidingly provided on the outer wall of the transmission rod 405. The outer wall of the rotating sleeve 406 has an inclined structure and an annular groove 407. When the lamp holder 5 drives the U-shaped LED lamp 6 out of the protective cover 3, the driving wheel 403 on the threaded rod 401 rotates the transmission rod 405 connected to the driven wheel 404. The transmission rod 405 then rotates the rotating sleeve 406. At this time, the rotating sleeve 406 drives the guide head frame 703 to reciprocate up and down through the annular groove 407.

[0026] like Figure 6As shown, a moving block 501 is fixedly connected to one end of the lamp holder 5, the moving block 501 is threadedly connected to the threaded rod 401, the moving block 501 is rotatably connected to the rotating sleeve 406, and a transmission head 502 is fixedly connected to the other side of the lamp holder 5. A plurality of inclined grooves 503 are opened on the lamp holder 5.

[0027] like Figure 7 As shown, a transmission wheel 701 is fixedly connected to the top of the push rod assembly 7. A transmission rack 702 is meshed and driven on one side of the transmission wheel 701. The transmission rack 702 is in sliding contact with the lamp holder 5. A guide head frame 703 is meshed and driven between the two transmission racks 702. One end of the guide head frame 703 is in sliding contact with the inner wall of the annular groove 407. Hinges 704 are rotatably connected to both ends of the push rod assembly 7. The upper and lower hinges 704 are respectively fixedly connected to the lamp holder 5 and the U-shaped lamp tube maintenance mechanism 8. The transmission rack 702 on the guide head frame 703 drives the push rod assembly 7 connected to the transmission wheel 701 to rotate, thereby driving the movable base 801 to reciprocate.

[0028] like Figure 8 As shown, the U-shaped lamp tube maintenance mechanism 8 includes a movable base 801, which is provided with a plurality of sliding grooves 806. Sliders 802 are slidably mounted on the inner walls of the sliding grooves 806. A contact rod 803 is fixedly mounted on the top of the slider 802. The contact rod 803 slidably engages with the inner wall of the inclined groove 503. A tension spring 804 is fixedly mounted on one side of the slider 802. The other end of the tension spring 804 is fixedly mounted on the inner wall of the movable base 801. A fixed rod 805 is fixedly mounted on one side of the slider 802. A sponge 807 is fixedly mounted on one side of the fixed rod 805. The sponge 807 is slidably mounted in contact with the U-shaped lamp tube of the U-shaped LED lamp 6. When the movable base 801 moves, the contact rod 803 no longer contacts the inner wall of the inclined groove 503. The tension spring 804 drives the slider 802 to move, causing the slider 802 to drive the sponge 807 on the fixed rod 805 into contact with the U-shaped lamp tube of the U-shaped LED lamp 6. The sponge 807 is provided with a groove adapted to the U-shaped lamp tube of the U-shaped LED lamp 6 .

[0029] like Figure 9 As shown, one end of the cover 9 extends through the outer wall of the protective cover 3 and into the interior, where it is fixedly connected to a transmission shaft 901. The outer wall of the transmission shaft 901 is provided with a transmission groove 902. The upper end of the transmission groove 902 is arranged in a spiral structure, and the lower end of the transmission groove 902 is arranged in a linear structure. The inner wall of the transmission groove 902 is arranged in sliding contact with the outer wall of the transmission head 502. The transmission head 502 on the lamp holder 5 slides within the transmission groove 902, thereby driving the transmission shaft 901 to rotate, and the transmission shaft 901 then drives the connected cover 9 to open.

[0030] Working principle: When the U-shaped LED lamp 6 is needed, the motor C402 is used to drive the connected threaded rod 401 to rotate. At this time, the threaded rod 401 will drive the lamp holder 5 connected to the moving block 501 to move. At this time, the transmission head 502 on the lamp holder 5 will slide in the transmission groove 902, thereby driving the transmission shaft 901 to rotate. At this time, the transmission shaft 901 will drive the connected cover 9 to open; When the lamp holder 5 drives the U-shaped LED lamp 6 to move out of the protective cover 3, the driving wheel 403 on the threaded rod 401 drives the transmission rod 405 connected to the driven wheel 404 to rotate, and then the transmission rod 405 drives the rotating sleeve 406 to rotate. At this time, the rotating sleeve 406 drives the guide head frame 703 to move up and down through the annular groove 407. At this time, the transmission rack 702 on the guide head frame 703 drives the push rod group 7 connected to the transmission wheel 701 to rotate, thereby driving the moving seat 801 to move back and forth. When the moving seat 801 moves, the contact rod 803 does not align with the inner surface of the inclined groove 503. When the U-shaped LED lamp 6 is completely moved out, the push rod assembly 7 drives the U-shaped lamp tube maintenance mechanism 8 to move to the uppermost position. At this time, the inclined groove 503 on the lamp holder 5 drives the slider 802 connected to the contact rod 803 to move, so that the sponge 807 is out of contact with the U-shaped LED lamp 6. Then, when the irradiation position of the U-shaped LED lamp 6 needs to be adjusted, the motor A201 is used to drive the rotating seat 2 to rotate to the appropriate angle, and then the motor B202 is used to drive the protective cover 3 connected to the rotating block 301 to rotate, so that the U-shaped LED lamp 6 is in the required irradiation position.
